FIG. 1. The bottom right image shows fibroblasts from a child affected with CMD. Top images and bottom left image show fibroblasts from unaffected family members of a CMD affected child. Laminin levels are labeled with rabbit anti-laminin antibodies. Nuclei are stained with DAPI.
FIG. 2. Laminin binds to glycosylated lipids on the surface of a cell. Normal glycosylation of cell surface lipids allows fibroblasts to bind to laminin. Fibroblasts in muscular dystrophy patients are defective in glycosylation, and hence, are unable to bind to laminin.
FIG. 3. Cells from a rare disease patient are added to each well of a 384-well plate. A different active drug or nutraceutical was added to each well. Laminin was labeled with rabbit anti-laminin antibodies. Plates were scanned by an automated confocal microscope. Experiments were performed on 4 plates in duplicate.
FIG. 4. Fibroblasts from a CMD-affected patient (middle) are markedly lower in laminin binding, as compared to the patient's unaffected brother (left). Once the patient's fibroblasts are treated with SAHA, a hit identified in the screen, laminin binding is normalized to the levels of the patient's unaffected brother. Laminin was labeled with rabbit anti-laminin antibodies. Nuclei are stained with DAPI.
FIG. 5. Immortalized fibroblasts from a CMD patient display increased levels of laminin binding upon treatment with Givinostat an HDAC inhibitor, structurally similar to those identified in the screen as “hits” from an HCS. A dose response curve for Givinostat was prepared measuring laminin staining intensity at various concentrations of the compound. Laminin was labeled with rabbit anti-laminin antibodies. Nuclei are stained with DAPI.
FIG. 6. Fibroblasts were obtained from CMD patients with either low (CMD-FKRP) laminin binding, mid-range laminin binding (LGMD/CMD-FKRP), or closer to normal (LGMD-FKRP) laminin binding. Trichostatin A, identified as a “hit” by the HSC screens described herein, increased laminin binding in fibroblasts with various levels of laminin binding deficiency. Laminin was labeled with rabbit anti-laminin antibodies. Nuclei are stained with DAPI.
FIG. 7. This figure exemplifies methods by which various dysfunctional cell types in a rare disease patient can be studied with the methods and platforms disclosed herein in order to identify drugs and drug combinations that will reverse an optically visible rare disease phenotype in each separate cell type.
FIG. 8. Fibroblasts from a CMD patient with two deficient copies of the POMT1 gene show visibly reduced laminin binding as compared to the patient's heterozygous mother, who carries only one deficient copy of POMT1. Laminin is labeled with rabbit anti-laminin antibodies. Nuclei are stained with DAPI.
FIG. 9. Fibroblasts were taken from an FKRP deficient CMD patient and a POMT1 deficient CMD patient. Addition of Trichostatin A resulted in increased laminin binding in fibroblasts from the CMD-FKRP patient; however, this compound did not result in visibly increased laminin binding in fibroblasts from the CMD-POMT1 patient. Laminin is labeled with rabbit anti-laminin antibodies. Nuclei are stained with DAPI.
FIG. 10. iPSC cell lines were generated by obtaining fibroblasts from a LGMD/CMD-FKRP patient and a CMD-POMT1 patient. The fibroblasts were transfected with polycistronic lentiviral cassettes expressing OCT4. Each cell line expressed OCT4 and NANOG markers of cell dedifferentiation at a level similar to that of the H9 human embryonic stem cell (hESC) line.DETAILED DESCRIPTION
It is estimated that bringing a new drug to market can take about 15 years and cost about $800 million. A significant portion of this time and cost results from the need to generate pharmacokinetic and safety data for the approval process. Due to the high costs associated with bringing new drugs to market and limited resources, companies often focus on commercializing drugs that will provide the highest return on investment. As a result of this focus, limited funds and resources are allocated to investigating treatments for rare diseases. There is a significant unmet need for novel and efficacious treatments for rare diseases that can be brought to market quickly and inexpensively. There are currently thousands of known drugs and nutraceuticals, for which pharmacokinetic and safety data has previously been generated. Repurposing these drugs and nutraceuticals satisfies the unmet need for treatments for rare diseases in a cost-effective manner.
There is a need for novel methods and platforms for identifying known drugs and nutraceuticals for repurposing to treat rare diseases. These methods should be fast, personalizable, and reduce the costs and steps associated with identifying known drugs/nutraceuticals for repurposing. Certain rare diseases are associated with optically-visible cell phenotypes. As opposed to traditional biochemical assays, phenotypic screens based on optically-visible phenotypes enable medical professionals to visualize (a) the phenotypic response of a known drug/nutraceutical and (b) the whole cell effects (e.g., toxicity and dose response) of the known drug/nutraceutical. The simultaneous production of biochemical and whole cell data reduces the time, number of assays, and costs needed to identify known drugs/nutraceuticals that may be repurposed to treat rare diseases. Utilizing High Content Screening further reduces the time needed to identify known drugs/nutraceuticals that are repurposed to treat rare diseases. Disclosed herein, are methods and platforms that satisfy the aforementioned needs.
Theranostics Platforms
The platforms disclosed herein identify drug and/or nutraceutical candidates for normalizing, or partially normalizing, a rare-disease associated with an optically-visible cell phenotype. The drug/nutraceutical library includes known drugs, metabolites of known drugs, and/or nutraceuticals. Examples of cell phenotypes that are, or in the alternative are made optically-visible, include cell morphology, nuclear morphology, morphology of the plasma membrane, the morphology of any cytosolic organelle. Where the cell phenotype is not naturally optically-visible, the phenotype is rendered optically-visible due to the use of an optically-visible dye/label (e.g., a fluorescent dye). Individuals that will benefit from these platforms are symptomatic (including those with limited symptoms), or asymptomatic.
The platforms comprise a rare disease cell with an optically-visible cell phenotype, and a means for visualizing the response of a cell having an optically-visible rare-disease cell phenotype to a drug or nutraceutical from the drug/nutraceutical library to identify drug/nutraceutical hits. The platforms are optionally used to establish dose-response curves for the hits. The platforms also optionally include genotyping individuals to determine if they would benefit from the platforms, for example to determine which strain of a rare disease an individual has, what disease an individual has, if an individual is predisposed to develop a rare disease.
The means for visualizing the response of a cell having an optically-visible rare-disease cell phenotype to a drug or nutraceutical from the drug/nutraceutical library is optionally a microscope with sufficient magnifying power to visualize one cell in a plurality of cells. The images captured by the microscope are optionally stored in electronic memory. The microscope is optionally part of a High Content Screening (HCS) system with automated liquid handling and automated plate handling, image analysis software. The system optionally has software that analyzes degrees of response of the cells to a drug or nutraceutical and dose-response curves.
Any hits identified by these platforms are used to create a Rare Disease Specific Drug Library for the rare disease. The Rare Disease Specific Drug Library is optionally further personalized for each individual with the rare disease, for example some drugs will be eliminated, and/or different drug combinations/dosages will be identified for each individual.
The cells for use with the platforms are optionally naturally-occurring cells obtained from a subject with a rare disease cell phenotype, cells derived from stem cells obtained from a subject with a rare disease cell phenotype, or cells derived from iPS cells produced from cells from a subject with a rare disease cell phenotype. The cells are optionally recombinant cells. In some alternatives, the cells are derived from a personalized cell line established from an individual with an optically-visible rare-disease cell phenotype. In other alternatives, the cells are derived from a general cell line established from a cell obtained from a donor individual with an optically-visible rare-disease cell phenotype. The platforms optionally include a cell from a naturally occurring cell line, a cell obtained from differentiating a stem cell/iPS cell taken from an individual with a rare disease, and/or a recombinant cell.
In some alternatives, the rare diseases are associated with one or more biomarkers. If the rare disease is associated with a biomarker, the biomarker is utilized to determine if a treatment for a rare disease is successful, the systemic effects of a treatment, or the dose response of a treatment.

Methods of Identifying Drug and/or Nutraceutical Candidates
The methods disclosed herein identify drug and/or nutraceutical candidates for normalizing, or partially normalizing, a rare-disease associated with an optically-visible cell phenotype. The drug/nutraceutical library includes known drugs, metabolites of known drugs, and/or nutraceuticals. Examples of cell phenotypes that are, or in the alternative are made optically-visible, include cell morphology, nuclear morphology, morphology of the plasma membrane, the morphology of any cytosolic organelle. Where the cell phenotype is not naturally optically-visible, the phenotype is rendered optically-visible due to the use of an optically-visible dye/label (e.g., a fluorescent dye). Individuals that will benefit from these methods and methods are symptomatic (including those with limited symptoms), or asymptomatic.
The methods comprise identifying a rare disease cell with an optically-visible cell phenotype, and visualizing the response of a cell having an optically-visible rare-disease cell phenotype to a drug or nutraceutical from the drug/nutraceutical library to identify drug/nutraceutical hits. The methods are optionally used to establish dose-response curves for the hits. The methods also optionally include genotyping individuals to determine if they would benefit from the methods and methods, for example to determine which strain of a rare disease an individual has, what disease an individual has, if an individual is predisposed to develop a rare disease.
Visualizing the response of a cell having an optically-visible rare-disease cell phenotype to a drug or nutraceutical from the drug/nutraceutical library is optionally done with a microscope with sufficient magnifying power to visualize one cell in a plurality of cells. The images captured by the microscope are optionally stored in electronic memory. The microscope is optionally part of a High Content Screening (HCS) system with automated liquid handling and automated plate handling, image analysis software. The system optionally has software that analyzes degrees of response of the cells to a drug or nutraceutical and dose-response curves.
Any hits identified by these methods are used to create a Rare Disease Specific Drug Library for the rare disease. The methods optionally further include personalizing the Rare Disease Specific Drug Library for each individual with the rare disease, for example some drugs will be eliminated, and/or different drug combinations/dosages will be identified for each individual.
The cells for use with the methods are optionally naturally-occurring cells obtained from a subject with a rare disease cell phenotype, cells derived from stem cells obtained from a subject with a rare disease cell phenotype, or cells derived from iPS cells produced from cells from a subject with a rare disease cell phenotype. The cells are optionally recombinant cells. In some alternatives, the methods include deriving cells from a personalized cell line established from an individual with an optically-visible rare-disease cell phenotype. In other alternatives, the methods include deriving the cell from a general cell line established from a cell obtained from a donor individual with an optically-visible rare-disease cell phenotype. The methods optionally utilize a cell from a naturally occurring cell line, a cell obtained from differentiating a stem cell/iPS cell taken from an individual with a rare disease, and/or a recombinant cell.
In some alternatives, the rare diseases are associated with one or more biomarkers. If the rare disease is associated with a biomarker, the methods optionally include utilizing the biomarker to determine if a treatment for a rare disease is successful, the systemic effects of a treatment, or the dose response of a treatment.

For example, the symptoms of Bechet's Disease include oral mucocutaneous ulcerations, genital ulcerations, erythema nodosum, cutaneous pustular vasculitis, educed visual acuity, reduced color vision, relative afferent pupillary defect, central scotoma, swollen optic disc, macular edema, and/or retrobulbar pain.
Grey Patients
In some embodiments, the patient presents with limited symptoms. In some embodiments, the patient is asymptomatic, e.g., the patient does not present with any symptoms. In some embodiments, patients with limited or no symptoms (“grey patients”) are identified by genotyping. For example, one child in a family presents with a muscular dystrophy. The sibling does not display symptoms of a muscular dystrophy. A genotype screen is performed on the sibling and the sibling is identified as having genetic mutations that may result in development of a muscular dystrophy. The sibling is selected as a “grey” patient and a method or platform disclosed herein is used to identify and optimize a prophylactic treatment protocol for the sibling.

Optically-Visible Phenotypes
Disclosed herein, in certain embodiments, are methods of identifying a drug or nutraceutical candidate for normalizing, or partially normalizing, a rare-disease in a subject in need thereof. Further disclosed herein, in certain embodiments, are rare disease theranostics platforms. In some embodiments, the rare is associated with one or more optically visible cell phenotypes. In some embodiments, the methods and platforms further comprise identifying an optically-visible cell phenotype associated with a rare disease.
As used herein, “phenotype” means the observable characteristics or traits of a rare disease cell, e.g., its morphology, development, biochemical or physiological properties, phenology, behavior.
In some embodiments, the optically-visible rare-disease cell phenotype is selected from cell morphology, nuclear morphology (e.g., chromosomal morphology), morphology of the plasma membrane (e.g., the phospholipid bilayer, channels [e.g., ion channels, receptors], the morphology of any cytosolic organelle [e.g., the rough endoplasmic reticulum (ER), the smooth endoplasmic reticulum, ribosomes, the cytoskeleton (e.g. microfilaments, intermediate filaments and microtubules), the Golgi apparatus, mitochondria, vesicles, lysosomes, peroxisomes, centrosomes, centrioles, vacuoles). In some embodiments, the rare-disease cell phenotype is rendered optically-visible due to the use of an optically-visible dye/label.
In some embodiments, the optically-visible rare-disease cell phenotype is abnormal laminin binding, or abnormal lamin A/C or lamin B binding.
Laminins
Laminins are components of the basal lamina. Laminins influence cell differentiation, migration, and adhesion, as well as phenotype and survival. Laminins are trimeric proteins that intersect to form a cross-like structure that binds to other cell membrane and extracellular matrix molecules. The three shorter arms are particularly good at binding to other laminin molecules, which allows them to form sheets. The long arm is capable of binding to cells, which helps anchor organized tissue cells to the membrane. Laminins are an integral part of the structural scaffolding in almost every tissue of an organism. They are secreted and incorporated into cell-associated extracellular matrices. Laminin is vital for the maintenance and survival of tissues. Defective laminins can cause muscles to form improperly, leading to muscular dystrophies.
Lamins
Nuclear lamins, also known as Class V intermediate filaments, are fibrous proteins providing structural function and transcriptional regulation in the cell nucleus. Nuclear lamins interact with membrane-associated proteins to form the nuclear lamina on the interior of the nuclear envelope They attach to the nuclear envelope membrane via farnesyl anchors and interaction with inner nuclear membrane proteins such as lamin B receptor. Defects in lamins result in abnormal lamin binding, for example abnormal lamin binding to the nuclear envelope. Abnormal lamin binding is associated with nuclear envelope instability in physically stressed tissues such as muscle fibers, bone, skin and connective tissue.
Dyes/Labels
In some embodiments, the optically-visible rare-disease cell phenotype comprises an optically-visible label. In some embodiments, the rare-disease cell phenotype is rendered optically-visible due to the use of an optically-visible label. As used herein, the term “optically visible label” refers to a molecule that facilitates the visualization and/or detection of a targeting molecule disclosed herein. The optically visible label may be directly observable by the eye (e.g., the optically visible label is a fluorescent dye) or it may be visible due to interaction with an intermediate device (e.g., the optically visible label is a radioactive label that is visible following exposure of film or by use of a use of a gamma scintillation camera).
In some embodiments, the optically visible label directly binds (e.g., dyes) a rare disease cell or one or more components of the cell (e.g., the nucleus, or an organelle, a protein, a lipid, or a polysaccharide.
In some embodiments, the optically visible label indirectly binds a rare disease cell or one or more components of the cell (e.g., the nucleus, or an organelle, a protein, a lipid, or a polysaccharide). For example, in some embodiments, the optically visible label is bound to an antibody that binds to a rare disease cell or one or more components of the cell (e.g., the nucleus, or an organelle, a protein, a lipid, or a polysaccharide). In some embodiments, the optically visible label is bound to streptavidin (or avidin) which is bound to biotin, the biotin being bound to an antibody that binds to a rare disease cell or one or more components of the cell (e.g., the nucleus, or an organelle, a protein, a lipid, or a polysaccharide).

Cells
Disclosed herein, in certain embodiments, are methods of identifying a drug or nutraceutical candidate for normalizing, or partially normalizing, an optically-visible rare-disease cell phenotype in a subject in need thereof, comprising (a) contacting a plurality of cells having the optically-visible rare-disease cell phenotype with a drug or nutraceutical from a drug/nutraceutical library, (b) obtaining a magnified image of the plurality of cells following contact with the drug or nutraceutical from the drug/nutraceutical library; and (c) analyzing the magnified images to determine the response of the plurality of cells to the drug or nutraceutical from the drug/nutraceutical library. Further disclosed herein, in certain embodiments, are rare disease theranostics platforms, comprising: (a) a cell-phenotype image-enhancing instrument; (b) a drug/nutraceutical library; and (c) a computer-implemented system for analyzing a response of an optically-visible rare-disease cell phenotype to a drug or nutraceutical from the drug/nutraceutical library.
In some embodiments, a cell having the optically-visible rare-disease cell phenotype is derived from a biological fluid, e.g., blood. In some embodiments, a cell having the optically-visible rare-disease cell phenotype is derived from a biopsy (e.g., a skin biopsy, a muscle biopsy, a bone marrow biopsy, a liver biopsy, a gastrointestinal biopsy, a lung biopsy, a nervous system biopsy, a lymph node biopsy). Non-limiting examples of cells that may have an optically-visible rare-disease cell phenotype include blood cells (erythrocytes), immune cells (e.g., monocytes, macrophages, neutrophils, eosinophils, basophils, mast cells, T cells, B cells, NK cells), myocytes (e.g., skeletal muscle cells (e.g., red skeletal muscle cells or white skeletal muscle cells), myocardiocytes), fibroblasts, osteoblasts, osteocytes, adipocytes (e.g., unilocular cells, multilocular cells), hepatocytes, glial cells (e.g., astrocytes, oligodendrocytes, Schwann cells), neurons, epidermal cells (e.g., keratinocytes, melanocytes, Langerhans cells, Merkel cells).
In some embodiments, the cells are naturally-occurring cells (e.g., fibroblasts) obtained from a subject with a rare disease cell phenotype. In some embodiments, the cells are derived (e.g., differentiated) from stem cells obtained from a subject with a rare disease cell phenotype. In some embodiments, the cells are derived (e.g., differentiated) from iPS cells (induced pluripotent stem cells) produced from cells from a subject with a rare disease cell phenotype. In some embodiments, the cells are recombinant cells (e.g., they comprise a non-naturally occurring maker such as an antibiotic resistance gene or a fluorescent marker).
Production of Cells and Cell Lines
In some embodiments, the platforms and methods disclosed herein further comprise establishing a cell line comprising a plurality of cells with an optically-visible rare-disease cell phenotype. In some embodiments, the cell line comprising a plurality of cells with an optically-visible rare-disease cell phenotype is established from a stem cell line or iPS cell line obtained from an individual with an optically-visible rare disease cell phenotype. Any suitable method of establishing and maintaining cell lines may be used with the methods and platforms disclosed herein.
In some embodiments, the cell line is a differentiated cell line (e.g., a fibroblast cell line). In some embodiments, cells are isolated from a subject with a rare-disease cell phenotype. In some embodiments, the cells are maintained in culture by any suitable method using any suitable media. For example, fibroblasts may be grown in Dulbecco's Modified Eagle Medium supplemented with 10% Fetal Bovine Serum, 2 mM L-glutamine, and 0.1 mM 2-mercaptoethanol at 37° C. with 5% CO₂. In some embodiments, the cells are passaged until senescence (e.g., until the Hayflick limit is reached).
In some embodiments, a stem cell line or iPS cell line is used to avoid senescence of a cell line of differentiated cells with an optically-visible rare-disease cell phenotype. As used herein, “senescence” means the phenomenon by which normal cells lose the ability to divide. In differentiated cell, senescence normally occurs after about 50 cell divisions in vitro. The “Hayflick limit” refers to the maximum number of passages a cell may undergo before senescence.
As used herein, a “stem cell” is a cell that is capable of self-renewal and is potent (e.g., omnipotent, pluripotent, multipotent, oligopotent). The stem cell may be an embryonic stem cell or an adult stem cell. The stem cell may be a hematopoietic stem cell, a skeletal stem cell, a neural stem cell, or a mesenchymal stem cell.
In some embodiments, stem cells are isolated from a subject with a rare-disease cell phenotype. In some embodiments, the stem cells are maintained in culture by any suitable method using any suitable media. In some embodiments, the stem cells are maintained undifferentiated in culture by any suitable method using any suitable media. For example, the stem cells are grown on a 3D hydrogel or on plates with a “nano-patterned” surface. Where the stem cells are mesenchymal stem cells, the cells may be grown on CELLstart™ (Invitrogen) in MesenPRO RS™ Medium (Invitrogen) in order to maintain potency.
As used herein, an “iPS cell” is a pluripotent cell artificially derived from a non-pluripotent cell with an optically visible rare disease cell phenotype. The iPS cell is derived by inducing expression of specific genes that dedifferentiate the non-pluripotent cell and/or contacting the non-pluripotent cell with one or more small molecules that dedifferentiate the non-pluripotent cell.
Any suitable method is used to produce an iPS. Generally, an iPS is produced by isolating cells (e.g., fibroblasts) from a donor (e.g., an individual with a rare disease of interest), transfecting genes that induce dedifferentiation (e.g., Oct-3/4 (Pou5fl), Sox2, c-MYC, Klf4, Nanog, and/or LIN28) into the cells (e.g., by viral vectors) and/or contacting the cells with small molecules that mimic transcription factors, and harvesting and culturing the transfected cells using stem cell culture protocols.
iPS cells for use with the methods and platforms disclosed herein may have any of the following features:
Morphology: The iPS cells may have a round shape, large nucleolus and scant cytoplasm. Colonies of iPS cells may form sharp-edged, flat, tightly-packed colonies.
Growth properties: The iPS cells may be mitotically active, actively self-renewing, proliferating, and divide at a rate equal to stem cells.
Stem cell markers: The iPS cells may express SSEA-3, SSEA-4, TRA-1-60, TRA-1-81, TRA-2-49/6E, and Nanog.
Stem Cell Genes: The iPS cells may express OCT-3/4, SOX2, NANOG, GDF3, REX1, FGF4, ESG1, DPPA2, DPPA4, and hTERT.
Telomerase activity: The iPS cells may demonstrate high telomerase activity and express hTERT (human telomerase reverse transcriptase).
Pluripotency: The iPS cells may be capable of differentiation into fully differentiated tissues.
In some embodiments, the cells are recombinant cells. In some embodiments, the cells are transfected with a marker gene (e.g., an antibiotic resistance gene, or a fluorescence gene such as a gene encoding GFP) using any suitable method. For example, a fibroblast cell line is grown in Dulbecco's Modified Eagle Medium supplemented with 10% Fetal Bovine Serum, 2 mM L-glutamine, and 0.1 mM 2-mercaptoethanol at 37° C. with 5% CO₂ to 60% confluency. The DNA encoding the antibiotic resistance gene is precipitated in ethanol and resuspended in sterile water or TE buffer to a final concentration of 0.2-1 mg/ml. The resuspended DNA is mixed with cell growth medium and the transfection reagent (e.g., TransFast™ Reagent) to form transfection medium. The growth medium is removed from the fibroblast cell culture and the transfection medium is added to the fibroblasts cells.
Personalized Cell Lines
In some embodiments, a personalized cell line is established for a donor individual with an optically-visible rare-disease cell phenotype, wherein the personalized cell line is used to identify a drug or nutraceutical candidate for normalizing, or partially normalizing, the optically-visible rare-disease cell phenotype in that donor individual.
In some embodiments, a personalized stem cell line is established from a stem cell obtained from an individual with an optically-visible rare-disease cell phenotype. In some embodiments, a plurality of stem cells from the stem cell line is differentiated into a plurality of differentiated cells with the optically-visible rare-disease cell phenotype. In some embodiments, the differentiated cells with the optically-visible rare-disease cell phenotype are used to establish a cell line to identify a drug or nutraceutical candidate for normalizing, or partially normalizing, the optically-visible rare-disease cell phenotype in the individual with the optically-visible rare-disease cell phenotype.
In some embodiments, a personalized iPS cell line is established from a cell obtained from an individual with an optically-visible rare-disease cell phenotype. In some embodiments, the platforms and methods disclosed herein further comprise (a) dedifferentiating a cell obtained from the individual into an iPS cell (e.g., to establish a cell line), and then (b) differentiating the iPS cell into a cell with the optically-visible rare-disease cell phenotype (e.g., for use to identify a drug or nutraceutical candidate for normalizing, or partially normalizing, the optically-visible rare-disease cell phenotype in the individual).
General Cell Lines
In some embodiments, a general cell line is established from a cell obtained from a donor individual with an optically-visible rare-disease cell phenotype. In some embodiments, a general cell line is used to identify a drug or nutraceutical candidate for normalizing, or partially normalizing, the optically-visible rare-disease cell phenotype in the donor individual or any individual with the optically-visible rare-disease cell phenotype. In some embodiments, the cell line corresponds to a particular subtype (e.g., gradation) of the optically-visible rare-disease cell phenotype. For example, a general cell line may be established for an optically-visible rare-disease cell phenotype; or, a general cell line may be established for (a) a severe form of the optically-visible rare-disease cell phenotype, (b) a moderate form of the optically-visible rare-disease cell phenotype, and/or (c) an undetectable form of the optically-visible rare-disease cell phenotype.
In some embodiments, a general stem cell line is established from a stem cell obtained from a donor individual with an optically-visible rare-disease cell phenotype. In some embodiments, a plurality of stem cells from the stem cell line is differentiated into a plurality of differentiated cells with the optically-visible rare-disease cell phenotype. In some embodiments, the differentiated cells with the optically-visible rare-disease cell phenotype are used to establish a cell line to identify a drug or nutraceutical candidate for normalizing, or partially normalizing, the optically-visible rare-disease cell phenotype in the donor individual or any individual with the optically-visible rare-disease cell phenotype.
In some embodiments, a general iPS cell line is established from a cell obtained from a donor individual with an optically-visible rare-disease cell phenotype. In some embodiments, the platforms and methods disclosed herein further comprise (a) dedifferentiating a cell obtained from the donor individual into an iPS cell (e.g., to establish a cell line), and then (b) differentiating the iPS cell into a cell with the optically-visible rare-disease cell phenotype (e.g., for use to identify a drug or nutraceutical candidate for normalizing, or partially normalizing, the optically-visible rare-disease cell phenotype in the donor individual or in any individual with the optically-visible rare-disease cell phenotype).
Rare-Disease Specific Drug Libraries
Disclosed herein, in certain embodiments, are rare disease specific drug libraries identified by the methods and platforms disclosed herein. In some embodiments, a general rare disease specific drug library is identified using a cell line obtained from an individual with the rare disease cell phenotype, e.g., a general cell line. In some embodiments, the general rare disease specific drug library is screened with a personalized cell line to identify a personalized rare disease specific drug sub-library that is specific to an individual. In some embodiments, the general rare disease specific drug library is screened with a personalized cell line to optimize the dosages of the drugs in the generalized rare disease specific drug library for an individual. For example, a first individual presents with a rare disease. Cells are obtained from the individual and used to establish a rare disease general cell line. The general cell line is used to identify a general rare disease specific drug library with 6 drugs. A second individual presents with the rare disease. Cells are obtained from the individual and used to establish a rare disease personalized cell line. The general rare disease specific drug library is screened with the personalized cell line and a personalized rare disease specific drug sub-library with 4 drugs is identified.
EXAMPLES
Example 1
Laminin Binding Assay to Identify Compounds that Normalize Laminin Binding Deficiency in Fibroblasts from a Muscular Dystrophy Patient
Fibroblasts obtained from a muscular dystrophy patient were seeded at 3000 cells per well in 384-well plates and treated in duplicate at 10 μm with individual compounds from the drug/nutraceutical library. After 48 hours in culture conditions, the cells were exposed to serum free media containing 0.1% BSA and 10 ug/ml laminin from Engelbreth-Holm-Swarm murine sarcoma basement membrane for a period of 2 hours. Cells were then fixed with 4% paraformaldehyde and stained with DAPI and a laminin-specific antibody, followed by a fluorescently labeled secondary antibody directed against the laminin specific antibody. The plates were then scanned using an Opera high content confocal microscopy screening system (PerkinElmer) at 20× magnification with separate fluorescent exposures, utilizing a UV light source and a 561 nm laser.
Image analysis was performed to quantify levels of laminin staining using a customized algorithm written with Acapella software (Perkin Elmer). The cytoplasm was defined using DAPI staining as a mask, and the average cytoplasmic intensity of fluorescence per cell was calculated on the basis of at least six random fields captured per well.
A compound in the drug/nutraceutical library was considered to normalize the level of fibroblast laminin binding if the compound scored at least 20% activity compared with controls. Fibroblasts from a healthy individual, or from patient cells treated with Trichostatin A at 2 uM were used as positive controls.
Trichostatin A and SAHA were identified as hits in the assay. Trichostatin A, SAHA, and Givinostat (another HDAC inhibitor in the same class as Trichostatin A and SAHA) were further tested in an eight-point dose-response assay (at a range of 20-0.02 μm, at three fold dilutions) in triplicate.
Example 2
Use of the High-Content Screen to Identify Drugs/Nutraceuticals that Normalize an Optically Visible Rare Disease Cell Phenotype
Fibroblasts are obtained from a patient presenting with Rare Disease. The fibroblasts are placed in a 384-well plate for 48 hours, as described in Example 1.
Each well of the plate is then treated with a compound from a known drug or nutraceutical library. The fibroblasts are then scanned to search for changes in the optically visible rare disease cell phenotype. Positive compounds are then further tested to eliminate false positives. Positive compounds are also further tested to optimize concentrations and test for efficacious drug combinations. Positive hits are identified using a computer-based algorithm.
Compounds found to be effective for normalizing the optically visible Rare Disease phenotype are classified as Rare Disease Library 1 and administered to the patient in order to treat symptoms of the rare disease.
Example 3
Testing Fibroblasts from a Second Patient with a Rare Disease with Drugs/Nutraceuticals Previously Found to Normalize Cells from a Patient with the Same Rare Disease
Rare Disease Library 1 (a “Rare Disease Specific Drug Library”) is identified as in Example 2.
A second patient presents with Rare Disease. Fibroblasts are taken from the patient in order to identify a personalized rare disease specific sub-library specific to the second patient. The fibroblasts taken from the second patient are used to establish a personalized cell line and are plated in a 384-well plate, as described in Example 1.
Rare Disease Library 1 is screened against the second patient's personalized cell line. Positive hits are identified using a computer-based algorithm.
The positive hits are further tested with the personalized cell line of the second patient in order to eliminate false positives. Compounds found to be effective for normalizing the optically visible Rare Disease phenotype of the second individual are classified as Rare Disease Library 1a. Positive compounds are further tested to optimize concentrations and test for efficacious drug combinations.
Hits found to be effective for normalizing the optically visible rare disease phenotype in the personalized cell line are administered to the second patient in order to treat symptoms of the rare disease.
Example 4
Use of the High-Content Screen to Identify Drugs/Nutraceuticals that Normalize an Optically Visible Rare Disease Phenotype in Cells from a “Grey Patient”
A “grey patient” has been genotyped as carrying a gene mutation which leads to the Rare Disease, although the patient does not present with any symptoms of Rare Disease.
Cells from the “grey patient” are placed in a 384-well plate for 48 hours, as described in Example 1. Rare Disease Library 1 (a “Rare Disease Specific Drug Library”) is screened against the “grey patient's” personalized cell line. Positive hits are identified using a computer-based algorithm.
The positive hits are further tested with the personalized cell line of the second patient in order to eliminate false positives. Compounds found to be effective for normalizing the optically visible Rare Disease phenotype of the second individual are classified as Rare Disease Library 1b. Positive compounds are further tested to optimize concentrations and test for efficacious drug combinations.
Hits found to be effective for normalizing the optically visible rare disease phenotype in the personalized cell line are administered to the second patient in order to treat symptoms of the rare disease. See more
