Understanding the gutbrain axis and its therapeutic implications for neurodegenerative disorders
This revealed its antioxidative role in reducing oxidative stress and contributing to the inhibition of melanin synthesis by modulating the GSH redox balance ( In vitro , PYC exhibits antioxidant effects during adipogenesis by downregulating the mRNA expression of pro-oxidant enzymes, such as nicotinamide adenine dinucleotide phosphate hydrogen oxidase 4 and glucose-6-phosphate dehydrogenase, while simultaneously upregulating antioxidant enzymes, including Cu/Zn-SOD, Mn-SOD, GPx, and GSH reductase ( ex vivo studies show that PYC acts synergistically with lutein to reduce oxidative stress in porcine retinal homogenates ( In a study using Escherichia coli mutants, PYC induced the expression of key antioxidant enzymes such as MnSOD and CuZnSOD, particularly under oxidative stress, suggesting a potential antioxidative role ( Similarly, PYC mitigated oxidative stress and inflammation induced by titanium dioxide nanoparticles in both murine lung tissue and human airway epithelial cells ( In a randomized clinical trial involving pediatric patients with attention deficit hyperactivity disorder, PYC treatment produced a modest increase in catalase activity, suggesting potential antioxidant effects (Figure 1) in diverse contexts and experimental models
These physiological improvements decrease physical limitations, enabling women to participate more fully in daily activities and reduce the interference of health issues with their physical roles
