Age-related changes in cardiac expression of VEGF and its angiogenic receptor KDR in stroke-prone spontaneously hypertensive rats.
Article in Molecular and cellular biochemistry, 2005. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
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
We examined the age-related changes in cardiac expression of angiogenic molecules during the development of cardiac remodeling in stroke-prone spontaneously hypertensive rats (SHRSP) in comparison with those in Wistar-Kyoto rats (WKY) and spontaneously hypertensive rats (SHR). Vascular endothelial growth factor (VEGF) was highly upregulated in SHRSP aged 20 weeks compared with the same age of WKY, but it was downregulated at 40 weeks. On the other hand, KDR, an angiogenic receptor of VEGF, and endothelial nitric oxide synthase, which is important in the VEGF-mediated angiogenic pathway, were markedly downregulated in SHRSP from 20 weeks of age. Such age-related changes in their expression levels seen in SHRSP were quite different from those in SHR. In both SHR and SHRSP, transforming growth factor-beta1 (TGF-beta1) expression was increased with age, although SHRSP showed more marked upregulation. Cardiac remodeling in SHRSP was characterized by decreased coronary capillary density, cardiomyocyte hypertrophy, and cardiac fibrosis. We conclude that, in addition to overexpression of TGF-beta1, which appears to play a pivotal role in promoting cardiac hypertrophy and fibrosis, a defect of the VEGF-KDR system could result in impaired physiologic coronary angiogenesis in SHRSP, contributing to cardiac deteroration associated with myocardial ischemia in this malignant hypertensive model.
