title: The microRNA biogenesis machinery: regulation by steroid hormones and alterations in cancer.
abstract: MicroRNAs are a class of non-coding RNAs that regulate gene expression at the post-transcriptional level. The major proteins of the canonical microRNA biogenesis pathway in human are: Drosha, DGCR8, DDX5, DDX17, Exportin 5, Dicer and Argonaute 2. Recent studies suggest that gene expression of some canonical microRNA biogenesis components could be regulated by steroid hormones. Furthermore, various alterations in microRNA biogenesis have been associated with diseases like cancer. Due to the importance of microRNAs in cell physiology, the study of the factors that regulate or affect their biogenesis is critical.
