• The bioenergetic and antioxidant status of neurons is controlled by continuous degradation of a key glycolytic enzyme by APC/C-Cdh1.

  Neurons are known to have a lower glycolytic rate than astrocytes and when stressed they are unable to upregulate glycolysis because of low Pfkfb3 (6-…

• Nitric oxide switches on glycolysis through the AMP protein kinase and 6-phosphofructo-2-kinase pathway.

  After inhibition of cytochrome c oxidase by nitric oxide, astrocytes maintain energy production by upregulating glycolysis--a response which does not …

• Bilirubin selectively inhibits cytochrome c oxidase activity and induces apoptosis in immature cortical neurons. Assessment of the protective effects of glycoursodeoxycholic acid.

  Abstract High levels of unconjugated bilirubin (UCB) may initiate encephalopathy in neonatal life, mainly in premature infants. The molecular mechanis…

• Inhibition of PTEN by peroxynitrite activates the phosphoinositide-3-kinase/Akt neuroprotective signaling pathway.

  Peroxynitrite is usually considered as a neurotoxic nitric oxide-derivative. However, an increasing body of evidence suggests that, at low concentrati…

• Modulation of astroglial energy metabolism by nitric oxide.

  Activated astroglial cells produce large amounts of nitric oxide (NO) which, through the binding to soluble guanylyl cyclase, rapidly increases cyclic…

• Increased mitochondrial respiration maintains the mitochondrial membrane potential and promotes survival of cerebellar neurons in an endogenous model of glutamate receptor activation.

  It is thought that the combination of extracellular glutamate accumulation and mitochondrial damage is involved in neuronal death associated with brai…
