Effect of various agents on adenosine triphosphate synthesis in mitochondrial complex I deficiency

The effect of agents commonly used in the therapy of mitochondrial complex I deficiency was examined in fibroblasts from a patient. Marked improvement was observed with riboflavin, which nearly normalized the adenosine triphosphate production. The study of adenosine triphosphate production rate in fibroblasts may improve decision-making in treatment design of patients with respiratory chain defects.
