Current concepts on oxidative/carbonyl stress, inflammation and epigenetics in pathogenesis of chronic obstructive pulmonary disease [PDF]

open access: yes, 2011
Chronic obstructive pulmonary disease (COPD) is a global health problem, and current therapy for COPD is poorly effective and the mainstays of pharmacotherapy are bronchodilators.

Identification and Interrogation of Combinatorial Histone Modifications

open access: yesFrontiers in Genetics, 2013
Histone proteins are dynamically modified to mediate a variety of cellular processes including gene transcription, DNA damage repair, and apoptosis. Regulation of these processes occurs through the recruitment of non-histone proteins to chromatin by ...

DNA methylation dynamics in aging: How far are we from understanding the mechanisms? [PDF]

open access: yes, 2018
DNA methylation is currently the most promising molecular marker for monitoring aging and predicting life expectancy. However, the mechanisms underlying age-related DNA methylation changes remain mostly undiscovered.Here we discuss the current knowledge ...

Selective transcriptional regulation by Myc: Experimental design and computational analysis of high-throughput sequencing data

open access: yesData in Brief, 2015
The gene expression programs regulated by the Myc transcription factor were evaluated by integrated genome-wide profiling of Myc binding sites, chromatin marks and RNA expression in several biological models. Our results indicate that Myc directly drives

HIRA defines early replication initiation zones independently of their genome compartment

open access: yesNature Communications
Chromatin states and 3D architecture have been used as proxy to identify replication initiation zones (IZs) in mammalian cells, yet their functional interconnections remain a puzzle.

HDACs and Their Inhibitors on Post-Translational Modifications: The Regulation of Cardiovascular Disease

open access: yesCells
Cardiovascular diseases (CVD), such as myocardial hypertrophy, heart failure, atherosclerosis, and myocardial ischemia/reperfusion (I/R) injury, are among the major threats to human health worldwide. Post-translational modifications alter the function of

Post-translational regulation of proteins in fruit ripening and quality development

open access: yesHorticulture Advances
Fruit ripening and quality formation are complex biological processes governed by multiple layers of regulatory mechanisms, including transcriptional regulation, translational control, and post-translational modifications (PTMs).

The Deletion of the Bre1 Gene in Aspergillus nidulans Impairs Mitotic Growth, Meiosis, and DNA Damage Repair

open access: yes, 2013
Bre1 is a homotetrameric E3 ubiquitin-protein ligase that heterodimerizes with Rad6, an E2 ubiquitin-conjugating enzyme, in order to ubiquitinate lysine 123 in Aspergillus nidulans.

The BAF complex enhances transcription through interaction with H3K56ac in the histone globular domain

open access: yesNature Communications
Histone post-translational modifications play pivotal roles in eukaryotic gene expression. To date, most studies have focused on modifications in unstructured histone N-terminal tail domains and their binding proteins. However, transcriptional regulation
