LASP1 knockdown reduces tumor growth and promotes chemosensitivity in vivo. a U87 cells were transfected with lentivirus-based shRNA against LASP1, and western blotting was performed to determine knockdown efficiency; (b) qRT-PCR assay showed inhibition of LASP1 at the mRNA level; (c) stable construction tumor cells were injected subcutaneously into the back of nude mice to detect proliferative ability and chemosensitivity to TMZ. Tumor volume and weight were measured at 30 days after injection and expressed as the mean ± SD, n = 5; (d) proliferative ability of tumor cells was measured by Ki-67 and apoptosis rate was derived by cleaved caspase3 immunohistochemical staining, Scale bar, 50 μm. ^* P < 0.05, ^** P < 0.01. ^***p < 0.001
