Antibiotic-induced gut microbiota disruption promotes vascular calcification by reducing short-chain fatty acid acetate. Mol Med 2024; 30:130. [PMID: 39182021 PMCID: PMC11344439 DOI: 10.1186/s10020-024-00900-0] [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: 05/08/2024] [Accepted: 08/14/2024] [Indexed: 08/27/2024] Open
Abstract
BACKGROUND Vascular calcification is a common vascular lesion associated with high morbidity and mortality from cardiovascular events. Antibiotics can disrupt the gut microbiota (GM) and have been shown to exacerbate or attenuate several human diseases. However, whether antibiotic-induced GM disruption affects vascular calcification remains unclear. METHODS Antibiotic cocktail (ABX) treatment was utilized to test the potential effects of antibiotics on vascular calcification. The effects of antibiotics on GM and serum short-chain fatty acids (SCFAs) in vascular calcification mice were analyzed using 16 S rRNA gene sequencing and targeted metabolomics, respectively. Further, the effects of acetate, propionate and butyrate on vascular calcification were evaluated. Finally, the potential mechanism by which acetate inhibits osteogenic transformation of VSMCs was explored by proteomics. RESULTS ABX and vancomycin exacerbated vascular calcification. 16 S rRNA gene sequencing and targeted metabolomics analyses showed that ABX and vancomycin treatments resulted in decreased abundance of Bacteroidetes in the fecal microbiota of the mice and decreased serum levels of SCFAs. In addition, supplementation with acetate was found to reduce calcium salt deposition in the aorta of mice and inhibit osteogenic transformation in VSMCs. Finally, using proteomics, we found that the inhibition of osteogenic transformation of VSMCs by acetate may be related to glutathione metabolism and ubiquitin-mediated proteolysis. After adding the glutathione inhibitor Buthionine sulfoximine (BSO) and the ubiquitination inhibitor MG132, we found that the inhibitory effect of acetate on VSMC osteogenic differentiation was weakened by the intervention of BSO, but MG132 had no effect. CONCLUSION ABX exacerbates vascular calcification, possibly by depleting the abundance of Bacteroidetes and SCFAs in the intestine. Supplementation with acetate has the potential to alleviate vascular calcification, which may be an important target for future treatment of vascular calcification.

Abstract
Introduction Vascular calcification is a major cause of cardiovascular accidents in patients with type 2 diabetes mellitus. This study aimed to investigate the impact of carbohydrates on gut microbiota and aortic calcification in diabetic ApoE-/- mice. Methods The diabetic ApoE-/- mice were randomly divided into 4 groups: ketogenic diet group, low carbohydrate diet group, medium carbohydrate diet group, and high carbohydrate diet group. The mice were fed continuously for 6 months, with blood glucose, blood ketone and body weight monitored monthly. Lipid metabolism indicators and inflammatory factors were detected using ELISA. The intestinal barrier, atherosclerotic lesion areas, and vascular calcifications were analyzed based on their morphology. Gut microbiota was analyzed using 16S rRNA genes. Results We found that ketogenic diet played some roles improving glucose, lipid metabolism, and inflammation. Ketogenic diet could improve the intestinal barrier to some extent and increase intestinal bacteria. Compared to the other three groups, the relative abundance of genus Allobaculum, species Blautia producta and Clostridium Ramosum in the ketogenic diet group was significantly increased (P <0.05), which has protective effects in diabetic ApoE-/- mice. Conclusion Ketogenic diet could delay the onset of aortic atherosclerosis, aortic calcification and improve intestinal barrier function in diabetic ApoE-/- mice.

Abstract
Coronary artery calcification (CAC) is mainly associated with coronary atherosclerosis, which is an indicator of coronary artery disease (CAD). CAC refers to the accumulation of calcium phosphate deposits, classified as micro- or macrocalcifications, that lead to the hardening and narrowing of the coronary arteries. CAC is a strong predictor of future cardiovascular events, such as myocardial infarction and sudden death. Our narrative review focuses on the pathophysiology of CAC, exploring its link to plaque vulnerability, genetic factors, and how race and sex can affect the condition. We also examined the connection between the gut microbiome and CAC, and the impact of genetic variants on the cellular processes involved in vascular calcification and atherogenesis. We aimed to thoroughly analyze the existing literature to improve our understanding of CAC and its potential clinical and therapeutic implications.

Front Nutr 2023; 10:1267607. [PMID: 38075227 PMCID: PMC10704926 DOI: 10.3389/fnut.2023.1267607] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2023] [Accepted: 10/10/2023] [Indexed: 07/02/2024] Open
Abstract
OBJECT To explore the potential association between dietary live microbe intake and abdominal aortic calcification (AAC). METHODS We conducted a cross-section study based on the National Health and Nutrition Examination Survey (NHANES). We categorized the participants into three groups (low, medium, and high dietary intake of live microbes) according to Sanders's dietary live microbe classification system and participants' 24-h dietary recall data. AAC was quantified by using dual-energy X-ray absorptiometry (DXA) and diagnosed by using the Kauppila AAC-24 score system. The analyses utilized weighted logistic regression and weighted linear regression. RESULTS A total of 2,586 participants were included. After the full adjustment for covariates, compared to participants with a low dietary live microbe intake, participants with a high dietary live microbe intake had a significantly lower risk of severe AAC (OR: 0.39, 95% CI: 0.22, 0.68, p = 0.003), and the AAC score was also significantly decreased (β:-0.53, 95% CI: -0.83, -0.23, p = 0.002). CONCLUSION In this study, more dietary live microbial intake was associated with lower AAC scores and a lower risk of severe AAC. However, more research is needed to verify this.
