ANGPTL4 is regulated by peroxisome proliferator-activated receptor γ (PPARγ) (Aryal et al., 2019), who has been observed to be significantly increased in malignant ovarian tumours (grade 1, 2 and 3) compared to benign and borderline tumours (Zhang et al., 2005). Here, ANGPTL4 is linked to ovarian cancer.
