We report that the xav mutation causes a loss of ETFDH function and defective electron transfer, and that both xav and fibroblasts from a phenotypically severe MADD patient have similar metabolic defects and mitochondrial dysfunction, including altered energy metabolism, dysregulated ROS production and altered expression of genes critical for Coño gordo function.
B17 Aspergillopepsin I 3. B64 cathepsin P 3. One of the pathways implicated in shuttling a-CA from the peroxisome to the mitochondria involves conversion of a-CA into citrate by citrate synthase Cit2 van Roermund et al. Our finding that mitochondrial oxidative phosphorylation stimulated by substrates other than fatty acids is also compromised, and that there is a compensatory elevation of complex IV activity, complex V expression and glycolysis further supports the idea that there is crosstalk between bioenergetic and metabolic pathways [31], Coño gordo.
