PACAP protects cerebellar granule neurons against oxidative stress-induced apoptosis.
Oxidative stress, resulting from accumulation of reactive oxygen species, plays a critical role in neuronal cell death associated with neurodegenerative diseases and stroke. In the present study, we have investigated the potential neuroprotective effect of pituitary adenylate cyclase-activating polypeptide (PACAP) on oxidative stress-induced apoptosis. Incubation of cerebellar granule cells wit...
متن کاملPhosphorylation of c-Jun is necessary for apoptosis induced by survival signal withdrawal in cerebellar granule neurons.
Cerebellar granule neurons die by apoptosis when deprived of survival signals. This death can be blocked by inhibitors of transcription or protein synthesis, suggesting that new gene expression is required. Here we show that c-jun mRNA and protein levels increase rapidly after survival signal withdrawal and that transfection of the neurons with an expression vector for a c-Jun dominant negative...
متن کاملBafilomycin A1 inhibits chloroquine-induced death of cerebellar granule neurons.
Treatment of cells with the macrolide antibiotic bafilomycin A1, an inhibitor of vacuolar (V)-ATPase, or with the lysosomotropic agent chloroquine, has been shown to pharmacologically inhibit autophagy as evidenced by an accumulation of autophagosomes, which in turn causes Bax-dependent apoptosis. However, bafilomycin A1 has also been reported to inhibit chloroquine-induced apoptosis, suggestin...
متن کاملScreening seven Iranian medicinal plants for protective effects against β-Amyloid-induced cytotoxicity in cultured cerebellar granule neurons
Background and objectives: Alzheimer's disease (AD) as a neurodegenerative disorder is the most common form of dementia in the elderly. According to the amyloid hypothesis, accumulation of amyloid beta (Aβ) plaques, which are mostly constituted of Aβ peptide aggregates, triggers pathological cascades that lead to neuronal cell death. Thus, modulation of Aβ toxicity is the hopef...
متن کاملMitofusin 2 protects cerebellar granule neurons against injury-induced cell death.
Of the GTPases involved in the regulation of the fusion machinery, mitofusin 2 (Mfn2) plays an important role in the nervous system as point mutations of this isoform are associated with Charcot Marie Tooth neuropathy. Here, we investigate whether Mfn2 plays a role in the regulation of neuronal injury. We first examine mitochondrial dynamics following different modes of injury in cerebellar gra...
