Abstract
Breast cancer is the most frequent cancer among women. Despite extensive research in recent years the molecular basis of breast cancer development, growth and metastasis remains unclear. Numerous studies highlight the involvement of BMI-1 in tumorigenesis. BMI-1 protein is a key component of Polycomb Repressive Complex 1, which by ubiquitinylation of histone H2A, regulates expression of genes involved in various cellular processes including cell cycle, proliferation and programmed cell death. Overexpression of BMI-1 has been often associated with breast cancer development and progression. This review summarizes the current state of knowledge of BMI-1's role in breast cancer biology and its potential significance as prognostic marker and potential target of new anticancer therapy.
期刊介绍：
Cellular Physiology and Biochemistry is a multidisciplinary scientific forum dedicated to advancing the frontiers of basic cellular research. It addresses scientists from both the physiological and biochemical disciplines as well as related fields such as genetics, molecular biology, pathophysiology, pathobiochemistry and cellular toxicology & pharmacology. Original papers and reviews on the mechanisms of intracellular transmission, cellular metabolism, cell growth, differentiation and death, ion channels and carriers, and the maintenance, regulation and disturbances of cell volume are presented. Appearing monthly under peer review, Cellular Physiology and Biochemistry takes an active role in the concerted international effort to unravel the mechanisms of cellular function.
