Association between epigenetic age and type 2 diabetes mellitus or glycemic traits: A longitudinal twin study. Aging Cell 2024; 23:e14175. [PMID: 38660768 PMCID: PMC11258448 DOI: 10.1111/acel.14175] [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: 10/10/2023] [Revised: 03/18/2024] [Accepted: 04/04/2024] [Indexed: 04/26/2024] Open
Abstract
Epigenetic clocks based on DNA methylation have been known as biomarkers of aging, including principal component (PC) clocks representing the degree of aging and DunedinPACE representing the pace of aging. Prior studies have shown the associations between epigenetic aging and T2DM, but the results vary by epigenetic age metrics and people. This study explored the associations between epigenetic age metrics and T2DM or glycemic traits, based on 1070 twins (535 twin pairs) from the Chinese National Twin Registry. It also explored the temporal relationships of epigenetic age metrics and glycemic traits in 314 twins (157 twin pairs) who participated in baseline and follow-up visits after a mean of 4.6 years. DNA methylation data were used to calculate epigenetic age metrics, including PCGrimAge acceleration (PCGrimAA), PCPhenoAge acceleration (PCPhenoAA), DunedinPACE, and the longitudinal change rate of PCGrimAge/PCPhenoAge. Mixed-effects and cross-lagged modelling assessed the cross-sectional and temporal relationships between epigenetic age metrics and T2DM or glycemic traits, respectively. In the cross-sectional analysis, positive associations were identified between DunedinPACE and glycemic traits, as well as between PCPhenoAA and fasting plasma glucose, which may be not confounded by shared genetic factors. Cross-lagged models revealed that glycemic traits (fasting plasma glucose, HbA1c, and TyG index) preceded DunedinPACE increases, and TyG index preceded PCGrimAA increases. Glycemic traits are positively associated with epigenetic age metrics, especially DunedinPACE. Glycemic traits preceded the increases in DunedinPACE and PCGrimAA. Lowering the levels of glycemic traits may reduce DunedinPACE and PCGrimAA, thereby mitigating age-related comorbidities.

J Med Biochem 2021; 40:49-59. [PMID: 33584140 PMCID: PMC7857847 DOI: 10.5937/jomb0-24704] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2019] [Accepted: 04/25/2020] [Indexed: 12/25/2022] Open
Abstract
BACKGROUND Till to date whether adiponectin AdipoQ gene variation (rs 1501299) is associated with cardiovascular disease, still remains controversial. Therefore, we aimed to relate the SNP (rs1501299) of adiponectin gene and oxidative stress in context to CVD in Punjabi women of North West India. METHODS In the present case-control study menopausal women with CVD as cases (n=265) and menopausal women without CVD as controls (n=258) were recruited. Genotyping of rs1501299 single nucleotide polymorphism of adiponectin gene was carried out by RFLP-PCR analysis. Biochemical parameters were analyzed according to the standard procedures. RESULTS Distribution of homozygous TT genotype of normolipidemic (p=0.001) and hyperlipidemic (p=0.001) women with CVD was significantly more frequent as compared to women without CVD. rs1501299 T allele carriers with CVD also showed significant (p=0.001) higher frequency distribution as compared to women without CVD. Under recessive model of inheritance TT mutant type homozygotes conferred ~9 fold higher risk [p=0.001; OR= 9.60 (2.92-31.58)] towards CVD susceptibility for MDA>1.50; ~11 fold higher risk [p=0.007; OR= 11.11 (1.49-82.83)] towards CVD for LDL carbonyl protein>15.04 and ~9 fold higher risk [p=0.001; OR= 9.75 (2.30-41.22)] towards CVD susceptibility for SOD≤5.55. Under logistic regression analysis oxidative stress and TT genotype were significantly correlated with CVD. CONCLUSIONS Our study revealed significant association of AdipoQ (rs1501299) gene polymorphism and oxidative stress with cardiovascular disease in Punjabi women of North West India. However, additional studies are required to support these findings.

Abstract
Atherosclerosis-related cardiovascular diseases remain the leading cause of morbidity and mortality, and the search for novel diagnostic and therapeutic methods is ongoing. Mitochondrial DNA (mtDNA) mutations associated with atherosclerosis represent one of the less explored aspects of the disease pathogenesis that may bring some interesting opportunities for establishing novel molecular markers and, possibly, new points of therapeutic intervention. Recent studies have identified a number of mtDNA mutations, for which the heteroplasmy level was positively or negatively associated with atherosclerosis, including the disease at its early, subclinical stages. In this review, we summarize the results of these studies, providing a list of human mtDNA mutations potentially involved in atherosclerosis. The molecular mechanisms underlying such involvement remain to be elucidated, although it is likely that some of them may be responsible for the increased oxidative stress, which plays an important role in atherosclerosis.

Abstract
Our present investigation aimed to determine the neuroprotection of apigenin (API) against diabetes-associated cognitive decline (DACD) a diabetic rat model and exploring its potential mechanism. Diabetic rat model was induced by intraperitoneal injection of streptozotocin. All experiment animals treated with vehicle or API by doses of 10, 20 and 40 mg/kg for seven weeks. Firstly, the body weight and blood glucose levels were detected. We used Morris water maze test to evaluate learning and memory function. The oxidative indicators (malondialdehyde (MDA), superoxide dismutase (SOD) and glutathione (GSH)), cNOS, iNOS, caspase-3 and caspase-9 were measured in cerebral cortex and hippocampus using corresponding commercial kits. API can increase body weight, reduce the blood glucose levels, and improve the cognitive function in rats induced by diabetes. API decrease the MDA content, and increase SOD activity and GSH level of diabetic animals in the cerebral cortex and hippocampus of diabetic rats. Meanwhile, constitutive nitric oxide synthase (cNOS), inducible nitric oxide synthase (iNOS), caspase-3/9 were markedly exhibited in the cerebral cortex and hippocampus of diabetic rats. In summary, our current work discloses that API attenuates DACD in rats via suppressing oxidative stress, nitric oxide and apoptotic cascades synthase pathway.

Coupled aggregation of mitochondrial single-strand DNA-binding protein tagged with Eos fluorescent protein visualizes synchronized activity of mitochondrial nucleoids. Mol Med Rep 2015; 12:5185-90.

Abstract
Oligomer aggregation of green-to-red photoconvertible fluorescent protein Eos (EosFP) is a natural feature of the wild‑type variant. The aim of the present study was to follow up mitochondrial nucleoid behavior under natural conditions of living cells transfected with mitochondrial single‑strand DNA‑binding protein (mtSSB) conjugated with EosFP. HEPG2 and SH‑SY5Y cells were subjected to lentiviral transfection and subsequently immunostained with anti‑DNA, anti‑transcription factor A, mitochondrial (TFAM) or anti‑translocase of the inner membrane 23 antibodies. Fluorescent microscopy, conventional confocal microscopy, superresolution biplane fluorescence photo-activation localization microscopy and direct stochastic optical reconstruction microscopy were used for imaging. In the two cell types, apparent couples of equally‑sized mtSSB‑EosFP‑visualized dots were observed. During the time course of the ongoing transfection procedure, however, a small limited number of large aggregates of mtSSB‑EosFP‑tagged protein started to form in the cells, which exhibited a great co‑localization with the noted coupled positions. Antibody staining and 3D immunocytochemistry confirmed that nucleoid components such as TFAM and DNA were co‑localized with these aggregates. Furthermore, the observed reduction of the mtDNA copy number in mtSSB‑EosFP‑transfected cells suggested a possible impairment of nucleoid function. In conclusion, the present study demonstrated that coupled nucleoids are synchronized by mtSSB‑EosFP overexpression and visualized through their equal binding capacity to mtSSB‑EosFP‑tagged protein. This observation suggested parallel replication and transcription activity of nucleoid couples native from a parental one. Preserved coupling in late stages of artificial EosFP‑mediated aggregation of tagged proteins suggested a rational manner of mitochondrial branching that may be cell-type specifically dependent on hierarchical nucleoid replication.

Abstract
This study was set out to determine the association of serum adiponectin and oxidative stress in newly diagnosed type 2 diabetes patients. 106 patients with newly diagnosed type 2 diabetes were recruited. Simultaneously scanning of the extracranial carotid arteries, common iliac arteries and femoral arteries were performed for measurement of intima media thickness (IMT) in all subjects. Atherosclerotic plaque was defined as IMT value >1.3 mm. The serum levels of adiponectin and 8-iso-prostaglandin F2α (8-iso-PGF2α), a marker of oxidative stress, were examined by enzyme-linked immunosorbent assay. Metabolic parameters were detected by clinical chemistry. According to the results, all of 106 patients with type 2 diabetes were newly diagnosed within 12 months, and aged 60.68±4.32 years. The level of serum adiponectin in newly diagnosed type 2 diabetes patients was lower than that in healthy subjects. Furthermore, type 2 diabetes patients with atherosclerotic plaques had lower serum adiponectin level than those without atherosclerotic plaques. Serum 8-iso-PGF2α level in newly diagnosed type 2 diabetes patients was higher than that in healthy subjects. Further analyses showed that serum adiponectin level was reversely associated with serum 8-iso-PGF2α in newly diagnosed type 2 diabetes patients. Additionally, the atherosclerotic plaques in newly diagnosed type 2 diabetes patients were positively correlated with total cholesterol, but negatively correlated with serum adiponectin level. Taken together, this study suggests that in newly diagnosed type 2 diabetes, serum adiponectin levels are probably associated with oxidative stress and also with the severity of atherosclerosis.
