Abstract

MicroRNA (miR)-21 has many regulatory functions in the cell, including activities in cancer cells and cancer stem cells. Large tumor suppressor gene 1 (LATS1) is a target of miR‑21 that could mediate several of these phenotypes. This study explored the effect of miR‑21 silencing in renal cancer cell function and LATS1 expression. Silencing of miR‑21 in Caki‑2 cells reached an efficiency of 55‑60%. This was sufficient to detect decrease in Caki‑2 cell proliferation and migration invasion capacity. miR‑21 silencing increased LATS1 expression at both mRNA and protein levels. The number of tumor spheres formed by cells expressing si‑miR‑21 was significantly reduced and the expression of tumor stem cell markers Nanog and CT3/4 were significantly downregulated. miR‑21 seems to regulate LATS1 expression in renal cancer Caki‑2 cells, resulting in reduced proliferation, invasion, and cancer stem cell phenotype. miR‑21 may promote malignant phenotype of tumor cells through LATS1 silencing, which can be regarded as a new target candidate gene for renal cancer treatment.
