Objective(s): Glutamate is the most widespread neurotransmitter in the central nervous system and has several functions as a neuromodulator in the brain although in pathological conditions like ischemia it is excessively released causing cell death. Under physiological conditions, glutamate is rapidly scavenged from the synaptic cleft by excitatory amino-acid transport...

Metabolic engineering of microbial hosts for the production heterologous metabolites and biochemicals is an enabling technology to generate meaningful quantities desired products that may be otherwise difficult produce by traditional means. Heterologous metabolite can restricted accumulation toxic within cell. Efflux transport proteins (transporters) provide a potential solution facilitate expo...

Objective(s):Transporters have an important role in pharmacokinetics of drugs. Inhibition or induction of drug transporters activity can affect drug absorption, safety, and efficacy. P-glycoprotein (P-gp) is the most important membrane transporter that is responsible for active efflux of drugs. It is important to understand which drugs are substrates, inhibitors, or inducers of P-gp to minimize...

Objective(s): Crocetin, one of the main substances of saffron extract, has anti-cancer effects. Drug resistance proteins (e.g. MRP1 and MRP2) are important reasons for the failure of cancer therapy. We intended to investigate the efficacy of crocetin on MRP1 and MRP2 activity in human ovarian cisplatin-resistant carcinoma cell line (A2780-RCIS).Materials and Methods: The cytotoxic effect of cro...

cardiovascular disease (cvd) is the leading cause of death and disability in developed countries. atherosclerosis is the major cause of cvd, accounting for about half of the attributed deaths. cholesterol homeostasis is one of the most important factors in atherosclerosis. atp-binding cassette transporters cholesterol. omega (ω) 3 fatty acids are important ligands for regulation of abc transpor...

As a product of protein catabolism, urea is moved around the body and through kidneys for excretion. Although there experimental evidence concentrative transporters, these have not been defined at molecular level. The SLC14 family are facilitative allowing movement down its concentration gradient. Multiple splice variants transporters identified; UT-A in particular, cell-specific expression wit...

Hydroponically grown ten grape genotypes (Vitis vinifera L.) were treated with different concentrations of NaCl. Chawga genotype accumulated K+ in its root and shoot even at high salinity. The correlation between Na+ and K+ concentrations in root and lamina of all genotypes was negative (P

Molecular information of K+ accumulation in grapes is strongly required. Under salinity condition potassium transporters are inhibited by Na+. The aim of this study was to investigate the effects of salinity on the expression of K+ transporter genes in grape. Based on the previous screening study on 18 grape genotypes, ‘H6’ and ‘Gharashani’ (tolerant) and ‘Shirazi’ and ‘GhezelUzum’ (sensitive) ...

Anti-retroviral (ARV) -based microbicides are one of the strategies pursued to prevent HIV-1 transmission. Delivery of ARV drugs to subepithelial CD4+ T cells at concentrations for protection is likely determined by drug transporters expressed in the cervicovaginal epithelium. To define the role of drug transporters in mucosal disposition of topically applied ARV-based microbicides, these must ...
