BACKGROUND AND AIMS There is evidence that the polymorphisms of the genes involved in folate metabolism may be associated with higher risk of Down syndrome (DS) pregnancy. The aim of the present study was to investigate the effect of A80G polymorphism in reduced folate carrier 1 (RFC1) gene on the maternal risk for DS. METHODS In our study, twenty-two DS mothers and forty-two mothers who had ...

We found that basal-like breast cancer (BLBC) cells use Cdc42 to inhibit function of the redox/Fyn/c-Cbl (RFC) pathway, which normally functions to convert small increases in oxidative status into enhanced degradation of c-Cbl target proteins. Restoration of RFC pathway function by genetic or pharmacological Cdc42 inhibition enabled harnessing of pro-oxidant effects of low µM tamoxifen (TMX) co...

Introduction: Cleft lip/palate is one of the most common congenital defects and is supposed to have multifactorial etiology, including a complex interaction between genetics and environment. Reduced folate carrier 1 (RFC1) gene takes part in folate transportation within the cells. In this study, the association of A80G polymorphism in the RFC1 gene with the non-syndromic cleft lip/palate (nsCL/...

Colorectal cancer is one of the most common malignancies in developed countries and chemotherapy is the standard treatment option for advanced colorectal cancer. Identification of biomarkers for predicting response to uracil/ftorafur plus leucovorin (UFT/LV) chemotherapy is an important issue in colorectal cancer treatment. Organic anion transporter 2 (OAT2) and reduced folate carrier 1 (RFC1) ...

We recently identified a cDNA clone from mouse small intestine, which appears to be involved in folate transport when expressed in Xenopus oocytes. The open reading frame of this clone is identical to that of the reduced folate carrier (RFC) (K. H. Dixon, B. C. Lanpher, J. Chiu, K. Kelley, and K. H. Cowan. J. Biol. Chem. 269: 17-20, 1994). The characteristics of this cDNA clone [previously refe...

E-mail: [email protected] Movement disorders (MD) in patients with multiple sclerosis (MS) has been few reported. The most common MD associated with MS are tremor and dystonia, but parkinsonism, myoclonus, chorea, ballism, paroxysmal dyskinesias and h...

Although the reduced folate carrier RFC1 and the thiamine transporters THTR-1 and THTR-2 share approximately 40% of their identity in protein sequence, RFC1 does not transport thiamine and THTR-1 and THTR-2 do not transport folates. In the present study, we demonstrate that transport of thiamine monophosphate (TMP), an important thiamine metabolite present in plasma and cerebrospinal fluid, is ...

Several reports demonstrated that maternal lipopolysaccharide (LPS) exposure at middle gestational stage caused neural tube defects (NTDs). This study investigated the effects of supplementation with vitamin D3 (VitD3) during pregnancy on LPS-induced NTDs. Pregnant mice except controls were ip injected with LPS (25 μg/kg) daily from gestational day (GD)8 to GD12. In LPS+VitD3 group, pregnant mi...
