Gastric cancer is one of the most common malignancies worldwide and it is a fourth leading cause of cancer-related death. Carcinogenesis is a multistage disease process specified by the gradual procurement of mutations and epigenetic alterations in the expression of different genes, which finally lead to the occurrence of a malignancy. These genes ...

It is well established that expression of multi-drug resistance (MDR) proteins (MDR1, BCRP, MDR3, MRP1, and LRP) in leukemic blasts correlates with acute myeloid leukemia (AML) patients' clinical response. Assuming that leukemic stem cells (LSC) are resistant to chemotherapy and responsible for relapse, it might be clinically relevant to evaluate t...

The ATP-binding cassette (ABC) transporters are members of a protein superfamily that are known to translocate various substrates across membranes, including metabolic products, lipids and sterols, and xenobiotic drugs. Multidrug resistance proteins (MRPs) belong to the subfamily C in the ABC transporter superfamily. MRPs have been implicated in me...
On account of its extreme intrinsic resistance to apoptosis and of its strong ability to become chemoresistant after a primary response to drugs, malignant melanoma (MM) is still a therapeutic challenge. We previously showed that glutathione S-transferase mu 1 (GSTM1) acts in synergy with multidrug resistance protein 1 (MRP1) to protect GSTM1-trans...
Candidate: Deirdre Thajam, University of Manchester. Degree: PhD, May 2013Title: The Role of Multidrug Resistance Proteins in Determining Fetal Susceptibility to Drugs of Misuse.Background- Negative outcomes from fetal exposure to maternal dug use include Neonatal Abstinence Syndrome (NAS) and altered development, the unpredictability of which sugg...
Previous studies showed that altered gravity conditions lead to different adaptation responses in various cells, like changes in proliferation, morphology or signal transduction. These changes are forwarded through intracelllular signaling cascades which are, amongst others, mediated by the important second messengers cGMP and cAMP. On the basis of...

Macrophages represent major cellular targets of various drugs, especially antibiotics and anti-viral drugs. Factors that may govern intracellular accumulation of drugs in these cells, especially those related to activity of drug transporters, are consequently likely important to consider. The present study was therefore designed to extensively char...

Pancreatic cancer ranks among the tumors most resistant to chemotherapy. Such chemoresistance of tumors can be mediated by various cellular mechanisms including dysregulated apoptosis or ineffective drug concentration at the intracellular target sites. In this review, we highlight recent advances in experimental chemotherapy underlining the role of...

In the last decade, there has been substantial progress in understanding vectorial ligand transport through rodent and human choroid plexus (CP), the locus of the blood-CSF interface. In this Review, we enumerate the experimental data required to establish vectorial transport through CP and describe transporters involved in vectorial transport acro...

Resistance to chloroquine (CQ) in Plasmodium falciparum has a major impact on malaria control worldwide. To gain insight into early parasite stress response, mRNA expression profiles were determined for a set of 10 antioxidant defence genes in synchronized CQ-sensitive (3D7) and CQ-resistant (Dd2) clones under transient IC50 CQ-exposure (Dd2, 200 n...
