In TGF-β signaling, the Type I/II receptors and Type I/II BMPR with essential roles in transferring TGF-β signal from the extracellular space to the cytoplasm were potentially targeted by identified miRNAs, which inferred the latent pathogenesis of these miRNAs in TGF-β-related processes of PCa metastasis.44,45. This evidence concerns the gene TGFB1 and posterior cortical atrophy.
