In addition, several energy metabolic processes, such as the PI3K-Akt pathway (EPHA2, FLT4, ITGA5, and LPAR6), cholesterol metabolism (APOE and CD36), and insulin resistance (FOLR1, CALM14, and PPP1R3A), were enriched in ApoE4 mice (Fig. 1i). The gene discussed is PPP1R3A; the disease is Insulin resistance.
