GenomicsA system for genome-wide histone variant dynamics in ES cells reveals dynamic MacroH2A2 replacement at promoters
Our system recapitulates expected characteristics of the well characterized H3.3 histone variant, and show that we gain additional information by using a kinetic approach. Additionaly, our results on the less-studied MacroH2A2 variant revealed differential dynamic profiles of this M-bM-^@M-^\repress...

TranscriptomicsMetastable pluripotent states in NOD mouse derived ES cells
Embryonic stem (ES) cells are isolated from the inner cell mass (ICM) of developing blastocysts, whereas epiblast stem cells (EpiSCs) are derived from the post-implantation epiblast and are characterized by a restricted developmental potential. Although certain mouse strains, such as the non-obese d...

TranscriptomicsIntestinal epithelial gene expression - TRE-MSI2
Comparison of gene expression in intestinal epithelial cells in the presence or absence of ectopic induction of MSI2 in vivo Total RNA was isolated from preparations of total intestinal epithelial cells taken from the jejunum from 3 control (R26-M2rtTA +doxycycline for 24 hrs) and 3 experimental (TR...

TranscriptomicsTransformation of the intestinal epithelium by the MSI2 RNA binding protein
The MSI2 RNA binding protein has recently emerged as a potent oncogene playing key roles in hematopoietic stem cell homeostasis and malignant hematopoiesis. Here we demonstrate that MSI2 is expressed in the intestinal stem cell compartment, that its expression is elevated in colorectal adenocarcinom...

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...

TranscriptomicsMsi1 integrates APC loss and mTORC1 activation to promote intestinal stem cell transformation
Loss of the APC tumor suppressor in the intestinal epithelium initiates the majority of human colorectal adenocarcinomas. Constitutive β-catenin activation is thought to underlie tumorigenesis induced by loss of APC, however β-catenin activation alone does not recapitulate all APC-loss phenotypes,...

TranscriptomicsMusashi 2 regulates normal hematopoiesis and accelerates leukemogenesis (LSK and LK)
We demonstrate that Msi2 is the predominant form expressed in hematopoietic stem cells (HSC), and its knockdown leads to reduced engraftment and depletion of HSCs in vivo. Overexpression of Msi2 in a mouse model increases HSC cell cycle progression and cooperates with BCR-ABL1 to induce an aggressiv...
