The goal of this research was to study the relationships between maternally expressed gene 3 (MEG3), microRNA-7 (miR-7), and RASL11B, and explore their influence on the progression of clear cell renal cell carcinoma (CCRCC). Microarray analysis was conducted using the data provided by The Cancer Genome Atlas. The expression levels of MEG3 and miR-7 in CCRCC and adjacent tissue samples were ascertained by quantitative real-time polymerase chain reaction (qRT-PCR). ⋯ RASL11B, lowly expressed in CCRCC, was a target of miR-7. After the overexpression of RASL11B, G0/G1 phase cell cycle arrest was induced; cell apoptosis was promoted; and the proliferation, invasion, and migration of CCRCC cells were inhibited. MEG3 could up-regulate RASL11B to inhibit the cell proliferation, invasion, and migration; induce G0/G1 cell cycle arrest; and promote cell apoptosis by suppressing miR-7 in CCRCC.
