Nutr Metab Cardiovasc Dis 2024; 34:230-234. [PMID: 38000989 DOI: 10.1016/j.numecd.2023.10.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/11/2023] [Revised: 08/27/2023] [Accepted: 10/04/2023] [Indexed: 11/26/2023]
Abstract
BACKGROUND AND AIMS Leukocyte telomere length (LTL) has been correlated with uric acid levels, although results are inconsistent, and prospective studies are lacking. In this longitudinal, prospective cohort study, we aimed to assess whether a shorter LTL predicts the risk of hyperuricemia. METHODS AND RESULTS We conducted a longitudinal study in a Chinese cohort of 599 participants. Of these, 266 participants completed a 5.9-year follow-up from June 2014 to December 2021. LTL was assessed at baseline using real-time polymerase chain reaction. Hyperuricemia was defined as serum uric acid ≥420 mmol/L according to Chinese guidelines for diagnosis and treatment of hyperuricemia and gout. Participants who had developed hyperuricemia during follow-up (n = 17) had shorter LTL at baseline. Baseline LTL was independently associated with the development of hyperuricemia at follow-up after adjusting for conventional hyperuricemia risk factors (odds ratio [OR] 2.347 [95% confidence interval [CI] 1.123, 4.906]; P = 0.023). After grouping according to LTL tertiles, the incidence of hyperuricemia was 18.334-fold higher for the first than for the third tertile (OR 18.334 [95%CI 1.786, 191.272]; P = 0.014, P for trend = 0.050). CONCLUSION Our findings in a prospective cohort suggest that LTL could predict hyperuricemia risk, which might inform the timely prevention and treatment of hyperuricemia.

Hyperuricemia remodels the serum proteome toward a higher inflammatory state. iScience 2023; 26:107909. [PMID: 37810213 PMCID: PMC10550725 DOI: 10.1016/j.isci.2023.107909] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2023] [Revised: 08/01/2023] [Accepted: 09/08/2023] [Indexed: 10/10/2023] Open
Abstract
Gout is an autoinflammatory disease triggered by a complex innate immune response to MSU crystals and inflammatory triggers. While hyperuricemia is an obligatory risk factor for the development of gout, the majority of individuals with hyperuricemia never develop gout but have an increased risk of developing cardiometabolic disorders. Current management of gout aims at MSU crystal dissolution by lowering serum urate. We apply a targeted proteomic analysis, using Olink inflammation panel, to a large group of individuals with gout, asymptomatic hyperuricemia, and normouricemic controls, and we show a urate-driven inflammatory signature. We add in vivo evidence of persistent immune activation linked to urate exposure and describe immune pathways involved in the pathogenesis of gout. Our results support a pro-inflammatory effect of asymptomatic hyperuricemia and pave the way for new research into targetable mechanisms in gout and cardiometabolic complications of asymptomatic hyperuricemia.

Abstract
Essential or primary hypertension is a wordwide health problem. Elevated blood pressure (BP) is closely associated not only with increased chronological aging but also with biological aging. There are various common pathways that play a role in cellular aging and BP regulation. These include but not limited to inflammation, oxidative stress, mitochondrial dysfunction, air pollution, decreased klotho activity increased renin angiotensin system activation, gut dysbiosis etc. It has already been shown that some anti-hypertensive drugs have anti-senescent actions and some senolytic drugs have BP lowering effects. In this review, we have summarized the common mechanisms underlying cellular senescence and HT and their relationships. We further reviewed the effect of various antihypertensive medications on cellular senescence and suggest further issues to be studied.

Abstract
Objective Hyperuricemia and gout have become gradually more common. The effect of serum urate on organism aging and systematic inflammation is not determined. This study aims to evaluate whether serum urate is causally associated with cellular aging markers and serum inflammation markers. Methods A Mendelian randomization study was performed on summary-level data from the largest published genome-wide association studies. Single nucleotide polymorphisms with a genome-wide significance level were selected as instrumental variables for leukocyte telomere length (LTL), and serum soluble makers of inflammation (CRP, IL-6, TNF-α, and IGF-1). Standard inverse variance weighted (IVW) method was used as the primary statistical method. The weighted median, MR-Egger regression, and MR-PRESSO methods were used for sensitivity analysis. Results An inverse causal association of genetically predicted serum urate levels and LTL was found using IVW method (OR: 0.96, 95%CI 0.95, 0.97; β=-0.040; SE=0.0072; P=4.37×10-8). The association was also supported by MR results using MR-Egger method and weighted median method. The MR-PRESSO analysis and leave-one-out sensitivity analysis supported the robustness of the combined results. In terms of other aging-related serum biomarkers, there was no evidence supporting a causal effect of serum urate on CRP, IL-6, TNF-α, or IGF-1 levels. Conclusions Serum urate levels are negatively associated with telomere length but are not associated with serum soluble indicators of inflammation. Telomere length may be a critical marker that reflects urate-related organismal aging and may be a mechanism in the age-related pathologies and mortality caused by hyperuricemia.

Association Between Leukocyte Mitochondrial DNA Copy Number and Non-alcoholic Fatty Liver Disease in a Chinese Population Is Mediated by 8-Oxo-2'-Deoxyguanosine. Front Med (Lausanne) 2020; 7:536. [PMID: 33015093 PMCID: PMC7511508 DOI: 10.3389/fmed.2020.00536] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2020] [Accepted: 07/29/2020] [Indexed: 12/30/2022] Open
Abstract
Background: Alterations in mitochondrial DNA are potentially associated with oxidative stress and may be involved in the pathogenesis of non-alcoholic fatty liver disease (NAFLD). However, the association between mitochondrial DNA copy number (mtDNAcn) and NAFLD was not consistent. In addition, the association between inflammation and NAFLD has not been established yet. The present study, based on a Chinese population of individuals with different glucose statuses, aimed to explore the association between leukocyte mtDNAcn, markers of oxidative stress, and inflammation and NAFLD. Methods: A total of 318 participants from a diabetes project were included. NAFLD was diagnosed by ultrasonography. Leukocyte mtDNAcn was determined by PCR assay. The levels of the inflammation markers tumor necrosis factor α (TNF-α) and interleukin 6 (IL-6) and the oxidative stress markers glutathione reductase (GR), superoxide dismutase (SOD), and 8-oxo-2′-deoxyguanosine (8-oxo-dG) were also measured. Results: Participants with NAFLD (n = 105) exhibited significantly higher leukocyte mtDNAcn, IL-6, and 8-oxo-dG (all P < 0.05). Pearson correlation analysis indicated mtDNAcn was negatively associated with age, uric acid, SOD, and TNF-α, but was positively associated with 8-oxo-dG (all P < 0.05). Univariate logistic regression analysis revealed that mtDNAcn was positively associated with NAFLD [odds ratio (OR) = 1.617, 95% confidence interval (CI) = 1.036–2.525; P = 0.034]. However, after adjustment for 8-oxo-dG, this association was no longer statistically significant (OR = 1.534, 95% CI = 0.979–2.403, P = 0.062). Moreover, the stress marker 8-oxo-dG was independently associated with NAFLD after adjustment for mtDNAcn, IL-6, glucose tolerance status, and other conventional NAFLD risk factors (OR = 1.707, 95% CI =1.142–2.550, P = 0.009). Mediation analysis indicated that 8-oxo-dG fully mediated the effect of mtDNAcn on the incidence of NAFLD (direct effect β = 0.5221, 95% CI = −0.0648 to 1.2504; indirect effect β = 0.0946, 95% CI = 0.0049–0.2463). Conclusions: In a Chinese population, the association between leukocyte mtDNAcn and NAFLD was fully mediated by high levels of 8-oxo-dG. Thus, oxidative stress may be an important driver of NAFLD, and clinical interventions aimed at decreasing oxidative stress to improve NAFLD warrant further research.

Gerontology 2020; 66:439-446. [PMID: 32663832 DOI: 10.1159/000508497] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2019] [Accepted: 05/07/2020] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND With the shortening of leukocyte telomere length (LTL) and decrease in the copy number of mitochondrial DNA, mitochondrial dysfunction and oxidative stress are considered important drivers of the aging process. Although previous experimental studies report that caloric intake is associated with age-related renal dysfunction through the changes in mitochondrial function, there are insufficient epidemiological data to establish this association. OBJECTIVE We aimed to explore the association between caloric intake and renal function and to investigate whether mitochondrial DNA copy number (mtDNAcn) mediated this association by cross-sectional analysis. METHODS A total of 403 individuals from a Chinese rural cohort (women = 66.50%; mean age = 53.94 ± 10.27 years) with an estimated glomerular filtration rate (eGFR) ≥60 mL/min/1.73 m2 and with differences in the glucose tolerance status (diabetes, n = 106; prediabetes, n = 125; normal glucose tolerance, n = 172) were included. Dietary data were obtained by a 24-h food recall, and caloric intake was normalized by ideal body weight. The mtDNAcn and LTL were detected using real-time PCR assay. The associations between caloric intake, aging markers, and renal function were analyzed by partial correlation analysis and multiple linear regression analysis. Mediation analysis was applied to examine the role of mtDNAcn in the association between caloric intake and eGFR. RESULTS Caloric intake was higher while age-adjusted mtDNAcn was lower in individuals with eGFR <90 mL/min/1.73 m2 (n = 140) than in those with eGFR ≥90 mL/min/1.73 m2 (n = 263). After adjusting for multiple factors, linear regression analysis revealed that caloric intake was negatively associated with eGFR and mtDNAcn, while mtDNAcn was positively associated with eGFR. Moreover, mediation analysis indicated that the indirect effect of caloric intake on eGFR through mtDNAcn was significant (β = -0.0505, 95% confidence interval -0.0931 to -0.0190). CONCLUSIONS Caloric intake was negatively associated with eGFR in a Chinese population, and the association was partly mediated by decreased mtDNAcn.
