Advanced Science, EarlyView.This study reveals a copper‐driven mechanism of COPD acute exacerbations mediated by the TNF‐α/ATP7A axis. TNF‐α suppresses the copper transporter ATP7A via competitive NF‐κB/CREB1/CBP signaling, resulting in intracellular copper accumulation, mitochondrial oxidative stress, and epithelial barrier disruption.

Cryo-EM structure of a licensed DNA replication origin
Nature Communications, 2017 Origins of replication are licensed by loading of MCM onto DNA, and origin firing depends on interaction with Cdc45 and GINS to form two CMG holo-helicases. Here, authors determine the cryo-EM structures of DNA-bound MCM and visualise a phospho-dependent

The structural role of histone H2A variants in chromatin function
, 2008 Chromatin is a highly dynamic complex that facilitates the structural transitions required for specific gene expression. An emerging player in the regulation of such chromatin functions are histone H2A variants.

Advanced Science, EarlyView.ABSTRACT The LRRK2 G2019S mutation, a Parkinson's disease–linked variant, has been associated with depression‐like phenotypes, but mechanisms remain unclear. We chart age‐dependent behavioral changes and astrocyte reactivity in G2019S mice and define a pathway connecting LRRK2 to TFEB/GDNF signaling, cellular energetics, and inflammation.

UNCOVERING THE MECHANISM OF CHROMATIN ASSOCIATION OF THE PAF1 TRANSCRIPTION ELONGATION COMPLEX [PDF]
, 2013 Paf1C co-localizes with Pol II and influences gene expression by regulating transcription initiation, elongation and termination. Some crucial functions of Paf1C include promoting co-transcriptional histone modifications and recruiting termination ...

Genome-wide views of chromatin structure
, 2010 Eukaryotic genomes are packaged into a nucleoprotein complex known as chromatin, which affects most processes that occur on DNA. Along with genetic and biochemical studies of resident chromatin proteins and their modifying enzymes, mapping of chromatin ...

Advanced Science, EarlyView.In this study, we unveil a thymus‐brain endocrine axis wherein Tα1 engages HCRTR1 to inhibit RIPK3‐mediated necroptosis. This study nominates the Tal‐HCRTR1‐RIPK3 axis as a potent and clinically translatable therapeutic target for stroke and neurodegeneration.
