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

p53 inactivation is often observed in Burkitt's lymphoma (BL) cells, because of either mutations in p53 gene or an overexpression of the p53-negative regulator MDM2. Epstein-Barr virus (EBV) is present in virtually 100% of BL cases occurring in endemic areas, but in only 10-20% of sporadic cases. In EBV(-) BL cells, reactivation of p53, induced by reducing MDM2 protein level, led to apoptosis. We show here that nutlin-3, a potent antagonist of MDM2, activates the p53 pathway in all BL cell lines harboring wild-type p53, regardless of EBV status. However, nutlin-3 strongly induced apoptosis in EBV(-) or latency I EBV(+) cells, whereas latency III EBV(+) cells were much more resistant. Prior treatment with sublethal doses of nutlin-3 sensitizes EBV(-) or latency I EBV(+) cells to apoptosis induced by etoposide or melphalan, but protects latency III EBV(+) cells. p21(WAF1) which is overexpressed in the latter, is involved in this protective effect, as siRNA-mediated inhibition of p21(WAF1) restores sensitivity to etoposide. Nutlin-3 protects latency III BL cells by inducing a p21(WAF1)-mediated G1 arrest. Most BL patients with wild-type p53 tumors could therefore benefit from treatment with nutlin-3, after a careful determination of the latency pattern of EBV in infected patients.
