Severing AL, Rembe JD, Füllerer M, Stürmer EK. Impact of the chronic wound microenvironment and marine omega-3 fatty acids on skin cell regeneration processes. Exp Dermatol 2021; 31:725-735. [PMID: 34821420 DOI: 10.1111/exd.14506] [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: 11/19/2020] [Revised: 11/07/2021] [Accepted: 11/22/2021] [Indexed: 01/04/2023]
Abstract
Marine long-chain omega-3 polyunsaturated fatty acids (ω3 FA) are involved in numerous cell responses and therefore vital for the mammal organism. Because of the attribution of immunomodulatory effects, a favourable impact on the inflammatory response in chronic wounds and cells involved in wound healing can be suspected. In the experimental setup, docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) were investigated regarding their impact on metabolic activity, cell proliferation and migration of human keratinocytes (HaCaT) and newborn foreskin fibroblasts (CRL-2522). For simulation of the microenvironment of a chronic wound, human chronic wound fluid (CWF) was used in the experimental setup addressing the in vitro influence of DHA, EPA and CWF on regenerative processes. The results showed a significant increase in the metabolic activity of keratinocytes and fibroblasts after 72 h treatment with DHA and EPA. In contrast, treatment with ω3 FA had no significant positive effect on skin cell proliferation. Both ω3 FA had no influence on in vitro wound closure. CWF demonstrated significantly adverse effects, which ω3 FA were unable to mitigate. It can be concluded that CWF exhibited the expected adverse effect on both skin cell types, especially inhibiting in vitro wound closure. ω3 FAs showed a slightly positive, yet rarely significant effect on human skin cells. Overall, the addition of DHA or EPA showed no relevant benefit for skin cells challenged with human CWF, merely in combination with DHA an initial significant increase in cell metabolism (fibroblasts) and cell proliferation (keratinocytes) could be observed.

Food Sci Nutr 2021; 9:3693-3700. [PMID: 34262728 PMCID: PMC8269668 DOI: 10.1002/fsn3.2330] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2020] [Revised: 03/25/2021] [Accepted: 04/25/2021] [Indexed: 12/14/2022] Open
Abstract
N-3 polyunsaturated fatty acids (n-3 PUFA) can alleviate ultraviolet B (UVB)-induced skin cancers, but their effects on sunburn and upcoming wound healing remain controversial. This study aimed to explore the impact of n-3 PUFA-enriched fish oil (n-3 PUFA-FO) on UVB-induced sunburns and subsequent healing. Sixty C57BL/6 female mice were divided into two groups. The treated group mice were fed n-3 PUFA-FO for the entire duration of the experiment. Mice in the control group were fed a standard diet. After two weeks of n-3 PUFA-FO feeding, mice were exposed to UVB for 20 min and sacrificed 20 d later. Skin photodamage and lesion area were recorded during wound healing. Epidermal lesion thickness was quantified in hematoxylin and eosin-stained skin sections. Inflammation and macrophage polarization were assessed by qRT-PCR. Oxidative stress and antioxidant enzyme activity were quantified using specific ELISA kits. N-3 PUFA-FO feeding decreased UVB photodamage and accelerated wound healing progression, both of which were coupled with less intense inflammation and increased macrophage M2 phenotype polarization. Furthermore, n-3 PUFA-FO brought about a decrease in malondialdehyde (MDA) levels but increased the activity of catalase (CAT) and glutathione peroxidase (GP), without changing superoxide dismutase (SOD) activity. N-3 PUFA-FO protects against UVB-induced skin photodamage and promotes wound healing by modulating macrophage phenotypic polarization and antioxidant enzyme activities. N-3 PUFA-FO could be a novel therapeutic approach for both the prevention and treatment of sunburns.

[PMID: 31657094 DOI: 10.1002/ptr.6524] [Citation(s) in RCA: 28] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2019] [Revised: 08/13/2019] [Accepted: 09/21/2019] [Indexed: 12/13/2022]
Abstract
The use of vegetable butters and oils shows promising results in the treatment of skin wounds, as they have an effective impact on the phases of the wound-healing process through their antimicrobial, anti-inflammatory, and antioxidative activities and by promoting cell proliferation, increasing collagen synthesis, stimulating dermal reconstruction, and repairing the skin's lipid barrier function. In this article, in vitro and in vivo studies of argan (Argania spinosa), avocado (Persea americana), black cumin (Nigella sativa), calophyllum (Calophyllum inophyllum), coconut (Cocos nucifera), cranberry (Vaccinium macrocarpon), grape (Vitis vinifera), green coffee (Coffea arabica), lentisk (Pistacia lentiscus), linseed (Linum usitatissimum), lucuma (Pouteria lucuma), mango (Mangifera indica), olive (Olea europaea), pomegranate (Punica granatum), pumpkin (Cucurbita pepo), rapeseed (Brassica napus), sea buckthorn (Hippophae rhamnoides), and sunflower (Helianthus annuus) oils were reviewed. In many cases, vegetable oils proved to be more effective than synthetic wound-healing compounds used as controls. The fatty-acid components of vegetable oils are assumed to play a major role in the wound-healing process, in particular polyunsaturated fatty acids such as linoleic acid. Evidence shows that oils with a higher linoleic to oleic acid ratio are more effective for lipid barrier repair. However, in depth studies are needed to gain knowledge about vegetable oils' effects on the skin and vice versa.

Abstract
Fatty acids (FAs) are potent organic compounds that not only can be used as an energy source during nutrient deprivation but are also involved in several essential signaling cascades in cells. Therefore, a balanced intake of different dietary FAs is critical for the maintenance of cellular functions and tissue homeostasis. A diet with an imbalanced fat composition creates a risk for developing metabolic syndrome and various musculoskeletal diseases, including osteoarthritis (OA). In this review, we summarize the current state of knowledge and mechanistic insights regarding the role of dietary FAs, such as saturated FAs, omega-6 polyunsaturated FAs (PUFAs), and omega-3 PUFAs on joint inflammation and OA pathogeneses. In particular, we review how different types of dietary FAs and their derivatives distinctly affect a variety of cells within the joint, including chondrocytes, osteoblasts, osteoclasts, and synoviocytes. Understanding the molecular mechanisms underlying the effects of FAs on metabolic behavior, anabolic, and catabolic processes, as well as the inflammatory response of joint cells, may help identify therapeutic targets for the prevention of metabolic joint diseases.

Abstract
Objective The maintenance of youthful skin appearance is strongly desired by a large proportion of the world's population. The aim of the present study was therefore to evaluate the effect on skin wrinkling, of a combination of ingredients reported to influence key factors involved in skin ageing, namely inflammation, collagen synthesis and oxidative/UV stress. A supplemented drink was developed containing soy isoflavones, lycopene, vitamin C and vitamin E and given to post-menopausal women with a capsule containing fish oil. Method We have performed a double-blind randomized controlled human clinical study to assess whether this cocktail of dietary ingredients can significantly improve the appearance of facial wrinkles. Results We have shown that this unique combination of micronutrients can significantly reduce the depth of facial wrinkles and that this improvement is associated with increased deposition of new collagen fibres in the dermis. Conclusion This study demonstrates that consumption of a mixture of soy isoflavones, lycopene, vitamin C, vitamin E and fish oil is able to induce a clinically measureable improvement in the depth of facial wrinkles following long-term use. We have also shown, for the first time with an oral product, that the improvement is associated with increased deposition of new collagen fibres in the dermis. Résumé
