IGF1 and cancer: For IGF1, whose expression increases in the transition from borderline to low serous, we found a moderate correlation between its expression and T cell in low serous tissue (r = 0.5, p = 0.002), and a moderate correlation between cancer-associated fibroblast in borderline and low serous tissue (r = 0.5, p = 0.0059, r = 0.48, p = 0.0036, respectively).
