A Critical Reassessment of the Role of Mitochondria in Tumorigenesis
(Plos, 2005)Background Mitochondrial DNA (mtDNA) is being analyzed by an increasing number of laboratories in order to investigate its potential role as an active marker of tumorigenesis in various types of cancer. Here we question ... -
Contenido de mercurio en conservas de mejillones, berberechos y navajas comercializados en Galicia (España)
(Taylor & Francis, 2007)Molluscs accumulate heavy metals and impose health hazard to consumers. Mercury is considered as a metal not essential and very toxic. Concentrations of mercury were determined for tinned mussels, common cockle and razors ... -
Distilling Artificial Recombinants from Large Sets of Complete mtDNA Genomes
(PLOS, 2008)Background: Large-scale genome sequencing poses enormous problems to the logistics of laboratory work and data handling. When numerous fragments of different genomes are PCR amplified and sequenced in a laboratory, there ... -
Retinoblastoma Loss Modulates DNA Damage Response Favoring Tumor Progression
(PLOS, 2008)Senescence is one of the main barriers against tumor progression. Oncogenic signals in primary cells result in oncogeneinduced senescence (OIS), crucial for protection against cancer development. It has been described in ... -
Estimating Haplotype Frequency and Coverage of Databases
(Plos, 2008)A variety of forensic, population, and disease studies are based on haploid DNA (e.g. mitochondrial DNA or Y-chromosome data). For any set of genetic markers databases of conventional size will normally contain only a ... -
SPSmart: adapting population based SNP genotype databases for fast and comprehensive web access
(BMC, 2008)Background: In the last five years large online resources of human variability have appeared, notably HapMap, Perlegen and the CEPH foundation. These databases of genotypes with population information act as catalogues ... -
Genomic degradation of a young Y chromosome in Drosophila miranda
(BMC, 2008)Background: Y chromosomes are derived from ordinary autosomes and degenerate because of a lack of recombination. Well-studied Y chromosomes only have few of their original genes left and contain little information about ... -
RAS gene polymorphisms, classical risk factors and the advent of coronary artery disease in the Portuguese population
(BMC, 2008)Background: Several polymorphisms within the renin-angiotensin system cluster of genes have been associated with the advent of coronary artery disease (CAD) or related pathologies. We investigated the distribution of 5 ... -
Minisequencing mitochondrial DNA pathogenic mutations
(BMC, 2008)Background: There are a number of well-known mutations responsible of common mitochondrial DNA (mtDNA) diseases. In order to overcome technical problems related to the analysis of complete mtDNA genomes, a variety of ... -
Genetic origin, admixture, and asymmetry in maternal and paternal human lineages in Cuba
(BMC, 2008)Background: Before the arrival of Europeans to Cuba, the island was inhabited by two Native American groups, the Tainos and the Ciboneys. Most of the present archaeological, linguistic and ancient DNA evidence indicates ... -
The Phylogeny of the Four Pan-American MtDNA Haplogroups: Implications for Evolutionary and Disease Studies
(Plos, 2008)Only a limited number of complete mitochondrial genome sequences belonging to Native American haplogroups were available until recently, which left America as the continent with the least amount of information about ... -
Timing and deciphering mitochondrial DNA macro-haplogroup R0 variability in Central Europe and Middle East
(BMC, 2008)Background: Nearly half of the West Eurasian assemblage of human mitochondrial DNA (mtDNA) is fractioned into numerous sub-lineages of the predominant haplogroup (hg) R0. Several hypotheses have been proposed on the ... -
New Population and Phylogenetic Features of the Internal Variation within Mitochondrial DNA Macro-Haplogroup R0
(PLOS, 2009)Background: R0 embraces the most common mitochondrial DNA (mtDNA) lineage in West Eurasia, namely, haplogroup H (,40%). R0 sub-lineages are badly defined in the control region and therefore, the analysis of diagnostic ... -
Acumulación de selenio en setas silvestres comestibles: captación y toxicidad Selenium accumulation in wild edible mushrooms: uptake and toxicity
(Taylor & Francis, 2009)Los hongos acumulan selenio, metal considerado nutricionalmente oligoelemento, pero nocivo para la salud del consumidor en dosis excesivas. Se estudió el contenido de selenio en setas silvestres comestibles, teniendo en ... -
Investigating the Role of Mitochondrial Haplogroups in Genetic Predisposition to Meningococcal Disease
(PLOS, 2009)Background and Aims: Meningococcal disease remains one of the most important infectious causes of death in industrialized countries. The highly diverse clinical presentation and prognosis of Neisseria meningitidis infections ... -
Ancestry Analysis in the 11-M Madrid Bomb Attack Investigation
(PLOS, 2009)The 11-M Madrid commuter train bombings of 2004 constituted the second biggest terrorist attack to occur in Europe after Lockerbie, while the subsequent investigation became the most complex and wide-ranging forensic case ... -
Mitochondrial Echoes of First Settlement and Genetic Continuity in El Salvador
(Plos, 2009)Background: From Paleo-Indian times to recent historical episodes, the Mesoamerican isthmus played an important role in the distribution and patterns of variability all around the double American continent. However, the ... -
High Mitochondrial DNA Stability in B-Cell Chronic Lymphocytic Leukemia
(PLOS, 2009)Background: Chronic Lymphocytic Leukemia (CLL) leads to progressive accumulation of lymphocytes in the blood, bone marrow, and lymphatic tissues. Previous findings have suggested that the mtDNA could play an important ... -
Molecular analysis of the APC and MUTYH genes in Galician and Catalonian FAP families: a different spectrum of mutations?
(BMC, 2009)Background: Familial adenomatous polyposis (FAP) is an autosomal dominant-inherited colorectal cancer syndrome, caused by germline mutations in the APC gene. Recently, biallelic mutations in MUTYH have also been identified ... -
Contamination and sample mix-up can best explain some patterns of mtDNA instabilities in buccal cells and oral squamous cell carcinoma
(BMC, 2009)The study of somatic DNA instabilities constitutes a debatable topic because different causes can lead to seeming DNA alteration patterns between different cells or tissues from the same individual. Carcinogenesis or the ...
