The proton-coupled folate transporter (PCFT, SLC46A1) mediates folate transport across the apical brush-border membrane of the proximal small intestine and the basolateral membrane of choroid plexus ependymal cells. Two loss-of-function mutations in PCFT, which are the basis for hereditary folate malabsorption, have been identified within the fourth transmembrane domain (TMD4) in subjects with ...
Response surface methodology (RSM) was used to optimize the process of preparing bovine serum albumin (BSA) nanoparticles by desolvation, then the resulting BSA nanoparticles (BSANPs) were conjugated with folate to produce a drug carrier system that can specifically target tumors. The anticancer drug, vinblastine sulfate (VBLS), was loaded to this tumor-specific drug carrier system for the purp...
PURPOSE The aim of this study is to investigate the effect of genetic variations and the expression of the reduced folate carrier (RFC) and dihydrofolate reductase (DHFR) on the drug sensitivity to methotrexate (MTX) in different cancer cell lines. MATERIALS AND METHODS We examined the six human cancer cell lines (MCF-7, AGS, A549, NCI-H23, HCT-116 and Saos-2). The cytotoxicity of MTX was mea...
During meiotic recombination, induced double-strand breaks (DSBs) are processed into crossovers (COs) and non-COs (NCO); the former are required for proper chromosome segregation and fertility. DNA synthesis is essential in current models of meiotic recombination pathways and includes only leading strand DNA synthesis, but few genes crucial for DNA synthesis have been tested genetically for the...
The major cellular pathway for uptake of the vitamin folic acid, including its absorption in the intestine, is via a plasma membrane carrier system, the reduced folate carrier (RFC). Very little is known about the mechanisms that control intracellular trafficking and plasma membrane targeting of RFC. To begin addressing these issues, we used Xenopus oocyte as a model system and examined whether...
