    Summary
    Growth hormone releasing peptide-6 reversed glutamate-induced cell death by decreasing activation of caspases 9 and 7 and poly(ADP-ribose) polymerase fragmentation.
    2 context sentences
    Summary · context
    Glutamate increased activation of caspase 9 followed by cleavage of caspase 7, which in turn fragmented poly(ADP-ribose) polymerase, terminating in cell death in both the hypothalamus and cerebellum.
    Summary · context
    Because abnormally high concentrations of glutamate can lead to overexcitation of neurones leading to cell damage and/or death, we investigated whether administration of growth hormone releasing peptide-6 attenuates monosodium glutamate-induced apoptosis in the rat hypothalamus and cerebellum.
  2. 02AnimalAnimal study (in vivo)Mechanism

    In rat hypothalamus and cerebellum, GHRP‑6 decreased glutamate-induced caspase 9 activation.
