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

CCAAT/enhancer-binding protein alpha (C/EBPalpha) is mutated in 10% of acute myeloid leukemias, resulting in either a truncated protein or an altered leucine zipper (C/EBPalphaLZ) that prevents DNA binding. C/EBPalpha induces bcl-2 in cooperation with nuclear factor-kappaB (NF-kappaB) p50 to inhibit apoptosis. We now demonstrate that C/EBPalpha or a C/EBPalphaLZ oncoprotein binds the bcl-2 P2 promoter in chromatin immunoprecipitation assays and induces the promoter dependent on the integrity of a kappaB site. C/EBPalpha expressed as a transgene in B cells binds and activates the bcl-2 promoter, but not in nfkb1-/- mice lacking NF-kappaB p50. Bcl-2 is central to the intrinsic apoptotic pathway, whereas FLICE inhibitory protein (FLIP) modulates caspase-8, the initiator caspase of the extrinsic pathway. C/EBPalpha and C/EBPalphaLZ also bind the FLIP promoter and induce its expression dependent upon NF-kappaB p50. Moreover, induction of FLIP by C/EBPalpha protects splenocytes from Fas ligand-induced apoptosis, but only if p50 is present. We also demonstrate the direct interaction between bacterially produced C/EBPalpha and NF-kappaB p50, mediated by the C/EBPalpha basic region. These findings indicate that C/EBPalpha or its oncoproteins activate the bcl-2 and FLIP genes by tethering to their promoters through bound NF-kappaB p50. Targeting their interaction may favor apoptosis of transformed cells.
