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

aimsEndothelial colony forming cells (ECFCs) participate in post-natal vasculogenesis. We previously reported that vascular endothelial growth factor (VEGF) promotes human ECFC differentiation through AMP-activated protein kinase (AMPK) activation. However, the mechanisms underlying transcriptional regulation of ECFC differentiation still remain largely elusive. Here, we investigated the role of transcription factor Krüppel-like factor 2 (KLF2) in the regulation of ECFC function. METHODS AND

resultsHuman ECFCs were isolated from cord blood and cultured. Treatment with VEGF significantly increased endothelial markers in ECFCs and their capacity for migration and tube formation. The mRNA and protein levels of KLF2 were also significantly up-regulated. This up-regulation was abrogated by AMPK inhibition or by knockdown of KLF2 with siRNA. Furthermore, adenovirus-mediated overexpression of KLF2 promoted ECFC differentiation by enhancing expression of endothelial cell markers, reducing expression of progenitor cell markers, and increasing the capacity for tube formation in vitro, indicating the important role of KLF2 in ECFC-mediated angiogenesis. Histone deacetylase 5 (HDAC5) was phosphorylated by AMPK activity induced by VEGF and the AMPK agonist AICAR (5-amino-1-β-D-ribofuranosyl-imidazole-4-carboxamide). In vivo angiogenesis assay revealed that overexpression of KLF2 in bone-marrow-derived pro-angiogenic progenitor cells promoted vessel formation when the cells were implanted in C57BL/6 mice.

conclusionUp-regulation of KLF2 by AMPK activation constitutes a novel mechanism of ECFC differentiation, and may have therapeutic value in the treatment of ischaemic heart disease.
