Hydroxyproline is one of the most prevalent amino acids in animal proteins. It is not a genetically encoded amino acid, but, rather, it is produced by the post-translational modification of proline in collagen, and a few other proteins, by prolyl hydroxylase enzymes. Although this post-translational modification occurs in a limited number of protei...
The recent advances in nucleic acid therapeutics demonstrate the potential to treat hereditary neurological disorders by targeting their causative genes. Spinal and bulbar muscular atrophy (SBMA) is an X-linked and adult-onset neurodegenerative disorder caused by the expansion of trinucleotide cytosine-adenine-guanine repeats, which encodes a polyg...
ABSTRACTInvestigating the biosynthesis and function of newly identified intronic small interference RNA in Caenorhabditis elegansSmall interfering RNA (siRNA) are critical regulators of gene expression in many animals. In the model organism C. elegans, our lab found that disruption of the siRNA machinery results in an inability to sense and adapt t...

Cardiac thyrotropin-releasing hormone (TRH) is a tripeptide with still unknown functions. We demonstrated that the left ventricle (LV) TRH system is hyperactivated in spontaneously hypertensive rats and its inhibition prevented cardiac hypertrophy and fibrosis. Therefore, we evaluated whether in vivo cardiac TRH inhibition could improve myocardial ...

Negeviruses are a proposed group of insect-specific viruses that can be separated into two distinct phylogenetic clades, Nelorpivirus and Sandewavirus. Negeviruses are well-known for their wide geographic distribution and broad host range among hematophagous insects. In this study, the full genomes of two novel negeviruses from each of these clades...

Background: RNA interference (RNAi) therapy has tremendous potential in treating diseases that are characterized by overexpression of genes. However, the biggest challenge to utilize the therapy is to engineer delivery systems that can efficiently transport small interfering RNA (siRNA) to appropriate target sites. Our objective in this study was t...

Rosacea is a prevalent skin condition dependent on the individual genetic profile. The current pharmacological management of this condition is mostly based on small molecule drugs predominately effective in ameliorating the inflammatory condition. Emerging molecular approaches could present an opportunity for managing rosacea conditions at transcri...

Cationic niosomes have become important non-viral vehicles for transporting a good number of small drug molecules and macromolecules. Growing interest shown by these colloidal nanoparticles in therapy is determined by their structural similarities to liposomes. Cationic niosomes are usually obtained from the self-assembly of non-ionic surfactant mo...

Snail-1 known as one of the important transcription factor is a mediator of survival and cell migration, and expression is raised in numerous cancer types. Snail-1 gene may show a role in recurrence of several cancers including bladder cancer by down-regulating E-cadherin, inducing an epithelial to mesenchymal transition (EMT) and its related micro...

Although radiotherapy remains the most powerful as well as the primary treatment modality for nasopharyngeal carcinoma (NPC), approximately 20% of NPC patients still have local recurrence. Carbonic anhydrase IX (CAIX)-related signaling pathways that mediate radioresistance have been found in various kinds of cancer. However, the role of CAIX in NPC...
