Background: Methotrexate (MTX) is an anti-folate drug with anti-proliferative and anti-inflammatory effects. MTX proved to be the most highly effective, fast-acting disease modifying anti-rheumatic (DMARD), being widely used for treatment of rheumatoid arthritis (RA) (1). Objectives: This review aims describe main genetic variants identified concerning proteins that play a role in methotrexate’...
The ubiquitously expressed reduced folate carrier (RFC) is the major transport system for folate cofactors in mammalian cells and tissues. Previous considerations of RFC structure and mechanism were based on the notion that RFC monomers were sufficient to mediate transport of folate and antifolate substrates. The present study examines the possibility that human RFC (hRFC) exists as higher orde...
Folate plays an essential role in one-carbon metabolism, and a relationship exists between methyl group metabolism and pancreatic exocrine function. Little, however, is known about the mechanism(s) and regulation of folate uptake by pancreatic acinar cells and the effect of chronic alcohol use on the process. We addressed these issues using the rat-derived pancreatic acinar cell line AR42J and ...
Proton-coupled folate transporter/heme carrier protein 1 (PCFT/HCP1) has recently been identified as a transporter that mediates the translocation of folates across the cellular membrane by a proton-coupled mechanism and suggested to be the possible molecular entity of the carrier-mediated intestinal folate transport system. To further clarify its role in intestinal folate transport, we examine...
arsenic is an important environmental toxicant which is usually found in drinking water in inorganic form. the hypothesis tested in this investigation is; arsenic exposure causes neural tube defects (ntds) andthese defects of the central nervous system are more likely related to folate deficiency during fetal life. in this study, sodium arsenate was administered via intraperitoneal route at a r...
