“…Oxidative stress is initially produced by accumulation of reactive oxygen species (ROS) and the imbalance of the antioxidant capacity in organisms. Toxic exposure can induce oxidative stress (Miao et al, 2022; Y. Wang, Zhao et al, 2021), and further oxidative stress triggers various signaling pathways, resulting in disturbed cellular ion homeostasis, inflammatory responses, apoptosis, and necroptosis (Gao et al, 2021; Samimi et al, 2019; H. Zhao et al, 2021), of which, it is worth noting that phosphatidylinositol 3‐kinase/threonine kinase (PI3K/AKT) signaling pathway, toxic exposure‐caused oxidative stress could downregulate PI3K/AKT signaling pathway (L. X. Li et al, 2022), leading to apoptosis through B‐cell lymphoma‐2 (Bcl‐2) signaling pathway, as well as programmed necroptosis via receptor‐interacting protein kinase 1 (RIP1)/RIP3/mixed lineage kinase domain‐like protein (MLKL) signaling pathway (L. Liu et al, 2021; L. Wang et al, 2020b). K. Li et al (2020) exposed chicken to ochratoxin A, finding that ochratoxin A induced renal apoptosis via modulation of oxidative stress and PI3K/AKT signaling pathway, and J. Zhang et al (2020) found that cadmium‐induced oxidative stress in common carp lymphocytes and promoted apoptosis and necrosis through the regulation of the miR‐216a‐PI3K/AKT axis, and pesticides chlorpyrifos induced the apoptosis and necroptosis in L8824 cells through the ROS/PTEN/PI3K/AKT axis (L. Wang et al, 2020b).…”
