A multi-omics integrative analysis based on CRISPR screens re-defines the pluripotency regulatory network in ESCs

Genome-scale CRISPR screen to identify regulators that maintain mESC pluripotency To establish a function-based PGRN, we first performed a CRISPR-Cas9 mediated genome-wide screen to detect genes essential for self-renewal. mESCs were cultured under Leukaemia inhibitory factors (LIF)/serum condition (L/S), which was commonly used in similar tasks and confer a naïve…

Acetylation of histone H2B marks active enhancers and predicts CBP/p300 target genes

Multiple H2BNTac sites occupy the same genomic regions H2BNTac sites are similarly regulated by CBP/p30018 (Supplementary Fig. 1a), yet the reported genome occupancy patterns of H2BNTac sites are dissimilar from each other22,23 (Supplementary Note 1). To resolve this conundrum, we systematically compared H3K27ac and H2BNTac genomic occupancy and regulation by…

Genome-wide 5-hydroxymethylcytosine (5hmC) reassigned in Pten-depleted mESCs along neural differentiation

DNA methylation and hydroxymethylation have been implicated in the regulatory dynamics of gene expression in normal development and differentiation. 5-Hydroxymethylcytosine (5hmC), created by the ten-eleven translocation (TET) protein-catalyzed oxidation of 5-methylcytosine (5mC), is abundant in the brain, but the genome-wide distribution and impact of 5hmC during diverse neuronal differentiation remain…

Report Exposes Rot In Middle East Studies Centers, Connection to CRT

Neetu Arnold, Senior Research Associate of the National Association of Scholars (NAS) has done what amounts to an expose of the politicization of campus Middle East studies centers. What began as – let’s say, a coincidence of timing between generous Arab donations to university study centers offering a pro-Arab, anti-Israel…

Absolute Scaling of Single-Cell Transcriptomes Reveals Pervasive Hypertranscription in Adult Stem and Progenitor Cells

Introduction Single cell RNA-seq (scRNA-seq) is a powerful tool to measure gene expression in individual cells. While relative gene expression differences are currently analyzed with great interest in single cell data, differences in total transcript levels were mainly considered technical artefacts and removed during normalization, assuming that single cells contain…

Frontiers | Hair Graying Regulators Beyond Hair Follicle

Introduction Hair graying is one of the representative signs of aging. It has been considered to be triggered by a decreased number of follicular melanocyte stem cells (MeSCs; Nishimura et al., 2005; Iida et al., 2020) or dysfunction of MeSCs such as decreased oxidation resistance capacity with aging (Shi et…

From mESCs to mEPSCs: A proteomics-based study

Out laboratory has derived mEPSCs from mESCs, which represents a breakthrough in stem cell research. Unlike the standard pluripotent stem cells, mEPSCs can contribute to both embryonic and extra-embryonic lineages in the chimera assay (Yang et al., 2017a). In the development of EPSC culture conditions, many small molecules are tested…

p57 Suppresses the Pluripotency and Proliferation of Mouse Embryonic Stem Cells by Positively Regulating p53 Activation

Embryonic stem cells (ESCs) are pluripotent stem cells that have indefinite self-renewal capacities under appropriate culture conditions in vitro. The pluripotency maintenance and proliferation of these cells are delicately governed by the concert effect of a complex transcriptional regulatory network. Herein, we discovered that p57Kip2 (p57), a cyclin-dependent kinase inhibitor…
