Abstract
Elastin, a fibrous extracellular matrix (ECM) protein, is the main component of elastic fibers that are involved in tissues' elasticity and resilience, enabling them to undergo reversible extensibility and to endure repetitive mechanical stress. After wounding, it is challenging to regenerate elastic fibers and biomaterials developed thus far have struggled to induce its biosynthesis. This review provides a comprehensive summary of elastic fibers synthesis at the cellular level and its implications for biomaterial formulation, with a particular focus on dermal substitutes. The review delves into the intricate process of elastogenesis by cells and investigates potential triggers for elastogenesis encompassing elastin-related compounds, ECM components, and other molecules for their potential role in inducing elastin formation. Understanding of the elastogenic processes is essential for developing biomaterials that trigger not only the synthesis of the elastin protein, but also the formation of a functional and branched elastic fiber network.

[PMID: 34208257 PMCID: PMC8230945 DOI: 10.3390/molecules26123584] [Citation(s) in RCA: 37] [Impact Index Per Article: 12.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2021] [Revised: 06/04/2021] [Accepted: 06/07/2021] [Indexed: 12/11/2022] Open
Abstract
Botanical ingredients have been used for thousands of years in skincare for their convenience as well as the diversity and abundance in compounds with biological activity. Among these, polyphenols and especially flavonoids have gained increasing prominence due to their antioxidant and anti-inflammatory properties. In this study, the most used botanical preparations in anti-aging products marketed in 2011 were determined. The analysis was repeated in 2018 for new and reformulated products. The scientific evidence for their application as active ingredients in anti-aging cosmetics and their flavonoid content was also compiled by searching in online scientific databases. Overall, in 2018, there was a noticeable increase in the use of botanical preparations in anti-aging cosmetics. However, the top three botanical species in both years were Vitis vinifera, Butyrospermum parkii, and Glycine soja, which is consistent with the greater amount of scientific evidence supporting their efficacy. Regarding the function of botanical preparations, there is a clear preference for DNA-protecting ingredients. The most prevalent flavonoids were flavan-3-ols, proanthocyanidins, and anthocyanins. This study provided an updated overview of the market trends regarding the use of botanicals in anti-aging products and documented the state of the art of scientific evidence for the most used plants.

JOURNAL OF ETHNOPHARMACOLOGY 2020; 263:113037. [PMID: 32485302 DOI: 10.1016/j.jep.2020.113037] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/28/2019] [Revised: 02/12/2020] [Accepted: 05/26/2020] [Indexed: 06/11/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Numerous epidemiological and clinical studies have demonstrated the protective role of dietary isoflavones against development of several chronic diseases. ISO-1, one fraction of isoflavone powders derived from soybean cake, is reported to attenuate inflammation and photodamage. AIM OF THE STUDY Contact dermatitis is a common inflammatory skin disease, which accounts for most occupational skin disorders. Instead of oral administration, we aimed to explore the effects of topical ISO-1 application on contact dermatitis by using 2,4-dinitrochlorobenzene (DNCB)-stimulated HaCaT keratinocytes and DNCB-induced mouse dermatitis as models. MATERIALS AND METHODS In the in vitro study, we first evaluated the biologic effects of DNCB on HaCaT keratinocytes. HaCaT keratinocytes were treated with 2,4-dinitrochlorobenzene (DNCB), and cell viability was measured by MTT assay. Then, we detect the prominent induction of IL-8 mRNA expression after DNCB and ISO-1 treatment by reverse transcription polymerase chain reaction (RT-PCR), and release of IL-8 from HaCaT keratinocytes was measured by ELISA assay. HaCaT keratinocytes were pretreated with ISO-1 and then treated with DNCB, phosphorylation of JNK, p38, ERK and IκBα was analyzed by western blot. In the in vivo study, the hairless mice were used for an induced contact dermatitis model. The surface changes in the dorsal skin after DNCB and ISO-1 treatment were recorded using photography, and TEWL, erythema were measured using an MPA-580 cutometer. Blood was also collected from mice for measurement of white blood cell counts. RESULTS Results showed ISO-1 inhibited DNCB-induced IL-8 production and also suppressed DNCB-induced phosphorylation of JNK and p38, and IκBα in HaCaT. In the animal model of DNCB-induced contact dermatitis, topical ISO-1 treatment significantly decreased DNCB-induced erythema and transepidermal water loss (TEWL) in mouse skin. ISO-1 also reduced DNCB-induced skin thickening and increase of white blood cell count. CONCLUSIONS ISO-1 is promising for improvement of DNCB-induced inflammation and skin barrier impairment, suggesting the potential application of topical ISO-1 for inflammatory dermatoses.

J Cosmet Dermatol 2020; 20:2277-2286. [PMID: 33095946 DOI: 10.1111/jocd.13805] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2020] [Revised: 08/31/2020] [Accepted: 10/05/2020] [Indexed: 12/26/2022]
Abstract
BACKGROUND Wrinkles and extracellular matrix (ECM) loss are common signs of skin aging and are thought to be the result of damage caused by reactive oxygen species (ROS); ROS induces an imbalance between ECM degradation and production. OBJECTIVES In this study, we evaluate soy peptides (SP) and collagen peptides (CP), alone and in combination, for their ability to inhibit ROS formation and increase ECM gene expression in order to ameliorate the signs of skin aging. METHODS Using tert-Butyl hydroperoxide (t-BuOOH)-treated dermal fibroblasts, we explored the potential of CP and SP to inhibit ROS formation by flow cytometry, as well as their effect on ECM component genes by real-time quantitative PCR. In addition, we examined the effect of CP and SP on UVA irradiated fibroblasts in a 3D collagen lattice model that measured contractility. RESULTS The results showed that the combination of CP and SP synergistically reduces ROS formation. This combination also increased expression of collagen I, collagen II, elastin, and fibronectin in t-BuOOH-treated or untreated dermal fibroblasts. In the UVA-treated 3D collagen lattice model, the results show that CP and SP significantly improved fibroblast contractility when compared to UVA control (P < 0.05). CONCLUSIONS In conclusion, CP and SP attenuate the loss of contractility due to UVA damage, inhibit t-BuOOH-induced ROS formation, and improve expression of ECM component genes.

Abstract
We developed a novel type of Meju starter culture using single and combined extracts of Allium sativum (garlic clove), Nelumbo nucifera (lotus leaves), and Ginkgo biloba (ginkgo leaves) to improve the quality and functionality of Meju-based fermented products. Meju samples fermented with plant extracts (10 mg/ml) showed phenolic contents of 11.4-31.6 mg/g (gallic acid equivalents). Samples of extracts (garlic clove, lotus leaves, ginkgo leaves and their combination) fermented with Meju strongly inhibited tyrosinase, α-glucosidase, and elastase activities by 36.43-64.34%, 45.08-48.02%, and 4.52-10.90%, respectively. Specifically, ginkgo leaves extract added to fermented Meju samples at different concentrations (1% and 10%) strongly inhibited tyrosinase, α-glucosidase, and elastase activities and exhibited a potent antibacterial effect against Bacillus cereus with a significant reduction in bacterial counts compared with the effects observed for garlic clove and lotus leaf added to Meju samples. Scanning electron microscopy revealed severe morphological alterations of the B. cereus cell wall in response to ginkgo leaf extracts. Gas chromatographic mass spectroscopic analysis of plant extract-supplemented Meju samples and control Meju samples identified 113 bioactive compounds representing 98.44-99.98% total extract. The proposed approach may be useful for the development of various fermented functional foods at traditional and commercial levels.

Abstract
The potential nutricosmetic activities and compositional changes of 80% ethanol extracts of white soybean (MFWS) and black soybean (MFBS) fermented with Monascus pilosus KCCM 60084 at 30°C for 30 days were investigated. Monascus-fermented soybean extracts (MFSEs) showed stronger nutricosmetic potentials in terms of antioxidant as well as tyrosinase and elastase inhibitory activities compared to those of unfermented soybean extracts (p<0.05). Extracts (50mg/mL) from MFBS inhibited the α-melanocyte stimulating hormone (α-MSH)-induced melanogenesis in B16F10 cells more potently than arbutin. HPLC/MS analysis demonstrated that aglycone isoflavones and coenzyme Q10 (CoQ10) levels increased about 33.4- and 3.0-fold in the MFSEs after 20 days of fermentation, respectively. A linear correlation (r 2=0.67 to 0.99) between nutricosmetic activity and concentrations of CoQ10, genistein, and daidzein, which are commonly associated with nutraceutical effects, was observed. Results indicate that Monascus-mediated fermentation can be an efficient strategy to improve nutricosmetic functionality of soybeans.

Abstract
Background Mid-dermal elastolysis (MDE) is a rare, yet well-defined clinical and histopathologic entity manifested by fine wrinkling of the skin and mid-dermal loss of elastic fibers. This disease predominantly affects young to middle-aged Caucasian females and although it has no reported systemic features, it is psychologically bothersome and can be of great cosmetic concern. Methods We report a case of a healthy 45 year-old female with widespread mid-dermal elastolysis. A literature search using the search terms “mid-dermal elastolysis,” “mid dermal elastolysis,” “middermal elastolysis,” and “elastophagocytosis” was conducted on Pubmed, using articles published from January 2008 until November 2014 to accompany Gambichler’s comprehensive 1977 to 2009 review of mid-dermal elastolysis. The references of relevant papers were reviewed and further cases included as appropriate. Results We review the clinical features and histological, ultrastructural, and immunohistochemical findings of MDE, as well as differential diagnoses. There are 13 new publications of MDE since 2008. The novel findings since Gambichler’s review are discussed and pathomechanisms revisited. Interestingly, given the striking female predominance of MDE, there is no known hormonal role in its etiology.

Abstract
UV-induced wrinkle formation owing to the degeneration of the extracellular matrix (ECM) is a major dermatological problem in which abnormal activation of matrix metalloproteinases (MMPs) and elastases have important roles. Heat shock protein 70 (HSP70) has cytoprotective and anti-inflammatory activities. In this study, we examined the effect of HSP70 expression on UV-induced wrinkle formation. Mild heat treatment (exposure to heated water at 42 °C) of the dorsal skin of hairless mice induced the expression of HSP70. The long-term repeated exposure to UV induced epidermal hyperplasia, decreased skin elasticity, degeneration of ECM, and wrinkle formation, which could be suppressed in mice concomitantly subjected to this heat treatment. The UV-induced epidermal hyperplasia, decreased skin elasticity, and degeneration of ECM were less apparent in transgenic mice expressing HSP70 than in wild-type mice. UV-induced fibroblast cell death, infiltration of inflammatory cells, and activation of MMPs and elastase in the skin were also suppressed in the transgenic mice. This study provides evidence for an inhibitory effect of HSP70 on UV-induced wrinkle formation. The results suggest that this effect is mediated by various properties of HSP70, including its cytoprotective and anti-inflammatory activities. We propose that HSP70 inducers used in a clinical context could prove beneficial for the prevention of UV-induced wrinkle formation.

Abstract
Research on aging has run for decades, and knowledge on the biologic process of skin chronological and photoaging is still increasing thanks to read across results generated between human, animal, and in vitro studies. However, wrinkles should not be considered to result only from the aging process. There are few reports on specific wrinkle histological features compared to the surrounding skin, and there is thus a need in really wrinkling skin animal and in vitro models. UV-irradiated Hr mouse is a good model because it develops wrinkles. Nevertheless, as mouse skin is somehow different from human skin, the innovative model of wrinkling human skin xenograft on SCID mice seems to be really promising. Concerning in vitro and ex vivo models, although there have been considerable advances in reconstructing realistic aged skins, there is still a lack of in vitro wrinkling skin model, and unfortunately, this gap will probably be difficult to fill.

Abstract
The non-invasive differentiation of dermal elastic fibres from solar elastosis in vivo is of great interest in dermatologic research, especially for efficacy testing of anti-ageing products. To date, no studies on multiphoton excited fluorescence lifetime characteristics of human elastic fibres and solar elastosis are reported. The goal of the present work was the identification of differential criteria for elastic fibres and solar elastosis by the analysis of fluorescence decay curves acquired by time-correlated single photon counting in vivo multiphoton tomography. For this purpose, fluorescence lifetime measurements (FLIM) were performed with 47 volunteers of different age groups at sun-protected and sun-exposed localizations. Bi-exponential curve fitting was applied to the FLIM data, and characteristic differences between age groups and localizations were found in both relevant fit parameters describing the decay slope. The FLIM analyses have shown that dermal autofluorescence has different lifetimes depending on age and in part on localization.

Abstract
Coenzyme Q(10) (CoQ(10) ) is a well-known antioxidant and has been used in many skincare products for anti-ageing purpose. However, the molecular mechanisms of CoQ(10) function in skin cells are not fully understood. In this paper, we compared the effects of CoQ(10) on primary human dermal fibroblasts from three individuals, including adult. We demonstrated that CoQ(10) treatment promoted proliferation of fibroblasts, increased type IV collagen expression and reduced UVR-induced matrix metalloproteinases-1 (MMP-1) level in embryonic and adult cells. In addition, CoQ(10) treatment increased elastin gene expression in cultured fibroblasts and significantly decreased UVR-induced IL-1α production in HaCat cells. Taken together, CoQ(10) presented anti-ageing benefits against intrinsic ageing as well as photo damage. Interestingly, CoQ(10) was able to inhibit tyrosinase activity, resulting in reduced melanin content in B16 cells. Thus, CoQ(10) may have potential depigmentation effects for skincare.

Abstract
Facial hyperpigmented disorders are a common complaint in the adult population of all races. First-line topical treatments are usually hydroquinone or topical retinoids, which can cause irritant reactions. The need for better tolerated, yet effective, skin lightening agents that could be utilized by a wider population has led to the investigation of several potential botanical/natural compounds. There are currently many topical cosmetic formulations claiming skin depigmenting effects. A few of the ingredients (e.g. soy) are supported not only by in vitro results but also by a body of controlled clinical efficacy studies; other ingredients, instead, are backed mostly by in vitro data and a few small uncontrolled clinical studies. In this review, we describe the most common natural ingredients used for skin depigmentation and their major published studies: soy, licorice extracts, kojic acid, arbutin, niacinamide, N-acetylglucosamine, COFFEEBERRY(™) and green tea.

Abstract
Dermal elastic fibres are extracellular matrix protein complexes produced by fibroblasts and involved in skin elasticity. Elastin fibres decrease with age as a result of reduced synthesis and increased degradation, resulting in skin sagging and reduced skin elasticity. In this study, we show that retinol (ROL), known to enhance dermal collagen production, is also enhancing elastin fibre formation. ROL induced elastin gene expression and elastin fibre formation in cultured human dermal fibroblasts. Topical treatment of cultured human skin explants with a low dose (0.04%) of ROL increased mRNA and protein levels of tropoelastin and of fibrillin-1, an elastin accessory protein, as documented by QPCR and immunohistochemistry staining. Luna staining confirmed the increased elastin fibre network in the ROL-treated skin explants, as compared with untreated controls. These data demonstrate that ROL exerts its anti-ageing benefits not only via enhanced epidermal proliferation and increased collagen production, but also through an increase in elastin production and assembly.

Abstract
The clinical as well as histological data of 79 mid-dermal elastolysis (MDE) patients reported in the literature were evaluated. MDE is an acquired skin condition of the elastic tissue predominantly manifesting on the trunk and proximal extremities of young women. Most commonly observed skin changes include patches of well-circumscribed fine wrinkles (type I) and perifollicular papular protrusions (type II). Rarely, MDE may also occur with persistent reticular erythema and wrinkling (type III). The critical diagnostic histopathological feature of MDE is the selective loss of elastic fibres in the mid-dermis. Mild lymphohistiocytic infiltrates, elastophagocytosis of elastic fibres by macrophages, and even multinucleate giant cells are occasionally observed in MDE lesions. Immunohistological studies and cell culture experiments indicate that dysbalances in elastin turnover are associated with pathological degradative processes including increased elastolytic activity that finally lead to loss of elastic fibres in the mid-dermis. First-line differential diagnoses may include closely related conditions such as anetoderma, annular elastolytic giant cell granuloma, cutis laxa acquisita and pseudoxanthoma elasticum-like papillary dermal elastolysis. Future therapeutic approaches in MDE patients should focus on agents that are able to block increased elastase activity and induce elastin synthesis.
