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

E2F is a heterodimeric transcription factor composed of one of five E2F subunits (E2F-1 to E2F-5) and a DP subunit. E2F regulates the expression of several growth-promoting genes, and thus, can be a target of antiproliferative action of interferons (IFNs). In this study, we investigated the mechanisms whereby IFN-alpha suppresses transcription of the E2F-1 gene. Transfection studies revealed that E2F-1 promoter was functionally divided into two parts: upstream activation sequences (UAS) and a downstream negative-regulatory element (E2F-binding sites). When cells were proliferating, transcription of the E2F-1 gene was primarily driven by the UAS, while E2F sites were not involved in activation. IFN-alpha markedly reduced E2F-1 promoter activity, but introduction of non-binding mutation at the E2F sites completely abrogated the inhibition. Free E2F4 was found to be the predominant species bound to the E2F sites in proliferating cells. IFN-alpha induced upregulation of E2F-4 along with dephosphorylation of pRB and p130, which resulted in the formation of E2F-4/pRB and E2F-4/p130 complexes on the E2F-1 promoter. These complexes function as transcriptional repressors to inhibit E2F-1 mRNA expression. Our findings indicate that E2F-4 is a critical regulator of E2F-1, which offer an excellent paradigm for understanding functional diversity within the E2F family.
