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

backgroundTissue expansion is a widely employed technique in reconstructive surgery aimed at addressing considerable skin defects. Nevertheless, matters like inadequate expansion capability and the potential for skin breakage due to the fragility of the expanded tissue present notable hurdles in enhancing skin regeneration during this process. Angiotensin-converting enzyme 2 (ACE2) is recognized for its essential role in facilitating tissue renewal and regeneration. However, its precise impact on skin renewal during tissue expansion remains underexplored. This study seeks to elucidate ACE2's contribution to skin regeneration, specifically examining its role in collagen synthesis.

methodsThis study evaluated the expression and distribution of ACE2 in expanded skin using samples derived from both rats and human patients. Additionally, we investigated ACE2 expression in stretched keratinocytes in vitro. ACE2 knockout keratinocytes were transfected with small interfering RNA (siRNA) and cocultured with fibroblasts to observe fibroblast proliferation and migration. MLN-4760 was utilized to inhibit the ACE2 enzymatic activity. Additionally, we analyzed parameters such as the size of expanded skin, dermal thickness, and the levels of collagen I (COL I), collagen III (COL III), and transforming growth factor β (TGF-β) to elucidate the role of ACE2 in the context of expanded skin.

resultsThe thinning of the expanded dermis was linked with elevated ACE2 expression. Enzymatic activity and ACE2 expression were both increased by mechanical stress. Additionally, ACE2 utilized Ang II to activate the migration and proliferation of human dermal fibroblasts. In vivo, the ACE2 inhibitor MLN-4760 promoted skin regeneration and reduced dermal thinning by elevating COL I, COL III, and TGF-β during expansion.

conclusionsThis finding suggest that mechanical stretch increases ACE2 expression, which in turn promotes the regeneration of expanded skin. The basis for using ACE2 in clinical settings to increase tissue expansion efficacy is provided by this work.
