To further elucidate the role of VB and HMGA2 in relation to protein expression and autophagy of U87 and U251 cell lines, the expression of let‐7g‐5p, Beclin1, β‐catenin and HMGA2 in GBM cells was determined by laser confocal microscopy, RT‐qPCR and Western blot analysis. Here, BECN1 is linked to glioblastoma.
