Enzymic Adenosine Diphosphate Ribosylation of Histone and Poly Adenosine Diphosphate Ribose Synthesis in Rat Liver Nuclei

open access: yesJournal of Biological Chemistry, 1968
An enzyme associated with mammalian chromatin catalyzed the transfer of the adenosine diphosphate ribose moiety of nicotinamide adenine dinucleotide to histone with the simultaneous release of nicotinamide. A successive transfer of the ADP-ribose moiety resulted in the formation and elongation of a homopolymer with repeating ADP-ribose units ...

Hepatitis C Virus Nonstructural 5A Protein Inhibits Lipopolysaccharide-Mediated Apoptosis of Hepatocytes by Decreasing Expression of Toll-Like Receptor 4 [PDF]

open access: yes, 2017
Background. Hepatitis C virus (HCV) nonstructural protein 5A (NS5A) has been shown to modulate multiple cellular processes, including apoptosis. The aim of this study was to assess the effects of HCV NS5A on apoptosis induced by Toll-like receptor (TLR ...

Failure to detect "cap" structures in mitochondrial DNA-coded poly(A)-containing RNA from HeLa cells [PDF]

open access: yes, 1978
The structure of the 5'-termini has been investigated in mitochondrial DNA- coded poly(A)-containing RNA from HeLa cells. For this purpose, mitochondrial RNA isolated from cells labeled for 3 hours with [32P]orthophosphate in the presence of 20 µg/ml ...

Effect of 3-aminobenzamide on chromosome damage in human blood lymphocytes adapted to bleomycin [PDF]

open access: yes, 2017
Human blood lymphocytes, pre-treated with very low (adaptation) concentrations of bleomycin for 48 h and then exposed to a high (challenge) dose of the same agent or X-rays, became significantly less sensitive to the induction of chromosome damage than ...

Visualization of poly(ADP-ribose) bound to PARG reveals inherent balance between exo- and endo-glycohydrolase activities [PDF]

open access: yes, 2013
Poly-ADP-ribosylation is a post-translational modification that regulates processes involved in genome stability. Breakdown of the poly(ADP-ribose) (PAR) polymer is catalysed by poly(ADP-ribose) glycohydrolase (PARG), whose endo-glycohydrolase activity ...

Lexicon for Clonal Hematopoiesis in Liquid Biopsy

open access: yesClinical and Translational Science, Volume 19, Issue 1, January 2026.
ABSTRACT Historically, clonal hematopoiesis (CH) has been recognized as a confounder of cell‐free DNA (cfDNA) testing. Recent evidence now demonstrates the role of CH as a risk factor in health, generating distinct sources of cfDNA that can be leveraged for liquid biopsy diagnostics.

Structural characterisation of nucleotide sugar short‐chain dehydrogenases/reductases from the thermophilic pseudomurein‐containing methanogen Methanothermobacter thermautotrophicus ΔH

open access: yesThe FEBS Journal, Volume 293, Issue 2, Page 492-513, January 2026.
Nucleotide sugar short‐chain dehydrogenases/reductases (NS‐SDRs) are involved in pseudomurein and capsular polysaccharide formation in methanogenic Archaea. Methanothermobacter thermautotrophicus possesses several NS‐SDRs labelled Mth375, Mth380, Mth373, Mth631 and Mth1789.
