The expression of SOCS3, a major regulator of infection and inflammation associated with IL-6 and LIF, was observed to have lower values in both the LPS and LPS-PKCOS groups than in the CT group, and no difference was revealed between the LPS and LPS-PKCOS groups (Figure 5D), while the expression of the LIF gene showed no difference among the three groups (CT, LPS and LPS-PKCOS; Figure 5E). The gene discussed is LIF; the disease is infection.
