TGFB1 and osteogenesis imperfecta: Nine miRNAs that were identified in OI but not in the controls, namely hsa-miR-19a-3p, hsa-miR-19b-3p, hsa-miR-133a-3p, hsa-miR-200b-3p, hsa-miR-204-5p, 216a-5p, hsa-miR-377-3p, hsa-miR-449a, and hsa-miR-590-5p, have been previously reported to regulate the TGF-β and Wnt signaling pathways, indicating their essential role in the regulation of genes involved in bone formation and turnover [28,29,32,33,34].
