miR-181b modulates glioma cell sensitivity to temozolomide by targeting MEK1

Purpose Recent studies have reported that miR-181b contributes to chemoresistance in several cancer types and functions as a tumor suppressor in glioma. This study aimed to explore whether miR-181b could enhance the chemotherapeutic effect of temozolomide in glioma cells and sought to identify the candidate target genes which mediated the effect.
