TGFB1 and benign prostatic hyperplasia: IF staining and western blot analysis revealed that TGF-β stimulation reduced E-cadherin protein levels but increased vimentin, N-cadherin, and snail protein levels (Figure 3B‒D) in BPH-1 cells, miR-1202 overexpression further amplified, whereas miR-1202 inhibition partially attenuated the effects of TGF-β on EMT markers (Figure 3B‒D).
