A study in mice and human RWPE-1 cells demonstrated that cadmium exposure induces prostatic fibrosis by elevating the miR-1236-3p level, which functions as a sponge for miRNA-1236-3p to stimulate the SHH signaling pathway, promoting epithelial-mesenchymal transition and collagen deposition [Huang et al. DOI:10.1002/Jat.4436].
