We found that in MTA1‐high group, 69.2% showed high levels of HIF‐1α, whereas in MTA1‐low group, 83.3% showed low HIF‐1α, once again indicating positive relationship between MTA1 and HIF‐1α expression in prostate tumors (Fig. 6A and B). The gene discussed is HIF1A; the disease is prostate neoplasm.
