PFN1 and integrin-β1/mTOR axis involvement in cornea differentiation of fibroblast limbal stem cells.
Article in Journal of cellular and molecular medicine, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Ex vivo limbal stem cell transplantation is the main therapeutic approach to address a complete and functional re-epithelialization in corneal blindness, the second most common eye disorder. Although important key points were defined, the molecular mechanisms involved in the epithelial phenotype determination are unclear. Our previous studies have demonstrated the pluripotency and immune-modulatory of fibroblast limbal stem cells (f-LSCs), isolated from the corneal limbus. We defined a proteomic profile especially enriched in wound healing and cytoskeleton-remodelling proteins, including Profilin-1 (PFN1). In this study we postulate that pfn-1 knock down promotes epithelial lineage by inhibiting the integrin-β1(CD29)/mTOR pathway and subsequent NANOG down-expression. We showed that it is possible modulate pfn1 expression levels by treating f-LSCs with Resveratrol (RSV), a natural compound: pfn1 decline is accompanied with up-regulation of the specific differentiation epithelial genes pax6 (paired-box 6), sox17 (sex determining region Y-box 17) and ΔNp63-α (p63 splice variant), consistent with drop-down of the principle stem gene levels. These results contribute to understand the molecular biology of corneal epithelium development and suggest that pfn1 is a potential molecular target for the treatment of corneal blindness based on epithelial cell dysfunction.
