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

Disturbances of circadian rhythms and mammalian clock genes have been implicated in the etiologies of many chronic illnesses, including cancer. We show that transcription factor CCAAT/enhancer-binding protein alpha (C/EBPalpha)-regulated PER2 activation is a potential tumor suppressor pathway in diffuse large B-cell lymphoma (DLBCL), one of the commonest types of mature B-cell lymphoma. Expression analysis of human B-cell lymphoma samples including DLBCL (n = 50), mantle cell (n = 21), follicular (n = 25) and Burkitt (n = 18) lymphoma revealed markedly down-regulated CEBPA and PER2 mRNA levels exclusively in DLBCL samples compared to control lymphatic tissue. We demonstrated direct regulation of the circadian core clock gene PER2 by C/EBPalpha in the pro-B cell line Ba/F3, and forced expression of PER2 resulted in decreased proliferation, G0/G1 cell cycle arrest and increased rates of apoptosis. Interestingly, treatment of human DLBCL cell lines with the histone deacetylase-inhibitor suberoylanilide hydroxamic acid (SAHA) significantly increased the expression of C/EBPalpha and Per2, accompanied by cell growth inhibition; in contrast, siRNA knockdown of CEBPA reduced the anti-proliferative effect of SAHA treatment. Our results show for the first time that C/EBPalpha with its associated direct core clock gene target, PER2, are highly deregulated in DLBCL, suggesting an important tumor suppressive pathway in the pathogenesis of this lymphoma entity.
