Antioxidant enzymes form the first line of defense against free radicals in organisms. Their regulation depends mainly on the oxidant status of the cell, given that oxidants are their principal modulators. However, other factors have been reported to increase antioxidant enzyme activity and/or gene expression. During the last decade, the antioxidant(More)
To investigate the clinical value of somatic TP53 mutations in breast cancer, we assembled clinical and molecular data on 1,794 women with primary breast cancer with long-term follow-up and whose tumor has been screened for mutation in exons 5 to 8 of TP53 by gene sequencing. TP53 mutations were more frequent in tumors of ductal and medullar types,(More)
BACKGROUND Heart failure (HF) is a major health problem in developed countries. HF is a progressive, lethal disorder, even with adequate treatment. There exists a vicious circle in the pathophysiology of HF that perpetuates and magnifies the problem. Concomitant fluid accumulation may worsen the congestive HF, it is responsible for numerous hospitalizations(More)
Inflammation is a complex phenomenon involving multiple cellular and molecular interactions which must be tightly regulated. Cyclooxygenase-2 (COX) is the key enzyme that catalyzes the two sequential steps in the biosynthesis of PGs from arachidonic acid. The inducible isoform of COX, namely COX-2, plays a critical role in the inflammatory response and its(More)
Genetic markers provide a useful tool toestimate pairwise coancestry betweenindividuals in the absence of a known pedigree. Inthe present work 62 pigs from two relatedstrains of Iberian breed, Guadyerbas andTorbiscal, belonging to a conservationprogramme with completely known pedigrees since1945, have been genotyped for 49microsatellites. Four coefficients(More)
The use of molecular markers is an accessible technology with wide applications. One of them is the construction of genetic maps and the location of quantitative trait loci (QTL). The pig genetic map has allowed carrying out QTL analysis with chromosome or genome scan on F2 populations coming from crosses of divergent breeds. Many of these experiments have(More)
OBJECTIVE To estimate the risk and probability of heterosexual transmission of HIV-1 from infected people taking combined antiretroviral treatment. DESIGN Cross sectional and prospective cohort studies. SETTING HIV clinic in Madrid, Spain. PARTICIPANTS Stable heterosexual couples with one partner with HIV-1 infection (index partner) and the other(More)
The aim of this study was to investigate chromosomal regions affecting the number of teats in pigs and possible epistatic interactions between the identified quantitative trait loci (QTL). An experimental F2 cross between Iberian and Chinese Meishan lines was used for this purpose. A genomic scan was conducted with 117 markers covering the 18 porcine(More)
DNA amplification at band q13 of chromosome 11 is common in breast cancer, and CCND1 and EMS1 remain the strongest candidate genes. However, amplification patterns are consistent with the existence of four cores of amplification, suggesting the involvement of additional genes. Here we present evidence strongly suggesting the involvement of the recently(More)
DNA amplification is frequent in breast cancer and has been associated with specific clinicopathological parameters and/or worsened course of the disease. In the present work, we were interested in further defining the association linking the occurrence of DNA amplification to the emergence of specific breast tumor phenotype. To this aim, we studied by(More)
