This study used β-D-glucuronidase activity (GLUC) with microbial source tracking (MST) markers: human, bovine, porcine mitochondrial DNA markers (mtDNA) and human-associated Bacteroidales HF183 and chemical source tracking (CST) markers including caffeine, carbamazepine, theophylline and acetaminophen, pathogens (Giardia, Cryptosporidium, adenovirus, ...
The clinical sample types generally include fresh or frozen tissue that often yield high quality DNA and samples that often yield low quantity and/or compromised quality DNA like FFPE (formalin-fixed paraffin-embedded) tissue, decalcified FFPE tissue, bone marrow trephines, smears, and fine needle aspirates (FNA), plasma, and circulating tumor cells. Some studies ...
Mitochondrial DNA (mtDNA) encodes only 13 mitochondrial proteins, which are transcribed and translated within the mitochondria and become important protein components of the respiratory chain complex. mtDNA also encodes 2 ribosomal RNAs and 22 transfer RNAs, which can ensure the smooth expression of the respiratory chain complex proteins it ...
The present study was undertaken to evaluate the protective effect of selenium on arsenic trioxide (As2O3)–induced cytotoxicity, DNA damage, and apoptosis. N‐Acetylcysteine (NAC), a free radical scavenger, was used to determine the involvement of reactive oxygen species (ROS) in As2O3‐induced DNA damage and apoptosis. ...
Here we report that 2-deoxyribonolactone (dL), a major type of oxidized abasic site, inhibits replication by mitochondrial DNA (mtDNA) polymerase and interferes with SP-BER by covalently trapping polymerase during attempted dL excision. ...
The intraspecific genetic diversity of the kelp Undaria pinnatifida (Harvey) Suringar (Laminariales, Phaeophyceae) was investigated using DNA sequences of the mitochondrial cytochrome oxidase subunit 3 (cox3) gene and internal transcribed spacer 1 (ITS1) of nuclear ribosomal DNA in plants collected from 21 localities along the Japanese coast ...
This species currently has a highly fragmented distribution inhabiting a mosaic of habitats. This project uses mitochondrial DNA (mtDNA) and microsatellite data to determine levels of genetic diversity, population structure and evolutionary history, which can aid wildlife managers in setting priorities and determining management strategies. ...
A region of 826 bp that is unlikely to code for a protein, ribosomal RNA, or transfer RNA was identified between the cytochrome b and NADH–ubiquinone oxidoreductase chain 2 loci in the mitochondrial DNA of the scleractinian reef coral Galaxea fascicularis. Nucleotide sequences were determined in a part (625 bp) of this intergenic region in 95 individuals ...
The genetic differentiation of the European lobster (Homarus gammarus) was investigated in 3,283 individuals from 44 population samples throughout its geographical distribution (Norway to Greece) by means of polymerase chain reaction restriction fragment length polymorphism analysis of a 3-kb mitochondrial DNA segment. Ninety composite haplotypes were revealed ...
The distribution and genetic structure of many marine invertebrates in the North Atlantic have been influenced by the Pleistocene glaciation, which caused local extinctions followed by recolonization in warmer periods. Mitochondrial DNA markers are typically used to reconstruct species histories. Here, two mitochondrial markers [16S rDNA and ...
In this study we used two molecular genetic techniques—protein electrophoresis of nuclear DNA loci, and restriction fragment length polymorphism analysis of the mitochondrial DNA (mtDNA)—to assess this species population genetic structure in the eastern (coastal waters off Gabon and Sierra Leone, Africa) and western (coastal waters off Florida, ...
