TranscriptomicsTranscription profiling of Drosophila male third instar larva y+ w roX1- roX2-/y vs y+ w roX1+ roX2-/y reveals roX RNAs are required for increased expression of X-linked genes in Drosophila melanogaster males
Drosophila males double transcription of their single X chromosome to equalize X-linked gene expression with females, which carry two X chromosomes. Increased transcription requires the Male-Specific Lethal (MSL) complex. One of the primary functions of the MSL complex is thought to be enrichment ...

TranscriptomicsExpression data from human triploid and diploid fibroblast cell cultures
Dosage compensation restores a balanced network of gene expression between autosomes and sex chromosomes in males (XY) and females (XX). In mammals, this is achieved by doubling the expression of X-linked genes in both sexes, together with X inactivation in females. X up-regulation may be controlled...

TranscriptomicsExpression analysis in mouse female PGK12.1 ES cells by RNA-seq
Many animal species employ a chromosome-based mechanism of sex determination, which has led to coordinate evolution of dosage compensation systems. Dosage compensation not only corrects the imbalance in the number of X-chromosomes between the sexes, but is also hypothesized to correct dosage imbalan...

TranscriptomicsTranscription profiling of Drosophila msl21 male larvae reveals MSL2 is required for upregulation of male X chromosome but not for expression of autosomal genes
Drosophila males double transcription of their single X chromosome to equalize X-linked gene expression with females, which carry two X chromosomes. Increased transcription requires the Male-Specific Lethal (MSL) complex. The MSL2 protein is essential component of the MSL complex. MSL2 is the only p...

TranscriptomicsFemale-specific CTCF binding on the inactive X chromosome in mouse
In mammals, genes located on the X chromosome are present in one copy in XY males and two in XX females. To balance the dosage of X-linked gene expression between the sexes one of the two X chromosomes in females is silenced by X inactivation initiated by up-regulation of the lncRNA (long non-coding...

TranscriptomicsNucleophosmin binding on the mouse X chromosomes
In mammals, one of the female X chromosomes and all imprinted genes are expressed exclusively from a single allele in somatic cells. To evaluate structural changes associated with allelic silencing, we have applied a recently developed Hi-C assay that uses DNase I for chromatin fragmentation to mous...

TranscriptomicsUpregulation of the mammalian X chromosome is associated with enhanced transcription initiation, MOF-mediated H4K16 acetylation, and longer RNA half-life
Many animal species employ a chromosome-based mechanism of sex determination, which has led to coordinate evolution of dosage compensation systems. Dosage compensation not only corrects the imbalance in the number of X-chromosomes between the sexes, but is also hypothesized to correct dosage imbalan...

TranscriptomicsEscape from X inactivation in mouse tissues (RNA-Seq)
X chromosome inactivation (XCI) silences most genes on one X chromosome in female mammals, but some genes escape XCI. To identify escape gene in vivo and to explore molecular mechanisms that regulate this process we analyzed the allele-specific expression and chromatin structure of X-linked genes in...
