Role of stat proteins in inflammatory bowel diseases and colon carcinogenesis

STAT mediators comprise a family of seven proteins, that play a key role in intracellular signaling. They are involved in cell differentiation, proliferation and cell death. This article presents a description of STAT proteins with a focus on their probable role in pathology of alimentary system, particularly inflammatory bowel disease and colon carcinogenesis. In inflammatory bowel disease action of STAT3, STAT1, STAT 4 predominates. STAT1 and STAT3 play remarkable roles in colon carcinoma. It was discovered that STAT1 blocks cell proliferation in cell lines of colorectal cancer.

Connections gap and their involvement in apoptosis and carcinogenesis

GAP junctions multicellular organisms are a necessary support member homeostatic control of growth and differentiation of cells. The existence of such a route of communication between the cells remaining in close contact is a prerequisite for the proper functioning of the body. Communication impairment (loss of connection gap) between the cells violates the homeostasis of these cells. The characteristics of cancer cells are abnormal for the control of growth and / or differentiation of these cells.
