miR-182 facilitates invasion and EMT by targeting Numb in Malignant Pleural Mesothelioma
Malignant Pleural Mesothelioma (MPM) is a highly aggressive tumor which need effective therapeutic methods to improve the prognosis. We carried out this study to explore the role of miR-182 in MPM development, its correlation with Numb expression and EMT.
First, we investigated the level of miR-182 and Numb-mRNA by qRT-PCR. Furthermore, we introduced the putative miR-182 binding site into a luciferase reporter plasmid to illustrate the impact of miR-182 on Numb. Then, we down-regulated the expression of miR-182 with/without Numb knocked down in NCI-H2452 cells to investigated their effect. Data were presented as mean ± SD of three independent experiments. Student’s test, correlation analysis and analysis of variance (ANOVA) were used.
Our results revealed that miR-182 has a high level of expression in MPM, it has a negative correlation with Numb and targeted Numb in MPM cells. miR-182 facilitated the invasion of MPM cells while down-regulation of miR-182 restrained the progression of EMT and made MPM cells more susceptible to pemetrexed.
miR-182 and Numb can serve as potential therapeutic targets for MPM.
