PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2024; 123:155154. [PMID: 37976696 DOI: 10.1016/j.phymed.2023.155154] [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: 06/21/2023] [Revised: 09/25/2023] [Accepted: 10/16/2023] [Indexed: 11/19/2023]
Abstract
OBJECTIVE Alpinia oxyphylla fructus without impurities and shells is called "Yi-Zhi-Ren" (YZR) in Chinese, and traditionally used to alleviate enuresis. The aim of this study was to investigate the effects and underlying mechanisms of YZR in the treatment of overactive bladder (OAB) in spontaneously hypertensive rats (SHR), a vascular disorder-related OAB model. METHODS A 3-week administration of YZR water extract (p.o.) was done, followed by urodynamics to measure bladder parameters. Changes in bladder structure were observed through H&E staining and Masson's staining. An integrated approach involving network pharmacology, transcriptomics and metabolomics was employed to elucidate the potential mechanisms of YZR, and the key proteins involved in the mechanisms were validated by Western blotting. Additionally, network pharmacology was used to predict the relationship between YZR's active components and validated proteins. RESULTS YZR treatment significantly improved the bladder storage parameters, tightened the detrusor layer, reduced inflammatory infiltration, and decreased collagen proportion in the SHR bladder. These results indicated that YZR water extract can alleviate OAB symptoms and improve bladder structure. Integrated analysis suggested that YZR may affect extracellular matrix-receptor interaction and calcium signaling pathway. Western blotting results further confirmed that the reduction in key proteins, such as TGFβ1, p-SMAD3, collagen III, Gq and PLCβ1, involved in collagen synthesis and calcium signaling pathways after YZR treatment. Network pharmacology predicted that sitosterol, chrysin, and nootkatone were potential components responsible for YZR's therapeutic effect on OAB. CONCLUSION YZR's mechanisms of action in treating OAB involved the TGFβ1-SMAD3 signaling pathway-related collagen synthesis and Gq-PLCβ1 calcium signaling pathway, which are associated with detrusor contraction frequency and strength, respectively.

[PMID: 36506568 PMCID: PMC9730235 DOI: 10.3389/fphar.2022.1034515] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2022] [Accepted: 11/10/2022] [Indexed: 11/27/2022] Open
Abstract
Background: Alpiniae Oxyphylla Fructus (AOF) is Traditional Chinese medicine and a dietary supplements for centuries, which posseses cardiotonic, neuroprotective, antioxidant, warming the kidney and nourish the spleen, these biological fuction is related to potential anti-aging properties. However, little is known about their effects on aging. This work aimed to investigate the effects of extracts of AOF on longevity and stress resistance in Caenorhabditis elegans (C. elegans) and the mechanisms that underlie its effects. Methods: Wild-type (WT) strand of C.elegans (N2)worms were cultured in growth medium with or without AOF. First, we examined the effects of AOF on lifespan, reproduction and healthspan assay, stress resistance and oxidative analysis, lipofuscin levels. Second, The levels of ROS and MDA, the antioxidant enzyme activities were examined to explore the underlying mechanism of AOF. Finally, the expression of the longevity-related genes were investigated to further understand the AOF's underlying mechanism. Results: The lifespan of C. elegans was prolonged by 23.44% after treatment with high-dose AOF (100 ug/ml). AOF alleviated aging-related declines in C. elegans health and enhanced resistance to heat shock. Furthermore, AOF decreased reactive oxygen species and malondialdehyde, increased the activities of superoxide dismutase and catalase, and reduced accumulation of fat. AOF upregulated the expression of sod-3, gst-4, daf-16, and skn-1 but downregulated the expression of daf-2 and age-1 and accelerated the translocation of DAF-16 into the nucleus. The extended lifespan induced by AOF was reversed in daf-16(mu86) and skn-1(zu135) mutants, indicating that this gene is involved in AOF-regulated longevity. Conclusion: Our findings demonstrated that AOF extends lifespan and healthspan and enhances stress via boosting the activity of the antioxidant enzyme and controlling the expression of genes associated with insulin/IGF signaling and SKN-1 pathways. As a result, this work suggested AOF as a possible candidate to reduce the signs of aging by activating and inhibiting target genes.

Abstract
Fritillariae Cirrhosae Bulbus (FCB) is a well-known and precious traditional Chinese medicine with a medicinal history spanning thousands of years. In recent years, it has been reported that fungal and mycotoxin contamination influenced the safety and quality of FCB. It is essential to systematically study the fungal community for the early warning of fungal and mycotoxin contamination in this herb. A total of 15 FCB samples were collected from five provinces in China, and the fungal communities in the FCB samples were analyzed via amplifying the internal transcribed spacer 2 region through the Illumina Miseq PE300 platform. Furthermore, we compared the differences in fungal community in five groups based on collection areas. Results showed that Ascomycota (41.58-99.66%) and Mucoromycota (0-57.42%) were dominant at the phylum level. Eurotiomycetes (8.49-63.93%), Eurotiales (8.49-63.53%), and Aspergillaceae (8.49-63.51%) were the most abundant at the class, order, and family levels. Aspergillus (8.49-63.41%), Rhizopus (0-57.42%), Fusarium (0-22.81%), Cladosporium (0.16-9.14%), and Alternaria (0.06-17.95%) were the main genera in FCB samples. A total of 34 fungal taxa were identified at the species level, including five potentially toxigenic fungi namely Penicillium brevicompactum, P. citrinum, P. oxalicum, Trichothecium roseum, and Aspergillus restrictus. The differences in fungal community between the five groups were observed. Our findings provide references for the safe utilization and quality improvement of FCB.
