For instance, FoxO factors induce the expression of FoxP3 transcription factor which determines the ultimate properties of the Treg cell lineage [68]

Despite an increase in urine calcium concentration, the relative saturation of calcium oxalate decreased due to citrate chelation of calcium and the concentration of undissociated uric acid decreased due to the significant increase in urine pH (23)

Non-Enzymatic Antioxidants Endogenous antioxidants fall into two major categories: Enzymatic Antioxidants: Protein-based molecules that catalyze specific reactions to neutralize free radicals Require cofactors (often minerals like selenium, copper, zinc, and manganese) Can be recycled and reused, allowing continued antioxidant activity Function within specific cellular compartments where they're most needed Regulated by gene expression and can be upregulated in response to oxidative stress Non-Enzymatic Antioxidants: Small molecules that directly interact with free radicals Include compounds like glutathione, uric acid, and coenzyme Q10 Often become oxidized themselves in the process of neutralizing free radicals May require vitamin cofactors or other nutrients for synthesis Distributed throughout various tissues and body fluids Both types work together in a coordinated network to provide comprehensive protection against oxidative damage
