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 ...

DNA damage-induced YTHDC1 O-GlcNAcylation promotes homologous recombination by enhancing m6A binding
Fundamental ResearchN6-methyladenosine (m6A) is the most prevalent internal RNA modification, and its regulators include writers, readers and erasers. m6A is under stringent control and takes part in many biological events, but it is not known whether there is an interplay ...

PARPs and the DNA damage response [PDF]
Carcinogenesis, 2012 Adenosine diphosphate (ADP)-ribosylation is an important posttranslational modification catalyzed by a variety of enzymes, including poly (ADP ribose) polymerases (PARPs), which use nicotinamide adenine dinucleotide (NAD(+)) as a substrate to synthesize and transfer ADP-ribose units to acceptor proteins.

The Adaptive Significance of Natural Genetic Variation in the DNA Damage Response of Drosophila melanogaster. [PDF]
, 2016 Despite decades of work, our understanding of the distribution of fitness effects of segregating genetic variants in natural populations remains largely incomplete. One form of selection that can maintain genetic variation is spatially varying selection,

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

ATM Activation and DNA Damage Response [PDF]
Cell Cycle, 2007 Well before the gene (ATM) mutated in the human genetic disorder ataxia-telangiectasia (A-T) was described it was evident from the clinical, molecular and cellular phenotype of A-T that this gene would play a central role in the DNA damage response. Mutation of ATM causes defective cell cycle checkpoint activation,a reduced capacity for repair of DNA ...

DNA Damage and Its Links to Neurodegeneration [PDF]
, 2017 The integrity of our genetic material is under constant attack from numerous endogenous and exogenous agents. The consequences of a defective DNA damage response are well studied in proliferating cells, especially with regards to the development of ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

O‐glycosylation in viruses: A sweet tango
mLifeO‐glycosylation is an ancient yet underappreciated protein posttranslational modification, on which many bacteria and viruses heavily rely to perform critical biological functions involved in numerous infectious diseases or even cancer.

Induction of Stress Granule Assembly is Essential for the Orchestration of DNA Damage Response [PDF]
, 2008 DNA damage provokes several responses including DNA repair, cell cycle regulation and apoptosis that collectively represent the DNA damage response (DDR).
