BACKGROUND A colorectal cancer may develop through a particular molecular genetic pathway, raising the question of whether the particular molecular changes are random, or are unique to the particular segment of colon. We wanted to determine whether molecular changes found within a colorectal cancer might also be detected in separate adenomas and polyps removed from the same area of colon at sur...

In the United States, more than 150, 000 cases of colorectal cancers are diagnosed annually, making colorectal cancers a major cause of morbidity and mortality. Hereditary colorectal cancers are thought to account for up to 30% of the total number, 5% of which have a known genetic background. Colorectal cancers occurring at ages less than 50 are considered young-onset and are thought to make up...

PURPOSE Oncostatin M (OSM) is an interleukin-6 cytokine family member, which inhibits cell proliferation and induces cell differentiation and apoptosis in cancers. In melanoma cells, epigenetic silencing of OSM receptor (OSMR) by histone deacetylation contributes to escape of cell growth control by OSM. However, the silencing of OSMR by DNA methylation in any cancer has not been examined. EXP...

PURPOSE Sporadic colorectal cancers with high-frequency microsatellite instability (MSI-H) are related to hypermethylation of mismatch repair (MMR) genes and a higher frequency of BRAF mutations than Lynch syndrome. We estimated the feasibility of hereditary colorectal cancer based on hMLH1 methylation and BRAF mutations. METHODS Between May 2005 and June 2011, we enrolled all 33 analyzed pat...

Microsatellite instability implying multiple replication errors (RER+ phenotype) characterizes a proportion of colorectal carcinomas, particularly those from patients with the hereditary non-polyposis colorectal carcinoma syndrome. We studied the incidence of microsatellite instability in more than 500 sporadic tumors representing 6 different types of cancer. Apart from colorectal carcinoma [se...

Colorectal cancer is one of the three most common cancers in the world and also one of the four leading causes of death among cancerous patients with global prevalence [1,2]. This cancer is associated with a high incidence and mortality among developed countries [3]. In Iran, which is located in southwest Asia, colorectal cancer is one of the five most common cancers in both genders and in the ...

adipocytokines, hormones secreted from adipose tissue, have been shown to be associated with many cancers such as breast, prostate and colorectal cancer. recent studies have indicated that resistin and visfatin, two of these adipokines have high level plasma concentrations in colorectal cancer patients and may be promising biomarkers for colorectal cancer. the aim of this study was to identify ...

background: colorectal cancer is one of the most common gastrointestinal cancers accounting for about 10 percent of cancer-related mortalities. the present study was performed in order to investigate the relationship between nutritional factors and colorectal cancer risk in the population of yazd, iran.   methods: this case-control study was conducted on 60 patients with colorectal cancer and 1...

IQGAPs is a family of proteins which comprises three members, in humans. The expression pattern and role of IQGAP1 has been well established in many cancers, whereas those of IQGAP2 and IQGAP3, have mostly remained unexplored. We used available large datasets, to explore the pan-cancer status of these two genes in-silico. Here we have analysed their mRNA expression and correlation with survivab...
