Concurrently, insulin resistance, chronic inflammation, and obesity contribute to ROS overproduction, while the activity of antioxidant enzymes (such as superoxide dismutase and glutathione peroxidase) are significantly reduced ( In PCOS, excessive ROS inflict damage on oocytes and granulosa cells, disrupt the follicular microenvironment, and impair follicular development and ovulation ( e.g ., CYP17) in ovarian theca cells, exacerbating hyperandrogenemia ( e.g ., vitamin C, vitamin E, N-acetylcysteine) may mitigate oxidative damage, improve insulin sensitivity, and restore ovarian function by neutralizing ROS ( 3.2 Autophagy Autophagy is a fundamental cellular process responsible for degrading and recycling damaged organelles and proteins, playing a critical role in maintaining cellular homeostasis

This suggests that the reduction in GPX4 may mediate ferroptosis in some nigral neurons during PD progression, while the elevated GPX4 in surviving neurons represents a protective response against oxidative stress and neurodegeneration

These tools represent a major advancement in the early detection and staging of CKD and AKI
