Differentially expressed microRNA-218 modulates the viability of renal cell carcinoma by regulating BCL9.

The present study assessed the expression profiles of numerous microRNAs (miRs; miR-141, miR-187, miR-206, miR-218, miR-335 and miR-204) in 25 pairs of renal cell carcinoma (RCC) tissue samples and adjacent non-cancerous tissue. Reverse transcription‑quantitative polymerase chain reaction (RT‑qPCR) analysis revealed that miR‑218 was significantly downregulated in RCC tissue samples. Next, web‑based algorithms were used to identify B‑cell lymphoma (BCL)9 as a possible target of miR‑218, which was confirmed by a subsequent luciferase assay.
