Oxidative stress, hepatic steatosis, and mitochondrial dysfunction are key pathophysiological features of nonalcoholic fatty liver disease. A conjugated linoleic acid (CLA) mixture of cis9,trans11 (9,11-CLA) and trans10,cis12 (10,12-CLA) isomers enhanced the antioxidant/detoxifying mechanism via the activation of nuclear factor E2-related factor-2 (Nrf2) and improved mitochondrial function, but...

Amphibians globally are in decline, yet there is still a tremendous amount of unrecognized diversity, calling for an acceleration of taxonomic exploration. This process will be greatly facilitated by a DNA barcoding system; however, the mitochondrial population structure of many amphibian species presents numerous challenges to such a standardized, single locus, approach. Here we analyse intra-...

We describe the genetic and molecular analysis of the first non-Mendelian mutants of Chlamydomonas reinhardtii resistant to myxothiazol, an inhibitor of the respiratory cytochrome bc1 complex. Using a set of seven oligonucleotide probes, restriction fragments containing the mitochondrial cytochrome b (cyt b) gene from C. reinhardtii were isolated from a mitochondrial DNA library. This gene is l...

In this study we assessed the relationship between the laboratory and field performance of different isofemale lines of Trichogramma pretiosum Riley. In comparative assays, we used three rare mitochondrial haplotypes as genetic markers of the isofemale lines, and by introgressing these mitochondrial haplotypes into each of 15 genetically different nuclear lines, also tested the assumption that ...

Increased mitochondrial content is a hallmark of exercise-induced skeletal muscle remodeling. For this process, considerable evidence underscores the involvement of transcriptional coactivators in mediating mitochondrial biogenesis. However, our knowledge regarding the role of transcriptional corepressors is lacking. In this study, we assessed the association of the transcriptional corepressor ...

Restriction fragments from purified mitochondrial DNA can be readily detected following rapid end-labeling with [alpha-(3)(2)]nucleoside triphosphates and separation by gel electrophoresis. Mitochondrial DNA from 12 populations of Meloidogyne species was digested with 12 restriction enzymes producing more than 60 restriction fragments for each species. The mitochondrial genome of M. arenaria is...

An acute bout of exercise activates downstream signaling cascades that ultimately result in mitochondrial biogenesis. In addition to inducing mitochondrial synthesis, exercise triggers the removal of damaged cellular material via autophagy and of dysfunctional mitochondria through mitophagy. Here, we investigated the necessity of p53 to the changes that transpire within the muscle upon an impos...

Combining nuclear (nuDNA) and mitochondrial DNA (mtDNA) markers has improved the power of molecular data to test phylogenetic and phylogeographic hypotheses and has highlighted the limitations of studies using only mtDNA markers. In fact, in the past decade, many conflicting geographic patterns between mitochondrial and nuclear genetic markers have been identified (i.e. mito-nuclear discordance...

The common vole Microtus arvalis (Pallas, 1778) is the most widespread species. It has two forms - European form (2n: 46, NF: 84) and Asian obscurus 72). present study aimed to clarify taxonomic status of M. populations distributed in Eastern Turkey, Europe Asia by analysing mitochondrial (CYTB COX1) one nuclear (IRBP) markers. Phylogenetic dendrograms (median-joining networks Bayesian trees) c...

amodiaquine is an antimalarial drug used in the prophylaxis and treatment of this disease. however, hepatotoxicity as a life‑threatening adverse effect is associated with its clinical use. we evaluated amodiaquine-induced toxicity in isolated rat hepatocytes as an in vitro model for studying drug‑induced hepatotoxicity. this study attempts to investigate the protective effects of taurine and n-...
