Abstract

Mitochondria are cellular power plants which any defect in their proper function might lead to deleterious consequences. Mitochondrial dysfunction has been identified as a pivotal mechanism involved in the pathogenesis of xenobiotics-induced toxicity as well as in the etiology of several diseases. In this context, protecting mitochondria could play a crucial role in the development of therapeutic strategies against a wide range of clinical complications. The current study was designed to examine the direct effects of some amino acids with previously-reported cytoprotective background on cellular mitochondria. Isolated mitochondria were incubated with taurine, proline, histidine, glycine, and betaine and several mitochondrial indices including mitochondrial depolarization, swelling and permeabilization, dehydrogenases activity, and ATP content were monitored. Calcium (Ca2+; 200 ?M) was used as the stressor. It was found that the investigated amino acids significantly preserved mitochondrial function in a Ca2+ overloaded environment as revealed by significantly higher mitochondrial membrane potential, dehydrogenases activity, and ATP content in amino acid-treated groups. Moreover, mitochondrial swelling and permeabilization were significantly blunted after amino acid treatment. The data obtained from this study might provide essential and robust clues to new and safe therapeutic interventions against mitochondria-linked disorders.

Graphical abstract

The mitochondrial protecting properties of the amino acids could be mediated through a variety of mechanisms. The mitochondria protecting amino acids could be clinically applicable to a wide range of mitochondrial-linked disorders. mPT: Mitochondria permeability transition; CAT: Catalase; SOD: Superoxide dismutase; Ca2+: Calcium ion.
