MicroRNAs as gatekeepers of apoptosis

Subbaya Subramanian et al. J Cell Physiol. 2010 May.

Abstract

Apoptosis is a well-orchestrated cellular mechanism that balances the effects of cell proliferation and cell death. MicroRNAs (miRNAs) have been shown to control cell growth, differentiation, and apoptosis; and can be significantly deregulated in many cancers types. In fact, the ability to evade apoptosis is a hallmark of tumorigenesis. Although the role of miRNAs in the regulation of apoptosis is not fully understood, the recent influx of data strongly suggests that miRNAs play a significant role in regulating programmed cell death, or apoptosis. The genes involved in apoptotic pathways can be broadly classified as pro-apoptotic and anti-apoptotic. Many of these apoptotic genes, irrespective of their positive or negative functional role in apoptosis, are regulated by miRNAs. In this review, we discuss the emerging role of miRNA-mediated gene networks in the control of apoptosis.
