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

The p53 tumor suppressor protein inhibits tumor formation, in part by inducing apoptosis, which is inhibited by anti-apoptotic Bcl-2 family members Bcl-2 and adenovirus E1B 19K. We have identified p53-apoptotic signaling events which are targeted for inhibition by E1B 19K. Apoptotic signaling by p53 induced a Bid-independent conformational change in Bax, a Bax-Bak interaction, release of cytochrome c and Smac/DIABLO from mitochondria, caspase-9 and -3 activation, cleavage of known caspase substrates, and apoptosis. When p53-dependent apoptosis was blocked by E1B 19K expression, E1B 19K bound Bak, and the Bax-Bak interaction was inhibited. Cytochrome c and Smac/DIABLO release from mitochondria was also inhibited in E1B 19K expressing cells and cells remained viable. After a prolonged p53 death stimulus, the inhibition of the mitochondrial death checkpoint by E1B 19K failed, and cytochrome c and Smac/DIABLO were released from mitochondria, and became degraded. Despite this eventual failure to inhibit the mitochondrial checkpoint, caspase-9 and -3 were not activated, and cells remained viable even upon treatment with an exogenous death stimulus. Thus, p53 induces apoptosis in part through Bax and Bak, and even an incomplete inhibition of this mitochondrial checkpoint may be sufficient to confer resistance to cell death.
