    Cell Signaling Technology Inc rabbit anti p300
    Flow diagram depicting low acetyl-CoA levels as a central metabolic change that connects reduced expression of metabolic genes to mitochondrial ATP production impairment. From left, altered <t>p300/CBP</t> activity, which may be due to sequestration and depletion by the mutant AR (40), leads to reduced H3K27ac. This in turn contributes to repression of ETC and metabolic genes. Repression of these genes perturbs compensatory metabolic pathways, which results in insufficient production of acetyl-CoA. Acetyl-CoA is a common substrate for both the ETC function and p300/CBP HAT activity. Low acetyl-CoA (substrate) contributes to low ATP production and mitochondrial dysfunction. In parallel, when the energy demands of the cell increase, mitochondria respond by consuming more acetyl-CoA (substrate). The reduction of acetyl-CoA contributes to repression of ETC and metabolic genes through impaired p300/CBP acetylation.
