JOURNAL OF ETHNOPHARMACOLOGY 2024; 319:117097. [PMID: 37648176 DOI: 10.1016/j.jep.2023.117097] [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: 06/25/2023] [Revised: 08/19/2023] [Accepted: 08/24/2023] [Indexed: 09/01/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Achyranthes aspera, a widely recognized medicinal plant, is used in various cultures for treating different ailments, including renal dysfunction; however, there is a lack of comprehensive understanding of its protective effects and the underlying signaling networks involved. AIM OF THE STUDY This study aimed to investigate the molecular mechanisms of the action of A. aspera by employing an integrative approach including functional and tissue imaging as well as comprehensive genomics analysis. MATERIALS AND METHODS Cisplatin-induced nephrotoxicity is a well-established animal model for acute kidney injury (AKI). In this study, we investigated the protective effects and underlying mechanisms of the action of A. aspera water-soluble extract (AAW) on a murine model of cisplatin-induced AKI. The evaluation includes measurements of blood urea nitrogen (BUN) and serum creatinine (SCr) levels, histology examination, and transcriptome analysis using RNA sequencing. RESULTS In male ICR mice, oral administration of AAW at doses of 0.5-1.0 g/kg significantly reduced cisplatin-induced nephrotoxicity. This effect included the amelioration of tubular injury, renal fibrosis, and the lowering of BUN and SCr levels. AAW also effectively decreased oxidative markers, such as malondialdehyde (MDA) and nitrotyrosine (NT), along with inflammation markers, including COX-2, iNOS, NLRP3, and pP65NFκB. Moreover, AAW administration induced a dose-dependent increase in the expression of two protective factors, Nrf2 and BcL2, and suppressed apoptosis, as evidenced by reduced levels of truncated caspase 3 (t-Casp3). To explore the underlying molecular mechanisms and signaling networks, next-generation sequencing (NGS) analysis was employed. The results revealed that AAW mitigated apoptosis, necroptosis, and PANoptosis pathways by inhibiting inflammation signaling pathways, such as the TNFα-, NFκB-, NETs-, and leukocyte transendothelial migration pathways. Additionally, AAW was found to enhance protective signaling pathways, including the cGMP/PKG-, cAMP-, AMPK-, and mTOR-dependent activation of autophagy and mitophagy pathways. The primary bioactive compound found in AAW was identified as 20-hydroxyecdysone (0.36%). CONCLUSION Our study demonstrates that AAW reduces cisplatin-induced nephrotoxicity. The protective effects of AAW are attributed to its modulation of multiple molecular signaling networks. Specifically, AAW downregulates genes and signaling pathways associated with oxidative stress and endoplasmic reticulum (ER) stress, inflammation, and PANoptosis. Simultaneously, it upregulates genes and signaling pathways associated with cell survival, including autophagy and mitophagy pathways.

Molecules 2024; 29:339. [PMID: 38257252 PMCID: PMC10820209 DOI: 10.3390/molecules29020339] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2023] [Revised: 01/04/2024] [Accepted: 01/07/2024] [Indexed: 01/24/2024] Open
Abstract
Dianthus superbus L. has been extensively studied for its potential medicinal properties in traditional Chinese medicine and is often consumed as a tea by traditional folk. It has the potential to be exploited in the treatment of inflammation, immunological disorders, and diabetic nephropathy. Based on previous studies, this study continued the separation of another subfraction of Dianthus superbus and established reversed-phase/reversed-phase and reversed-phase/hydrophilic (RPLC) two-dimensional (2D) high-performance liquid chromatography (HPLC) modes, quickly separating two C-glycosylflavones, among which 2″-O-rhamnosyllutonarin was a new compound and isomer with 6‴-O-rhamnosyllutonarin. This is the first study to investigate the effects of 2″-O-rhamnosyllutonarin and 6‴-O-rhamnosyllutonarin on cellular glucose metabolism in vitro. First, molecular docking was used to examine the effects of 2″-O-rhamnosyllutonarin and 6″-O-rhamnosyllutonarin on AKT and AMPK; these two compounds exhibited relatively high activity. Following this, based on the HepG2 cell model of insulin resistance, it was proved that both of the 2″-O-rhamnosyllutonarin and 6‴-O-rhamnosyllutonarin demonstrated substantial efficacy in ameliorating insulin resistance and were found to be non-toxic. Simultaneously, it is expected that the methods developed in this study will provide a basis for future studies concerning the separation and pharmacological effects of C-glycosyl flavonoids.
