Novel targets for valproic acid: up‐regulation of melatonin receptors and neurotrophic factors in C6 glioma cells

Valproic acid (VPA) is a potent anti-epileptic and effective mood stabilizer. It is known that VPA enhances central GABAergic activity and activates the mitogen-activated protein kinase-extracellular signal-regulated kinase (MAPK-ERK) pathway. It can also inhibit various isoforms of the enzyme, histone deacetylase (HDAC), which is associated with modulation of gene transcription. Recent in vivo studies indicate a neuroprotective role for VPA, …
