Quantitative proteomics analysis demonstrated T89 improved metabolic disorders by regulating expression of Eno1, Mcee, Bdh1, Ces1c, Apoc2, Decr1, Acaa2, Cbr4, ND2, Cox6a, Cox17, ATP5g, and ATP5j, further restoring mitochondrial ETC complex activities and attenuating ISO-caused oxidative stress damage and energy depletion. The gene discussed is MT-ND2; the disease is metabolic disease.
