The nature and identification of quantitative trait loci: a community's view.
This white paper by eighty members of the Complex Trait Consortium presents a community's view on the approaches and statistical analyses that are needed for the identification of genetic loci that determine quantitative traits. Quantitative trait loci (QTLs) can be identified in several ways, but is there a definitive test of whether a candidate locus… (More)
The Collaborative Cross, a community resource for the genetic analysis of complex traits.
The goal of the Complex Trait Consortium is to promote the development of resources that can be used to understand, treat and ultimately prevent pervasive human diseases. Existing and proposed mouse resources that are optimized to study the actions of isolated genetic loci on a fixed background are less effective for studying intact polygenic networks and… (More)
[Genetic control of the activity of microsomal enzymes of steroidogenesis in Leydig cells of inbred strains of mice].
Four activities of key microsomal steroidogenic enzymes (3 beta-hydroxysteroid dehydrogenase-isomerase, microsomal cytochrome P45017 beta, and 17-ketosteroid reductase) were compared in Leydig cells of six inbred strains of mice: A/He, CBA/Lac, C57BL/6J, DD, YT, and PT. The activities of the enzymes were found to vary considerably from one strain to… (More)
[The role of genotype, social stress, and season of the year in regulation of hormonal function of murine testis in vitro].
Micropopulations consisting of six male mice of different genotypes were studied (each of lines A/He, CBA/Lac, C57BL/6J, DD, YT, and PT was represented by one male). Interlinear differences in the level of social dominance and the effects of genotype, social hierarchy, and season on in vitro testosterone production by testes were examined under different… (More)
[Genetico-neurochemical analysis of the role of brain catecholamines in population hierarchy in male laboratory mice].
Comparative genetic analysis of social dominance in micropopulations of male mice as well as noradrenaline and dopamine levels in brain was carried out. The RT male mice had maximal level of social dominance and the greatest content of brain catecholamines. It is suggested that the capacity for social dominance may depend on the function of the central… (More)
Consensus Sequence of Transcription Factor SF-1 Binding Site and Putative Binding Site in the 5'-Flanking Regions of Genes Encoding Mouse Steroidogenic Enzymes 3βHSDI and Cyp17
Using 42 nucleotide sequences extracted from the Transcription Regulatory Regions Database (TRRD) containing SF-1 transcription factor binding site, we have determined the decanucleotide (GTCAAGGTCA) consensus sequence for SF-1 binding. In the frequency matrix of this sequence nucleotides between the 3rd and the 7th position had the highest frequency and… (More)
Pathways of activation and change of the endocrine function of testes elicited by effect of presence of the female
1. The presence of a receptive female elicits a maximal rise, governed by the synchronous augmentation of its biosynthesis in the male sex gland, in the level of T in the blood plasma and testes in male mice within 20–40 min. Blood T and its production by the testes become normalized by the 80th minute, whereas normalization of its content in the male sex… (More)
