OBJECTIVE Recent studies have revealed that long non-coding RNAs (lncRNAs) have a crucial role in tumor progression. Renal cell cancer (RCC) is a common type of fatal gynecological cancer worldwide. This study aims to identify the role of lncRNA Small nucleolar RNA host gene 7 (SNHG7) in the progression of RCC. PATIENTS AND METHODS Expression of lncRNA SNHG7 in both RCC cells and 50 pairs of tissue samples was detected by Real-time quantitative polymerase chain reaction (RT-qPCR). Moreover, the function of SNHG7 was identified by performing cell apoptosis assay, colony formation assay and proliferation assay in vitro. The underlying mechanism assays including RT-qPCR and Western blot assay were conducted. RESULTS SNHG7 expression was remarkably upregulated in tumor tissues when compared with adjacent tissues. Moreover, RCC cell proliferation was inhibited and cell apoptosis was promoted after knockdown of SNHG7 in vitro. Moreover, after knockdown of SNHG7, CDKN1A was upregulated at mRNA and protein level in vitro. Furthermore, the expression of CDKN1A in tumor tissues was negatively correlated to the expression of SNHG7. CONCLUSIONS These results above suggest that SNHG7 could promote cell proliferation and inhibit cell apoptosis in RCC through downregulating CDKN1A, which may offer a new therapeutic intervention for RCC patients.
