1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

In spermiogenesis, spermatid differentiation is marked by dramatic changes in chromatin density and composition. The extreme condensation of the spermatid nucleus is characterized by an exchange of histones to transition proteins and then to protamines as the major nuclear proteins. Alterations in DNA topology that occur in this process have been shown to require the controlled formation of DNA strand breaks. Poly(ADP-ribosyl)ation is a posttranslational modification of proteins mediated by a family of poly(ADP-ribose) polymerase (PARP) proteins, and two family members, PARP-1 and PARP-2, are activated by DNA strand breaks that are directly detected by the DNA-binding domains of these enzymes. Here, we show for the first time that poly(ADP-ribose) formation, mediated by poly(ADP-ribose) polymerases (PARP-1 and presumably PARP-2), occurs in spermatids of steps 11-14, steps that immediately precede the most pronounced phase of chromatin condensation in spermiogenesis. High levels of ADP-ribose polymer were observed in spermatid steps 12-13 in which the highest rates of chromatin nucleoprotein exchanges take place. We also detected gamma-H2AX, indicating the presence of DNA double-strand breaks during the same steps. Thus, we hypothesize that transient ADP-ribose polymer formation may facilitate DNA strand break management during the chromatin remodeling steps of sperm cell maturation.
