HNRNPC and obesity disorder: 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).
