Eight weeks of aerobic exercise significantly activated the System Xc−/GPx4 signaling pathway in the prefrontal cortex of APPswe/PS1dE9 transgenic AD mice, up-regulated FTL and BACE1 expression, significantly downregulated 4-HNE levels, inhibited oxidative stress, lipid peroxidation, and ferroptosis, reduced Aβ positivity, alleviated neuronal morphological abnormalities, and improved learning and memory functions in AD mice (Li et al., 2024a). The gene discussed is GPX4; the disease is Alzheimer disease.
