CDCA5, DNMT1, UNKL, HSPD1, KLC1, CBX2, RPMS17, LAMB1, SLC3A2, PARP12 and COMMD10 were selected as the hub genes, and elucidation of the function of these hub genes might provide new insights into the molecular mechanisms of miR‐542‐5p in osteosarcoma. The gene discussed is LAMB1; the disease is osteosarcoma.
