Background: Red Blood Cell's (RBC)’s folate may be related to decreased risk of colorectal adenoma. Methylenetetrahydrofolate reductase (MTHFR) is a key regulatory enzyme in folate metabolism. The MTHFR C677T polymorphism is located in the Exon 4 region and is associated with the change of folate level. This study evaluated the associations between RBC’s Folate levels and colorectal adenoma ris...
background : increased level of serum homocysteine is one of the risk factor of atherosclerosis. its production related in some sulfur amino acids such as methionine. some important cofactors that are involved in metabolic pathways of this amino acid are folate and vitamin b12. we have assessed the status of methionine, folic acid, and vitamin b12 in some coronary atherosclerotic male patients....
Nanoparticles of Poly(L-glutamic acid) (PG) conjugated to the anticancer drug paclitaxel and targeted moiety folic acid (FA) were synthesized and characterized in vitro. The nanoparticles were designed to take advantage of FA targeting to folate receptor (FR) positive cancer cells. The chemical composition of the conjugate was characterized by H-NMR, FTIR and UV/vis spectroscopy. The selective ...
The proton-coupled folate transporter (PCFT) provides an essential uptake route for the vitamin folic acid (B9) in mammals. In addition, it is currently of high interest for targeting chemotherapeutic agents to tumors due to the increased folic acid requirement of rapidly dividing tumor cells as well as the upregulated PCFT expression in several tumors. To understand its function, determination...
Lymphatic filariasis, commonly called elephantiasis, poses a burden of estimated level of 5.09 million disability adjusted life year. Limitations of its sole drug, diethylcarbamazine (DEC) drive exploration of effective filarial target. A few plant extracts having polyphenolic ingredients and some synthetic compounds possess potential dihydrofolate reductase (DHFR) inhibitory effect. Here, we p...
BACKGROUND Nanoparticulate drug delivery systems have attracted significant attention in the field of cancer nanotechnology. This study determines the effect of folate-based Fe2O3 nanoparticles. This study aimed to decorate nanoparticles with folate (FA), a molecular ligand for 'active' targeting of cancerous cells and the application of modified-nanoparticles in cancer treatment. MATERIALS A...
background: the role of nutrition in the progression of multiple sclerosis (ms) and related complications such as fatigue has been reported by several studies. the aim of this study is the assessment of nutritional status and its relationship with fatigue in multiple sclerosis patients. methods: this is a cross-sectional study, in which 101 relapsing-remitting ms patie...
PEGylated and non-PEGylated ORMOSIL nanoparticles prepared by microemulsion condensation of vinyltriethoxy-silane (VTES) were investigated in detail for their micro-structure and ability to deliver photoactive agents. With respect to pure silica nanoparticles, organic modification substantially changes the microstructure and the surface properties. This in turn leads to a modulation of both the...
The proton-coupled folate transporter (PCFT; SLC46A1) is a proton-folate symporter that is abundantly expressed in solid tumors and normal tissues, such as duodenum. The acidic pH optimum for PCFT is relevant to intestinal absorption of folates and could afford a means of selectively targeting tumors with novel cytotoxic antifolates. PCFT is a member of the major facilitator superfamily of tran...
A modular p-phosphonated calix[4]arene vesicle (PCV) loaded with paclitaxel (PTX) and conjugated with folic acid as a cancer targeting ligand has been prepared using a thin film-sonication method. It has a pH-responsive capacity to trigger the release of the encapsulated PTX payload under mildly acidic conditions. PTX-loaded PCV conjugated with alkyne-modified PEG-folic acid ligands prepared vi...
