Effect of taurine deficiency on protein levels of ND6 Cardiomyocytes were exposed to medium containing 5 mM β-alanine for 48 hours. Mitochondria were subjected to Western blot analysis of ND6. (A) Shown is a representative gel of ND6 and succinate dehydrogenase (SDH). (B) Values shown represent means ± S.E.M. of the ND6/SDH ratio of 6-7 preparations. *Significant difference between β-alanine-treated group and Control (p<0.05).
