LncRNA HCG11/miR-579-3p/MDM2 axis modulates malignant biological properties in pancreatic carcinoma via Notch/Hes1 signaling pathway

miR-579-3p directly targeted MDM2 to suppress MDM2 expression. (A) qPCR assay was used to examine MDM2 expression in 20 pairs of pancreatic carcinoma tissues and corresponding normal tissues. ***pB) MDM2 expression in pancreatic carcinoma cell lines (BxPC-3, Capan-2, SW1990, PANC-1 and AsPC-1) was also detected by qPCR assay. **p***pC, D) Analysis from qPCR revealed that MDM2 expression was positively related to HCG11 expression, and negatively associated with miR-579-3p expression. (E) The binding sites between miR-579-3p and MDM2 were exhibited. (F, G) The luciferase activity in PANC-1 and AsPC-1 cells was measured by the luciferase reporter assay after transfected with miR-579-3p mimic/NC and MDM2-mut/wt vector.
