Cadmium toxicity has been associated with learning disabilities and Parkinsonian symptoms in humans. We have previously shown that cultured oligodendrocytes are directly damaged by cadmium exposure. Here, we characterized the molecular mechanisms underlying cadmium-induced cell death in oligodendrocyte progenitors (OLP). Cadmium caused a concentration-dependent decrease in cell viability as assessed...
BAK/BAX-mediated mitochondrial outer-membrane permeabilization (MOMP) drives cell death during development and tissue homeostasis from zebrafish to humans. In most cancers, this pathway is inhibited by BCL-2 family antiapoptotic members, which bind and block the action of proapoptotic BCL proteins. We report the 1.5 Å crystal structure of calpain-proteolysed BAK, cBAK, to reveal a zinc binding site...
