1. Chromosome-wide gene regulatory mechanisms in Drosophila melanogaster
Abstract : In Drosophila there are two different chromosome-wide targeting systems, the dosage compensation system that equalizes the transcriptional output from X-linked genes between males and females, and the regulation of the 4th chromosome mediated by the POF protein. The best studied of these two mechanisms is the dosage compensation system. READ MORE

2. Mining DNA elements involved in targeting of chromatin modifiers
Abstract : Background: In all higher organisms, the nuclear DNA is condensed into nucleosomes that consist of DNA wrapped around a core of highly conserved histone proteins. DNA bound to histones and other structural proteins form the chromatin. READ MORE

3. Chromosome-specific adaptations of RNA stability and the roles of the roX RNAs in dosage compensation
Abstract : Sex chromosomes evolved from an ancient pair of autosomes and the Y chromosome lost most of its genetic information in the process. This created two kinds of genomic imbalances: the first one between males (XY) and females (XX) and the second one between the sex chromosomes and the autosomes (X:AA). READ MORE

4. Aneuploidy compensatory mechanisms and genome-wide regulation of gene expression in Drosophila melanogaster
Abstract : Stimulation or repression of gene expression by genome-wide regulatory mechanisms is an important epigenetic regulatory function which can act to efficiently regulate larger regions or specific groups of genes, for example by compensating for loss or gain of chromosome copy numbers. In Drosophila melanogaster there are two known chromosome-wide regulatory systems; the MSL complex, which mediates dosage compensation of the single male X-chromosome and POF, which stimulates expression from the heterochromatic 4th chromosome.
