GenomicsX-chromosome hyperactivation in mammals via nonlinear relationships between chromatin states and transcription
Dosage compensation in mammals occurs at two levels. In addition to balancing X-chromosome dosage between males and females via X-inactivation, mammals also balance dosage of Xs and autosomes. It has been proposed that X-autosome equalization occurs by upregulation of Xa (active X). To investigate t...

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...

TranscriptomicsXist RNA is a potent suppressor of hematologic cancer in mice.
X-chromosome aneuploidies have long been associated with human cancers, but causality has not been established. In mammals, X-chromosome inactivation (XCI) is triggered by Xist RNA to equalize gene expression between the sexes. Here we delete Xist in the blood compartment of mice and demonstrate tha...

TranscriptomicsTestis samples from Alkbh1 wild-type and KO mice
The aim of the study was to elucidate the role of Alkbh1 by targeted deletion in C57/BL6 mice. Alkb deficiency results in sex-ratio distortion of offspring and apoptosis in adult testes, most likely caused by defects in the pachytene stage during spermatogenesis. Due to the pivotal role of Alkbh1 in...

GenomicsDerivation of pre-X inactivation human embryonic stem cells under physiological oxygen concentrations
The presence of two active X chromosomes (XaXa) is a hallmark of the ground state of pluripotency specific to murine embryonic stem cells (ESCs). Human ESCs invariably exhibit signs of X chromosome inactivation (XCI) and are considered developmentally more advanced than their murine counterparts. W...
