Enzyme characteristics of recombinant poly(ADP-ribose) polymerases-1 of rat and human origin mirror the correlation between cellular poly(ADP-ribosyl)ation capacity and species-specific life span

Abstract

Poly(ADP-ribosyl)ation is a posttranslational modification, which is involved in many cellular functions, including DNA repair and maintenance of genomic stability, and has also been implicated in cellular and organismal ageing. We have previously reported that maximum poly(ADP-ribosyl)ation capacity in mononuclear blood cells is correlated with mammalian life span. Here we show that the difference between a long-lived and a short-lived species tested (i.e. man and rat) is directly mirrored by the enzymatic parameters of recombinant poly(ADP-ribose) polymerase-1 (PARP-1), i.e. substrate affinity and reaction velocity. In addition, we have characterized two human PARP-1 alleles and assign their activity difference to their respective initial velocity and not substrate affinity.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
