Pyrazole‐Derived Antibacterial Compounds Effectively Treat Methicillin‐Resistant Staphylococcus Aureus Infections by Inhibiting Aspartate Transcarbamoylase

Advanced Science, EarlyView.
This study unveils a novel antibacterial mechanism against MRSA, in which the compound Py‐27 selectively targets and inhibits aspartate transcarbamoylase (ATCase), a key enzyme in pyrimidine synthesis. This inhibition disrupts DNA replication, induces oxidative damage, leading to potent bactericidal activity.

X-CHROMOSOME INACTIVATION IN MAMMALS

, 1997
▪ Abstract  The inactive X chromosome differs from the active X in a number of ways; some of these, such as allocyclic replication and altered histone acetylation, are associated with all types of epigenetic silencing, whereas others, such as DNA ...

Genetic Ablation and Multi‐Omics Profiling Reveal CEP55 as a Key Driver of Tumorigenesis in Diverse Cancer Models

Advanced Science, EarlyView.
Genetic ablation of Cep55 in Pten‐deficient mouse models delays tumorigenesis. Integrated multi‐omics analyses (proteomics, phosphoproteomics, and spatial transcriptomics) reveal that CEP55 regulates oncogenic signaling (RAS/ERK, PI3K/AKT), integrin/FAK‐mediated adhesion, extracellular matrix (ECM) remodeling, and endocytosis.

Recent advances in X-chromosome inactivation [PDF]

, 2011
X-chromosome inactivation is a paradigmatic epigenetic phenomenon that results in the mitotically heritable transcriptional inactivation of one X-chromosome in female mammals, thereby equalizing X-linked gene dosage between the sexes.

Novel Cell Intrinsic and Extrinsic Mechanisms of X-chromosome Inactivation

, 2022
X-chromosome inactivation equalizes X-linked gene expression between XX female and XY male therian mammals by silencing gene transcription from one X chromosome in early female embryos.

The history of X-chromosome inactivation and relation of recent findings to understanding of human X-linked conditions

The Turkish Journal of Pediatrics, 1995
This paper represents the text of two lectures given on the occasion of a Workshop on the X-Chromosome held at Hacettepe University, Ankara, in September 1994.

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.

Deltacoronavirus Modulates circRNA cGLIS3 Metabolism to Evade Host Antiviral Response

Advanced Science, EarlyView.
This study reveals that both deltacoronavirus nucleocapsid protein and host RNA binding protein IGF2BP2 promote circular RNA GLIS3 (cGLIS3) biogenesis by binding to GLIS3 pre‐mRNA. The m6A modification‐mediated cGLIS3‐IGF2BP2 interaction weakens RNase L‐mediated degradation of cGLIS3 while facilitates a ubiquitin‐dependent degradation of IGF2BP2, thus ...

Identification of skewed X chromosome inactivation using exome and transcriptome sequencing in patients with suspected rare genetic disease

BMC Genomics
Background X-chromosome inactivation (XCI) is an epigenetic process that occurs during early development in mammalian females by randomly silencing one of two copies of the X chromosome in each cell.

Dosage compensation in the process of inactivation/reactivation during both germ cell development and early embryogenesis in mouse

Scientific Reports, 2017
Ohno proposed that dosage compensation in mammals evolved as a two-step mechanism involving X-inactivation and X-upregulation. While X-inactivation is well characterized, it remains to further analysis whether upregulation of the single activated X ...
