1 · What the graph read from it

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.

2 · The registry

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

backgroundDespite advancements in dental therapies, insufficient gingival tissue remains a significant challenge. Currently, no specific medications promote the regeneration of gingival tissue, with existing treatments primarily redistributing tissue rather than restoring it. Amphibian bioactive peptides show promise but remain underexplored in gingival repair. This study investigates the potential of RL-RF10, a peptide derived from frogs, for gingival tissue repair.

methodsThe localization of RL-RF10 was monitored using fluorescein isothiocyanate labelling. The effects of RL-RF10 on the biological characteristics of human oral keratinocytes were investigated through live/dead staining, cell counting kit-8 assays, cell cycle analysis, and wound healing assays. Additionally, the role of integrins (ITG) and epithelial-mesenchymal transition in cell migration, as well as the impact of signalling pathways involved in cell migration, was studied through Western blot and immunofluorescence assays. The efficacy of RL-RF10 was assessed using a New Zealand rabbit gingival defect model in vivo.

resultsRL-RF10 exhibited good biocompatibility and promoted cell proliferation and migration. It enhances cell migration capabilities by activating the p38 mitogen-activated protein kinases signalling pathway, upregulating the expression of ITG αv and β3. The gingival tissue of rabbits treated with RL-RF10 displayed superior tissue structure and repair outcomes.

conclusionsRL-RF10 is the first known amphibian-derived peptide with potential for gingival repair and regeneration. It promotes cell migration, a process linked to p38 mitogen-activated protein kinases pathway activation and associated with the upregulation of ITG αvβ3 expression and partial epithelial-mesenchymal transition. These findings provide insights into RL-RF10's role in tissue repair and suggest new avenues for clinical applications.
