Background: Recent in vitro and in vivo studies have suggested that the elastin peptide improves the skin's biophysical properties, enhancing the proliferation of fibroblasts and elastin synthesis, resulting in anti-aging properties. Therefore, we conducted a randomized, double-blinded, placebo-controlled study to clinically evaluate the effect of elastin peptide intake on human skin.
Materials And Methods: Healthy adult participants (N = 100) were randomly assigned to receive a test product containing 100 mg of Bonito elastin peptide (VGPG Elastin ) or placebo. In this study, all participants were Asian from Korea. The parameters of skin wrinkles, hydration, and brightening (melanin index) were measured at baseline and 4, 8, and 12 weeks after intervention.
Results: The average skin roughness, maximum peak-to-valley values, maximum peak height of the wrinkle, maximum valley depth of the wrinkle, average maximum height of the wrinkle, and eye wrinkle volume improved considerably in the test group compared with the placebo after 12 weeks of intervention. Skin hydration was enhanced, and the melanin index was significantly lower in the test group than in the placebo group. No participant experienced adverse events related to the test product.
Conclusion: Oral consumption of Bonito elastin peptide (VGPG Elastin®) reduced fine wrinkles, enhanced skin moisture, and decreased melanin index without significant adverse effects and may be a promising anti-wrinkle, anti-dryness, and anti-pigmentation treatment.

This study tested the hypothesis that diabetic wound treatment with biomimetic pro-angiogenic, proteolytically and mechanically stable RADA16-II peptide nanofibers promotes regenerative wound healing via attenuation of inflammation and stimulation of neovascularization. Two full-thickness excisional dorsal skin wounds were created on 8-10 week old female db/db mice and treated with nanofiber hydrogel or saline (control). Animals were euthanized on days 7, 14, 28, and 56 and their wounds were analysed for morphology, vascularization, strength, and inflammation.

Medical devices such as vascular grafts, stents, and catheters are crucial for patient treatment but often suffer suboptimal integration with host tissues due to the nature of their surfaces. The materials commonly used, including metals and synthetic polymers, frequently lead to undesired immune responses and device failure. In this context, coating their surfaces with designer proteins has arisen as a promising strategy to improve the device's biointegration.

Abdominal aortic aneurysm (AAA) is a life-threatening vascular disease characterized by chronic inflammation, extracellular matrix degradation, and smooth muscle cell apoptosis. (), a key periodontal pathogen, has been implicated in the progression of cardiovascular diseases, including AAA, but the underlying mechanisms remain unclear. In this study, we investigated the role of GroEL, a bacterial heat shock protein 60 homolog derived from , in AAA development.

Precise control of protein translocation is essential for synthetic biology and protein engineering. Here, we present a temperature-responsive system using elastin-like polypeptides (ELPs) to regulate the translocation of a conditionally lethal enzyme in . The enzyme, levansucrase, whose activity becomes lethal in the presence of sucrose, was engineered with an N-terminal signal peptide and a C-terminal ELP tag.

Injectable hydrogels are promising biomaterials for tissue engineering applications due to their ability to deliver bioactive compounds or cells with minimal invasiveness. Temperature-responsive in situ gelling hydrogels, which undergo transition from liquid to gel in response to temperature stimuli, are desirable candidates for injectable hydrogels. Elastin-like polypeptides (ELPs) are well-known temperature-responsive biomaterials for cell scaffolds, drug delivery, and tissue engineering, due to their biocompatibility, biodegradability, and tunable mechanical properties.
