Reduced PDH, aconitase activities and complex I activity in mutant PANK2 fibroblasts. Control (C), P1 and P3 fibroblasts were treated with 500 μM pantothenate for 20 days. a, b PDH activity in whole cellular extracts was determined as described in Material and Methods. c, d Cytosolic and mitochondrial aconitase activity in whole cellular extracts was determined as described in Material and Methods. e, f Mitochondrial complex I activity in whole cellular extracts was determined as described in Material and Methods. Data represent the mean ± SD of three separate experiments. *p < 0.01 between PKAN patients and controls; ap < 0.01 between untreated and treated cells
