All-trans retinoic acid regulates the expression of MMP-2 and TGF-β2
Article in International journal of ophthalmology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
aimTo investigate the effect of all-trans retinoic acid (ATRA) on retinol dehydrogenase 5 (RDH5), matrix metalloproteinase-2 (MMP-2) and transforming growth factor-β2 (TGF-β2) transcription levels, and the effect of RDH5 on MMP-2 and TGF-β2 in retinal pigment epithelium (RPE) cells.
methodsAfter adult RPE cell line-19 (ARPE-19 cells) intervened with gradient concentrations of ATRA (0-20 µmol/L) for 24h, flow cytometry was used to detect the proliferation and apoptosis of cells in each group, and quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect RDH5, MMP-2 and TGF-β2 mRNA expression. Then, after ARPE-19 cells transfected with three different siRNA targets for 48h, the RDH5 knockdown efficiency of each group and expression of MMP-2 and TGF-β2 mRNA within them was detected by qRT-PCR.
resultsFlow cytometry results showed that ATRA could inhibit the proliferation of RPE cells and promote the apoptosis of RPE cells, and the difference of apoptosis was statistically significant when the ATRA concentration exceeded 5 µmol/L and compared with the normal control group (
conclusionATRA inhibits the expression of RDH5 and promotes MMP-2 and TGF-β2, and further RDH5 knockdown significantly upregulates MMP-2 and TGF-β2. These findings suggest that RDH5 may be involved in an epithelial-mesenchymal transition of RPE cells mediated by ATRA.
