The ratio of the relative migration in miR-182-5p inhibitor group was elevated by 1.51 times in 786-O (P?=?0.001) and raised by1.58 times in Caki-1 (P?=?0.005) (Fig. we found that UCA1 was significantly up-regulated in renal cancer. Moreover, increased UCA1 expression was positively correlated with differentiation and advanced TNM stage. Further experiments demonstrated that knockdown of UCA1 inhibited malignant phenotypes and Notch signal path of renal cancer cells, and miR-182-5p was reverse function as UCA1. UCA1 functioned as a miRNA sponge to positively regulate the expression of Delta-like ligand 4(DLL4) through sponging miR-182-5p and subsequently promoted malignant phenotypes of renal cancer cells, thus UCA1 playing an oncogenic role and miR-182-5p as an antioncogenic one in renal cancer pathogenesis. Conclusion UCA1-miR-182-5p-DLL4 axis is involved in proliferation and progression of renal cancer. Thus, this study demonstrated that UCA1 plays a critical regulatory role in renal cancer cell and UCA1 may serve as a potential diagnostic biomarker and therapeutic target of renal cancer. value of less than 0.05 was considered to be statistically significant. Results Up-regulation of UCA1 and low-expression of miR-182-5p in renal cancer tissues, cells and both correlation with clinical pathologic factors The relative expression level of UCA1 and Cytarabine miR-182-5p was detected by using Real-Time qPCR in a total of 88 patients with renal cancer. Compared to matched normal peritumoral tissues, the UCA1 expression was up-regulated remarkably in 68.2% (60 of 88) of cancer tissues (valuevalue High (n?=?24) Low (n?=?64)
