Fibroblast Angiotensin II Type 1a Receptors Contribute to Angiotensin II-Induced Medial Hyperplasia in the Ascending Aorta.

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
objectiveAngiotensin II (Ang II) infusion causes aortic medial thickening via stimulation of angiotensin II type 1a (AT1a) receptors. The purpose of this study was to determine the cellular loci of AT1a receptors that mediate this Ang II-induced aortic pathology. APPROACH AND
resultsSaline or Ang II was infused into AT1a receptor floxed mice expressing Cre under control of cell-specific promoters. Initially, AT1a receptors were depleted in aortic smooth muscle cell and endothelium by expressing Cre under control of SM22 and Tie2 promoters, respectively. Deletion of AT1a receptors in either cell type had no effect on Ang II-induced medial thickening. To determine whether this effect was related to neural stimulation, AT1a receptors were depleted using an enolase 2-driven Cre. Depletion of AT1a receptors in neural cells attenuated Ang II-induced medial thickening of the ascending, but not descending aorta. Lineage tracking studies, using ROSA26-LacZ, demonstrated that enolase 2 was also expressed in adventitial cells adjacent to the region of attenuated thickening. To determine whether adventitial fibroblasts contributed to this attenuation, AT1a receptors in fibroblasts were depleted using S100A4 driven Cre. Similar to enolase 2-Cre, Ang II-induced medial thickening was attenuated in the ascending, but not the descending aorta. Lineage tracking demonstrated an increase of S100A4-LacZ positive cells in the media of the ascending region during Ang II infusion.
conclusionsAT1a receptor depletion in fibroblasts attenuates Ang II-induced medial hyperplasia in the ascending aorta.
