Biomarkers of aging in frailty and age-associated disorders: State of the art and future perspective. Ageing Res Rev 2023; 91:102044. [PMID: 37647997 DOI: 10.1016/j.arr.2023.102044] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2023] [Revised: 08/24/2023] [Accepted: 08/25/2023] [Indexed: 09/01/2023]
Abstract
According to the Geroscience concept that organismal aging and age-associated diseases share the same basic molecular mechanisms, the identification of biomarkers of age that can efficiently classify people as biologically older (or younger) than their chronological (i.e. calendar) age is becoming of paramount importance. These people will be in fact at higher (or lower) risk for many different age-associated diseases, including cardiovascular diseases, neurodegeneration, cancer, etc. In turn, patients suffering from these diseases are biologically older than healthy age-matched individuals. Many biomarkers that correlate with age have been described so far. The aim of the present review is to discuss the usefulness of some of these biomarkers (especially soluble, circulating ones) in order to identify frail patients, possibly before the appearance of clinical symptoms, as well as patients at risk for age-associated diseases. An overview of selected biomarkers will be discussed in this regard, in particular we will focus on biomarkers related to metabolic stress response, inflammation, and cell death (in particular in neurodegeneration), all phenomena connected to inflammaging (chronic, low-grade, age-associated inflammation). In the second part of the review, next-generation markers such as extracellular vesicles and their cargos, epigenetic markers and gut microbiota composition, will be discussed. Since recent progresses in omics techniques have allowed an exponential increase in the production of laboratory data also in the field of biomarkers of age, making it difficult to extract biological meaning from the huge mass of available data, Artificial Intelligence (AI) approaches will be discussed as an increasingly important strategy for extracting knowledge from raw data and providing practitioners with actionable information to treat patients.

Dynamics of the Levels of Interleukin 6, Its Soluble Receptor, and Soluble Glycoprotein 130 in Patients with Chronic Heart Failure and Preserved or Reduced Ejection Fraction. Bull Exp Biol Med 2023; 174:666-669.

Abstract
The features of IL-6 trans-signaling were studied in patients with heart failure with reduced (n=74) and preserved (n=31) ejection fraction (EF) during acute decompensation of HF (ADHF) and after 1 year. Patients with ADHF with reduced EF demonstrated higher levels of IL-6 and soluble glycoprotein 130 in comparison with those in patients with preserved EF: 10.18 (7.07; 16.14) pg/ml vs 6.35 (3.52; 11.00) pg/ml and 543.46 (455.37; 634.43) ng/ml vs 498.50 (408.16; 632.23) ng/ml, respectively. The levels of soluble IL-6 receptor little differed in these groups: 57.82 (47.55; 79.85) ng/ml vs 61.30 (44.97; 78.08) ng/ml. After 1 year, the levels of IL-6 in HF patients with reduced EF significantly decreased (5.36 (3.35; 8.35) pg/ml), while in patients with preserved EF, the decrease in this parameter was less pronounced (5.86 (4.05; 7.32) pg/ml), and the difference between groups disappeared. The levels of soluble glycoprotein 130 increased in both groups: 448.06 (357.74; 550.67) ng/ml vs 385.35 (344.29; 523.72) ng/ml. It should be noted that after 1 year (in stable patients), the levels of soluble IL-6 receptor increased in both groups: 65.75 (54.84; 75.39) ng/ml vs 70.81 (57.51; 82.25) ng/ml. Thus, despite the high levels of IL-6 in HF patients with reduced EF, the potential limiting IL-6 trans-signaling in these patients is higher than in patients with preserved EF.

Decreased Serum Levels of Soluble Oncostatin M Receptor (sOSMR) and Glycoprotein 130 (sgp130) in Patients with Coronary Artery Disease. Arq Bras Cardiol 2023; 120:e20220326. [PMID: 37098986 PMCID: PMC10263435 DOI: 10.36660/abc.20220326] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2022] [Revised: 12/11/2022] [Accepted: 12/14/2022] [Indexed: 04/08/2023] Open
Abstract
BACKGROUND Oncostatin M (OSM) is a pleiotropic cytokine which, after arterial injury, has proven to be to be rapidly expressed. OBJECTIVES To correlate the serum levels of OSM, soluble OSM receptor (sOSMR), and soluble fraction of glycoprotein 130 (sgp130) in patients with coronary artery disease (CAD) with clinical parameters. METHODS Levels of sOSMR and sgp130 were evaluated by ELISA and OSM by Western Blot, in patients with CCS (n=100), patients with ACS (n=70), and 64 control volunteers without clinical manifestations of the disease. P-values < 0.05 were considered to be statistically significant. RESULTS CAD patients exhibited significantly lower levels of sOSMR and sgp130 and higher levels of OSM when compared to the controls (both p < 0.0001). Clinical analysis displayed, lower levels of sOSMR in men ([OR] = 2.05, p = 0.026), youth (OR = 1.68, p = 0.0272), hypertensives (OR = 2.19, p = 0.041), smokers (OR = 2.19, p = 0.017), patients that did not present dyslipidemia (OR = 2.32, p = 0.013), patients with Acute Myocardial Infarction [AMI] (OR = 3.01, p = 0.001) and patients not treated with statin (OR = 1.95, p = 0.031), antiplatelet agent (OR = 2.46, p = 0.005), inhibitors of calcium channels (OR = 3.15, p = 0.028), and antidiabetic drugs (OR = 2.97, p = 0.005). The levels of sOSMR were also correlated with gender, age, hypertension, and use of medications in multivariate analysis. CONCLUSIONS Our data suggest that the enhanced serum levels of OSM, and decreased levels of sOSMR and sGP130 in patients with cardiac injury may play an important role in the pathophysiological mechanism of the disease. Furthermore, lower levels of sOSMR were associated with gender, age, hypertension, and the use of medications.

Time to run: Late rather than early exercise training in mice remodels the gut microbiome and reduces atherosclerosis development. FASEB J 2023; 37:e22719.

Abstract
The metabolic and inflammatory processes that are implicated in the development of cardiovascular diseases are under control of the biological clock. While skeletal muscle function exhibits circadian rhythms, it is unclear to what extent the beneficial health effects of exercise are restricted to unique time windows. We aimed to study whether the timing of exercise training differentially modulates the development of atherosclerosis and elucidate underlying mechanisms. We endurance-trained atherosclerosis-prone female APOE*3-Leiden.CETP mice fed a Western-type diet, a well-established human-like model for cardiometabolic diseases, for 1 h five times a week for 4 weeks either in their early or in their late active phase on a treadmill. We monitored metabolic parameters, the development of atherosclerotic lesions in the aortic root and assessed the composition of the gut microbiota. Late, but not early, exercise training reduced fat mass by 19% and the size of early-stage atherosclerotic lesions by as much as 29% compared to sedentary animals. No correlation between cholesterol exposure and lesion size was evident, as no differences in plasma lipid levels were observed, but circulating levels of the pro-inflammatory markers ICAM-1 and VCAM-1 were reduced with late exercise. Strikingly, we observed a time-of-day-dependent effect of exercise training on the composition of the gut microbiota as only late training increased the abundance of gut bacteria producing short-chain fatty acids with proposed anti-inflammatory properties. Together, these findings indicate that timing is a critical factor to the beneficial anti-atherosclerotic effects of exercise with a great potential to further optimize training recommendations for patients.

Abstract
Atherosclerosis is a chronic inflammatory disease that poses a huge economic burden due to its extremely poor prognosis. Therefore, it is necessary to explore potential mechanisms to improve the prevention and treatment of atherosclerosis. A disintegrin and metalloprotease 17 (ADAM17) is a cell membrane-bound protein that performs a range of functions through membrane protein shedding and intracellular signaling. ADAM17-mediated inflammation has been identified to be an important contributor to atherosclerosis; however, the specific relationship between its multiple regulatory roles and the pathogenesis of atherosclerosis remains unclear. Here, we reviewed the activation, function, and regulation of ADAM17, described in detail the role of ADAM17-mediated inflammatory damage in atherosclerosis, and discussed several controversial points. We hope that these insights into ADAM17 biology will lead to rational management of atherosclerosis. ADAM17 promotes vascular inflammation in endothelial cells, smooth muscle cells, and macrophages, and regulates the occurrence and development of atherosclerosis.

A Meta-Analysis of Human Transcriptomics Data in the Context of Peritoneal Dialysis Identifies Novel Receptor-Ligand Interactions as Potential Therapeutic Targets. Int J Mol Sci 2021; 22:ijms222413277. [PMID: 34948074 PMCID: PMC8703997 DOI: 10.3390/ijms222413277] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2021] [Revised: 12/01/2021] [Accepted: 12/08/2021] [Indexed: 11/16/2022] Open
Abstract
Peritoneal dialysis (PD) is one therapeutic option for patients with end-stage kidney disease (ESKD). Molecular profiling of samples from PD patients using different Omics technologies has led to the discovery of dysregulated molecular processes due to PD treatment in recent years. In particular, a number of transcriptomics (TX) datasets are currently available in the public domain in the context of PD. We set out to perform a meta-analysis of TX datasets to identify dysregulated receptor-ligand interactions in the context of PD-associated complications. We consolidated transcriptomics profiles from twelve untargeted genome-wide gene expression studies focusing on human cell cultures or samples from human PD patients. Gene set enrichment analysis was used to identify enriched biological processes. Receptor-ligand interactions were identified using data from CellPhoneDB. We identified 2591 unique differentially expressed genes in the twelve PD studies. Key enriched biological processes included angiogenesis, cell adhesion, extracellular matrix organization, and inflammatory response. We identified 70 receptor-ligand interaction pairs, with both interaction partners being dysregulated on the transcriptional level in one of the investigated tissues in the context of PD. Novel receptor-ligand interactions without prior annotation in the context of PD included BMPR2-GDF6, FZD4-WNT7B, ACKR2-CCL2, or the binding of EPGN and EREG to the EGFR, as well as the binding of SEMA6D to the receptors KDR and TYROBP. In summary, we have consolidated human transcriptomics datasets from twelve studies in the context of PD and identified sets of novel receptor-ligand pairs being dysregulated in the context of PD that warrant investigation in future functional studies.

Abstract
Systemic inflammation is characterized by the induction of pro-inflammatory cytokines, the increased level of which in the blood of patients with chronic heart failure (CHF) correlates with unfavorable clinical outcomes. However, it is unclear whether pro-inflammatory cytokines are the cause or the consequence of the disease progression. CHF with preserved ejection fraction and CHF with reduced ejection fraction demonstrate different inflammatory features, which suggests different degrees of pro-inflammatory pathway activation. The review deals with participation of pro-inflammatory cytokines in pathophysiological processes of CHF development, emphasizing the role of interleukin-6 activation and the effects of accompanying diseases on the course of systemic inflammation. The search for new approaches to prevention and therapy of CHF remains actual. The review presents the results of clinical trials of targeted anti-cytokine therapy which have revealed difficulties in controlling inflammation under the conditions of CHF. Identification of specific pro-inflammatory pathways in CHF pathogenesis will allow one to control inflammatory cascades, thus providing a prospective therapeutic strategy.

Abstract
The pleiotropic cytokine interleukin-6 (IL-6) is involved in numerous physiological and pathophysiological functions that include development, immune cell differentiation, inflammation and cancer. IL-6 can signal via the membrane-bound IL-6 receptor (IL-6R, classic signaling) or via soluble forms of the IL-6R (sIL-6R, trans-signaling). Both modes of signaling induce the formation of a homodimer of the signal transducing β-receptor glycoprotein 130 (gp130) and the activation of several intracellular signaling cascades, e.g. the Jak/STAT pathway. Intriguingly, only IL-6 trans-signaling is required for the pro-inflammatory properties of IL-6, while regenerative and anti-inflammatory functions are mediated via classic signaling. The sIL-6R is generated by different molecular mechanisms, including alternative mRNA splicing, proteolysis of the membrane-bound IL-6R and the release of extracellular vesicles. In this review, we give an in-depth overview on these molecular mechanisms with a special emphasize on IL-6R cleavage by the metalloprotease ADAM17 and other proteases. We discuss the biological functions of the sIL-6R and highlight attempts to selectively block IL-6 trans-signaling in pre-clinical animal models as well as in clinical studies in patients with inflammatory bowel disease.

J Mol Med (Berl) 2021; 99:1009-1020.

Abstract
IL-6 has been suggested to function as an autocrine mitogen in the psoriatic epidermis. The biological activity of IL-6 relies on interactions with its receptors, including the membrane-bound IL-6 receptor (mIL-6R) and soluble IL-6 receptor (sIL-6R). Our study presents data showing that the levels of plasma IL-6 and sIL-6R were elevated in psoriatic patients. Genotyping of two single-nucleotide polymorphisms (SNPs) in IL-6R (rs4845617 and rs2228145) demonstrated that the SNP IL-6R (rs4845617) rather than IL-6R (rs2228145) shows a significant association with psoriasis (P = 0.006). To verify the functions of sIL-6R, cultured keratinocytes and imiquimod (IMQ)-induced psoriatic model mice were treated with sIL-6R. We found that the presence of sIL-6R in the HaCaT cell culture medium enhanced the IL-6-induced Stat3 activation, which resulted in abnormal keratinocyte proliferation and aberrant differentiation. Furthermore, the application of sIL-6R in vivo accelerated the pathological development of the disease. Our results demonstrate for the first time that genetic polymorphisms in the IL-6R gene are associated with psoriasis disease phenotypes in a Chinese psoriatic patient population; sIL-6R-mediated trans-signaling pathway plays a pivotal role in keratinocyte proliferation and differentiation, suggesting potential therapeutics for psoriasis. KEY MESSAGES: Patients with psoriasis displayed higher levels of IL-6 and sIL-6R compared with healthy controls. Analysis of genotypes revealed that IL-6R rs4845617 GG genotype associated with the risk of psoriasis. Supplement of sIL-6R further enhanced IL-6-induced Stat3 activation in keratinocytes. In vivo administration of sIL-6R accelerated, whereas sgp130FC alleviated, the pathological development of psoriasis.

Mycobacterium tuberculosis-stimulated whole blood culture to detect host biosignatures for tuberculosis treatment response. Tuberculosis (Edinb) 2021; 128:102082. [PMID: 33865162 PMCID: PMC8192498 DOI: 10.1016/j.tube.2021.102082] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2020] [Revised: 03/26/2021] [Accepted: 04/01/2021] [Indexed: 10/21/2022]
Abstract
Host markers to monitor the response to tuberculosis (TB) therapy hold some promise. We evaluated the changes in concentration of Mycobacterium tuberculosis (M.tb)-induced soluble biomarkers during early treatment for predicting short- and long-term treatment outcomes. Whole blood samples from 30 cured and 12 relapsed TB patients from diagnosis, week 1, 2, and 4 of treatment were cultured in the presence of live M.tb for seven days and patients followed up for 24 weeks after the end of treatment. 57 markers were measured in unstimulated and antigen-stimulated culture supernatants using Luminex assays. Top performing multi-variable models at diagnosis using unstimulated values predicted outcome at 24 months after treatment completion with a sensitivity of 75.0% (95% CI, 42.8-94.5%) and specificity of 72.4% (95% CI, 52.8-87.3%) in leave-one-out cross validation. Month two treatment responder classification was correctly predicted with a sensitivity of 79.2% (95% CI, 57.8-92.9%) and specificity of 92.3% (95% CI, 64.0-99.8%). This study provides evidence of the early M.tb-specific treatment response in TB patients but shows that the observed unstimulated marker models are not outperformed by stimulated marker models. Performance of unstimulated predictive host marker signatures is promising and requires validation in larger studies.

Abstract
The coronavirus disease 19 (COVID-19) pandemic poses a serious global threat to human health and the economy. Based on accumulating evidence, its continuous progression involves not only pulmonary injury but also damage to the cardiovascular system due to intertwined pathophysiological risks. As a point of convergence in the pathophysiologic process between COVID-19 and heart failure (HF), cytokine storm induces the progression of COVID-19 in patients presenting pre-existing or new onset myocardial damage and even HF. Cytokine storm, as a trigger of the progression of HF in patients with COVID-19, has become a novel focus to explore therapies for target populations. In this review, we briefly introduce the basis of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and illuminate the mechanism and links among COVID-19, cytokine storm, and HF. Furthermore, we discuss drugs and therapeutic targets for patients with COVID-19 and HF.

ANNALS OF TRANSLATIONAL MEDICINE 2020; 8:379.

Abstract
Background As a major inflammatory pathway in coronary artery disease (CAD), IL-6 trans-signaling is activated by the IL-6: sIL-6Rα binary complex (B) and inhibited by sgp130 through forming the IL-6: sIL-6Rα: sgp130 ternary complex (T). The aim of the present study was to examine the possible relationship between biomarkers mirroring the IL-6-neutralizing sIL-6R-sgp130 buffer system and CAD in postmenopausal women. Methods Our study recruited 155 CAD patients and 181 controls among postmenopausal women. Circulating levels of IL-6, sIL-6Rα and sgp130 were detected using an enzyme-linked immunosorbent assay, and the B/T ratio was calculated by the specific formulas. Results CAD patients showed significantly higher circulating levels of IL-6 and sIL-6Rα, significantly higher B/T ratio, and significantly lower sgp130 levels than controls (all P<0.05). Spearman’s correlation analysis indicated that IL-6 levels (r=0.185, P<0.01) and B/T ratio (r=0.319, P<0.01) were positively related to Gensini scores, while elevated sgp130 levels were significantly associated with decreased Gensini scores (r=−0.565, P<0.001). In addition, multiple regression analysis showed that Gensini scores were negatively associated with serum sgp130 levels (β-coefficient =−0.318, P<0.001) and had a positive association with IL-6 levels (β-coefficient =0.138, P<0.05). Multivariate logistic regression analysis identified that after adjusting for confounding factors, higher sgp130 remained an independent predictor of lower incidence of CAD in women after menopause (OR =0.904; 95% CI: 0.837–0.976, P=0.010). Moreover, sgp130 levels at 136.01 ng/mL (AUC =0.957, 95% CI: 0.928–0.986, P<0.001) and B/T ratio at 1.51 (AUC =0.765; 95% CI: 0.702–0.828, P<0.001) were effective cut-off points to determine the presence of CAD based on receiver operating characteristic curves. Conclusions Based on this small case-control study, sgp130 and B/T ratio in the IL-6-neutralizing sIL-6R-sgp130 buffer system may be promising biomarkers for CAD diagnosis and assessments of coronary stenosis severity in postmenopausal women.

Abstract
Aims The pro-inflammatory response to interleukin 6 (IL6) trans-signalling in atherosclerosis is driven by the IL6 and soluble IL6 receptor (sIL6R) binary complex. The binary IL6:sIL6R complex is inactivated by sgp130 through the formation of the ternary IL6:sIL6R:sgp130 complex. The aim of this study was to investigate if IL6 trans-signalling, estimated by a ratio between the binary and ternary complexes, associates with the risk of future cardiovascular events (CVE) in a Swedish cohort of 60-year-old men and women (n = 4232). Methods and results Binary and ternary complex levels expressed in nanomol/Litre were derived from serum concentrations of IL6, sIL6R, and sgp130. Cox regression models were used to assess the risk of CVE (myocardial infarction, angina pectoris, and ischaemic stroke, n = 525), expressed as hazard ratio (HR) with 95% confidence interval (CI), associated with increasing circulating levels of the three molecules and with the binary/ternary complex ratio. Estimates were adjusted for the common cardiovascular (CV) risk factors. To assess the level of IL6-trans-signalling, we estimated the binary/ternary complex ratio and then analysed the association with CVE risk. A ratio higher than the median, representing a relative excess of the active binary complex was associated with increased CVE risk (adjusted HR 1.44, 95% CI 1.21-1.72). Conclusion The ratio between the functional moieties of IL6 trans-signalling, IL6:sIL6R, and IL6:sIL6R:sgp130, was associated with CVE risk indicating that it could be a promising marker of CV risk and possibly be used in selecting patients for anti-inflammatory therapy.
