Moreover, pathway terms related to Yersinia infection and osteoclast differentiation, including focal adhesion kinase (FAK) and steroid receptor coactivator (Src) signaling, NF-κB signaling, and MAPK signaling, were significantly enriched in the ILG and GU groups during the 0–24-h period after stimulation. The gene discussed is PTK2; the disease is Yersinia infectious disease.
