Ezrin Regulating the Cytoskeleton Remodeling is Required for Hypoxia-Induced Myofibroblast Proliferation and Migration.
Article in Frontiers in cardiovascular medicine, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
backgroundHypoxia pulmonary arterial hypertension (HPAH) is a disease of the small vessels characterized by sustained vasoconstriction, thickening of arterial walls, vascular remodeling, and progressive increase in pulmonary vascular resistance, thus leading to right heart failure and finally death. Recent evidence demonstrated that massive pulmonary artery smooth muscle-like cells (PASMLCs) accumulating in the intima might also be developed from the differentiation of pulmonary myofibroblast (PMF) of tunica media. And PMF appeared the phenomenon of the cytoskeleton remodeling. So, it would be important in the clarification of the pivotal factors controlling this cytoskeleton structure change.
methodsPMFs were cultured from the normal rats and then divided into three groups and incubated by normal or hypoxic conditions respectively. mRNA level was evaluated by real-time reverse transcription polymerase chain reaction, and protein expression was detected by western blot. Cell proliferation was determined by the MTT and thymidine incorporation assay.
resultsHere, we report that the hypoxia increased the expression levels of ezrin mRNA and protein in PMFs, which might explain that the expression of cytoskeletal proteins (destrin, a1-actin, and a1-tubulin) in PMFs was significantly induced by hypoxia. After inhibiting ezrin in PMFs by siRNA transfection, we found the over-expression of cytoskeletal proteins induced by hypoxia was significantly suppressed at all time-points. Additionally, we found that hypoxia or over-expression of ezrin through adenovirus-mediated ezrin gene transfection significantly increases the proliferation and migration of PMFs, and which could be inverted by the transfection of siRNA.
conclusionThese findings suggest that ezrin regulating of aberrant dysregulation of cytoskeletal proteins may be the major cause of PMFs' proliferation and migration under the condition of hypoxia and may, therefore, play a fundamental role in the accumulation of PASMLCs of HPAH.
