normal 0 false false false en-us x-none fa microsoftinternetexplorer4 aim : the purpose of this study was to determine the relationship of rs4444903 (egf+61a/g) snp genotype with colorectal cancer and tumor stage in an iranian population. background : epidermal growth factor ( egf ) is one of the important proteins that determine survival of cells. egf binds to its receptor on the cell surface ...

One of the essential protection mechanisms of immune system is Treg cells which play an important role in maintenance ofimmune homeostasis. However, they may also inhibit immune functions against tumor cells. It has been reported that Treg cellsare increased in patients suffering from different types of cancer. Increased number of Treg cells has been shown in tumor lymphnodes, peripheral blood,...

colorectal cancer (crc) is the second leading cause of cancer death. progress has been made in the development of chemotherapy for advanced crc. targeted therapies against vegf or egfr are now commonly used. however, many cases show that tolerance develops to such treatments; therefore, new strategies are required to replace or complement current therapies. nuclear factor-?b (nf-?b) transcripti...

aim: the purpose of this study was to evaluate the influence of intronic polymorphism of the smad7 (mothers against decantaplegic homolog 7) gene (rs2337104) on the risk of colorectal cancer (crc) and clinicopathological features in an iranian population background : smad7 has been identified as an antagonist of transforming growth factor beta (tgf-b)-mediating fibrosis, carcinogenesis, and inf...

Background & Aims: Many studies have demonstrated that Vitamin D has an important role in cell growth and proliferation and vitamin D receptor polymorphism has significant relationship with colorectal cancer (CRC). The aim of this study was to assess the incidence of VDR rs 2238136 polymorphism in Iranian population and to investigate the relationship between this single nucleotide polymorphism...

Background Colorectal Cancer (CRC) is the third most common cancer in Iran and its early detection is necessary. This study is based on perception of people in the east of Iran toward CRC screening.   Methods In a cross-sectional study, 1060 randomly selected individuals who referred to Razavi Hospital of Mashhad, Iran, between September the 1st, 2012 and February the 28th, 2013 as patients or ...

Colorectal cancer has become the third most common cancer and leads to high mortality worldwide. Although colorectal cancer has been studied widely, the underlying molecular mechanism remains unclear. PER3 is related to tumor differentiation and the progression of colorectal cancer. High expression of miR-103 is associated with poor prognosis in patients with colorectal cancer. However, the rel...

Colorectal cancer (CRC) is among deadliest cancers all over the world. Regarding its high mortality, some researches have focused to discover new applicable diagnosis methods. In this regard, circulatory miRNAs has been received huge consideration as promising biomarkers for early detection of CRC. The study aimed to evaluate the expression level of miRNA-7, miRNA-93, and miRNA-409 in plasma of...

The colorectal cancer (CRC) subtyping consortium has unified six independent molecular classification systems, based on gene expression data, into a single consensus system with four distinct groups, known as the consensus molecular subtypes (CMS); clinical implications are discussed in this review based on articles relevant to the CMS of CRC indexed in PubMed as well as the authors’ own ...
