microRNA-33a and b (miR-33a/b), which differ by only two nucleotides, are intronic microRNAs located within the sterol response element binding protein genes SREBF2 and SREBF1 , respectively, which code for transcription factors that regulate cholesterol and fatty acid metabolism. (regulusrx.com)
Indeed, in the absence of microRNAs, the expression of transcription factors that inhibit GnRH expression increases, and leads to the extinction of GnRH synthesis in the brain, leading to the arrest of sexual maturation, absence of puberty, and complete sterility in adult individuals. (sciencedaily.com)
The identified transcription factors influence both the global and specific gene expression of the BCLs and have possible implications for diagnosis and treat- ment. (lu.se)

In their research, the Guled team explained that "miRNA were predicted to target some of the more commonly affected genes in MPM including cyclin-dependent kinase inhibitor 2A (CDNK2A), neurofibromatosis type 2 (NF2), jun oncogene, hepatocyte growth factor and platelet derived growth factor.
