TGFB1 and posterior cortical atrophy: Dai et al. recently reported a negative correlation of ZEB1 expression and TGF-β signaling activity with miR-33a-5p expression in PCa [50]: downregulated miR-33a-5p expression in PCa tissues with bone metastases and bone-derived cells was positively correlated with advanced clinicopathological characteristics, shorter overall survival, and bone metastasis-free survival of the patients.
