Fig. 3: m6A reader IGF2BP2 enhanced the stability of lncRNA CASC9.

A In the GBM cohort, IGF2BP2 was found to be upregulated according to the GEPIA dataset (http://gepia.cancer-pku.cn/index). B Western blot analysis found the IGF2BP2 expression in U87MG cells with IGF2BP2 overexpression by plasmids transfection. C RNA stability assay demonstrated the remaining lncRNA CASC9 in U87MG cells when treated with Act D. D MeRIP-Seq data by IGV showed the two m6A modification sites in the 3ʹ-UTR of CASC9. E The location of m6A modification sites in the CASC9 gene. F MeRIP-qPCR demonstrated the CASC9 expression in GBM cell lines (U87MG) using anti-m6A antibody. G RIP-qPCR showed the interaction within CASC9 and IGF2BP2 in U87MG cells using anti-IGF2BP2 antibody. Data are presented as the mean ± SD. **P < 0.01.
