Evaluating the therapeutic potential of moxibustion on polycystic ovary syndrome: a rat model study on gut microbiota and metabolite interaction. Front Cell Infect Microbiol 2024; 14:1328741. [PMID: 38665877 PMCID: PMC11043641 DOI: 10.3389/fcimb.2024.1328741] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2023] [Accepted: 03/13/2024] [Indexed: 04/28/2024] Open
Abstract
Polycystic ovary syndrome (PCOS) is a common systemic disorder related to endocrine disorders, affecting the fertility of women of childbearing age. It is associated with glucose and lipid metabolism disorders, altered gut microbiota, and insulin resistance. Modern treatments like pioglitazone, metformin, and spironolactone target specific symptoms of PCOS, while in Chinese medicine, moxibustion is a common treatment. This study explores moxibustion's impact on PCOS by establishing a dehydroepiandrosterone (DHEA)-induced PCOS rat model. Thirty-six specific pathogen-free female Sprague-Dawley rats were divided into four groups: a normal control group (CTRL), a PCOS model group (PCOS), a moxibustion treatment group (MBT), and a metformin treatment group (MET). The MBT rats received moxibustion, and the MET rats underwent metformin gavage for two weeks. We evaluated ovarian tissue changes, serum testosterone, fasting blood glucose (FBG), and fasting insulin levels. Additionally, we calculated the insulin sensitivity index (ISI) and the homeostasis model assessment of insulin resistance index (HOMA-IR). We used 16S rDNA sequencing for assessing the gut microbiota, 1H NMR spectroscopy for evaluating metabolic changes, and Spearman correlation analysis for investigating the associations between metabolites and gut microbiota composition. The results indicate that moxibustion therapy significantly ameliorated ovarian dysfunction and insulin resistance in DHEA-induced PCOS rats. We observed marked differences in the composition of gut microbiota and the spectrum of fecal metabolic products between CTRL and PCOS rats. Intriguingly, following moxibustion intervention, these differences were largely diminished, demonstrating the regulatory effect of moxibustion on gut microbiota. Specifically, moxibustion altered the gut microbiota by increasing the abundance of UCG-005 and Turicibacter, as well as decreasing the abundance of Desulfovibrio. Concurrently, we also noted that moxibustion promoted an increase in levels of short-chain fatty acids (including acetate, propionate, and butyrate) associated with the gut microbiota of PCOS rats, further emphasizing its positive impact on gut microbes. Additionally, moxibustion also exhibited effects in lowering FBG, testosterone, and fasting insulin levels, which are key biochemical indicators associated with PCOS and insulin resistance. Therefore, these findings suggest that moxibustion could alleviate DHEA-induced PCOS by regulating metabolic levels, restoring balance in gut microbiota, and modulating interactions between gut microbiota and host metabolites.

Sodium acetate ameliorates doxorubicin-induced cardiac injury via upregulation of Nrf2/HO-1 signaling and downregulation of NFkB-mediated apoptotic signaling in Wistar rats. NAUNYN-SCHMIEDEBERG'S ARCHIVES OF PHARMACOLOGY 2024; 397:423-435. [PMID: 37458777 DOI: 10.1007/s00210-023-02620-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/24/2023] [Accepted: 07/10/2023] [Indexed: 01/07/2024]
Abstract
Despite the effectiveness of doxorubicin (DOX) in the management of a wide range of cancers, a major challenge is its cardio-toxic effect. Oxidative stress, inflammation, and apoptosis are major pathways for the cardiotoxic effect of DOX. On the other hand, acetate reportedly exerts antioxidant, anti-inflammatory, and anti-apoptotic activities. This particular research assessed the impact of acetate on cardiotoxicity induced by DOX. Mechanistically, acetate dramatically inhibited DOX-induced upregulation of xanthine oxidase and uric acid pathway as well as downregulation of Nrf2/HO-1 signaling and its upstream proteins (reduced glutathione peroxidase, superoxide dismutase, glutathione-S-transferase, glutathione, and catalase, glutathione reductase). In addition, acetate markedly attenuated DOX-driven rise inTNF-α, NFkB IL-6 and IL-1β expression, and myeloperoxidase activity. Furthermore, acetate significantly ameliorated DOX-led suppression of Bcl-2 and Ca2+-ATPase activity and upregulation of Bax, caspase 3, and caspase 9 actions. Improved body weight, heart structural integrity, and cardiac function as depicted by cardiac injury markers convoyed these cascades of events. Summarily, the present study demonstrated that acetate protects against DOX-induced cardiotoxicity by upregulating Nrf2/HO-1 signaling and downregulating NFkB-mediated activation of Bax/Bcl-2 and caspase signaling.

Adeyemi DH, Hamed MA, Oluwole DT, Omole AI, Akhigbe RE. Acetate attenuates cyclophosphamide-induced cardiac injury via inhibition of NF-kB signaling and suppression of caspase 3-dependent apoptosis in Wistar rats. Biomed Pharmacother 2024; 170:116019. [PMID: 38128178 DOI: 10.1016/j.biopha.2023.116019] [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: 10/16/2023] [Revised: 12/08/2023] [Accepted: 12/14/2023] [Indexed: 12/23/2023] Open
Abstract
AIM The goal of the current study was to examine the potential therapeutic effects of sodium acetate on cardiac toxicities caused by cyclophosphamide in Wistar rats. The possible involvement of NF-kB/caspase 3 signaling was also explored. MAIN METHODS Thirty-two male Wistar rats were divided into four groups at random. (n = 8). The control animals received 0.5 mL of distilled water orally for 14 days, the acetate-treated group received 200 mg/kg/day of sodium acetate orally for 14 consecutive days, and cyclophosphamide-treated rats received 150 mg/kg /day of cyclophosphamide i.p. on day 8, while cyclophosphamide + acetate group received sodium acetate and cyclophosphamide as earlier stated. KEY FINDINGS Results showed that cyclophosphamide-induced cardiotoxicity, which manifested as a marked drop in body and cardiac weights as well as cardiac weight/tibial length, increased levels of troponin, C-reactive protein, lactate, and creatinine kinase, and lactate dehydrogenase activities in the plasma and cardiac tissue. Histopathological examination also revealed toxic cardiac histopathological changes. These alterations were associated with a significant increase in xanthine oxidase and myeloperoxidase activities, uric acid, malondialdehyde, TNF-α, IL-1β, NFkB, DNA fragmentation, and caspase 3 and caspase 9 activities in addition to a marked decline in Nrf2 and GSH levels, and SOD and catalase activities in the cardiac tissue. Acetate co-administration significantly attenuated cyclophosphamide cardiotoxicity by its antioxidant effect, preventing NFkB activation and caspase 9/caspase 3 signalings. SIGNIFICANCE This study shows that acetate co-administration may have cardio-protective effects against cyclophosphamide-induced cardiotoxicity by inhibiting NF-kB signaling and suppressing caspase-3-dependent apoptosis.
