Global Characterization of X Chromosome Inactivation in Human Pluripotent Stem Cells

Cell Reports, 2019
Summary: Dosage compensation of sex-chromosome gene expression between male and female mammals is achieved via X chromosome inactivation (XCI) by employing epigenetic modifications to randomly silence one X chromosome during early embryogenesis.

Chromatin Topology Reconfiguration Orchestrates Thermotolerant Male Fertility via GhAL5 in Cotton

Advanced Science, EarlyView.
This study investigates cotton’s high‐temperature (HT) response using multi‑omics. Dynamic 3D genome changes drive expression bias affecting male fertility. The tolerant line shows controlled chromatin dynamics, while the sensitive line exhibits overactivation.

Age-Dependent DNA Methylation Variability on the X-Chromosome in Male and Female Twins

Epigenomes
We aimed to explore the age-dependent epigenetic variability on the X-chromosome with consideration of X-chromosome inactivation by applying a sex-stratified regression analysis to DNA methylation array data on X-linked CpGs in aging identical twins.

Perturbed maintenance of transcriptional repression on the inactive X-chromosome in the mouse brain after Xist deletion

Epigenetics & Chromatin, 2018
Background The long noncoding RNA Xist is critical for initiation and establishment of X-chromosome inactivation during embryogenesis in mammals, but it is unclear whether its continued expression is required for maintaining X-inactivation in vivo ...

Ribosome Homeostasis Regulated by SETD2 Preserves Intestinal Epithelial Barrier

Advanced Science, EarlyView.
SETD2 ablation causes dysregulation and recruitment defects of ribosome biogenesis factors, resulting in translational disorders of barrier maintenance genes, thereby compromising the intestinal barrier. These findings unveil a previously unappreciated role of ribosome biogenesis and translational regulation in preserving the intestinal epithelial ...

Depletion of Sorcs3 Activates Totipotency in Mouse Embryonic Stem Cells by Modulating Key Signaling Pathways

Advanced Science, EarlyView.
In this article, Shuai and colleagues found that depletion of Sorcs3 could activate totipotency in mESCs, promising bidirectional differentiation potential to embryonic and extraembryonic lineages. The underlying mechanism might be activation of Tfap2c and repression of TGF‐β, PI3K‐AKT, and lysosome pathways.

X-autosome and X-Y translocations in female carriers: X-chromosome inactivation easily detectable by 5-ethynyl-2-deoxyuridine (EdU)

Balkan Journal of Medical Genetics, 2017
Here we report one new case each of an X-autosome translocation (maternally derived), and an X-Y-chromosome translocation. Besides characterizing the involved breakpoints and/or imbalances in detail by molecular cyto-genetics, also skewed X-chromosome ...

Landscape of DNA methylation on the X chromosome reflects CpG density, functional chromatin state and X-chromosome inactivation

Human Molecular Genetics, 2014
X-chromosome inactivation (XCI) achieves dosage compensation between males and females through the silencing of the majority of genes on one of the female X chromosomes. Thus, the female X chromosomes provide a unique opportunity to study euchromatin and

Allelic Variation in Maize Malate Dehydrogenase 7 Shapes Promoter Methylation and Banded Leaf and Sheath Blight Resistance

Advanced Science, EarlyView.
In this study maize chloroplastic malate dehydrogenase7 (ZmMDH7), is identified as a Rhizoctonia solani resistance gene in maize. ZmMDH7 is regulated by transcription factor ZmWRKY44 via pathogens challenge to elevate mitochondrial ROS and SA signaling pathway.
