FAM107A and autoimmune thrombocytopenic purpura: FAM107A is a candidate tumor suppressor gene located on chromosome 3p21.1 that encodes a protein of 144 amino acids.[50] FAM107A has dual functions in tumor biological behaviors, including inducing apoptosis in early tumors and promoting invasion.[38, 51] In terms of FAM107A mechanisms, we demonstrated that FAM107A plays an essential role in regulating the immunomodulatory function of ITP‐MSCs, at least in part, through promoting apoptosis.
