RESUMO
OBJECTIVE: Long noncoding RNAs (lncRNAs) have been well concerned in tumor researches, which are believed to influence tumorigenesis and tumor progression. This study aims to uncover the role of LINC00707 in clear cell renal cell carcinoma (ccRCC) and the underlying mechanism. MATERIALS AND METHODS: Differentially expressed lncRNAs in ccRCC tissues and renal epithelial tissues were analyzed in The Cancer Genome Atlas (TCGA), and LINC00707 was screened out. Expression level of LINC00707 in ccRCC cell lines was determined as well. Regulatory effects of LINC00707 on influencing proliferative, migratory, and invasive abilities of 786-O and 769-P cells were assessed. At last, relative levels of epithelial-mesenchymal transition (EMT)-related genes E-cadherin and N-cadherin in 786-O and 769-P cells were detected by quantitative real time-polymerase chain reaction (qRT-PCR) and Western blot. RESULTS: LINC00707 was upregulated in ccRCC tissues and cell lines. Silence of LINC00707 attenuated proliferative, migratory, and invasive abilities of 786-O and 769-P cells. Moreover, knockdown of LINC00707 upregulated E-cadherin and downregulated N-cadherin in ccRCC cells at both mRNA and protein levels. CONCLUSIONS: LINC00707 is upregulated in ccRCC, which could promote cancer cells to proliferate, migrate, and invade. LINC00707 accelerates the progression of ccRCC by activating EMT pathway.
