Sex-specific regulation of the male-specific lethal-1 dosage compensation gene in Drosophila.
Dosage compensation in Drosophila occurs by a twofold increase in transcription per copy of X-linked genes in males (XY) compared with females (XX). msl-1 is one of four genes that are essential for dosage compensation in males, and MSL-1 protein is associated specifically with the male X chromosome. To explore the basis for the sex specificity of dosage compensation, we examined MSL-1 expressi...
متن کاملConservation of Regional Variation in Sex-Specific Sex Chromosome Regulation.
Regional variation in sex-specific gene regulation has been observed across sex chromosomes in a range of animals and is often a function of sex chromosome age. The avian Z chromosome exhibits substantial regional variation in sex-specific regulation, where older regions show elevated levels of male-biased expression. Distinct sex-specific regulation also has been observed across the male hyper...
متن کاملSex-specific regulation of aging and apoptosis.
Genetic analysis of Drosophila, mice and humans indicates that gene alleles, mutations and transgenes that affect life span tend to do so differently depending on the sex of the organism. The likely reason for this is that the sexes are different genotypes (e.g., X/X vs. X/Y) and face quite different environments: e.g., to reproduce, males have to mate with females while females have to mate wi...
متن کاملUnderstanding Tissue-Specific Gene Regulation.
Although all human tissues carry out common processes, tissues are distinguished by gene expression patterns, implying that distinct regulatory programs control tissue specificity. In this study, we investigate gene expression and regulation across 38 tissues profiled in the Genotype-Tissue Expression project. We find that network edges (transcription factor to target gene connections) have hig...
متن کاملPolyandry and sex-specific gene expression.
Polyandry is widespread in nature, and has important evolutionary consequences for the evolution of sexual dimorphism and sexual conflict. Although many of the phenotypic consequences of polyandry have been elucidated, our understanding of the impacts of polyandry and mating systems on the genome is in its infancy. Polyandry can intensify selection on sexual characters and generate more intense...
