MiR-219 inhibits the growth and metastasis of TSCC cells by targeting PRKCI.


ABSTRACT: Tongue squamous cells carcinoma (TSCC) is the most common type in oral cancers. Recently, accumulating evidence suggests that microRNAs (miRNAs) play critical roles in tumorigenesis. Here, we demonstrated that miR-219 was significantly downregulated in TSCC tissues and cell lines. miR-219 overexpression remarkably suppressed cell proliferation, colony formation, migration and invasion of TSCC cells. In addition, protein kinase CI (PRKCI) was identified as a target of miR-219, and overexpression of PRKCI could significantly attenuated the tumor suppressive effects of miR-219. Furthermore, PRKCI inversely correlates with miR-219 in TSCC tissues. Taken together, miR-219 inhibited growth and metastasis by targeting PRKCI and might be used as a potential target for the treatment of TSCC.
