Novel insights into the angiogenic function of JMJD2B in diabetic hind limb ischemia: involvement of activating Wnt/β-catenin pathway.

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.
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
Critical limb ischemia (CLI) is a major health problem, in which diabetes is a risk factor. Lysine Demethylase 4B (JMJD2B) is a histone demethylase. Diabetic CLI model was established in mice by streptozotocin injection and femoral artery ligation. Reduced expression of JMJD2B in lower limb muscles was observed in CLI mice with or without diabetes, accompanied by impaired blood perfusion and mobility. Adenovirus-mediated JMJD2B overexpression improved blood perfusion and angiogenesis as indicated by the alternation in CD31, α-SMA, and VEGFA expression in the lower limb of diabetic mice with CLI. In vitro, JMJD2B expression and the proliferation and tube formation ability were inhibited by high glucose and ischemic conditions in HMEC-1 cells. Overexpressed-JMJD2B contributed to angiogenesis by promoting cell proliferation, migration, and tube formation of HMEC-1 cells, as well as increasing VEGFA and SDF-1 expression. Mechanism study indicated that JMJD2B overexpression activated the Wnt/β-catenin pathway by promoting β-catenin nuclear translocation and the expression. This might lead to stimulated angiogenesis, as demonstrated by the Wnt/β-catenin inhibitor XAV-939. Overall, our study revealed that JMJD2B was down-regulated in CLI mice with diabetes and JMJD2B overexpression promoted angiogenesis probably via the activation of Wnt/β-catenin pathway.
