ANGPTL4 and ovarian adenocarcinoma: In addition, ANGPTL4 is highly expressed in A2780 and MISIIR-TAg-induced ovarian carcinoma cells and in CAOV3 and OVCAR3 ovarian adenocarcinoma cells (Fig. 1a–c, Additional file 1: Fig. S1a); however, the low to negligible levels of ANGPTL4 in other types of ovarian tumors limit these conclusions.
