Synergistic anti-aging effect of Dendrobium officinale polysaccharide and spermidine: A metabolomics analysis focusing on the regulation of lipid, nucleotide and energy metabolism. Int J Biol Macromol 2024; 278:135098. [PMID: 39197612 DOI: 10.1016/j.ijbiomac.2024.135098] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2024] [Revised: 08/23/2024] [Accepted: 08/24/2024] [Indexed: 09/01/2024]
Abstract
The importance of synergy has been underscored in recent medical research for augmenting the efficacy of therapeutic interventions, targeting multiple biological pathways simultaneously. Our prior research elucidated that Dendrobium officinale polysaccharide (DOP) has the potential to prolong the lifespan of Caenorhabditis elegans (C. elegans) via regulating gut microbiota. Concurrently, spermidine (Spd), as a mimicking caloric restriction, facilitates autophagy and exerts a pronounced anti-aging effect. To enhance the anti-aging capabilities of DOP, we conducted a comprehensive study examining the combined effects of DOP and Spd in C. elegans, incorporating metabolomics analysis to investigate the underlying mechanisms. A combination of 250 mg/L DOP and 29.0 mg/L Spd yielded the most favorable outcomes in lifespan extension, evidencing a synergistic effect with a combination index (CI) of 0.65. In oxidative and heat stress tolerance assays, the observed CIs were 0.50 and 0.33, respectively. Metabolomic analysis highlighted significant alterations in metabolites related to lipid, nucleotide and energy metabolism, notably regulating glycerol 3-phosphate, linoleoyl glycerol, docosapentaenoic acid and β-nicotinamide mononucleotide, nicotinamide adenine dinucleotide. The effects of DS on lipid metabolism were further validated using Oil Red O staining and triglyceride level in C. elegans. The results indicated that DS may primarily be via modulating lipid metabolism. To further confirm these findings, a high-fat diet-induced mouse model was employed. Consequently, it can be inferred that the synergistic anti-aging impact of DOP and Spd is likely mediated primarily through alterations in lipid metabolic processes.

Beyond LDL-C: unravelling the residual atherosclerotic cardiovascular disease risk landscape-focus on hypertriglyceridaemia. Front Cardiovasc Med 2024; 11:1389106. [PMID: 39171323 PMCID: PMC11335737 DOI: 10.3389/fcvm.2024.1389106] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2024] [Accepted: 07/08/2024] [Indexed: 08/23/2024] Open
Abstract
Aims Historically, atherosclerotic cardiovascular disease (ASCVD) risk profile mitigation has had a predominant focus on low density lipoprotein cholesterol (LDL-C). In this narrative review we explore the residual ASCVD risk profile beyond LDL-C with a focus on hypertriglyceridaemia, recent clinical trials of therapeutics targeting hypertriglyceridaemia and novel modalities addressing other residual ASCVD risk factors. Findings Hypertriglyceridaemia remains a significant ASCVD risk despite low LDL-C in statin or proprotein convertase subtilisin/kexin type 9 inhibitor-treated patients. Large population-based observational studies have consistently demonstrated an association between hypertriglyceridaemia with ASCVD. This relationship is complicated by the co-existence of low high-density lipoprotein cholesterol. Despite significantly improving atherogenic dyslipidaemia, the most recent clinical trial outcome has cast doubt on the utility of pharmacologically lowering triglyceride concentrations using fibrates. On the other hand, purified eicosapentaenoic acid (EPA), but not in combination with docosahexaenoic acid (DHA), has produced favourable ASCVD outcomes. The outcome of these trials suggests alternate pathways involved in ASCVD risk modulation. Several other pharmacotherapies have been proposed to address other ASCVD risk factors targeting inflammation, thrombotic and metabolic factors. Implications Hypertriglyceridaemia poses a significant residual ASCVD risk in patients already on LDL-C lowering therapy. Results from pharmacologically lowering triglyceride are conflicting. The role of fibrates and combination of EPA and DHA is under question but there is now convincing evidence of ASCVD risk reduction with pure EPA in a subgroup of patients with hypertriglyceridaemia. Clinical guidelines should be updated in line with recent clinical trials evidence. Novel agents targeting non-conventional ASCVD risks need further evaluation.

Abstract
BACKGROUND AND AIMS Obesity and type 2 diabetes are significant risk factors for atherosclerotic cardiovascular disease (CVD) worldwide, but the underlying pathophysiological links are poorly understood. Neurotensin (NT), a 13-amino-acid hormone peptide, facilitates intestinal fat absorption and contributes to obesity in mice fed a high-fat diet. Elevated levels of pro-NT (a stable NT precursor produced in equimolar amounts relative to NT) are associated with obesity, type 2 diabetes, and CVD in humans. Whether NT is a causative factor in CVD is unknown. METHODS Nt+/+ and Nt-/- mice were either injected with adeno-associated virus encoding PCSK9 mutants or crossed with Ldlr-/- mice and fed a Western diet. Atherosclerotic plaques were analyzed by en face analysis, Oil Red O and CD68 staining. In humans, we evaluated the association between baseline pro-NT and growth of carotid bulb thickness after 16.4 years. Lipidomic profiles were analyzed. RESULTS Atherosclerotic plaque formation is attenuated in Nt-deficient mice through mechanisms that are independent of reductions in circulating cholesterol and triglycerides but associated with remodeling of the plasma triglyceride pool. An increasing plasma concentration of pro-NT predicts atherosclerotic events in coronary and cerebral arteries independent of all major traditional risk factors, indicating a strong link between NT and atherosclerosis. This plasma lipid profile analysis confirms the association of pro-NT with remodeling of the plasma triglyceride pool in atherosclerotic events. CONCLUSIONS Our findings are the first to directly link NT to increased atherosclerosis and indicate the potential role for NT in preventive and therapeutic strategies for CVD.

Abstract
BACKGROUND Sensorineural hearing loss (SNHL) is a multifactorial disorder with potential links to various physiological systems, including the cardiovascular system via blood lipid levels such as triglycerides (TG). This study investigates the causal relationship between TG levels and SNHL using Mendelian randomization (MR), which offers a method to reduce confounding and reverse causality by using genetic variants as instrumental variables. METHODS Utilizing publicly available genome-wide association study (GWAS) data, we performed a two-sample MR analysis. The initial analysis unveiled a causal relationship between TG (GWAS ID: ebi-a-GCST90018975) and SNHL (GWAS ID: finn b-H8_HL_SEN-NAS). Subsequent analysis validated this through MR with a larger sample size for TG (GWAS ID: ieu-b-111) and SNHL. To conduct the MR analysis, we utilized several methods including inverse-variance weighted (IVW), MR Egger, weighted median, and weighted mode. We also employed Cochrane's Q test to identify any heterogeneity in the MR results. To detect horizontal pleiotropy, we conducted the MR-Egger intercept test and MR pleiotropy residual sum and outliers (MR-PRESSO) test. We performed a leave-one-out analysis to assess the sensitivity of this association. Finally, a meta-analysis of the MR results was undertaken. RESULTS Our study found a significant positive correlation between TG and SNHL, with OR values of 1.14 (95% CI: 1.07-1.23, p < 0.001) in the IVW analysis and 1.09 (95% CI: 1.03-1.16, p < 0.006) in the replicate analysis. We also found no evidence of horizontal pleiotropy or heterogeneity between the genetic variants (p > 0.05), and a leave-one-out test confirmed the stability and robustness of this association. The meta-analysis combining the initial and replicate analyses showed a significant causal effect with OR values of 1.11 (95% CI: 1.06-1.16, p = 0.01). CONCLUSION These findings indicate TG as a risk factor for SNHL, suggesting potential pathways for prevention and intervention in populations at risk. This conclusion underscores the importance of managing TG levels as a strategy to mitigate the risk of developing SNHL.

Abstract
There is a substantial rise in the global incidence of obesity. Brown rice contains metabolic substances that can help minimize the prevalence of obesity. This study evaluated nine brown rice varieties using probiotic fermentation using Pediococcus acidilacti MNL5 to enhance bioactive metabolites and their efficacy. Among the nine varieties, FBR-1741 had the highest pancreatic lipase inhibitory efficacy (87.6 ± 1.51%), DPPH assay (358.5 ± 2.80 mg Trolox equiv./100 g, DW), and ABTS assay (362.5 ± 2.32 mg Trolox equiv./100 g, DW). Compared to other fermented brown rice and FBR-1741 varieties, UHPLC-Q-TOF-MS/MS demonstrated significant untargeted metabolite alterations. The 17 most abundant polyphenolic metabolites in the FBR-1741 variety and 132 putative targets were assessed for obesity-related target proteins, and protein interaction networks were constructed using the Cystoscope software. Network pharmacology analysis validated FBR-1741 with active metabolites in the C. elegans obesity-induced model. Administration of FBR-1741 with ferulic acid improved lifespan decreased triglycerides, and suppressed the expression of fat-related genes. The enhanced anti-obesity properties of FBR-1741 suggest its implementation in obesity-functional food.

Metab Syndr Relat Disord 2023; 21:526-534.

Abstract
Background: Previous evidence has demonstrated that elevated low-density lipoprotein cholesterol (LDL-C) was associated with atherosclerosis. However, there is scarce population-based evidence for the role of remnant cholesterol (remnant-C) in arterial stiffness, an imaging marker for subclinical atherosclerosis. Herein, we aimed to evaluate the correlation of remnant-C with arterial stiffness beyond LDL-C in a check-up population. Methods: The study included consecutive subjects who visited the Murakami Memorial Hospital for health check-ups between 2004 and 2012. The calculation of remnant-C occurred as total cholesterol minus high-density lipoprotein cholesterol (HDL-C) minus LDL-C. The brachial-ankle pulse wave velocity (baPWV) >1400 cm/sec was defined as arterial stiffness or baPWV abnormality. The independent correlation of remnant-C level to arterial stiffness was evaluated using adjusted regression models. Results: A total of 909 participants were included (mean age 51.1 ± 9.6 years, male sex 64.9%). In multivariate linear regression analyses, remnant-C remained an independent predictor of the baPWV predictor [β: 94.76, 95% confidence interval (CI) 42.19-147.33, P < 0.001] after adjusting for confounders. After multivariable adjustment, including LDL-C, the highest remnant-C quartile odd ratio (OR) (95% CI) was 2.79 (1.27-6.09) for baPWV abnormality compared to the lowest quartile. Furthermore, each 10-mg/dL increase in remnant-C correlated with a 28% increased risk for baPWV abnormality (OR: 1.28, 95% CI: 1.04-1.57). Moreover, the correlation between remnant-C and baPWV abnormality was still significant in the participant subgroup with optimal levels of LDL-C. Conclusions: Our findings demonstrated that remnant-C levels correlated to arterial stiffness with the dependence of LDL-C and other cardiovascular risk factors in a check-up population.

Abstract
Background The atherosclerotic effect of an adverse lipid profile is assumed to accumulate throughout life, leading to increased risk of myocardial infarction (MI). Still, little is known about age at onset and duration of unfavorable lipid levels before MI. Methods and Results Longitudinal data on serum lipid levels for 26 130 individuals (50.5% women, aged 20-89 years) were obtained from 7 population-based health surveys in Tromsø, Norway. Diagnoses of MI were obtained from national registers. A linear mixed model was applied to compare age- and sex-specific mean values of total cholesterol, high-density lipoprotein cholesterol (HDL-C), and triglyceride concentration by MI status (MI versus non-MI). Already from young adulthood, 20 to 35 years before the incident MI, individuals with a subsequent incident MI had on average more adverse lipid levels than individuals of the same age and sex without MI. Analogous to a dose-response relationship, there was a clear trend toward more severe adverse lipid levels the lower the age at incident MI (P<0.001, test for trend through ordered categories <55, 55-74, ≥75 years). This trend was particularly pronounced for high-density lipoprotein cholesterol in percentage of total cholesterol (both sexes) and for the relative relationship between triglyceride, high-density lipoprotein cholesterol, and total cholesterol level (women). The difference in mean lipid level by MI status was just as large in women as in men, but the age pattern differed (P≤0.05, tests of 3-way interaction). Conclusions Compared with general population mean levels, adverse lipid levels were seen 20 to 35 years before the incident MI in both men and women.

Abstract
Aging is a process of progressive deterioration of multiple physiological functions within an organism. This study investigated the anti-aging effects of polysaccharides extracted from ginsenoside residues (GRP) in Caenorhabditis elegans using physiological, microbiomic, and transcriptomic approaches. GRP treatment prolonged the mean lifespan of C. elegans by 58.60 % (19.64 days) and did not affect locomotive behaviors. It reduced levels of lipofuscin and reactive oxygen species (ROS), and increased superoxide dismutase activity, which prevented oxidative damage caused by aging. Microbiomic data indicated that GRP administration significantly altered the composition of gut flora and increased the abundance of beneficial bacteria. Transcriptomic analyses identified 201 differentially expressed genes (DEGs). GRP treatment may enhance fatty acid degradation and induce preferential synthesis of beneficial fatty acids. It may also activate the metabolism of certain amino acids. The transcriptomic data were reliably reproduced using seven vital DEGs, which were confirmed by qRT-PCR analysis. These findings show that GRP has positive effects that prolong lifespan and alleviate aging in C. elegans. GRP should be explored as an effective dietary supplement for the development of functional foods. We propose a potentially novel mechanism that more fully describes the anti-aging mechanisms induced by GRP.

Abstract
Atherosclerosis is still considered a disease burden with long-term damaging processes towards the cardiovascular system. Evaluation of atherosclerotic stages requires the use of independent markers such as those already considered traditional, that remain the main therapeutic target for patients with atherosclerosis, together with emerging biomarkers. The challenge is finding models of predictive markers that are particularly tailored to detect and evaluate the evolution of incipient vascular lesions. Important advances have been made in this field, resulting in a more comprehensible and stronger linkage between the lipidic profile and the continuous inflammatory process. In this paper, we analysed the most recent data from the literature studying the molecular mechanisms of biomarkers and their involvement in the cascade of events that occur in the pathophysiology of atherosclerosis.
