Original Source: Ethyl pyruvate stabilizes hypoxia-inducible factor 1 alpha via stimulation of the TCA cycle.
Ethyl pyruvate is a simple derivative of the endogenous metabolite pyruvate. Pyruvate is the starting substrate for the tricarboxylic acid (TCA) cycle and plays a central role in intermediary metabolism. The present study was to determine whether ethyl pyruvate affects the expression of hypoxia-inducible factor 1 alpha (HIF-1alpha) and to explore the mechanism of HIF-1alpha regulation. We found that ethyl pyruvate increased HIF-1alpha stability via inhibition of pVHL-mediated degradation. Furthermore, ethyl...
