EGR Proteins Mediate Interferon‐Independent Anti‐HSV‐1 Responses Through Viral and Host Targets

Advanced Science, EarlyView.
Early antiviral responses are typically mediated by interferons. However, during HSV‐1 infection, host early growth response (Egr) genes, which are not interferon‐stimulated genes, are quickly induced by viral protein ICP0. EGR proteins, in turn, suppress viral lytic infection by activating viral latency‐associated (LAT) and host immune regulatory ...

HP1a-mediated heterochromatin formation inhibits high dietary sugar-induced tumor progression

Cell Death and Disease, 2021
High dietary sugar (HDS) is a modern dietary concern that involves excessive consumption of carbohydrates and added sugars, and increases the risk of metabolic disorders and associated cancers.

Epigenetic Chromatin Silencing: Bistability and Front Propagation

, 2007
The role of post-translational modification of histones in eukaryotic gene regulation is well recognized. Epigenetic silencing of genes via heritable chromatin modifications plays a major role in cell fate specification in higher organisms.

The architecture of chicken chromosome territories changes during differentiation [PDF]

, 2004
BACKGROUND: Between cell divisions the chromatin fiber of each chromosome is restricted to a subvolume of the interphase cell nucleus called chromosome territory.

SETDB2 Mitigates Podocyte Dysfunction in Diabetic Kidney Disease Through Epigenetic Silencing of SMAD3

Advanced Science, EarlyView.
SETDB2 epigenetically represses Smad3 transcription by increasing H3K9me3 enrichment at its promoter, thereby mitigating podocyte dysfunction in DKD. The transcription factor TCF21 binds directly to the Setdb2 promoter and enhances its expression in podocytes. Abstract Podocyte dysfunction represents both an early pathological hallmark and a key driver

The Drosophila histone variant H2A.V works in concert with HP1 to promote kinetochore-driven microtubule formation [PDF]

, 2015
Unlike other organisms that have evolved distinct H2A variants for different functions, Drosophila melanogaster has just one variant which is capable of filling many roles.

EIF5A Couples Translational Control With Transcriptional Reprogramming Through Chromocenter Reorganization During Spermiogenesis

Advanced Science, EarlyView.
The translation factor Eukaryotic translation initiation factor 5A (eIF5A) is essential for male fertility in mice. It supports the translation of proteins crucial for heterochromatin organization and acrosome formation. eIF5A deficiency disrupts chromocenter integrity, increases chromatin accessibility, and causes transcriptional dysregulation ...
