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

REV1, a Y family DNA polymerase (pol), is involved in replicative bypass past DNA lesions, so-called translesion DNA synthesis. In addition to a structural role as a scaffold protein, REV1 has been proposed to play a catalytic role as a dCTP transferase in translesion DNA synthesis past abasic and guanine lesions in eukaryotes. To better understand the catalytic function of REV1 in guanine lesion bypass, purified recombinant human REV1 was studied with two series of guanine lesions, N(2)-alkylG adducts (in oligonucleotides) ranging in size from methyl (Me) to CH(2)(6-benzo[a]pyrenyl) (BP) and O(6)-alkylG adducts ranging from Me to 4-oxo-4-(3-pyridyl)butyl (Pob). REV1 readily produced 1-base incorporation opposite G and all G adducts except for O(6)-PobG, which caused almost complete blockage. Steady-state kinetic parameters (k(cat)/K(m)) were similar for insertion of dCTP opposite G and N(2)-G adducts but were severely reduced opposite the O(6)-G adducts. REV1 showed apparent pre-steady-state burst kinetics for dCTP incorporation only opposite N(2)-BPG and little, if any, opposite G, N(2)-benzyl (Bz)G, or O(6)-BzG. The maximal polymerization rate (k(pol) 0.9 s(-1)) opposite N(2)-BPG was almost the same as opposite G, with only slightly decreased binding affinity to dCTP (2.5-fold). REV1 bound N(2)-BPG-adducted DNA 3-fold more tightly than unmodified G-containing DNA. These results and the lack of an elemental effect ((S(p))-2'-deoxycytidine 5'-O-(1-thiotriphosphate)) suggest that the late steps after product formation (possibly product release) become rate-limiting in catalysis opposite N(2)-BPG. We conclude that human REV1, apparently the slowest Y family polymerase, is kinetically highly tolerant to N(2)-adduct at G but not to O(6)-adducts.
