Reduced resistance to oxidative stress during reproduction as a cost of early-life stress

, 2015
This study was funded by a BBSRC David Phillips Research Fellowship to K.A. Spencer.Stress exposure during early-life development can have long-term consequences for a variety of biological functions including oxidative stress.

Pneumococcal Gene Complex Involved in Resistance to Extracellular Oxidative Stress [PDF]

, 2012
Streptococcus pneumoniae is a Gram-positive bacterium which is a member of the normal human nasopharyngeal flora but can also cause serious disease such as pneumonia, bacteremia, and meningitis. Throughout its life cycle, S.

Oxidative stress: oxidants and antioxidants [PDF]

Experimental Physiology, 1997
An imbalance between oxidants and antioxidants in favour of the oxidants, potentially leading to damage, is termed ‘oxidative stress’. Oxidants are formed as a normal product of aerobic metabolism but can be produced at elevated rates under pathophysiological conditions. Antioxidant defense involves several strategies, both enzymatic and non‐enzymatic.

Distinct roles of histone H2B ubiquitination at promoters and coding regions of Pol II-transcribed stress genes

Genome Biology
Background The histone code, comprised of diverse histone post-translational modifications, intricately regulates nucleosome organization and gene expression. Histone marks also serve as binding sites for a diverse array of protein complexes and enzymes,

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Oxidative Shielding or Oxidative Stress? [PDF]

The Journal of Pharmacology and Experimental Therapeutics, 2012
In this review I report evidence that the mainstream field of oxidative damage biology has been running fast in the wrong direction for more than 50 years. Reactive oxygen species (ROS) and chronic oxidative changes in membrane lipids and proteins found in many chronic diseases are not the result of accidental damage.

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

FEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

FEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Effects of an Exercise Test on Inflammation and Oxidative Stress Biomarkers in Patients with Metabolic Syndrome

Proceedings, 2019
Metabolic syndrome is characterized by an increase in oxidative stress and chroniclow-grade inflammation. The effects of an exercise test at 60–70% of the maximum capacity wasevaluated on inflammatory and antioxidant response in elderly people ...
