To validate the expression level of heterogeneous nuclear ribonucleoprotein C (HNRNPC), heterogeneous nuclear ribonucleoprotein A2/B1 (HNRNPA2B1), and fat mass and obesity-associated protein (FTO), we applied a Western blot, and the results indicate that HNRNPC was significantly overexpressed in the endometriosis group while the other two genes were obviously downregulated at the protein level (Figure 2D–G). The gene discussed is HNRNPA2B1; the disease is Obesity.
