C-metabolic flux analysis targeted SG activity on PDK2, thus regulating PDK-PDC-mediated glycolytic metabolism to TCA cycle during mitochondrial OXPHOS damage. The knockdown of PDK2 in the SK-N-SH cells validated that SG could rescue mitochondrial damage via the PDK-PDC axis, promote the MMP level and reduce the mitochondria-dependent apoptosis. Collectively, this study explored the novel therapeutic approach: the PDK-PDC axis for neurological injury and cognitive impairment and uncovered the effect of SG on mitochondrial protection via the PDK-PDC axis and mitochondrial glucose oxidation. The findings indicate that active components ameliorating mitochondrial bioenergetic deficits could be of significant value for neurological disease therapy.
