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

Destabilized mutant p53s coaggregate with WT p53, p63, and p73 in cancer cell lines. We found that stoichiometric amounts of aggregation-prone mutants induced only small amounts of WT p53 to coaggregate, and preformed aggregates did not significantly seed the aggregation of bulk protein. Similarly, p53 mutants trapped only small amounts of p63 and p73 into their p53 aggregates. Tetrameric full-length protein aggregated at similar rates and kinetics to isolated core domains, but there was some induced aggregation of WT by mutants in hetero-tetramers. p53 aggregation thus differs from the usual formation of amyloid fibril or prion aggregates where tiny amounts of preformed aggregate rapidly seed further aggregation. The proposed aggregation mechanism of p53 of rate-determining sequential unfolding and combination of two molecules accounts for the difference. A molecule of fast-unfolding mutant preferentially reacts with another molecule of mutant and only occasionally traps a slower unfolding WT molecule. The mutant population rapidly self-aggregates before much WT protein is depleted. Subsequently, WT protein self-aggregates at its normal rate. However, the continual production of mutant p53 in a cancer cell would gradually trap more and more WT and other proteins, accounting for the observations of coaggregates in vivo. The mechanism corresponds more to trapping by cross-reaction and coaggregation rather than classical seeding and growth.
