Relationship Between Expression of Voltage-Dependent Anion Channel (VDAC) Isoforms and Type of Hexokinase Binding Sites on Brain Mitochondria

Abstract: Voltage-dependent anion channels (VDAC) are pore-forming proteins found in the outer mitochondrial membrane of eukaryotes. VDACs are known to play an essential role in cellular metabolism and in early stages of apoptosis. In mammals, three VDAC isoforms have been identified. A proteomic approach was exploited to study the expression of VDAC isoforms in rat, bovine, and chicken brain mitochondria. Given the importance of mitochondrially bound hexokinase in regulation of aerobic glycolysis in brain, we studied t… Show more

“…hVDAC-2 suppresses apoptosis by specifically binding to the proapoptotic protein BAK and inhibiting BAK-mediated mitochondrial apoptosis (15). hVDAC-2 levels are also known to be elevated in bovine brain mitochondria (20), as well as in Alzheimer disease (7,21). This protein has also been shown to bind erastin, which subsequently modulates VDAC function, leading to oxidative cell death, using a nonapoptotic mechanism (22).…”

“…Procuramos identiϐicar se as expressões diferenciadas da VDAC1 e VDAC2 veriϐicadas nos cérebros murino, aviar e bovino, publicadas anteriormente pelo Laboratório (Poleti et al 2010), estão associadas a diferenças nos interactomas dessas proteínas nesses cérebros. Na Figura 2 estão esquematizados géis nativos para as amostras mitocondriais aviar, bovina e murina e o padrão de peso molecular utilizado para o cálculo dos pesos dos complexos realizado pelo software.…”

“…Estudo anterior do laborató-rio, mostrou que a expressão diferenciada das isoformas da VDAC nas espécies aviar, bovina e murina estão relacionadas às diferenças no metabolismo energético neuronal de cada espécie (Poleti et al 2010). Paralelamente, Crawford (1970) reportou que aves epiléticas exibiram crises tônico-clônicas generalizadas em resposta à fotoestimulação intermitente (FEI) e acústica.…”
