Ovarian cancer is a gynecological cancer of high mortality rate. Most of the ovarian cancer origin from the surface epithelium of the ovaries. Ovarian cancers gain metastatic and invasive properties from various biochemical events taking place during tumorogenesis. MicroRNAs (miRNA) are non-coding RNAs and they have an important function of inhibiting translation of specific mRNAs in the cytoplasm. Present study uses two ovarian cancer cell lines as model to study the differential expression of miR-125a, miR-200a, and miR-199a, and provides indirect proof for possible relationship between miR-199a and its predicted target gene Glycogen Synthase Kinase 3 {beta} (GSK3{beta}). As expected the expression of these three microRNAs are decreased in metastatic ovarian cancer cell line A2780 compared to epithelial ovarian cancer OVCAR3. Reciprocal expression pattern of miR-199a and its predicted target GSK3{beta} was found in two different cell lines providing information on possible inhibitory role of miR-199a against GSK3{beta}.
