Chromatin Dynamics during Lytic Infection with Herpes Simplex Virus 1
Viruses, 2013 Latent HSV-1 genomes are chromatinized with silencing marks. Since 2004, however, there has been an apparent inconsistency in the studies of the chromatinization of the HSV-1 genomes in lytically infected cells.

The Histone Deacetylase SIRT6 Restrains Transcription Elongation via Promoter-Proximal Pausing. [PDF]
, 2019 Transcriptional regulation in eukaryotes occurs at promoter-proximal regions wherein transcriptionally engaged RNA polymerase II (Pol II) pauses before proceeding toward productive elongation.

Inhibition of TGF-β Signaling Promotes Human Pancreatic β-Cell Replication. [PDF]
, 2016 Diabetes is associated with loss of functional pancreatic β-cells, and restoration of β-cells is a major goal for regenerative therapies. Endogenous regeneration of β-cells via β-cell replication has the potential to restore cellular mass; however ...

Advanced Science, EarlyView.ABSTRACT Diabetes mellitus‐induced erectile dysfunction (DMED) is a highly prevalent complication among diabetic patients; however, its underlying pathogenic mechanisms remain incompletely understood. Metabolic disorder is a hallmark of diabetes, yet its precise contribution to DMED progression is not well defined.

DNA-encoded nucleosome occupancy is associated with transcription levels in the human malaria parasite Plasmodium falciparum. [PDF]
, 2014 BackgroundIn eukaryotic organisms, packaging of DNA into nucleosomes controls gene expression by regulating access of the promoter to transcription factors.

Advanced Science, EarlyView.Lung cancer remains the leading cause of cancer‐related death. We investigated the role of the epigenetic regulator DMAP1 in NSCLC and found that its loss induces replication stress and DNA damage. This in turn activates type I IFN signaling via the cGAS–STING pathway and transcriptional ISG de‐repression, enhancing anti‐tumor immune responses ...

Histone Mutants Separate R Loop Formation from Genome Instability Induction [PDF]
, 2017 R loops have positive physiological roles, but they can also be deleterious by causing genome instability, and the mechanisms for this are unknown. Here we identified yeast histone H3 and H4 mutations that facilitate R loops but do not cause instability.

A Functionally Conserved Enhancer is Critical for PGC1A Expression and Thermogenesis in Brown Fat
Advanced Science, EarlyView.An evolutionarily conserved enhancer controls PGC1A expression and thermogenic activation in brown adipose tissue. Integrative multi‐omics analyses identify two BAT‐specific enhancers, with PGC1A‐En1 functioning as the dominant regulatory element that maintains thermogenic capacity across species.

Delivery of Pleckstrin‐Homology Domains Suppresses PI3K/Akt Signaling and Breast Cancer Metastasis
Advanced Science, EarlyView.Current therapies curb tumor growth but not metastasis. Obscurin, a giant metastasis suppressor lost in breast cancer, restrains PI3K/Akt signaling but is impractical to restore. We deploy a mini‐obscurin, comprising the obscurin‐PH‐domain, which sequesters PI3K‐p85, potently suppressing invasion and metastasis.
