The mRNA expression levels of IGF-2, TGF-β, and FGF in the BPH cohort were increased compared to those in the NC cohort; nevertheless, the finasteride and PV groups showed significant reductions in the expression levels of IGF-2, TGF-β, and FGF compared to those in the BPH cohort (Figure 6). Here, IGF2 is linked to benign prostatic hyperplasia.
