Abstract

More and more studies have reported that dysregulation of microRNAs (miRNAs) leads to the proliferation and EMT of multiple cancers. Recently, several reports have demonstrated that dysregulation of miR-4262 occurs in numerous cancers. However, its role and precise mechanism in human cervical cancer (CC) have not been well clarified. Hence, this study aimed to explore the biological roles and precise mechanisms of miR-4262 in CC cell lines. The level of miR-4262 was found to be significantly decreased in CC tissues and cell lines. Moreover, decreased expression of miR-4262 was closely related to increased expression of Kaiso (ZBTB33), which belongs to the BTB/POZ family, in CC tissues and cell lines. The proliferation and EMT of CC cells were inhibited by a miR-4262 mimic. However, downregulation of miR-4262 enhanced the proliferation and EMT of CC cells. Next, bioinformatics analysis predicted that miR-4262 might directly target the Kaiso gene. Besides, luciferase reporter assay had confirmed this result. Moreover, introduction of Kaiso in CC cells partially blocked the effects of miR-4262 mimic. In conclusion, miR-4262 suppressed the proliferation and EMT of CC cells by directly downregulating Kaiso.
