Colorectal cancer: role of commensal bacteria and bystander effects

Role of Molecular Biomarkers in Colorectal Cancer

Colorectal cancer (CRC) is amongst the most widespread cancers and is a most common cause of cancer associated mortality universally. Since previous decades, it has been cleared that CRC develops owing to the buildup of a series of genetic and epigenetic changes in the normal colonic epithelium. Regardless of the current development in surgery and therapies, overall survival of end stage CRC pa...

The Role of Target and Bystander Cells in Dose-Response Relationship of Radiation-Induced Bystander Effects in Two Cell Lines

Commensal bacteria drive endogenous transformation and tumour stem cell marker expression through a bystander effect

OBJECTIVE Commensal bacteria and innate immunity play a major role in the development of colorectal cancer (CRC). We propose that selected commensals polarise colon macrophages to produce endogenous mutagens that initiate chromosomal instability (CIN), lead to expression of progenitor and tumour stem cell markers, and drive CRC through a bystander effect. DESIGN Primary murine colon epithelia...

Colorectal Cancer and Prevention

   سرطان کولون و رکتوم یکی از انواع شایع - سابقه ابتلا به سرطان کولورکتال یا پولیپ های سرطانهاست که با وجود ایجاد مشکلات و عوارض متعدد در سلامتی انسانها، هنوز به طور جدی و کافی مورد توجه قرار نگرفته است. به طوریکه در سال ۲۰۰۴ بیش از ۱۳۰ هزار مورد جدید ابتلا به این بیماری در امریکا گزارش شده است. و طبق آمارهای انجمن سرطان آمریکا در سال ۲۰۰۲، از ۱۸۳۳۰۰ مورد ابتلا به سرطان کولورکتال۵۶ هزار مورد ب...

The Role of Angiogenesis in Colorectal Polyps and Cancer, a Review

ABSTRACT           Colorectal cancer remains a leading cause of morbidity and mortality worldwide. Most colorectal cancers begin as a growth of tissue called a polyp, some types of which can change into cancer over the course of several years. Angiogenesis, the formation of new blood vessels, is known to play a key role in the initiation, growth and...
