Gastrins, iron homeostasis and colorectal cancer

Iron homeostasis and distal colorectal adenoma risk in the prostate, lung, colorectal, and ovarian cancer screening trial.

Red meat consumption has been positively associated with colorectal cancer; however, the biological mechanism underlying this relationship is not understood. Red meat is a major source of iron, which may play a role in colorectal carcinogenesis via increased crypt cell proliferation, cytotoxicity, and endogenous N-nitrosation. In a nested case-control study within the Prostate, Lung, Colorectal...

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...

Hypoxia-inducible factor-2α activation promotes colorectal cancer progression by dysregulating iron homeostasis.

Hypoxia-inducible factor (HIF), a key modulator of the transcriptional response to hypoxia, is increased in colon cancer. However, the role of HIF in colon carcinogenesis in vivo remains unclear. In this study, we found that intestinal epithelium-specific disruption of the von Hippel-Lindau tumor suppressor protein (VHL) resulted in constitutive HIF signaling, and increased HIF expression augme...

The deubiquitinase USP28 controls intestinal homeostasis and promotes colorectal cancer.

Colorectal cancer is the third most common cancer worldwide. Although the transcription factor c-MYC is misregulated in the majority of colorectal tumors, it is difficult to target directly. The deubiquitinase USP28 stabilizes oncogenic factors, including c-MYC; however, the contribution of USP28 in tumorigenesis, particularly in the intestine, is unknown. Here, using murine genetic models, we ...
