JOURNAL OF ETHNOPHARMACOLOGY 2024; 323:117673. [PMID: 38158096 DOI: 10.1016/j.jep.2023.117673] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/20/2023] [Revised: 12/14/2023] [Accepted: 12/26/2023] [Indexed: 01/03/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Tribuloside, a natural flavonoid extracted from Chinese medicine Tribulus terrestris L., has shown potent efficacy in treating various diseases. In China, the fruits of Tribulus terrestris L. have long been utilized for relieving headache, dizziness, itchiness, and vitiligo. Water-based extract derived from Tribulus terrestris L. can enhance melanogenesis in mouse hair follicle melanocytes by elevating the expression of α-melanocyte stimulating hormone (α-MSH) and melanocortin-1 recepter (MC-1R). Nevertheless, there is a lack of information regarding the impact of tribuloside on pigmentation in both laboratory settings and living organisms. AIM OF THE STUDY The present research aimed to examine the impact of tribuloside on pigmentation, and delve into the underlying mechanism. MATERIALS AND METHODS Following the administration of tribuloside in human epidermal melanocytes (HEMCs), we utilized microplate reader, Masson-Fontana ammoniacal silver stain, transmission electron microscopy (TEM) and scanning electron microscopy (SEM) to measure melanin contents, dendrite lengths, melanosome counts; L-DOPA oxidation assay to indicate tyrosinase activity, Western blotting to evaluate the expression of melanogenic and associated phosphodiesterase (PDE)/cyclic adenosine monophosphate (cAMP)/cyclic-AMP dependent protein kinase A (PKA) pathway proteins. A PDE-Glo assay to verify the inhibitory effect of tribuloside on PDE was also conducted. Additionally, we examined the impact of tribuloside on the pigmentation in both zebrafish model and human skin samples. RESULTS Tribuloside had a notable impact on the production of melanin in melanocytes, zebrafish, and human skin samples. These functions might be attributed to the inhibitory effect of tribuloside on PDE, which could increase the intracellular level of cAMP to stimulate the phosphorylation of cAMP-response element binding (CREB). Once activated, it induced microphthalmia-associated transcription factor (MITF) expression and increased the expression of tyrosinase, Rab27a and cell division cycle protein 42 (Cdc42), ultimately facilitating melanogenesis, melanocyte dendricity, and melanin transport. CONCLUSION Tribuloside acts on the PDE/cAMP/PKA pathway to enhance melanogenesis, melanocyte dendricity, and melanosome transport; meanwhile, tribuloside does not have any toxic effects on cells and may be introduced into clinical prescriptions to promote pigmentation.

Ho TY, Lo HY, Lu GL, Liao PY, Hsiang CY. Analysis of target organs of Houttuynia cordata: A study on the anti-inflammatory effect of upper respiratory system. JOURNAL OF ETHNOPHARMACOLOGY 2023:116687. [PMID: 37244408 DOI: 10.1016/j.jep.2023.116687] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/06/2023] [Revised: 05/23/2023] [Accepted: 05/24/2023] [Indexed: 05/29/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Houttuynia cordata Thunb. (HC) is a traditional anti-pyretic herb that is classified as the lung meridian in traditional Chinese medicine. However, no articles have explored the main organs responsible for the anti-inflammatory activities of HC. AIM OF THE STUDY The aim of the study was to investigate the meridian tropism theory of HC in lipopolysaccharide (LPS)-induced pyretic mice, as well as to identify the underlying mechanisms. MATERIALS AND METHODS Transgenic mice carrying the luciferase gene driven by nuclear factor-κB (NF-κB) were intraperitoneally injected with LPS and orally administered standardized concentrated HC aqueous extract. The phytochemicals present in the HC extract were analyzed using high-performance liquid chromatography. In vivo and ex vivo luminescent imaging from transgenic mice was used to investigate the meridian tropism theory and anti-inflammatory effects of HC. Microarray analysis of gene expression patterns was used to elucidate the therapeutic mechanisms of HC. RESULTS HC extract was found to contain phenolic acids, such as protocatechuic acid (4.52%) and chlorogenic acid (8.12%), as well as flavonoids like rutin (2.05%) and quercitrin (7.73%). The bioluminescent intensities induced by LPS in the heart, liver, respiratory system, and kidney were significantly suppressed by HC, while the maximal decrease (about 90% reduction) of induced luminescent intensity was observed in the upper respiratory tract. These data suggested that upper respiratory system might be the target for HC anti-inflammatory abilities. HC affected the processes involved in innate immunity, such as chemokine-mediated signaling pathway, inflammatory response, chemotaxis, neutrophil chemotaxis, and cellular response to interleukin-1 (IL-1). Moreover, HC significantly reduced the proportions of p65-stained cells and the amount of IL-1β in trachea tissues. CONCLUSION Bioluminescent imaging coupled with gene expression profile was used to demonstrate the organ selectivity, anti-inflammatory effects, and therapeutic mechanisms of HC. Our data demonstrated for the first time that HC displayed lung meridian-guiding effects and exhibited great anti-inflammatory potential in the upper respiratory tract. The NF-κB and IL-1β pathways were associated with the anti-inflammatory mechanism of HC against LPS-provoked airway inflammation. Moreover, chlorogenic acid and quercitrin might be involved in the anti-inflammatory properties of HC.

Terrestrosin D ameliorates skin lesions in an imiquimod-induced psoriasis-like murine model by inhibiting the interaction between Substance P and Dendritic cells. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2022; 95:153864. [PMID: 34923236 DOI: 10.1016/j.phymed.2021.153864] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/25/2021] [Revised: 10/13/2021] [Accepted: 10/22/2021] [Indexed: 06/14/2023]
Abstract
BACKGROUND Psoriasis is a psychosomatic immune skin disease with psychological factors contributing to the disease. Substance P (SP) is highly expressed in the psoriatic lesions of patients and is involved in pathological disease progression. Tribulus terrestris L. has been used as a Chinese herbal medicine for disease prevention for thousands of years. Terrestrosin D (TED) has been identified as the effective monomeric component of Tribulus terrestris L.. PURPOSE We investigated whether TED could reverse imiquimod-induced psoriatic lesions, and then, investigated its potential mechanism of action both in vivo and in vitro. METHODS 5% imiquimod cream was applied onto the backs of mice for 6 days to induce psoriasis-like skin lesions. The psoriatic area and severity index (PASI) was then used for scoring disease severity. Pathological changes and Ki-67 expression levels in skin lesions were measured using hematoxylin and eosin (H&E) and immunofluorescence staining after TED administration. The in vivo and in vitro expression levels of inflammatory cytokines, the ratio of DCs, and SP were measured using ProcartaPlex Mouse Cytokine panels, flow cytometry, and western blotting. Behavioral assessments were determined using the open field and elevated plus-maze (EPM) test. RESULTS TED decreased PASI scores, epidermal thickness, Ki-67 expression levels, the ratio of DCs in the spleen, and secretion of IL-12p70, IL-18, and TNF-α in imiquimod-induced psoriasis-like murine models. Furthermore, TED increased IL-10 secretion levels, improved behavior, and down-regulated the expression levels of SP. Additionally, TED inhibited the in vitro maturation and activation of SP-induced CD11c+ DCs and the release of IL-12p70 and IL-23. CONCLUSION TED reduced DCs maturation, down-regulated the expression levels of inflammatory factors, and improved skin lesions and behavior of psoriasis-like murine models by inhibiting the interaction between Substance P and Dendritic cells.

Ethosomes-based gel formulation of karanjin for treatment of acne vulgaris: in vitro investigations and preclinical assessment. 3 Biotech 2021; 11:456. [PMID: 34631355 DOI: 10.1007/s13205-021-02978-3] [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: 12/20/2020] [Accepted: 08/27/2021] [Indexed: 01/09/2023] Open
Abstract
The aim of the present study was to develop and characterize karanjin-loaded ethosomes-based gel formulation for enhanced topical delivery and effective therapy of skin acne. Karanjin-loaded ethosomes (K-ETH) presented a nanometric size of 140.87 ± 2.35 nm, entrapment of 71.41 ± 2.74% and enhanced permeation with 1.9 times increase in the flux and 2.4 times higher skin deposition compared to the hydro-ethanolic solution of karanjin. The DSC analysis confirmed successful entrapment of the karanjin within the ethosomes. The developed ethosomes were incorporated in the carbopol gel for adequate application on the skin surface. The ethosomal gel (K-EGF) also exhibited greater penetration in the rat skin as revealed by CLSM. The optimized K-EGF formulation was non-irritant to the skin as evident by Draize score test and histopathological examination. The highest zone of inhibition, 30.0 ± 1.52 mm and 36.22 ± 0.57 mm was produced by the K-EGF against Propionibacterium acnes and Staphylococcus epidermidis, respectively, indicating substantial antibacterial properties of the K-EGF. DPPH assay indicated its potent antioxidant effects. Substantial anti-inflammatory effects in the carrageenan-induced edema in the rat paw were evident with inhibition of rat paw edema by 66.66% and 70.37% upon application of K-EGF and standard anti-inflammatory agent, respectively. Anti-acne effects were also evident with K-EGF treatment with significant decrease in number and size of sebaceous gland units in dermis. Overall, the above findings vouch for a therapeutic opportunity to improve topical delivery of karanjin in acne treatment employing ethosomal gels as the promising carrier system.

Abstract
Houttuynia cordata Thunb (H. cordata; Saururaceae) is widely distributed in Asian regions. It plays an important role in traditional health care and disease treatment, as its aboveground stems and leaves have a long medicinal history in China and are used in the treatment of pneumonia and lung abscess. In clinical treatment, it can usually be combined with other drugs to treat dysentery, cold, fever, and mumps; additionally, H. cordata is an edible plant. This review summarizes detailed information on the phytochemistry and pharmacological effects of H. cordata. By searching the keywords “H. cordata and lung”, “H. cordata and heart”, “H. cordata and liver”, and “H. cordata and inflammation” in PubMed, Web of Science and ScienceDirect, we screened out articles with high correlation in the past ten years, sorted out the research contents, disease models and research methods of the articles, and provided a new perspective on the therapeutic effects of H. cordata. A variety of its chemical constituents are characteristic of medicinal plants, the chemical constituents were isolated from H. cordata, including volatile oils, alkaloids, flavonoids, and phenolic acids. Flavonoids and volatile oils are the main active components. In pharmacological studies, H. cordata showed organ protective activity, such as reducing the release of inflammatory factors to alleviate lung injury. Moreover, H. cordata regulates immunity, enhances the immune barriers of the vagina, oral cavity, and intestinal tract, and combined with the antibacterial and antiviral activity of its extract, effectively reduces pathogen infection. Furthermore, experiments in vivo and in vitro showed significant anti-inflammatory activity, and its chemical derivatives exert potential therapeutic activity against rheumatoid arthritis. Antitumour action is also an important pharmacological activity of H. cordata, and studies have shown that H. cordata has a notable effect on lung tumour, liver tumour, colon tumour, and breast tumour. This review categorizes the biological activities of H. cordata according to modern research papers, and provides insights into disease prevention and treatment of H. cordata.

Abstract
BACKGROUND Fat grafting is a popular operative approach for rejuvenation. Some patients requiring facial fat grafting also have acne. Fat grafting may improve acne in some patients. OBJECTIVES The aim of this study was to assess whether fat grafting can improve acne and to analyze the mechanism of action by which such improvement occurs. METHODS Preoperative and postoperative digital photographs were examined retrospectively in 229 patients who underwent fat grafting to compare the numbers of inflammatory acne lesions. In addition, 18 patients with acne who were treated by injection of subdermal stromal vascular fraction gel (SVF-gel) were examined prospectively. The numbers of inflammatory acne lesions before and after treatment were measured, and changes in the levels of CD4+ T-cell infiltration were determined from immunohistochemical staining. RESULTS Of the 229 retrospectively evaluated patients who underwent fat grafting, 22 had acne and had complete follow-up data; in these patients, the numbers of acne lesions were significantly lower after than before treatment. The 18 patients who received subdermal SVF-gel injection showed evident improvements in inflammatory lesions after more than 1 year of follow-up. CD4+ T-cell infiltration was significantly decreased at week 4. CONCLUSIONS Facial fat grafting can improve inflammatory acne lesions, perhaps because adipose-derived stem cells, which are plentiful in SVF-gel, reduce CD4+ T-cell-mediated inflammation responses.

Abstract
Simple Summary This study explored the chemopreventive effects of Houttuynia cordata Thunb. (HCT) extracts against prostate carcinogenesis in both androgen-sensitive prostate cancer and castration-resistant prostate cancer (CRPC) using the Transgenic Rat for Adenocarcinoma of Prostate (TRAP) model, CRPC xenograft mice, and prostate cancer cell lines. HCT suppressed cell proliferation and stimulated apoptosis via inactivation of AKT/ERK/MAPK in both androgen-sensitive prostate cancer and CRPC cell lines. HCT also inhibited cell migration and EMT phenotypes through the STAT3/Snail/Twist pathway. One of the active compounds of HCT was identified as rutin. Consistent with in vitro study, the incidence of adenocarcinoma in the TRAP model and CRPC tumor growth in the xenograft model were suppressed by induction of apoptosis and inactivation of AKT/ERK/MAPK by HCT intake. Our data demonstrated that HCT attenuated androgen-sensitive prostate cancer and CRPC by mechanisms that may involve inhibition of cell growth and caspase-dependent apoptosis pathways. Abstract Houttuynia cordata Thunb. (HCT) is a well-known Asian medicinal plant with biological activities used in the treatment of many diseases including cancer. This study investigated the effects of HCT extract and its ethyl acetate fraction (EA) on prostate carcinogenesis and castration-resistant prostate cancer (CRPC). HCT and EA induced apoptosis in androgen-sensitive prostate cancer cells (LNCaP) and CRPC cells (PCai1) through activation of caspases, down-regulation of androgen receptor, and inactivation of AKT/ERK/MAPK signaling. Rutin was found to be a major component in HCT (44.00 ± 5.61 mg/g) and EA (81.34 ± 5.21 mg/g) in a previous study. Rutin had similar effects to HCT/EA on LNCaP cells and was considered to be one of the active compounds. Moreover, HCT/EA inhibited cell migration and epithelial-mesenchymal transition phenotypes via STAT3/Snail/Twist pathways in LNCaP cells. The consumption of 1% HCT-mixed diet significantly decreased the incidence of adenocarcinoma in the lateral prostate lobe of the Transgenic rat for adenocarcinoma of prostate model. Similarly, tumor growth of PCai1 xenografts was significantly suppressed by 1% HCT treatment. HCT also induced caspase-dependent apoptosis via AKT inactivation in both in vivo models. Together, the results of in vitro and in vivo studies indicate that HCT has inhibitory effects against prostate carcinogenesis and CRPC. This plant therefore should receive more attention as a source for the future development of non-toxic chemopreventive agents against various cancers.

Chang JE, Choi MS. A Molecular Perspective on the Potential Benefits of Metformin for the Treatment of Inflammatory Skin Disorders. Int J Mol Sci 2020; 21:ijms21238960. [PMID: 33255783 PMCID: PMC7728327 DOI: 10.3390/ijms21238960] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2020] [Revised: 11/21/2020] [Accepted: 11/23/2020] [Indexed: 02/07/2023] Open
Abstract
Due to its anti-hyperglycemic effect, metformin is the first-line medication for the treatment of type 2 diabetes, particularly in people who are obese. However, metformin is a drug with a very wide range of pharmacological properties and reports of its therapeutic effect on diseases including inflammation and cancer are increasing. Numerous research groups have reported that metformin has beneficial effects on a variety of inflammatory skin disorders including psoriasis, acanthosis nigricans, acne, hidradenitis suppurativa, and allergic contact dermatitis. According to these reports, in addition to the well-known action of metformin, that is, its anti-hyperglycemic effect, NF-kB inhibition and the resulting alteration to the cytokine network may be the potential targets of metformin. Its anti-hyperandrogenism effect has also been confirmed as the major action of metformin in some inflammatory skin diseases. Moreover, novel regulatory mechanisms, including autophagy and antioxidant processes, have been suggested as promising mechanisms of action for metformin in inflammatory skin disorders.
