To study the potential role of C1QTNF3 in tumor immunity and/or progression, we first characterized the macrophage infiltration in E0771 tumors, tumor-associated and control IWAT and spleen of untreated lean and HFD-induced obese female mice (body weight: 23.9±0.5 vs. 36.0±2.1 g, p<0.0001). The gene discussed is C1QTNF3; the disease is neoplasm.
