Figure 4. HMOX1 promotes GBM cell proliferation and invasion through activation of the HIF1α/SPOP signaling axis. T98G cells were transfected with oe-HMOX1, oe-HMOX1 + sh-HIF1α or oe-HMOX1 + sh-SPOP. (A) Western blot of HMOX1, HIF1α and SPOP proteins in T98G cells. (B) Proliferation of T98G cells measured by CCK-8 assay. (C) Invasion of T98G cells measured by Transwell assay. (D) Western blot of the CCND1, E-cadherin, MYC, MMP-7, and N-cadherin proteins in T98G cells. *p < 0.05, compared to oe-NC + sh-NC-transfected T98G cells. #p < 0.05, compared to oe-HMOX1 + sh-NC-transfected T98G cells. The cell experiment was run in triplicate independently.
