Mitochondrial reactive oxygen species mediate cellular signaling pathways involved in psoriasis, such as proliferation, apoptosis, and inflammation, leading to oxidative stress, exacerbating inflammation and tissue damage if dysregulated. This review explores oxidative stress biomarkers and parameters in psoriasis, including myeloperoxidase, paraoxonase, sirtuins, superoxide dismutase, catalase, malondialdehyde, oxidative stress index, total oxidant status, and total antioxidant status. These markers provide insights into disease mechanisms and potential diagnostic and therapeutic targets. Modulating mitochondrial reactive oxygen species levels and enhancing antioxidant defenses can alleviate inflammation and oxidative damage, improving patient outcomes. Natural antioxidants like quercetin, curcumin, gingerol, resveratrol, and other antioxidants show promise as complementary treatments targeting oxidative stress and mitochondrial dysfunction.

PON1 has been extensively studied in relation to Alzheimer's Disease (AD), but the role of PON3 remains unknown. To fill this knowledge gap, the study analyzed PON3 protein levels and PON1-arylesterase activity in 99 AD patients, 100 patients with mild cognitive impairment (MCI), and 79 cognitively normal controls. The results showed that serum PON3 levels remained unchanged across all groups. In contrast, serum arylesterase activity was significantly reduced in both AD and MCI patients compared to controls (<i>p</i> < 0.001 for both comparisons).

In this study, the effect of heat stress on the cardiac function of <i>C. farreri</i> was investigated during the continuous 30-day heat stress at 27 °C. The results showed the heart rate of scallops increased due to stress in the initial phase of high temperature exposure, peaking at 12 h, and then gradually recovered, indicating an acclimatization at the end of the experiment. In addition, the levels of catalase (CAT), superoxide dismutase (SOD), and total antioxidant capacity (T-AOC) exhibited an initial increase followed by recovery in response to heat stress. Furthermore, transcriptome analysis of the heart identified 3541 differentially expressed genes (DEGs) in response to heat stress. Subsequent GO and KEGG enrichment analysis showed that these genes were primarily related to signal transduction and oxidative stress, such as the phosphatidylinositol signaling system, regulation of actin cytoskeleton, MAPK signaling pathway, FoxO signaling pathway, etc. In addition, two modules were identified as significant responsive modules according to the weighted gene co-expression network analysis (WGCNA). The upregulation of key enzymes within the base excision repair and gap junction pathways indicated that the heart of <i>C. farreri</i> under heat stress enhanced DNA repair and maintained cellular integrity. In addition, the variable expression of essential signaling molecules and cytoskeletal regulators suggested that the heart of <i>C. farreri</i> modulated cardiomyocyte contraction, intracellular signaling, and heart rate through complex regulation of phosphorylation and calcium dynamics in response to heat stress.
