In vivo experiments confirmed that the MPO/HOCl signaling pathway was significantly activated in the plasma and neurons of SOD1 G93A transgenic mice, which upregulated Caspase-3 expression, downregulated GPX4 and NQO1 expression, significantly elevated plasma MDA levels, promoted neuronal apoptosis, ferroptosis, and lipid peroxidation, and reduced motor performance in mice (Peng et al., 2022)
In inflammatory contexts, NF-kB suppression is particularly relevant because chronic NF-kB activation drives the disruption of tight junction proteins (claudin, occludin) that characterizes increased intestinal permeability in colitis models
Recent studies have revealed that dysregulation of mitochondrial dynamicsincluding impaired mitophagy, imbalances in mitochondrial fusion and fission, and defects in mitochondrial biogenesisis closely associated with CRC initiation, progression, and resistance to therapy [46]
