MiR-1204 promotes ovarian squamous cell carcinoma growth by increasing glucose uptake

ABSTRACTMiR-1204 has been recently identified as an oncogenic miRNA in breast cancer. Our study aims to investigate the role of miR-1204 in ovarian squamous cell carcinoma. Expression of miR-1204 and glucose transporter 1 in ovarian biopsies and plasma of both OC patients and healthy controls was detected by qRT-PCR. Correlations between patients’ clinicopathological data were analyzed by Chi-square test. MiR-1204 overexpression OC cell lines were established. Expression of GLUT-1 protein was detected by western blot. Glucose uptake was measured by glucose uptake assay. Cell proliferation was detected by CCK-8 assay. We found that miR-1204 expression was significantly correlated with tumor size. Expression levels of miR-1204 and GLUT-1 were significantly high in OC patients. Expression levels of miR-1204 were positively correlated with expression levels of GLUT-1 in OC patients. MiR-1204 overexpression significantly promoted GLUT-1 expression, glucose uptake and cell proliferation. MiR-1204 may promote ov...
