ANGPTL4 and neoplasm: We found that the ANGPTL4 protein expression significantly increased in all tumor cells when compared with CM control (p < 0.05 by the two-sided Student’s t-test), and MDA-MB-231 and HCC1937 cells in ACM expressed significantly higher ANGPTL4 than MCF-10A and MCF-7 cells in ACM (p < 0.05 by the two-sided Student’s t-test).
