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

The human vascular endothelial growth factor (VEGF) promoter contains a polypurine/polypyrimidine (pPu/pPy) tract that is known to play a critical role in its transcriptional regulation. This pPu/pPy tract undergoes a conformational transition between B-DNA, single-stranded DNA, and atypical secondary DNA structures such as G-quadruplexes and i-motifs. We studied the interaction of the cytosine-rich (C-rich) and guanine-rich (G-rich) strands of this tract with transcription factors heterogeneous nuclear ribonucleoprotein (hnRNP) K and nucleolin, respectively, both in vitro and in vivo and their potential role in the transcriptional control of VEGF. Using chromatin immunoprecipitation (ChIP) assay for our in vivo studies and electrophoretic mobility shift assay (EMSA) for our in vitro studies, we demonstrated that both nucleolin and hnRNP K bind selectively to the G- and C-rich sequences, respectively, in the pPu/pPy tract of the VEGF promoter. The small interfering RNA (siRNA)-mediated silencing of either nucleolin or hnRNP K resulted in the down-regulation of basal VEGF gene, suggesting that they act as activators of VEGF transcription. Taken together, the identification of transcription factors that can recognize and bind to atypical DNA structures within the pPu/pPy tract will provide new insight into mechanisms of transcriptional regulation of the VEGF gene.
