Hall L, Hart R. Role of corticosteroids in skin physiology and therapeutic potential of an 11β-HSD1 inhibitor: A review. Int J Dermatol 2024; 63:443-454. [PMID: 38146184 DOI: 10.1111/ijd.16967] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/13/2023] [Revised: 11/15/2023] [Accepted: 11/29/2023] [Indexed: 12/27/2023]
Abstract
Skin is a major site of cortisol bioconversion by 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) enzymes which catalyze intracellular inactive cortisone into physiologically active cortisol. 11β-HSD1 is highly expressed in skin, especially in dermal fibroblasts, epidermal keratinocytes, melanocytes, and hair follicles, and plays important roles in regulating keratinocytes, fibroblast proliferation, and has roles in skin aging. Inhibition of 11β-HSD1 may reverse decreased collagen levels observed in extrinsically and intrinsically aged skin. Inhibitors of 11β-HSD1 may also have the potential to reverse decreased collagen observed in skin atrophy induced by glucocorticoid treatment. This systematic review aimed to summarize the current knowledge of roles for 11β-HSD1 inhibitor in skin physiology and potential for future use in medications. Studies have demonstrated that immediately following experimental insult in an animal model, there is increased expression of 11β-HSD1, and that topical application of an 11β-HSD1 inhibitor increases the rate of healing, increases skin collagen content, increases dermal fibroblasts, and increases dermal thickness. Furthermore, in patients with type 2 diabetes mellitus, 11β-HSD1 inhibitors reduce wound diameter after injury. Further development of 11β-HSD1 inhibitors appears to be a promising area for treating aging skin, aiding wound healing, and mitigating effects of systemic glucocorticoid use. Both topically and orally administered 11β-HSD1 inhibitors appear to be viable avenues for future research.

Abstract
The herb Prunella vulgaris has shown significant immune-stimulatory and anti-inflammatory effects in mouse models. Here, the effects of a novel Prunella vulgaris-containing herbal mixture, PV-1, were examined in several mouse models for cancer, including chemically induced models of lung and oral cancers as well as syngraft models for lung cancer and melanoma. PV-1, consisting of extracts from Prunella vulgaris, Polygonum bistorta, Sonchus brachyotus and Dictamnus dasycarpus, exhibited no toxicity in a dose escalation study in A/J mice. PV-1 significantly inhibited mouse lung tumor development induced by the lung carcinogens vinyl carbamate and benzo[a]pyrene. PV-1 also hindered the induction of oral squamous cell carcinomas in C57BL/6 mice caused by 4-nitroquinoline-1-oxide. Flow cytometry analysis showed that PV-1 increased the numbers of CD8+ tumor-infiltrating lymphocytes (TILs) and increased the production of granzyme B, TNF-α, and IFN-γ by CD8+ TILs. PV-1 also suppressed granulocytic myeloid-derived suppressor cell numbers (g-MDSCs) and improved the anti-cancer activity of anti-PD-1 immunotherapy. These results indicate that PV-1 remodels the tumor immune microenvironment by selectively inhibiting g-MDSCs and increasing CD8+ TILs within tumors, resulting in decreased immune suppression and enhanced cancer chemopreventive efficacy.

Review of Medicinal Plants and Active Pharmaceutical Ingredients against Aquatic Pathogenic Viruses. Viruses 2022; 14:v14061281. [PMID: 35746752 PMCID: PMC9230652 DOI: 10.3390/v14061281] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2022] [Accepted: 06/08/2022] [Indexed: 02/04/2023] Open
Abstract
Aquaculture offers a promising source of economic and healthy protein for human consumption, which can improve wellbeing. Viral diseases are the most serious type of diseases affecting aquatic animals and a major obstacle to the development of the aquaculture industry. In the background of antibiotic-free farming, the development and application of antibiotic alternatives has become one of the most important issues in aquaculture. In recent years, many medicinal plants and their active pharmaceutical ingredients have been found to be effective in the treatment and prevention of viral diseases in aquatic animals. Compared with chemical drugs and antibiotics, medicinal plants have fewer side-effects, produce little drug resistance, and exhibit low toxicity to the water environment. Most medicinal plants can effectively improve the growth performance of aquatic animals; thus, they are becoming increasingly valued and widely used in aquaculture. The present review summarizes the promising antiviral activities of medicinal plants and their active pharmaceutical ingredients against aquatic viruses. Furthermore, it also explains their possible mechanisms of action and possible implications in the prevention or treatment of viral diseases in aquaculture. This article could lay the foundation for the future development of harmless drugs for the prevention and control of viral disease outbreaks in aquaculture.

EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:5902293. [PMID: 35399639 PMCID: PMC8989562 DOI: 10.1155/2022/5902293] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/30/2022] [Revised: 02/28/2022] [Accepted: 03/05/2022] [Indexed: 11/24/2022]
Abstract
Dietary nutraceutical compounds have been evidenced as backbone for bone health in recent years. It is reported that medicine food homology (MFH) plants have multiple nutraceutical compounds. Based on our literature research, 20 MFH plants caught our attention because they contain three popular antiosteoporosis compounds simultaneously: quercetin, rutin, and kaempferol. According to traditional Chinese medicine (TCM), their characteristics including natures, flavors, attributive to meridian tropism, and efficacies were listed. The relationships between TCM efficacies, such as “heat clearing,” “tonic,” and “the interior warming,” and antiosteoporosis pharmacological actions such as antioxidant and immune regulation were discussed. The in vivo antiosteoporosis effects of the 20 MFH plants were summarized. The in vitro antiosteoporosis activities and related mechanisms of the 20 plants and quercetin, rutin, kaempferol were detailed. The TGF-β-Smad signaling, fibroblast growth factor, and Wnt/β-catenin signaling on bone formation and the RANKL signaling, NF-κB signaling, and macrophage-colony-stimulating factor on bone resorption were identified. From food point, these 20 MFH plants could be classified as condiment, vegetable, fruit, tea and related products, beverage, etc. Based on the above discussion, these 20 MFH plants could be used as daily food supplements for the prevention and treatment against osteoporosis.

Abstract
Abstract
Background: Prunella vulgaris L., known as self-healing herb, is a widely spread species in the spontaneous flora with beneficial effects on human health, a fact proven in particular by Asian researchers. The aim of this study was to evaluate the antitumor activity and the antibacterial effect on different bacterial strains, including multidrug-resistant ones, depending on the type of solvent used (aqueous, hydroalcoholic), the plant product taken into consideration (spike inflorescence, leaf), its quantity and the concentration of active principles.
Material and method: For screening of antimicrobial susceptibility, both minimum inhibitory concentration and minimum bactericidal concentration were determined on Escherichia coli, Klebsiella pneumoniae, Providencia stuartii, Pseudomonas aeruginosai, and methicillin-resistant Staphylococcus aureus species, including reference strains and hospital strains. Leaves and flower extracts (aqueous and 70% methanolic) were first assessed, and the one with the best antibacterial potential was further tested as a concentrated extract. The antitumor activity was determined on MDA-MB-231 breast adenocarcinoma cells and on a non-tumor cell line, MCF-10A breast epithelial cells by means of Alamar blue technique and Scratch assay.
Results: Inflorescence extracts showed better bacteriostatic effects than leaf extracts on most bacteria, in both aqueous and hydroalcoholic extracts. The concentrated extract of spike inflorescence showed measurable activity with good effects on Gram-positive bacteria, but also on multidrug-resistant Gram-negative ones. The 70% methanolic extract of the species Prunella vulgaris L. (spike inflorescence) demonstrated a concentration-dependent cytotoxic and anti-migratory activity on MDA-MB-231 breast cancer cells, while affecting the non-tumor cell line less.
Conclusions: The results suggest that Prunella vulgaris extracts present antibacterial potential in the complementary treatment of multidrug-resistant infections. The extract from the spike inflorescence of Prunella vulgaris L. produced a dose and time-dependent reduction in cell viability and migration, eliciting a stronger effect on the breast adenocarcinoma cell line.

Synthesis of Kisspeptin-Mimicking Fragments and Investigation of their Skin Anti-Aging Effects. Int J Mol Sci 2020; 21:ijms21228439. [PMID: 33182726 PMCID: PMC7698007 DOI: 10.3390/ijms21228439] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2020] [Revised: 10/30/2020] [Accepted: 11/06/2020] [Indexed: 11/16/2022] Open
Abstract
In recent years, a number of active materials have been developed to provide anti-aging benefits for skin and, among them, peptides have been considered the most promising candidate due to their remarkable and long-lasting anti-wrinkle activity. Recent studies have begun to elucidate the relationship between the secretion of emotion-related hormones and skin aging. Kisspeptin, a neuropeptide encoded by the KISS1 gene, has gained attention in reproductive endocrinology since it stimulates the reproductive axis in the hypothalamus; however, the effects of Kisspeptin on skin have not been studied yet. In this study, we synthesized Kisspeptin-10 and Kisspeptin-E, which are biologically active fragments, to mimic the action of Kisspeptin. Next, we demonstrated the anti-aging effects of the Kisspeptin-mimicking fragments using UV-induced skin aging models, such as UV-induced human dermal fibroblasts (Hs68) and human skin explants. Kisspeptin-E suppressed UV-induced 11 beta-hydroxysteroid dehydrogenase type 1 (11β-HSD1) stimulation leading to a regulation of skin aging related genes, including type I procollagen, matrix metalloproteinases-1 (MMP-1), interleukin-6 (IL-6), and IL-8, and rescued the skin integrity. Taken together, these results suggest that Kisspeptin-E could be useful to improve UV-induced skin aging by modulating expression of stress related genes, such as 11β-HSD1.

Front Endocrinol (Lausanne) 2020; 11:579648.

Abstract
Prunella vulgaris (PV), a perennial herb, has been used to treat thyroid diseases in China for over 2,000 years. In particular, its therapeutic effect has been described for Hashimoto's thyroiditis, including reducing titers autoantibodies against thyroid peroxidase and thyroglobulin of and T helper 17 (Th17) cells. However, the underlying mechanism for how PV exerts such effects has not been investigated. We examined the effects of PV on innate immune activation, which is thought to be one of the triggers for the development of autoimmune diseases, including Hashimoto's thyroiditis. In cultured thyrocytes, PV reduced mRNA levels of inflammatory cytokines that were originally induced as a result of innate immune activation initiated by transfection of double-stranded DNA (dsDNA) or dsRNA. PV suppressed activation of nuclear factor κB (NF-κB) and interferon regulatory factor 3 (IRF3), and suppressed corresponding promoter activation, which were initially activated by dsDNA or dsRNA. PV also suppressed the mRNA levels of molecules responsible for antigen processing and presentation, and PV protected thyrocytes from apoptosis induced by dsDNA and dsRNA. Additionally, PV suppressed the expression of genes involved in iodide uptake and oxidation. Taken together, these results suggest that PV exerts its protective effect on thyrocytes by suppressing both innate and adaptive immune responses and cell death. PV may also protect cells from iodide-associated oxidative injury. This report is among the first to identify the mechanisms to explain PV's beneficial effects in Hashimoto's thyroiditis.
