Molecular and biochemical evidence on the protection of cardiomyocytes from phosphine-induced oxidative stress, mitochondrial dysfunction and apoptosis by acetyl-L-carnitine. ENVIRONMENTAL TOXICOLOGY AND PHARMACOLOGY 2016; 42:30-37. [PMID: 26773361 DOI: 10.1016/j.etap.2015.12.019] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/14/2015] [Revised: 12/22/2015] [Accepted: 12/26/2015] [Indexed: 06/05/2023]
Abstract
The aim of the present study was to investigate the efficacy of acetyl-L-carnitine (ALCAR) on pathologic changes of mitochondrial respiratory chain activity, ATP production, oxidative stress, and cellular apoptosis/necrosis induced by aluminum phosphide (AlP) poisoning. The study groups included: the Sham that received almond oil only; the AlP that received oral LD50 dose of aluminum; the AC-100, AC-200, and AC-300 which received concurrent oral LD50 dose of AlP and single 100, 200, and 300 mg/kg of ALCAR by intraperitoneal injection. After 24 h, the rats were sacrificed; the heart and blood sample were taken for measurement of biochemical and mitochondrial factors. The results specified that ALCAR significantly attenuated the oxidative stress (elevated ROS and plasma iron levels) caused by AlP poisoning. ALCAR also increased the activity of cytochrome oxidase, which in turn amplified ATP production. Furthermore, flow cytometric assays and caspase activity indicated that ALCAR prohibited AlP-induced apoptosis in cardiomyocytes.

Abstract
1-Methyl-4-phenylpyridinium ion (MPP+), an inhibitor of mitochondrial complex I, has been widely used as a neurotoxin because it elicits a severe Parkinson's disease-like syndrome with an elevation of intracellular reactive oxygen species (ROS) and apoptosis. L-carnitine plays an integral role in attenuating the brain injury associated with mitochondrial neurodegenerative disorders. The present study investigates the effects of L-carnitine against the toxicity of MPP+ in rat forebrain primary cultures. Cells in culture were treated for 24 h with 100, 250, 500 and 1000 microM MPP+ alone or co-incubated with L-carnitine. MPP+ produced a dose-related increase in DNA fragmentation as measured by cell death ELISA (enzyme-linked immunosorbent assay), an increase in the number of TUNEL (terminal dUTP nick-end labeling)-positive cells and a reduction in the mitochondrial metabolism of 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT). No significant effect was observed with the release of lactate dehydrogenase (LDH), indicating that cell death presumably occurred via apoptotic mechanisms. Co-incubation of MPP+ with L-carnitine significantly reduced MPP+-induced apoptosis. Western blot analyses showed that neurotoxic concentrations of MPP+ decreased the ratio of BCL-X(L) to Bax and decreased the protein levels of polysialic acid neural cell adhesion molecules (PSA-NCAM), a neuron specific marker. L-carnitine blocked these effects of MPP+ suggesting its potential therapeutic utility in degenerative disorders such as Parkinson's disease, Alzheimer's disease, ornithine transcarbamylase deficiency and other mitochondrial diseases.

Abstract
The development, growth and regeneration of nerve cells remain an unresolved issue. The up-to-date reported brain repair mechanisms are numerous and evidence suggests that, apart from the required trophism, tropism, microenvironment and specificity of the brain, a plethora of chemical, physiological and immunological compounds can contribute to such events. Among these compounds, we concentrated our interest on L-carnitine (L-Cn), which regulates the beta-oxidation of long chain fatty acids necessary for brain development, myelinization and growth. In contrast to fetal brain cells that grow easily in culture, adult brain cells show limited neurogenesis. Here, using adult brain cells from experimental mice, we show that although L-Cn does not improve their proliferative activity in short-term cultures, it accelerates the growth and differentiation of neurons, astrocytes, oligodendrocytes and ependymal cells from neurospheres in long-term cultures. Thus, the formation of a confluent neural network requires a 2-month period in culture. These observations provide new insights for in vivo use of L-Cn to support brain cell development in cases of injury or brain degenerative diseases.
