[PMID: 39181224 DOI: 10.1016/j.ejphar.2024.176938] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2023] [Revised: 07/26/2024] [Accepted: 08/22/2024] [Indexed: 08/27/2024]
Abstract
There has been significant global interest in respiratory health driven by the coronavirus disease (COVID-19) and severe environmental pollution. This study explored the potential of schisantherin A (SchA), a compound derived from Schisandra chinensis, to protect against acute pneumoconiosis. We assessed the effects of SchA on phorbol 12-myristate 13-acetate (PMA)-stimulated A549 alveolar epithelial cells and SiO2/TiO2-induced pulmonary injury in mice. In A549 cells, SchA significantly decreased pro-inflammatory mediators such as inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), and interleukin (IL)-8 levels. SchA-mediated reduction in inflammatory mediators was associated with the downregulation of PMA-stimulated nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) and mitogen-activated protein kinase (MAPK) signaling activation. In SiO2/TiO2-induced lung-injured mice, SchA administration significantly reduced MUC5AC production in lung tissue. SchA administration significantly downregulated the overexpression of NK-κB and the subsequent production of COX-2, iNOS, and NOD-like receptor pyrin domain-containing protein 3 (NLRP3) inflammasomes. It significantly suppressed expected increases in total cell numbers and pro-inflammatory cytokines, including tumor necrosis factor-alpha (TNF-α) and IL-1β in the bronchoalveolar lavage fluid (BALF) in SiO2/TiO2-stimulated mice. In contrast, the SiO2/TiO2-mediated decrease in IL-10 levels was significantly improved by SchA treatment. These fundamental results can be used to develop potential treatments involving SchA for acute pneumoconiosis.

Int J Biol Macromol 2024; 273:132999. [PMID: 38866280 DOI: 10.1016/j.ijbiomac.2024.132999] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2023] [Revised: 05/14/2024] [Accepted: 06/05/2024] [Indexed: 06/14/2024]
Abstract
This study aimed to confirm macrophage-stimulatory component from Korean meadowsweet (Filipendula glaberrima; FG) and characterize its compositional and structural properties. FG-CWH, prepared via cool-water extraction and ethanol precipitation, induced the highest secretion of NO (6.0-8.0 μM), TNF-α (8.7-9.5 ng/mL), and IL-6 (1.0-5.7 ng/mL) compared to other samples at 0.4-10 μg/mL in RAW 264.7 cells. Analytical results revealed that FG-CWH is a high-molecular-weight component with an average molecular weight of 220 kDa, constituting a polysaccharide-protein mixture. Chemical and enzymatic treatment of FG-CWH indicated its primary composition as arabinogalactan protein (AGP)-rich glycoprotein, with activity likely associated with the chemical and structural characteristics of AGP. FG-CWH treatment resulted in significant and concentration-dependent increases in iNOS (20.0-29.6 folds), TNFα (10.6-18.6 folds) and IL6 (10.9-155.6 folds) gene expression, as well as the secretion of NO (5.3-6.3 μM), TNF-α (35.4-44.3 ng/mL), and IL-6 (4.1-8.4 ng/mL) secretion, even at a reduced concentration range of 125-500 ng/mL, compared to the negative control group. Immunoblotting analysis indicated FG-CWH-induced macrophage stimulation significantly associated with the activation of MAPK (ERK, JNK, and p38) and NF-κB (p65 and IκBα). These findings can serve as valuable groundwork for developing FG-derived AGP as novel functional ingredients to enhance human immunity.

[PMID: 38030023 DOI: 10.1016/j.jep.2023.117510] [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: 10/15/2023] [Revised: 11/20/2023] [Accepted: 11/23/2023] [Indexed: 12/01/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE In China, Capparis spinosa L. fruits (CSF) are often used topically in Uyghur folk medicine in treating rheumatic diseases with remarkable efficacy. However, it has noticed severe skin irritation after a short time application with high dose of CSF, which limited long-term clinical use. To date, there is almost no research related to skin irritation of CSF. AIM OF THE STUDY This study was intended to perform the first systematic assessment of morphological and histological changes in skin after stimulation with CSF. Furthermore, potential irritant components in CSF and related mechanisms were explored by in vitro transdermal techniques, network pharmacology, molecular docking, and experimental validation. MATERIALS AND METHODS Skin changes after single and multiple stimulations with CSF were observed and subjected to skin irritation response scoring, irritation strength assessment, and histopathological analysis. In addition, in vitro transdermal technology, liquid chromatography-mass spectrometry (LC-MS) method, network pharmacology, molecular docking, and experimental validation were used to further exploit underlying skin irritant components and possible mechanisms of action. RESULTS CSF induced significant morphological (erythema and edema) and histological (epidermal thickening and inflammatory infiltration) changes in skin of mice, which were similar to the clinical presentation of irritation contact dermatitis (ICD). The ethyl acetate fraction of CSF (CFEAF) was the main source of CSF-induced skin irritation. Kaempferol, flazin, and gallic acid were potential major irritant compounds. Moreover, CFEAF, kaempferol, flazin, and gallic acid could increase the levels of pro-inflammatory cytokines tumor necrosis factor-alpha (TNF-α), intercellular adhesion molecule-1 (ICAM-1), and interleukin-17A (IL-17A) to promote skin inflammation. The potential mechanism of CSF-induced skin irritation may be activation of the nuclear factor kappa-B (NF-κB) signaling pathway, including phosphorylation of NF-κB p65 (p65) and nuclear factor-kappa B inhibitor alpha (IκBα). CONCLUSION Kaempferol, flazin, and gallic acid are potential skin irritant components from CSF. Altogether, they induce skin irritation responses through promoting the release of the inflammatory factors TNF-α and ICAM-1, as well as activating the NF-κB signaling pathway. In addition, IL-17A may be an important pro-inflammatory factor in skin irritation.

Abstract
Neurogenesis is crucial during the human lifespan for the maintenance of synaptic plasticity and normal function. The impairment of hippocampal neurogenesis in adults may lead to neurodegenerative disease, such as Alzheimer's disease. Miquelianin (quercetin-3-O-β-d-glucuronide, Q3GA) is a constituent of the nuciferine leaf polyphenol extract (NLPE), and it has protective effects against neurodegeneration. In this study, we examined the effect of the NLPE on neurogenesis and the mechanisms underlying Q3GA on neurogenesis. We fed 24-week-old male C57BL/6 mice with 0.1 or 0.25% NLPE for 2 weeks. NLPE treatment increased small spindle-shaped stem cell numbers in the subgranular zone and the number of doublecortin (DCX)- and neuron-specific nuclear protein (NeuN)-expressing neurons. HT22, a hippocampal cell line, treated with Q3GA revealed significant neurite growth and upregulated TrkR and PI3K/Akt levels. The evidence from a model of retinoic acid-induced SH-SY5Y cell differentiation showed that Q3GA or NLPE increases neurite growth significantly. Taken together, the NLPE containing Q3GA to promote neurogenesis involving the upregulation of TrkR and the PI3K/Akt signaling pathway might be potentiated as an alternative strategy for the treatment of neurodegeneration.

Abstract
Genus Filipendula (Rosoideae, Rosaceae) comprises about 15 species and mainly distributed in Northern Hemisphere. The phylogenetic relationships based on the nrITS marker are not consistent with the traditional taxonomic systems of the genus. Here, we first analysed the complete chloroplast (cp) genomes of seven Filipendula species (including two varieties of F. palmate). Our results indicated that the cp genomes of Filipendula species had few changes in size, ranging from 154,205 bp to 154,633 bp and the average of 36.63% GC content. A total of 126 annotated genes had the identical order and orientation, implying that the cp genome structure of Filipendula species was rather conserved. However, the cp genomes of Filipendula species exhibited structural differences, including gene loss, transposition and inversion when compared to those of other genera of Rosoideae. Moreover, SSRs with the different number were observed in the cp genome of each Filipendula species and sequence divergence mainly occurred in noncoding regions, in which four mutational hotspots were identified. In contrast, only two positive selection genes (matK and rps8) were found. Phylogenetic and molecular-dating analysis indicated that Filipendula species were divergent from other genera of Rosoideae at about 82.88 Ma. Additionally, Filipendula species from East Asia were split at about 9.64 Ma into two major clades. These results provide a basis for further studying the infrageneric classification of Filipendula.

Abstract
Introduction: Recently, nanotechnology has emerged as a potential technique for skin generation, which has several treatment advantages, such as decreased drug cytotoxicity and enhanced skin penetration. Boehmeria tricuspis (BT) belongs to the Urticaceae family and is rich in phenolic and flavonoid compounds. In this study, we biosynthesized gold nanoparticles (BT-AuNPs) using BT extract to explore their anti-inflammatory and skin-moisturizing properties in keratinocytes. Methods: Field-emission transmission electron microscopy, energydispersive X-ray spectrometry, dynamic light scattering, and Fourier-transforminfrared spectroscopy were used to examine the synthesized BT-AuNPs. qRT-PCR, western blot, and ELISA were applied for investigating the effect of BT-AuNPs on anti-inflammation and moisturizing activity in HaCaT cells. Results: At concentrations below 200 μg/mL, BT-AuNPs had no cytotoxic effect on keratinocytes. BT-AuNPs dramatically alleviated the expression and secretion of inflammatory chemokines/cytokine, such as IL-6, IL-8, TARC, CTACK, and RANTES in keratinocytes stimulated by tumor necrosis factor-α/interferon-γ (T + I). These anti-inflammatory properties of BT-AuNPs were regulated by inhibiting the NF-κB and MAPKs signaling pathways. Furthermore, BT-AuNPs greatly promoted hyaluronic acid (HA) production by enhancing the expression of hyaluronic acid synthase genes (HAS1, HAS2, and HAS3) and suppressing the expression of hyaluronidase genes (HYAL1 and HYAL2) in HaCaT cells. Discussion: These results suggest that BT-AuNPs can be used as a promising therapeutic alternative for treating skin inflammation. Our findings provide a potential platform for the use of BT-AuNPs as candidates for treating inflammatory skin diseases and promoting skin health.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2023; 114:154794.

Abstract
BACKGROUND Prostate cancer is the second most common cause of cancer death worldwide in men. The development of novel and highly efficient therapeutic strategies is strongly recommended to treat prostate cancer. Cyperaceae are an ecologically and economically important family of plants with several pharmacological effects. However, the biological efficacy of Cyperus exaltatus var. iwasakii (CE) is unknown. PURPOSE This study aimed to investigate the antitumor effect of the ethanol extract of CE against prostate cancer. METHODS In vitro antitumor efficacy of CE was explored by the MTT assay, cell counting assay, FACS analysis, immunoblot, wound-healing migration, invasion assay, zymographic assay, and EMSA in prostate cancer cells, DU145 and LNCaP. For in vivo experiments, xenograft mice were injected with LNCaP cells. Histology (H&E and Ki-67) and biochemical enzyme assay were then performed. The toxicity test was evaluated by an acute toxicity assay. The phytochemical constituents of CE were identified by spectrometric and chromatographic analyses. RESULTS CE exerted a significant antiproliferative effect against prostate cancer cells. CE-induced antiproliferative cells were associated with cell cycle arrest at G0/G1 (cyclin D1/CDK4, cyclin E/CDK2, p21Waf1) in DU145 cells, but G2/M (ATR, CHK1, Cdc2, Cdc25c, p21Waf1, and p53) in LNCaP cells. CE stimulated the phosphorylation of ERK1/2, p38 MAPK, and AKT in DU145 cells, but only p38 MAPK phosphorylation was increased in LNCaP cells. CE treatment suppressed migration and invasion in the two types of prostate cancer cells by inhibiting MMP-9 activity through the regulation of transcription factors, such as AP-1 and NF-κB. In vivo experiments showed a reduction in tumor weight and size following oral CE administration. Histochemistry confirmed that CE inhibited tumor growth in the mouse LNCaP xenograft model. The administration of CE had no adverse effects on body weight, behavioral patterns, blood biochemistry, and histopathology findings of vital organs in mice. Finally, a total of 13 phytochemical constituents were identified and quantified in CE. The most abundant secondary metabolites in CE were astragalin, tricin, and p-coumaric acid. CONCLUSION Our results demonstrated the antitumor efficacy of CE against prostate cancer. These findings suggest that CE might be a potential candidate for prostate cancer prevention or treatment.

Abstract
One promising frontier within the field of Medical Botany is the study of the bioactivity of plant metabolites on human health. Although plant metabolites are metabolic byproducts that commonly regulate ecological interactions and biochemical processes in plant species, such metabolites also elicit profound effects on the cellular processes of human and other mammalian cells. In this regard, due to their potential as therapeutic agents for a variety of human diseases and induction of toxic cellular responses, further research advances are direly needed to fully understand the molecular mechanisms induced by these agents. Herein, we focus our investigation on metabolites from the Cucurbitaceae, Ericaceae, and Rosaceae plant families, for which several plant species are found within the state of Florida in Hillsborough County. Specifically, we compare the molecular mechanisms by which metabolites and/or plant extracts from these plant families modulate the cytoskeleton, protein trafficking, and cell signaling to mediate functional outcomes, as well as a discussion of current gaps in knowledge. Our efforts to lay the molecular groundwork in this broad manner hold promise in supporting future research efforts in pharmacology and drug discovery.

Abstract
Atopic dermatitis (AD), the most common inflammatory skin disorder, is a multifactorial disease characterized by a genetic predisposition, epidermal barrier disruption, a strong T helper (Th) type 2 immune reaction to environmental antigens and an altered cutaneous microbiome. Microbial dysbiosis characterized by the prevalence of Staphylococcus aureus (S. aureus) has been shown to exacerbate AD. In recent years, in vitro models of AD have been developed, but none of them reproduce all of the pathophysiological features. To better mimic AD, we developed reconstructed human epidermis (RHE) exposed to a Th2 pro-inflammatory cytokine cocktail and S. aureus. This model well reproduced some of the vicious loops involved in AD, with alterations at the physical, microbial and immune levels. Our results strongly suggest that S. aureus acquired a higher virulence potential when the epidermis was challenged with inflammatory cytokines, thus later contributing to the chronic inflammatory status. Furthermore, a topical application of a Castanea sativa extract was shown to prevent the apparition of the AD-like phenotype. It increased filaggrin, claudin-1 and loricrin expressions and controlled S. aureus by impairing its biofilm formation, enzymatic activities and inflammatory potential.
