MetabolomicsX chromosome dosage drives statin-induced dysglycemia and mitochondrial dysfunction

Statin drugs lower blood cholesterol levels for cardiovascular disease prevention. Women are more likely than men to experience adverse statin effects, particularly new-onset diabetes (NOD) and muscle weakness. Here we find that impaired glucose homeostasis and muscle weakness in statin-treated f...

TranscriptomicsEscape from X chromosome inactivation occurs within topologically associated domains
The spatial proximity between regulatory elements and their target genes has a profound affect on gene expression. X Chromosome Inactivation (XCI) is an epigenetic process by which an entire chromosome is rendered, for the most part, transcriptionally silent. A few genes are known to escape XCI and ...

GenomicsSpreading of X-chromosome inactivation via a hierarchy of defined Polycomb stations
Binding of Polycomb repressive complex 2 (PRC2) and chromatin composition of the inactive X (Xi) before, during and after X chromosome inactivation reveal that spreading is driven by a combination of Xi-specific strong and moderate Ezh2 sites. Sequence context of these sites shows a moderate enrichm...

TranscriptomicsX-chromosome inactivation in monkey embryos and pluripotent stem cells
In this study, we explored x-inactivation in monkey embryos (ICM and TE separately) and pluripotent stem cells (IVF derived ES, SCNT-derived ES and monkey iPS) To elucidate x-inactivation in experimentally reprogrammed pluripotent cells, we derived pluripotent stem cells by both SCNT and iPS approac...

GenomicsSmchd1 dependent and independent pathways determine developmental dynamics of CpG island methylation on the inactive X chromosome.
X chromosome inactivation involves multiple levels of chromatin modification, established progressively and in a stepwise manner during early development. The chromosomal protein Smchd1 has recently been shown to play an important role in DNA methylation of CpG islands (CGIs), a late step in the X i...

GenomicsX-chromosome dynamics revealed by the RNA interactome and chromosomal binding of CTCF
CTCF is a master regulator that plays a role in genome architecture and gene expression. A key aspect of CTCF’s mechanism involves bringing together distant genetic elements for intra- and inter-chromosomal interactions. Evidence from epigenetic processes, such as X-chromosome inactivation (XCI), su...

ProteomicsThe role of early chromatin changes in X chromosome inactivation
During development, transcriptional and chromatin modification changes co-occur but the order and causality of events often remain unclear. We explore the interrelationship of these processes using the paradigm of X-chromosome inactivation (XCI). We initiate XCI in female, mouse embryonic stem cells...

TranscriptomicsHigh-resolution chromosomal maps of Xist RNA reveal a two-step spreading mechanism during X-inactivation
The Xist long noncoding RNA (lncRNA) is essential for X-chromosome inactivation (XCI), the process by which mammals compensate for unequal numbers of sex chromosomes. During XCI, Xist coats the future inactive X (Xi) and recruits Polycomb Repressive Complex 2 (PRC2) to the X-inactivation center (Xic...

ProteomicsSegmental X-chromosome monosomies are compensated by transcriptional upregulation.
XX mice undergo both X-chromosome inactivation (XCI) and X-chromosome upregulation (XCU) to balance X-linked gene dosage with autosomes and XY mice. XCU has also been reported in XY cells, as well as cells with a single copy of the X-chromosome (XO). The two dosage compensation processes have been s...

Induced pluripotent stem cells (iPSCs) offer opportunity for insight into the genetic requirements of the X chromosome for somatic and germline development. Turner syndrome is caused by complete or partial loss of the second sex chromosome; while more than 90% of Turner cases result in spontaneous f...
