Effect of uric acid on mitochondrial function and oxidative stress in hepatocytes
Authors: Y. Yang, Y. Zhou, S. Cheng, J.L. Sun, H. Yao and L. Ma
Here, we investigated the effect of uric acid (UA) on hepatocyte mitochondria. Hepatocytes cultured in vitro were treated with varying concentrations of UA. The change in apoptotic activity was detected by flow cytometry. The DNA damage index 8-hydroxy-deoxy-guanosine (8-OHdG) and mitochondrial function indices succinate dehyd.. Read More»

Complete mitochondrial genome sequence and gene organization of Chinese indigenous chickens with phylogenetic considerations
Authors: F.P. Zhao, H.Y. Fan, G.H. Li and B.K. Zhang
In this study, we sequenced the complete mitochondrial DNA of Chinese indigenous Jinhu Black-bone and Rugao chickens. The two chicken mitochondrial genomes were deposited in GenBank under accession Nos. KP742951 and KR347464, respectively. The complete mitochondrial genomes of Jinhu Black-bone and Rugao chickens were sequenced.. Read More»

Complete mitochondrial genome of the Liuyang black goat and its phylogenetic relationship with other Caprinae
Authors: S. Chen, H.M. Ma, G.S. Chen and L.Y. Wang
In this study, the complete mitochondrial genome sequence of the Liuyang black goat was investigated, and phylogenetic relationships between the Liuyang black goat and other species of Caprinae were analyzed. The total length of the mitochondrial genome was 16,715 bp, which consisted of 33.50% A, 27.27% T, 25.98% C, and 13.25%.. Read More»

Deciphering the spectrum of somatic mutations in the entire mitochondrial DNA genome
Authors: X.Z. Chen, Y. Fang, Y.H. Shi, J.H. Cui, L.Y. Li, Y.C. Xu and B. Ling
The mitochondrion is a crucial intracellular organelle responsible for regulating cellular energy metabolism, producing free radicals, initiating and executing the apoptotic pathways. Previous studies have shown that somatic mutations in mitochondrial DNA are associated with various tumors, which may be involved during carcinogenesis and tumor progression.. Read More»

Less Ã?Â?mtDNA4977 than normal in various types of tumors suggests that cancer cells are essentially free of this mutation
Authors: Maria Angela C. Dani, Sergio U. Dani, Silmara P.G. Lima, Alfredo Martinez, Benedito M. Rossi, Fernando Soares, Marco A. Zago and Andrew J.G. Simpson
Levels of mtDNA4977 deletions (DmtDNA4977) have been found to be lower in tumors than in adjacent non-tumoral tissues. In 87 cancer patients, DmtDNA4977 was detected by multiplex polymerase chain reaction (PCR) amplification in 43 (49%) of the tumors and in 74 (85%) of the samples of non-tumoral tissues that were adjacent to t..

Evaluation of a method for high yield purification of largely intact mitochondrial DNA from human placentae
Authors: Sergio U. Dani, Alessandra Cristina Gomes-Ruiz, Maria Angela C. Dani
We developed, and quantitatively and qualitatively evaluated an easily reproducible method for high yield purification of mitochondrial DNA (mtDNA) from human placentae by mechanical tissue disruption, differential centrifugation of mitochondria, enzymatic digestion, phenol extraction and ethanol precipitation. Average mtDNA y.. Read More»
