Dysregulation of microRNA-150 (miR-150) is commonly observed in solid tumor and has been reported to be involved in multiple important biological processes, such as cell proliferation, apoptosis, and metastasis. Elevated miR-150 level was also detected in cervical carcinoma, whereas its function in cancer progression has not been studied yet.
The expression of miRNA-150 in cervical carcinoma was compared with normal cervical tissue and using qRT-PCR. The effects of miR-150 on cell cycle and apoptosis, as well as the expression of cycle- and apoptosis-related genes, were determined using flow cytometry, TUNEL assay, qRT-PCR, and Western blot, respectively. The direct target of miR-150 was confirmed using 3' untranslated region (UTR) luciferase reporter assay.
miR-150 promotes cervical cancer cell survival and growth, while the inhibition of miR-150 suppresses these actions. miR-150 also induced the cell cycle progression from G1/G0 to S phase, resulting in an enhancement of growth. Several cell cycle- and apoptosis-related genes, CyclinD1, p27, BIM, and FASL were modulated by miR-150. Moreover, miR-150 directly reduced the expression of FOXO4, which regulates the expression of CyclinD1, p27, BIM, and FASL, by targeting its 3' UTR.
Taken together, our data demonstrated that elevated miR-150 targets FOXO4 expression and therefore regulates multiple genes expression, resulting in cervical cancer cell growth and survival.
