BRCA1 and microRNAs: emerging networks and potential therapeutic targets.

ABSTRACT: BRCA1 is a well-known tumor suppressor implicated in familial breast and ovarian cancer. Since its cloning in 1994, numerous studies have established BRCA1's role in diverse cellular and biochemical processes, such as DNA damage repair, cell cycle control, and transcriptional regulation as well as ubiquitination. In addition, a number of recent studies have functionally linked this tumor suppressor to another important cellular regulator, microRNAs, which are short (19-22 nt) RNAs that were discovered in the nematode in 1993. Soon their presence and function were validated in mammals, and since then, the role of microRNAs has been actively investigated in almost all biological processes, including cancer. In this review, we will describe recent progress in the understanding of the BRCA1 fu
