Enhanced Wound Healing Potential of Spirulina platensis Nanophytosomes: Metabolomic Profiling, Molecular Networking, and Modulation of HMGB-1 in an Excisional Wound Rat Model. Mar Drugs 2023; 21:md21030149. [PMID: 36976198 PMCID: PMC10051127 DOI: 10.3390/md21030149] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2023] [Revised: 02/17/2023] [Accepted: 02/21/2023] [Indexed: 03/03/2023] Open
Abstract
Excisional wounds are considered one of the most common physical injuries. This study aims to test the effect of a nanophytosomal formulation loaded with a dried hydroalcoholic extract of S. platensis on promoting excisional wound healing. The Spirulina platensis nanophytosomal formulation (SPNP) containing 100 mg PC and 50 mg CH exhibited optimum physicochemical characteristics regarding particle size (598.40 ± 9.68 nm), zeta potential (−19.8 ± 0.49 mV), entrapment efficiency (62.76 ± 1.75%), and Q6h (74.00 ± 1.90%). It was selected to prepare an HPMC gel (SPNP-gel). Through metabolomic profiling of the algal extract, thirteen compounds were identified. Molecular docking of the identified compounds on the active site of the HMGB-1 protein revealed that 12,13-DiHome had the highest docking score of −7.130 kcal/mol. SPNP-gel showed higher wound closure potential and enhanced histopathological alterations as compared to standard (MEBO® ointment) and S. platensis gel in wounded Sprague-Dawley rats. Collectively, NPS promoted the wound healing process by enhancing the autophagy process (LC3B/Beclin-1) and the NRF-2/HO-1antioxidant pathway and halting the inflammatory (TNF-, NF-κB, TlR-4 and VEGF), apoptotic processes (AIF, Caspase-3), and the downregulation of HGMB-1 protein expression. The present study’s findings suggest that the topical application of SPNP-gel possesses a potential therapeutic effect in excisional wound healing, chiefly by downregulating HGMB-1 protein expression.

Intermediate Hair Follicles from Patients with Female Pattern Hair Loss Are Associated with Nutrient Insufficiency and a Quiescent Metabolic Phenotype. Nutrients 2022; 14:3357. [PMID: 36014862 PMCID: PMC9416027 DOI: 10.3390/nu14163357] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2022] [Revised: 08/10/2022] [Accepted: 08/11/2022] [Indexed: 11/28/2022] Open
Abstract
Female pattern hair loss (FPHL) is a non-scarring alopecia resulting from the progressive conversion of the terminal (t) scalp hair follicles (HFs) into intermediate/miniaturized (i/m) HFs. Although data supporting nutrient deficiency in FPHL HFs are lacking, therapeutic strategies are often associated with nutritional supplementation. Here, we show by metabolic analysis that selected nutrients important for hair growth such as essential amino acids and vitamins are indeed decreased in affected iHFs compared to tHFs in FPHL scalp skin, confirming nutrient insufficiency. iHFs also displayed a more quiescent metabolic phenotype, as indicated by altered metabolite abundance in freshly collected HFs and release/consumption during organ culture of products/substrates of TCA cycle, aerobic glycolysis, and glutaminolysis. Yet, as assessed by exogenous nutrient supplementation ex vivo, nutrient uptake mechanisms are not impaired in affected FPHL iHFs. Moreover, blood vessel density is not diminished in iHFs versus tHFs, despite differences in tHFs from different FPHL scalp locations or versus healthy scalp or changes in the expression of angiogenesis-associated growth factors. Thus, our data reveal that affected iHFs in FPHL display a relative nutrient insufficiency and dormant metabolism, but are still capable of absorbing nutrients, supporting the potential of nutritional supplementation as an adjunct therapy for FPHL.

Life Sci 2020; 252:117667. [PMID: 32304761 DOI: 10.1016/j.lfs.2020.117667] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2019] [Revised: 03/31/2020] [Accepted: 04/09/2020] [Indexed: 11/18/2022]
Abstract
AIMS Pantothenic acid (PA) has been applied to treat alopecia, but the underlying mechanism is still unclear. Our study aims to explore the underlying mechanism of PA in regulating hair follicle (HF) growth. MAIN METHODS Mink HFs and dermal papilla (DP) cells were isolated and cultured in vitro. HFs and DP cells were treated with 0, 10, 20, 40 μg/ml PA. The effect of PA on HF growth, DP cell proliferation, cell cycle distribution, cell migration, and insulin-like growth factor-1 (IGF-1) and vascular endothelial growth factor (VEGF) expressions in DP cells was measured. Moreover, the effect of PA on inhibitor of DNA binding 3 (ID3)/Notch signaling pathway was analyzed. Subsequently, ID3 was silenced to validate whether ID3/Notch signaling pathway was involved in regulating DP cell proliferation by PA. KEY FINDINGS Both 20 μg/ml and 40 μg/ml PA promoted HF growth, G1/S transition of DP cells and IGF-1 and VEGF expressions in DP cells, while only 20 μg/ml PA promoted cell viability and the migration of DP cells. Thus 20 μg/ml PA was chosen for the following experiments. PA treatment was found to up-regulate ID3 expression but down-regulate Notch receptor 1 (Notch1) and Notch signaling targets expressions. Furthermore, ID3 knockdown reversed PA-induced cell proliferation and inhibition of Notch1 and Notch signaling targets expressions, indicating that PA-induced DP cell proliferation and inhibition of Notch signaling were mediated via up-regulation of ID3. SIGNIFICANCE This study provides an underlying mechanism related to the effect of PA on stimulating DP cell proliferation.

Abstract
The purpose was to evaluate the use of mouse T15 fibroblast cell cultures for the investigation of wound-healing activity. In order to investigate their mechanisms of action, the effects of drugs with wound-healing activities were compared by using morphometric analyses by microscopy after cell staining. A number of parameters were used to evaluate the effects of titrated extracts from Centella asiatica and dexpanthenol (drugs that have been used in medical practice for their wound-healing activities) on cultured mouse T15 fibroblasts. These parameters were: the total number of cells; the number of T15 cells in mitosis; the percentages of fusiform, polygonal, round and vacuole-containing cells; and the number of intracellular collagen granules. The results indicate that these two drugs exhibit wound-healing activities by activating fibroblast cells, and have cytoprotective effects, although their mechanisms of action on mouse T15 fibroblasts were different. On the basis of our findings, mouse T15 fibroblast cell cultures seem to be useful for the pharmacological screening of compounds with wound-healing activity.

Abstract
Approximately 70 years ago, the first topical dexpanthenol-containing formulation (Bepanthen™ Ointment) has been developed. Nowadays, various topical dexpanthenol preparations exist, tailored according to individual requirements. Topical dexpanthenol has emerged as frequently used formulation in the field of dermatology and skin care. Various studies confirmed dexpanthenol's moisturizing and skin barrier enhancing potential. It prevents skin irritation, stimulates skin regeneration and promotes wound healing. Two main directions in the use of topical dexpanthenol-containing formulations have therefore been pursued: as skin moisturizer/skin barrier restorer and as facilitator of wound healing. This 70th anniversary paper reviews studies with topical dexpanthenol in skin conditions where it is most frequently used. Although discovered decades ago, the exact mechanisms of action of dexpanthenol have not been fully elucidated yet. With the adoption of new technologies, new light has been shed on dexpanthenol's mode of action at the molecular level. It appears that dexpanthenol increases the mobility of stratum corneum molecular components which are important for barrier function and modulates the expression of genes important for wound healing. This review will update readers on recent advances in this field.

Abstract
BACKGROUND Vitamins have long been thought to modulate the various stages of wound healing through a variety of proposed mechanisms. Our goal was to investigate relevant studies examining the role of different vitamins in wound healing. METHODS MEDLINE, Cochrane Database of Systematic Reviews, and Google Scholar were searched for basic science and clinical studies examining the role of vitamins as adjuncts in wound healing. RESULTS Mechanisms of action for each of the vitamins are reviewed. It was suggested by many of the studies that the major vitamins A, C, E, D, K, and B have demonstrated utility as adjuncts in wound care in basic science and clinical trials. CONCLUSION There is a vast amount of literature on the effect of vitamins on wound healing at the basic science level. Further understanding and controlled trials will help better understand how to utilize vitamins in wound care. DECLARATION OF INTEREST None.

Abstract
Wound-healing effect of St. John's Wort (Hypericum perforatum L.) extract was evaluated by comparing with dexpanthenol and titrated extract of Centella asiatica (TECA) on cultured chicken embryonic fibroblasts. Chicken embryonic fibroblasts from fertilized eggs were incubated with the plant extract, dexpanthenol and TECA. Using microscopical methods by staining cells, mitotic ability, morphologic changes and collagen production in the cultured fibroblasts were evaluated as parameters to approach its mechanism of action in wound repair. Findings obtained in the present study indicated that Hypericum perforatum extract exhibited a wound-healing activity whose mechanism of action is similar to that of TECA. Wound-healing activity of Hypericum perforatum extract seems to be mainly due to the increase in the stimulation of fibroblast collagen production and the activation of fibroblast cells in polygonal shape, which plays a role in wound repair by closing damaged area. The findings demonstrated the wound-healing activity of Hypericum perforatum, which has previously been based on ethnomedical data.

Abstract
Dry skin (xerosis) is a common symptom of a number of chronic skin diseases, such as atopic dermatitis, but can also be caused by environmental factors, such as cold weather and frequent showering. The condition can cause unsightliness of the skin, discomfort, itching, and can have a negative impact on patients' quality of life. This article will cover recent developments in the understanding of xerosis and its management with emollients. The stratum corneum consists of corneocytes and lipid-enriched intercellular bilayers. These are both produced from keratinocytes in a process called epidermal differentiation. Disturbed epidermal differentiation, resulting in the impairment of stratum corneum intercellular lipid bilayers and natural moisturizing factor, is the root cause of xerosis. The constituent ingredients of emollients should, therefore, address the different factors that contribute to dry skin and, most importantly, attempt to restore epidermal differentiation. The use of lipids, physiological lipids, humectants and antipruritics will help to restore the lipid lamellae, improve skin hydration, skin elasticity and prevent itching. The ideal emollient will include these ingredients plus an agent to support epidermal differentiation. Selecting the correct emollient product and using it regularly are vital factors in the management of xerosis.
