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

Although the transcription factor NF-kappaB is most clearly linked to the inhibition of extrinsic apoptotic signals such as TNFalpha by upregulating known anti-apoptotic genes, NF-kappaB has also been proposed to be required for p53-induced apoptosis in transformed cells. However, the involvement of NF-kappaB in this process is poorly understood. Here we investigate this mechanism and show that in transformed MEFs lacking NF-kappaB (p65-null cells) genotoxin-induced cytochrome c release is compromised. To further address how NF-kappaB contributes to apoptosis, gene profiling by microarray analysis of MEFs was performed, revealing that NF-kappaB is required for expression of Noxa, a pro-apoptotic BH3-only protein that is induced by genotoxins and that triggers cytochrome c release. Moreover, we find that in the absence of NF-kappaB, genotoxin treatment cannot induce Noxa mRNA expression. Noxa expression had been shown to be regulated directly by genes of the p53 family, like p73 and p63, following genotoxin treatment. Here we show that p73 is activated after genotoxin treatment only in the presence of NF-kappaB and that p73 induces Noxa gene expression through the p53 element in the promoter. Together our data provides an explanation for how loss of NF-kappaB abrogates genotoxin-induced apoptosis.
