The Long Noncoding RNA H19 Promotes Fibrotic Processes in Lens Epithelial Cells.

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
Purpose: The purpose of this study was to investigate the role of lncRNA H19 in epithelial-mesenchymal transition (EMT) and its molecular mechanism in fibrotic cataracts. Methods: TGF-β2-induced EMT was induced in human lens epithelial cell line (HLECs) and rat lens explants to mimic posterior capsular opacification (PCO) in vitro and in vivo. Anterior subcapsular cataract (ASC) was induced in C57BL/6J mice. The long noncoding RNA (lncRNA) H19 (H19) expression was detected by RT-qPCR. Whole-mount staining of lens anterior capsule was used to detect α-SMA and vimentin. Lentiviruses carrying shRNA or H19 vector were transfected in HLECs to knockdown or overexpress H19. Cell migration and proliferation were characterized by EdU, Transwell, and scratch assay. EMT level was detected by Western blotting and immunofluorescence. The rAAV2 carrying mouse H19 shRNA was injected into ASC model mouse anterior chambers as a gene therapy to determine its therapeutic potential. Results: PCO and ASC models were built successfully. We found H19 upregulation in PCO and ASC models in vivo and in vitro. Overexpression of H19 by lentivirus transfection increased cell migration, proliferation, and EMT. In addition, H19 knockdown by lentivirus suppressed cell migration, proliferation, and EMT levels in HLECs. Moreover, transfection of rAAV2 H19 shRNA alleviated fibrotic area in ASC mouse lens anterior capsules. Conclusions: Excessive H19 participates in lens fibrosis. Overexpression of H19 increases, whereas knockdown of H19 ameliorates HLECs migration, proliferation, and EMT. These results demonstrate H19 might be a potential target for fibrotic cataracts.
