Abstract:
The protective potential of ethyl pyruvate (EP) on neuron has been investigated previously. This study was intended to investigate the effects of EP on the severity of oxygen-glucose deprivation (OGD)-induced injury in neural-like PC12 cells. PC12 cells were exposed to OGD condition with or without EP treatment. Then, cell viability, apoptosis, and the expressions of neurotrophic factors were detected. Further, Sprague-Dawley rats were intravenously administered with 5mg/kg EP for 14 days post-middle cerebral artery occlusion (MCAO). The effects of EP on the infarct volumes and neurological functions of MCAO rats were then assessed. Result showed that EP alleviated OGD-diminished cells viability, OGD-induced apoptosis, and OGD-reduced expressions of brain-derived neurotrophic factor (BDNF), nerve growth factor (NGF) and Nestin in PC-12 cells. EP blocked OGD-activated the Notch1 and nuclear factor Kappa B (NF-κB) signaling pathways in PC12 cells. Besides, in vivo data demonstrated that EP treatment decreased infarct volume and mNSS score, and increased the time spent on the rota-rod apparatus of MCAO rats. To conclude, EP protected neural-like PC12 cells from cerebral ischemia-reperfusion injury by suppressing apoptosis and promoting neural restoration. Notch1 and NF-κB pathway might implicated in the functions of EP on neuron.

01:20Fates of Pyruvate
In aerobic organisms, pyruvate is metabolized via the citric acid cycle to produce reduced coenzymes NADH and FADH2. These coenzymes are then oxidized in the electron transport chain to produce ATP and, in the process, regenerate the NAD+ and FAD. As seen in some cell types and organisms, fermentation...
01:15Pyruvate Oxidation
First, the enzyme pyruvate dehydrogenase removes the carboxyl group from pyruvate and releases it as carbon dioxide. The stripped molecule is then oxidized and releases electrons, which are then picked up by NAD+...

00:56What is Glycolysis?
Cells make energy by breaking down macromolecules. Cellular respiration is the biochemical process that converts "food energy" (from the chemical bonds of macromolecules) into chemical energy in the form of adenosine triphosphate (ATP). The first step of this tightly regulated and intricate process is glycolysis. The word glycolysis originates from the Latin glyco (sugar) and lysis (breakdown). Glycolysis serves two main intracellular functions: generating ATP and generating...
