Abstract
<b><i>Background:</i></b> The molecular heterogeneity of clear cell renal cell carcinoma (ccRCC) leads to a high mortality of the disease, which seriously threatens the life of patients. Therefore, this study explored the functional significance and mechanism of microRNA-155-5p and nuclear receptor subfamily 3 group C member 2 (NR3C2) in the regulation of ccRCC. <b><i>Methods:</i></b> Expression levels of microRNA-155-5p and NR3C2 mRNA in ccRCC cells were analyzed by qRT-PCR, and the protein expression of NR3C2 in human ccRCC cells was measured by Western blot. Biological functions were determined through a series of in vitro experiments. The interaction between microRNA-155-5p and NR3C2 was tested by luciferase reporter gene assay. In addition, the effect of overexpressed or silenced microRNA-155-5p on cell phenotypes was evaluated in ccRCC cells. <b><i>Results:</i></b> Experimental data suggested that overexpression or silencing of microRNA-155-5p in ccRCC could boost or suppress cancer cell proliferation and other malignant behaviors. Rescue experiments revealed that microRNA-155-5p facilitated the proliferation, migration, and invasion and suppressed the apoptosis of ccRCC by directly inhibiting the expression of NR3C2. <b><i>Conclusions:</i></b> This is the first study to generate new insights into the role of microRNA-155-5p/NR3C2 interaction in promoting the process of ccRCC, and it is possible to bring a turning point for the treatment of ccRCC.
