HLA-G1 increases the radiosensitivity of human tumoral cells.

Different molecules regulate the response of tumoral tissues to ionizing radiation. The objective of this work was to determine if HLA-G1 expression modulates the radiosensitivity of human tumoral cell lines. To this end, human melanoma M8 and human erythroleukemia K562 cell lines, with their correspondent HLA-G1 negative and positive variants, were gamma irradiated and the survival frequency was determined by clonogenic assay.

Whole-genome analysis of a daptomycin-susceptible enterococcus faecium strain and its daptomycin-resistant variant arising during therapy.

Development of daptomycin (DAP) resistance in Enterococcus faecalis has recently been associated with mutations in genes encoding proteins with two main functions: (i) control of the cell envelope stress response to antibiotics and antimicrobial peptides (LiaFSR system) and (ii) cell membrane phospholipid metabolism (glycerophosphoryl diester phosphodiesterase and cardiolipin synthase [cls]). However, the genetic bases for DAP resistance in Enterococcus faecium are unclear. We performed whole-genome comparative analysis of a clinical strain pair, DAP-susceptible E.

Genetic basis for in vivo daptomycin resistance in enterococci.

Background: Daptomycin is a lipopeptide with bactericidal activity that acts on the cell membrane of enterococci and is often used off-label to treat patients infected with vancomycin-resistant enterococci. However, the emergence of resistance to daptomycin during therapy threatens its usefulness.

Methods: We performed whole-genome sequencing and characterization of the cell envelope of a clinical pair of vancomycin-resistant Enterococcus faecalis isolates from the blood of a patient with fatal bacteremia; one isolate (S613) was from blood drawn before treatment and the other isolate (R712) was from blood drawn after treatment with daptomycin.

ADH1B*3 and response to alcohol in African-Americans.

Background: Variations in the alleles for the alcohol-metabolizing enzymes have been shown to influence risk for alcohol dependence. One variant, ADH1B*3, is observed almost exclusively in populations of African ancestry and has been shown to be associated with reduced rates of alcohol dependence. We conducted an alcohol challenge study to test whether ADH1B*3 is associated with differences in subjective and physiological response to alcohol.

Addictions biology: haplotype-based analysis for 130 candidate genes on a single array.

Aims: To develop a panel of markers able to extract full haplotype information for candidate genes in alcoholism, other addictions and disorders of mood and anxiety.

Methods: A total of 130 genes were haplotype tagged and genotyped in 7 case/control populations and 51 reference populations using Illumina GoldenGate SNP genotyping technology, determining haplotype coverage. We also constructed and determined the efficacy of a panel of 186 ancestry informative markers.

Association of dopamine, serotonin, and nicotinic gene polymorphisms with methylphenidate response in ADHD.

Gene polymorphisms of the 3' untranslated region (3'-UTR) of the dopamine transporter (DAT1), Dopamine receptor exon 3 D4 variable number tandem repeat (DRD4VNTR), nicotinic acetylcholine receptor alpha 4 subunit (CHRNA4) and serotonin transporter promoter (SLC6A4-5HTTLPR) are under consideration as potential risk factors for attention-deficit/hyperactivity disorder (ADHD). A post-hoc attempt was made to investigate the association between the allelic variations of these candidate genes and retrospective parental report of response to methylphenidate in an ADHD-enriched, population-based twin sample. Subjects (N = 243) were selected from the twin sample based on parent report that the child had been treated with methylphenidate for ADHD symptoms.

Relationship of 5-HTTLPR genotypes and depression risk in the presence of trauma in a female twin sample.

Several studies have implicated an insertion/deletion polymorphism in the promoter region of the serotonin transporter gene (SLC6A4; 5-HTT) in the development of mood disorders. In the present study of a sample of 247 young adult female twins from Missouri, we examine whether this polymorphism interacts with the effect of adverse life events to increase risk for developing depression. We found a significant interaction between the number of high-activity L(A) alleles and exposure to trauma (OR = 1.

Prenatal smoking exposure and dopaminergic genotypes interact to cause a severe ADHD subtype.

Background: In utero exposure to smoking and alcohol are common risk factors that have been associated with attention-deficit/hyperactivity disorder (ADHD) in human beings and animal models. Furthermore, molecular studies have focused on the association between ADHD and DNA polymorphisms in dopamine pathway-related genes. We examined the joint effects of genetic and prenatal substance exposures on DSM-IV and population-defined subtypes of ADHD.

Mutation screening of the dopamine D2 receptor gene in attention-deficit hyperactivity disorder subtypes: preliminary report of a research strategy.

Attention-deficit hyperactivity disorder (ADHD) is a highly heritable syndrome with onset in childhood that is associated with clinical response to drugs, which increase the release of monoamines, especially dopamine. A variety of studies have reported on genetic associations of ADHD with polymorphisms for various component genes of the dopamine pathway. The promise of preliminary associations found with several genes is mitigated by the significant controversy that exists over what are the appropriate clinical characteristics of ADHD associated with its familial transmission.
