Association between MTHFR polymorphism (C677T) with nonfamilial colorectal cancer
The enzyme 5,10-methylene-tetrahydrofolate reductase (MTHFR) is linked to DNA methylation, synthesis, and repair. C677T is one of the most important polymorphisms in the MTHFR gene. The single nucleotide polymorphism C677T ...
Association between the 1793G>A MTHFR polymorphism and sporadic colorectal cancer in Iran
Background: It has been proposed that folate and polymorphisms of the enzyme methylenetetrahydrofolate reductase (MTHFR), which regulates influx of folate for methylation reactions for DNA synthesis and repair, are involved ...
Evaluation of global genome methylation in gastritis lesion and its correlation with clinicopatological findings
Global genome hypomethylation as an epigenetic phenomenon may induce (pre)neoplastic transformation through inducing chromosomal and genomic instability and activating oncogenes. Global genome hypomethylation has a fundamental ...
Impact of EXO1 polymorphism in susceptibility to colorectal cancer
Background and Aim: One candidate gene for colorectal cancer (CRC) susceptibility is exonuclease 1 (EXO1). It is a member of RAD2 nuclease family, which plays a major role in mismatch repair, DNA replication, and recombination. ...
Profile and frequency of p53 Gene alterations in gastritis lesions from Iran
Background: It has been frequently shown that p53 alterations have an important role in the development of gastric cancers but there is no data on p53 alteration in gastric cancer and its precancerous lesions from Iran ...
Seroepidemiology of hepatitis A and E virus infections in Tehran, Iran: A population based study
Hepatitis A virus (HAV) and hepatitis E virus (HEV) are enteric hepatotropic viruses and their prevalence is related to the sanitary conditions of the region under investigation. There are only a few studies on the ...
