Western Blot: HIF-1 alpha Antibody (H1alpha67) [NB100-105] - Induction of HIF-1 alpha & a glycolytic response by VLX600.(a) GSEA plots of hypoxia, glycolysis, mitosis & p53 networks based on the gene expression profiles of HCT116 MCS or HCT116HIF-1 alpha−/− MCS exposed for 6 h to 6 μM VLX600. NES, normalized enrichment score; P values refer to the nominal P values generated after 1,000 permutations. (b) Monolayer HCT116 cells were exposed to 6 μM VLX600 & analysed for HIF-1 alpha expression by western blotting after 6 h. (c) Spheroids were exposed to VLX600 for different times, sectioned & stained for HIF-1 alpha. The spheroid core areas were lack of HIF-1 alpha induction. Scale bar, 250 μm (d) HCT116HIF-1 alpha−/− MCS show strong positivity for active caspase-3 in core areas. Spheroids were fixed & stained for active caspase-3 5 days after formation; scale bar, 250 μm. (e) HCT116 & HCT116HIF-1 alpha−/− MCS were exposed for 72 h to VLX600 (6 μM) followed by drug wash-out. Diameters of the MCS were recorded & converted to volumes. Volume determinations are inaccurate at 4–10 days since MCS disintegrate & dead cells stick to spheroid structures (the transient increase in the volume of VLX600-treated HCT116HIF-1 alpha−/− MCS is likely to be an artifact). Shown are means±s.d. (n=3). (f) HCT116, HCT116HIF-1 alpha−/− or HCT116p53−/− monolayer cells were exposed to VLX600 & viability was determined after 72 h using the fluorometric microculture cytotoxicity assay. Shown are means±s.e.m. (n=3). (g) Monolayer HCT116 cells were exposed to 6 μM VLX600 & analysed for p53 expression by immunoblotting at the times indicated.
