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

Many tumors overexpress mutant forms of p53. A growing number of studies suggest that the nature of a p53 mutation in a cell can impact upon cellular properties, clinical responses to therapy and prognosis of a tumor. To explore the cellular basis of these observations, experiments were designed to compare the properties of cells with and without p53 mutations within the same cell population. To that end, various tumor-derived human p53 mutants were introduced into p53-null H1299 lung adenocarcinoma cells. Clonogenic survival assays revealed that cells overexpressing the p53His175 mutant, but not the p53His273 mutant, recover preferentially from etoposide treatment. Moreover, p53His175 as well as p53His179 reduced substantially the rate of etoposide-induced apoptosis, whereas p53His273 and p53Trp248 had a much milder protective effect. In contrast, p53His175 and p53His273 exerted very similar effects on the cellular response to cisplatin; both conferred increased resistance to low concentrations of the drug (2.5 microg/ml), but did not protect at all against high concentrations (10 microg/ml). Hence particular p53 mutants may confer upon tumor cells a selective survival advantage during chemotherapy. These findings define a new type of mutant p53 selective gain of function, which may compromise the efficacy of cancer chemotherapy.
