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

Environmental polycyclic aromatic hydrocarbons (PAHs) are metabolically activated to diol epoxides that can react with DNA, resulting in covalent modifications to the bases. The (+)- and (-)-3,4-dihydroxy-1,2-epoxy-1,2,3,4-tetrahydro-benzo[c]phenanthrene (anti-BPhDE) isomers are diol epoxide metabolites of the PAH benzo[c]phenanthrene (BPh). These enantiomers readily react with DNA at the N6 position of adenine, forming bulky (+)-1R- or (-)-1S-trans-anti-[BPh]-N6-dA adducts. Transcription-coupled nucleotide excision repair clears such bulky adducts from cellular DNA, presumably in response to RNA polymerase transcription complexes that stall at the bulky lesions. Little is known about the effects of [BPh]-N6-dA lesions on RNA polymerase II, hence, the behavior of human RNA polymerase II was examined at these adducts. A site-specific, stereochemically pure [BPh]-N6-dA adduct was positioned on the transcribed or non-transcribed strand of a DNA template with a suitable promoter for RNA polymerase II located upstream from the lesion. Transcription reactions were then carried out with HeLa nuclear extract. Each [BPh]-dA isomer strongly impeded human RNA polymerase II progression when it was located on the transcribed strand; however, a small but significant degree of lesion bypass occurred, and the extent of polymerase blockage and bypass was dependent on the stereochemistry of the adduct. Molecular modeling of the lesions supports the idea that each adduct can exist in two orientations within the polymerase active site, one that permits nucleotide incorporation and another that blocks the RNA polymerase nucleotide entry channel, thus preventing base incorporation and causing the polymerase to stall or arrest.
