286 This indicates that aging is accompanied by ROS accumulation, which is produced by the imbalance of oxidation and antioxidation

Additionally, excess -protein is deposited on the cell membranes, damaging the erythroid precursor cells and ultimately resulting in anemia ( 2.1.3 Abnormal maturation of erythroblasts During the maturation of erythroid cells, alterations in proteins and cytokines are intricately linked to, IE
These findings suggest that MSG may increase cellular oxidative stress by suppressing the antioxidant defense system, and TA may significantly alleviate these adverse effects both at the gene level and in terms of enzyme activity, thus renormalizing the cellular redox level
