In contrast to FTH1, we observed the highest levels of BRPF1, OSBP, PHC3, and UACA in samples taken from patients with BPH, with levels of all four genes being significantly higher in CU samples compared to healthy control samples or PCa-HS samples, although not necessarily PCa-LS samples. The gene discussed is OSBP; the disease is benign prostatic hyperplasia.
