Wrinkle-Improving Effect of Novel Peptide That Binds to Nicotinic Acetylcholine Receptor.
Article in International journal of molecular sciences, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Wrinkles, one of the most common signs of aging, are primarily caused by the continuous contraction of muscles. Muscle contraction is induced by the binding of acetylcholine (ACh), released at the neuromuscular junction, to nicotinic acetylcholine receptor (nAChR) present on the muscle cell surface. In this study, we aimed to develop a wrinkle-improving peptide that inhibits the binding of ACh to nAChR using peptide phage display technology. Our peptide showed a remarkably high binding affinity to nAChR subunit α1, with a value below 1 µM, and was found to inhibit the action of ACh through its interaction with these receptors. Furthermore, it increased collagen synthesis in skin cells and upregulated the expression of the aquaporin-3 (AQP3) and hyaluronan synthase-2 (HAS2) genes. These results confirm that the peptide effectively inhibits muscle contraction and enhances skin elasticity and hydration, contributing to its wrinkle-reducing effects. Clinical studies on humans observed significant improvement in wrinkles after three weeks of use, with substantial reduction observed after six weeks. In conclusion, these findings demonstrate the efficacy of the peptide (named Medipep) in reducing wrinkles.
