REPIN1 and osteoporosis: The function of REPIN1 has not been thoroughly studied since discovered, but the results of existing studies suggest that Repin1 may be worthy of study as a candidate gene in the following processes: adipogenesis, glucose and fatty acid transport, lipid droplet formation and fusion, which plays a regulatory role in fat formation [35, 36] Whether REPIN1 can affect the occurrence of osteoporosis by regulating iron metabolism has not been reported.
