INPP1 up-regulation by miR-27a contributes to the growth, migration and invasion of human cervical cancer.

ABSTRACT: Inositol polyphosphate-1-phosphatase (INPP1) is an enzyme that is responsible for glycolysis and lipid metabolism. Here, we discovered that INPP1 expression was up-regulated in CC tissues compared to that in adjacent normal tissues by RT-qPCR. Inositol polyphosphate-1-phosphatase overexpression promoted and INPP1 knockdown suppressed cell viability, cellular migration/invasion and EMT in CC cells. To explore the mechanism of dysregulation, INPP1 was predicted to be a target of miR-27a, and a pmiRGLO dual-luciferase reporter assay showed that miR-27a bound to the 3' UTR of INPP1. RT-qPCR revealed that miR-27a was also up-regulated and had a positive correlation with INPP1 expression in CC tissues. Furthermore, shR-INPP1 could favour the malignant phenotype reversion induced by miR-27a, sugg
