Recent work suggests the involvement of miR-193a-5p in suppressing hepatocarcinogenesis [28] and human osteosarcoma cell metastasis [29], controlling cisplatin chemoresistance in primary bone tumors [30], reducing intestinal inflammation [31], and mediating protection against staphylococcal enterotoxin B-induced acute lung injury [32]. This evidence concerns the gene PPIB and osteosarcoma.
