Immunoblot analysis of hypoxia‐inducible factor (HIF)‐1α and vascular endothelial growth factor (VEGF) proteins in (a) TNB9 and (b) TS‐N‐2nu xenografts. Inhibiting phase, tumors on day 10 in TNB9, and on day 7 in TS‐N‐2nu. Regrowing phase, tumors on day 14 with conventional‐dose treatment and on day 19 with low‐dose treatment in TNB9, and on day 15 in TS‐N‐2nu. For protein loading controls, actin levels were checked.
