In this study, we compared the expression of Magmas with 4-Hydroxynonenal (4-HNE), a product produced by lipid peroxidation in cells in response to oxidative stress in high-grade (n = 3) and benign (n = 3) ovarian tumours, which had high and low expressions of Magmas (Figure 3). Here, PAM16 is linked to ovarian neoplasm.
