Abstract
The nutritional role of zinc (Zn) and boron (B) in the plant-animal-human food chain is highly topical worldwide research. Our data indicated that Zn-B complex (ZBC)-based dietary supplements can be used as stable non-toxic formulations, with high intestinal absorption rate, inducing alpha2-macroglobulin (A2M) expression for longevity and healthy life. ZBC is metabolized by hydrolysis, mainly at the absorption site (intestinal level), and most of it is excreted in the urine. Within seven hours from the administration in mice, almost the entire amount of orally absorbed ZBC is eliminated in a metabolized form. The highest amount of A2M protein in mouse liver was determined by immunoabsorbance assay in the chronic experiment (1000mg/kg of ZBC), followed by the subchronic experiment (at the same dose of ZBC), and by the acute experiment (5000mg/kg of ZBC).

Potential anti-cancer effects of hibernating common carp (Cyprinus carpio) plasma on B16-F10 murine melanoma: In vitro and in vivo studies. Int J Biol Macromol 2023; 238:124058. [PMID: 36931484 DOI: 10.1016/j.ijbiomac.2023.124058] [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: 04/23/2022] [Revised: 03/12/2023] [Accepted: 03/13/2023] [Indexed: 03/17/2023]
Abstract
Melanoma is the major type of skin cancer, which its treatment is still a challenge in the world. In recent years, interest in hibernation-based therapeutic approaches for various biomedical applications has been increased. Many studies indicated that some factors in the blood plasma of hibernating animals such as alpha-2-macroglobulin (A2M) cause anti-proliferative effects. Considering that, the present study was conducted to investigate the anti-cancer effects of hibernating common carp plasma (HCCP) on murine melanoma (B16-F10) in vitro and in vivo. The effect of HCCP on cell viability, migration, apoptosis rate, and cell cycle distribution of B16-F10 cells, tumor growth, and rate of survival were evaluated. To investigate the role of A2M in the anti-cancer effects of HCCP, the gene of interest and proteins in HCCP and non-hibernating common carp plasma (NHCCP) were evaluated by quantitative reverse transcription-polymerase chain reaction (qRT-PCR) assay as well as sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and mass spectrometry analysis. Based on our findings, HCCP significantly decreased B16-F10 cell viability. Moreover, HCCP caused morphological alternations, inhibition of migration, induction of apoptosis, and significantly induced the cell cycle arrest at the G2/M phase. In addition, A2M level was significantly increased in HCCP compared with NHCCP. Taken together, our findings suggested that HCCP had the potential to be a promising novel therapeutic target for cancer treatment because of its anti-cancer properties.

Abstract
Extracellular vesicles (EVs) derived from urine are promising tools for the diagnosis of urogenital cancers. Urinary EVs (uEVs) are considered potential biomarkers for bladder cancer (BC) because urine is in direct contact with the BC tumor microenvironment and thus reflects the current state of the disease. However, challenges associated with the effective isolation and analysis of uEVs complicate the clinical detection of uEV-associated protein biomarkers. Herein, we identified uEV-derived alpha-2-macroglobulin (a2M) as a novel diagnostic biomarker for BC through comparative analysis of uEVs obtained from patients with BC pre- and post-operation using an antibody array. Furthermore, enzyme-linked immunosorbent assay of uEVs isolated from patients with BC (n=60) and non-cancer control subjects (n=23) validated the significant upregulation of a2M expression in patient uEVs (p<0.0001). There was no significant difference in whole urine a2M levels between patients with BC and controls (p=0.317). We observed that compared to classical differential centrifugation, ExoDisc, a centrifugal microfluidic tangential flow filtration device, was a significantly more effective separation method for uEV protein analysis. We expect that our approach for EV analysis will provide an efficient route for the identification of clinically meaningful uEV-based biomarkers for cancer diagnosis.

Abstract
The objective of the present study was assessment of the major copper and zinc species in dairy cow blood serum using a hybrid high-performance liquid chromatography-inductively coupled plasma-mass spectrometry (HPLC-ICP-MS) technique. A total of seventeen 5-6-year-old female Simmental cows, cultivated in the Southern Ural region, were examined. Speciation of serum Cu and Zn was performed using chromatographic PerkinElmer Series 200 system equipped with Agilent Bio SEC-5 Column and docked with NexION 300D mass spectrometer. Analysis of serum 63Cu species revealed four major fractions containing 2.5% (A), 15.6% (B), 75.6% (C), and 11.9% (D) of total copper levels. The revealed fractions could be assigned to tetrameric and dimeric macroglobulin, ceruloplasmin, albumin, and low molecular mass (LMM) copper compounds, respectively. Minor fraction (E) containing <1% of total serum Cu levels may be represented by low-molecular mass Cu species. Speciation analysis also revealed four Zn fractions containing 6.3% (A), 16.9% (B), 71% (C), and 3% (D) of total Zn levels that may be attributed to zinc-bound tetrameric and dimeric macroglobulin, albumin, and Zn-amino acid compounds. Correlation analysis demonstrated that relative levels (%) of Zn-B (dimeric α2-macroglobulin), Zn-C (albumin), and Zn-D (LMM) fractions correlate inversely with Cu-A (monomeric α2-macroglobulin) (r = -0.600), Cu-D (albumin) (r = -0.696), and Cu-C (ceruloplasmin) (r = -0.652), respectively. The obtained data demonstrate the particular features of Zn and Cu transport in dairy cows that may be used for assessment of dietary status of trace elements.

Abstract
Most research on mechanisms of aging is being conducted in a very limited number of classical model species, i.e., laboratory mouse (Mus musculus), rat (Rattus norvegicus domestica), the common fruit fly (Drosophila melanogaster) and roundworm (Caenorhabditis elegans). The obvious advantages of using these models are access to resources such as strains with known genetic properties, high-quality genomic and transcriptomic sequencing data, versatile experimental manipulation capabilities including well-established genome editing tools, as well as extensive experience in husbandry. However, this approach may introduce interpretation biases due to the specific characteristics of the investigated species, which may lead to inappropriate, or even false, generalization. For example, it is still unclear to what extent knowledge of aging mechanisms gained in short-lived model organisms is transferable to long-lived species such as humans. In addition, other specific adaptations favoring a long and healthy life from the immense evolutionary toolbox may be entirely missed. In this review, we summarize the specific characteristics of emerging animal models that have attracted the attention of gerontologists, we provide an overview of the available data and resources related to these models, and we summarize important insights gained from them in recent years. The models presented include short-lived ones such as killifish (Nothobranchius furzeri), long-lived ones such as primates (Callithrix jacchus, Cebus imitator, Macaca mulatta), bathyergid mole-rats (Heterocephalus glaber, Fukomys spp.), bats (Myotis spp.), birds, olms (Proteus anguinus), turtles, greenland sharks, bivalves (Arctica islandica), and potentially non-aging ones such as Hydra and Planaria.

Abstract
Glycosaminoglycans (GAGs) have been used to diminish the deleterious effects associated with aging by preventing the destruction of cartilage, bone, discs, and skin. The objective of this study was to evaluate the anti-aging effect of a newly prepared GAG derived from bumblebee (Bombus terrestris) queen (BTQG, 10 mg/kg). Gryllus bimaculatus (Gb, cricket) GAG (GbG, 10 mg/kg) or glucosamine sulfate (GS) was used as a positive control. N-glycans derived from BTQG contained hexose polymers including Hex4HexNAc3Pen1, Hex9, and Hex5HexNAc3dHex2 as the primary components. The GAGs were intraperitoneally administered to 14-month-old aged rats for 1 month. BTQG reduced the serum levels of free fatty acid, alkaline phosphatase (ALP), glutamate pyruvate transaminase (GPT), creatinine, and blood urea nitrogen (BUN), showing hepato-and renal-protective effects with anti-lipidemic activities comparable to GS. The changes of gene expression profile of liver tissue by cDNA microarray showed the simultaneous upregulation of 36 genes in the BTQG-treated rat group compared to the control group, including secretogranin II (Scg2), Activator (AP)-1-regulated protein-related reactive oxygen species (ROS) DNA damage repair, metallothionein 1a, and alpha-2 macroglobulin. The BTQG-treated group also showed 417 downregulated genes, including vimentin, moesin, and mitochondrial carbonic anhydrase. Insect glycosaminoglycan from the bumblebee (B. terrestris) queen may help decelerate the aging stage by ameliorating the aging effects on circulation, and liver and kidney function.

Abstract
Many streptococcal strains bind to two main human blood plasma proteins: IgG and human serum albumin (HSA). Protein G expressed in group C and G streptococci has specific binding regions for these proteins. Protein G in group G streptococcal strains also contains a region binding another human plasma protein, α2-macroglobulin (α2-М), upstream to the HSA-binding domain. Two recombinant polypeptides GM and GM1 capable of binding to α2-М were obtained using the G4223 strain of a group G Streptococcus, protein G molecule of which interacts with three human blood serum proteins (IgG, HSA, and α2-М). However, polypeptide GM containing three IgG-binding and three HSA-bindings domains and the region binding α2-М has higher molecular mass and higher affinity to α2-М than polypeptide GM1 that includes only the α2-М binding region.

Abstract
Non-traditional model organisms are typically defined as any model the deviates from the typical laboratory animals, such as mouse, rat, and worm. These models are becoming increasingly important in human disease research, such as cancer, as they often display unusual biological features. Naked mole rats (NMRs) are currently one of the most popular non-traditional model, particularly in the longevity and cancer research fields. NMRs display an exceptionally long lifespan (~30 years), yet have been observed to display a low incidence of cancer, making them excellent candidates for understanding endogenous cancer resistance mechanisms. Over the past decade, many potential resistance mechanisms have been characterized. These include unique biological mechanisms involved in genome stability, protein stability, oxidative metabolism, and other cellular mechanisms such as cell cycle regulation and senescence. This review aims to summarize the many identified cancer resistance mechanisms to understand some of the main hypotheses that have thus far been generated. Many of these proposed mechanisms remain to be fully characterized or confirmed in vivo, giving the field a direction to grow and further understand the complex biology displayed by the NMR.

Abstract
AbstractOne method burrowing animals are hypothesized to use in adapting to the presumed hypoxic subterranean environment is increasing the oxygen-carrying capacity of blood. A number of recent studies have examined hematologic parameters in laboratory-reared naked mole-rats, but not in animals living under natural atmospheric conditions. To our knowledge, blood chemistry parameters have never been systematically assessed in a fossorial mammal. In this study we examined the blood of wild naked mole-rats in Kenya and Ethiopia to determine whether their blood chemistry differs significantly from naked mole-rats born and living in captivity. We also compared our results to published values for hystricomorphs, other subterranean rodents, and surface-dwelling rodents of similar size.

Abstract
α2-Macroglobulin is a highly abundant serum protein involved in the development of atherosclerosis and cardiac hypertrophy. However, its circulating molecular form and exact concentrations in human health/diseases are not known. Blue native-polyacrylamide gel electrophoresis of human serum was used to confirm the native conformation of α2-macroglobulin. We created an enzyme-linked immunosorbent assay suitable for quantifying its circulating molecular form and undertook a cross-sectional study to measure its serum levels in 248 patients with diabetes mellitus and 59 healthy volunteers. The predominant circulating molecular form of α2-macroglobulin was the tetramer, whereas its dimer was detectable in patients with high serum levels of α2-macroglobulin. The serum α2-macroglobulin concentration was not associated with glycated hemoglobin or any other glycemic variable as evaluated from 48-h continuous glucose monitoring, but showed close correlation with left ventricular posterior wall thickness, carotid artery intima-media thickness, urinary albumin:creatinine ratio (ACR) and brachial–ankle pulse wave velocity (baPWV). Multivariate analysis revealed only the ACR and baPWV to be independent variables influencing serum levels of α2-macroglobulin. Thus, an increased ACR and baPWV are associated with higher serum concentrations of α2-macroglobulin, and the latter may contribute to the mechanism by which albuminuria increases the risk of developing cardiovascular diseases.

Lively MJ, Westermeyer HD. In vitro assessment of the long-term stability of the inhibitory effects of canine and feline plasma on MMP 2 and 9. Vet Ophthalmol 2019; 22:898-901. [PMID: 30950143 DOI: 10.1111/vop.12668] [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: 01/22/2019] [Revised: 03/13/2019] [Accepted: 03/18/2019] [Indexed: 11/27/2022]
Abstract
PURPOSE To evaluate the effect of increasing storage time on the inhibitory effects of canine and feline plasma on matrix metalloproteinases (MMP) 2 and 9 in vitro. METHODS Matrix metalloproteinases 2 and 9 activity in the presence of canine plasma stored for 57, 155, 222, 316, 367, and 438 days, and feline plasma stored for 17, 198, 565, and 954 days was assayed using a commercially available colorimetric assay kit. RESULTS For canine plasma, the MMP 2 activity for older samples was not significantly different than the 57-day sample (P = 0.2025-0.9033). Two canine samples had significantly lower MMP 9 activity than the 57-day sample (367 days: P = 0.0099, 438 days: P = 0.0348, others P = 0.0778-0.9928). For feline plasma, storage time did not significantly affect inhibition of MMP 2 and MMP 9 activity (ANOVA, P = 0.2688 and P = 0.2404, respectively). CONCLUSIONS Increasing storage time does not significantly decrease the inhibiting activity of plasma on MMP 2 and 9 for up to 14 months in dogs and 31 months in cats.

Changes Due to Ageing in the Glycan Structure of Alpha-2-Macroglobulin and Its Reactivity with Ligands. Protein J 2019; 38:23-29.

Abstract
Alpha-2-macroglobulin (α2M) is a molecule generally associated with inflammation, and chronic inflammation is associated with ageing and cancer. The degree of inflammation was recently proposed to be considered as a biomarker of biological ageing. In this study, glycans attached to α2M were analysed in a human population of different ages by lectin-based protein microarray. Higher reactivity of α2M with several lectins was detected in older individuals indicating an increased content of specific monosaccharides: α2,6 sialic acid, mannose and N-acetylglucosamine, and multiantennary complex type N-glycans. The increased glycosylation of α2M was accompanied by reduced binding of Zn ions and insulin-like growth factor-binding protein 2 (IGFBP-2). Glycosylation of α2M and its reactivity with IGFBP-2 is similarly affected by ageing and incidence of colon cancer, but the reactivity of α2M with Zn ions is differently affected, as the binding of Zn ions remains unaltered in patients with colon cancer compared to healthy middle-aged individuals. Thus, the binding of IGFBP-2 to α2M seems to be related to structural changes in the glycan moieties of α2M, whereas binding of Zn ions, most likely, is not.

Abstract
Acute-phase protein (APPs) serum levels have been studied in many human diseases, and their components contribute to host defense during the evolution of infectious diseases by acting as part of the innate immune system. Based on the importance of establishing new experimental models, the present investigation evaluated the modulation of APPs following inflammatory stimulus by the inoculation of Aeromonas hydrophila in tilapias. Fish were sampled 6 and 24 hours post-infection. Tilapias presented increase of positive APPs such as ceruloplasmin, haptoglobin, alpha-2-macroglobulin and complement C3, as well as decrease of negative APPs such as albumin and transferrin. The protein response of tilapias during the course of bacterial infection showed correlation with the kinetics of cellular accumulation in the inflamed focus with significant increase of granulocytes, thrombocytes, lymphocytes and macrophages. However, granulocytes were the predominant cells, associated with increment in the reactive oxygen species (ROS) production. Showing responses similar to those observed in humans, the modulation of APPs and the kinetics of cellular accumulation in the exudate demonstrate the feasibility of this alternative experimental model for advances and studies to understand changes in pathophysiological mechanisms of acute inflammatory reaction due to bacterial infection.

Abstract
BACKGROUND No blood test has been shown to be effective in the prediction of primary liver cancer in patients without cirrhosis. AIM To construct and internally validate two sequential tests for early prediction of liver cancer. These tests enable an algorithm which could improve the performance of the standard surveillance protocol recommended (imaging with or without AFP), limited to patients with cirrhosis. METHODS We performed a retrospective analysis in prospectively collected specimens from an ongoing cohort. We designed an early sensitive high-risk test (LCR1) that combined (using Cox model) hepatoprotective proteins (apolipoproteinA1, haptoglobin) with known risk factors (gender, age, gammaglutamyltranspeptidase), and a marker of fibrosis (alpha2-macroglobulin). To increase the specificity, we then combined (LCR2) these components with alpha-fetoprotein. RESULTS A total of 9892 patients, 85.9% without cirrhosis, were followed up for 5.9 years [IQR: 4.3-9.4]. LCR1 and LCR2 time-dependent AUROCs were not different in construction and validation randomised subsets. Among 2027 patients with high-LCR1 then high-LCR2, 167 cancers (113 with cirrhosis, 54 without cirrhosis) were detected, that is 12 patients needed to screen one cancer. The negative predictive value was 99.5% (95% CI 99.0-99.7) in the 2026 not screened patients (11 cancers without cirrhosis) higher than the standard surveillance, which detected 113 cancers in 755 patients screened, that is seven patients needed to screen one cancer, but with a lower negative predictive value 98.0% (97.5-98.5; Z = 4.3; P < 0.001) in 3298 not screened patients (42 cancers without cirrhosis). CONCLUSIONS In patients with chronic liver disease the LCR1 and LCR2 tests identify those with a high risk of liver cancer, including in those without cirrhosis. NCT01927133.

Abstract
Cancer and ageing can be regarded as two different manifestations of the same underlying process-accumulation of cellular damage-and therefore both are closely linked. Nowadays, the ageing of populations worldwide is leading to an unprecedented increase in cancer cases and fatalities, and therefore the understanding of links between cancer and ageing is more important than ever. Spalax is considered an excellent model for ageing and, additionally, for cancer research, due to not show clear age-related phenotypic changes and not develop spontaneous tumours, despite its relatively long lifespan (∼20 years in captivity). Thereby, the purpose of this review is to summarize the recent knowledge on Spalax, with a particular emphasis on the molecular mechanisms associated with their longevity and cancer resistance.

Abstract
Cancer resistance is a major cause for longevity of the naked mole-rat. Recent liver transcriptome analysis in this animal compared to wild-derived mice revealed higher expression of alpha2-macroglobulin (A2M) and cell adhesion molecules, which contribute to the naked mole-rat’s cancer resistance. Notably, A2M is known to dramatically decrease with age in humans. We hypothesize that this might facilitate tumour development. Here we found that A2M modulates tumour cell adhesion, migration and growth by inhibition of tumour promoting signalling pathways, e.g. PI3K / AKT, SMAD and up-regulated PTEN via down-regulation of miR-21, in vitro and in tumour xenografts. A2M increases the expression of CD29 and CD44 but did not evoke EMT. Transcriptome analysis of A2M-treated tumour cells, xenografts and mouse liver demonstrated a multifaceted regulation of tumour promoting signalling pathways indicating a less tumorigenic environment mediated by A2M. By virtue of these multiple actions the naturally occurring A2M has strong potential as a novel therapeutic agent.

Abstract
The blind subterranean mole rat Spalax shows a remarkable tolerance to hypoxia, cancer-resistance and longevity. Unravelling the genomic basis of these adaptations will be important for biomedical applications. RNA-Seq gene expression data were obtained from normoxic and hypoxic Spalax and rat liver tissue. Hypoxic Spalax broadly downregulates genes from major liver function pathways. This energy-saving response is likely a crucial adaptation to low oxygen levels. In contrast, the hypoxia-sensitive rat shows massive upregulation of energy metabolism genes. Candidate genes with plausible connections to the mole rat’s phenotype, such as important key genes related to hypoxia-tolerance, DNA damage repair, tumourigenesis and ageing, are substantially higher expressed in Spalax than in rat. Comparative liver transcriptomics highlights the importance of molecular adaptations at the gene regulatory level in Spalax and pinpoints a variety of starting points for subsequent functional studies.

Abstract
The naked mole-rat (Heterocephalus glaber) is one of the most promising models used to study genome maintenance systems, including the effective repair of damage to DNA. The naked mole-rat is the longest lived rodent species, which is extraordinarily resistant to cancer and has a number of other unique phenotypic traits. For at least 80% of its lifespan, this animal shows no signs of aging or any increased likelihood of death and retains the ability to reproduce. The naked mole-rat draws the heightened attention of researchers who study the molecular basis of lengthy lifespan and cancer resistance. Despite the fact that the naked mole-rat lives under genotoxic stress conditions (oxidative, etc.), the main characteristics of its genome and proteome are a high stability and effective functioning. Replicative senescence in the somatic cells of naked mole-rats is missing, while an additional p53/pRb-dependent mechanism of early contact inhibition has been revealed in its fibroblasts, which controls cell proliferation and its mechanism of arf-dependent aging. The unique traits of phenotypic and molecular adaptations found in the naked mole-rat speak to a high stability and effective functioning of the molecular machinery that counteract damage accumulation in its genome. This review analyzes existing results in the study of the molecular basis of longevity and high cancer resistance in naked mole-rats.

Abstract
Leptospirosis is a zoonosis caused by spirochetes from the genus Leptospira. This disease is common in tropical and subtropical areas, constituting a serious public health problem. Pathogenic Leptospira have the ability to escape the human Complement System, being able to survive when in contact with normal human serum. In a previous study, our group demonstrated that supernatants of pathogenic Leptospira (SPL) inhibit the three activation pathways of the Complement System. This inhibition can be directly correlated with the activity of secreted proteases, which cleave the Complement molecules C3, Factor B (Alternative Pathway), C4 and C2 (Classical and Lectin Pathways). In this work, we analyze the activity of the leptospiral proteases on the components of Terminal Pathway of Complement, called the membrane attack complex (MAC). We observed that proteases present in SPL from different Leptospira strains were able to cleave the purified proteins C5, C6, C7, C8, and C9, while culture supernatant from non-pathogenic Leptospira strains (SNPL) had no significant proteolytic activity on these substrates. The cleavages occurred in a time-dependent and specificity manner. No cleavage was observed when we used whole serum as a source of C5-C9 proteins, probably because of the abundant presence of plasma protease inhibitors such as α2-macroglobulin. Complement protein cleavage by SPL was inhibited by 1,10-phenanthroline, indicating the involvement of metalloproteases. Furthermore, 1,10-phenanthroline- treated normal human serum diminished pathogenic leptospira survival. We also analyzed the proteolytic activity of thermolysin (LIC13322) a metalloprotease expressed exclusively by pathogenic Leptospira strains. Recombinant thermolysin was capable of cleaving the component C6, either purified or as part of the SC5b-9 complex. Furthermore, we found that the MAC proteins C6-C9 interact with thermolysin, indicating that this metalloprotease may have an additional inhibitory effect on these molecules by direct interactions. Finally, a functional assay demonstrated that thermolysin was able to inhibit MAC-dependent erythrocytes lysis. We conclude that proteases secreted exclusively by pathogenic Leptospira strains are capable of degrading several Complement effector molecules, representing potential targets for the development of new therapies and prophylactic approaches in leptospirosis.

Abstract
Ethyl pyruvate, a known ROS scavenger and anti-inflammatory drug was found to combat leukemia cells. Tumor cell killing was achieved by concerted action of necrosis/apoptosis induction, ATP depletion, and inhibition of glycolytic and para-glycolytic enzymes. Ethyl lactate was less harmful to leukemia cells but was found to arrest cell cycle in the G0/G1 phase. Both, ethyl pyruvate and ethyl lactate were identified as new inhibitors of GSK-3β. Despite the strong effect of ethyl pyruvate on leukemia cells, human cognate blood cells were only marginally affected. The data were compiled by immune blotting, flow cytometry, enzyme activity assay and gene array analysis. Our results inform new mechanisms of ethyl pyruvate-induced cell death, offering thereby a new treatment regime with a high therapeutic window for leukemic tumors.

Abstract
PURPOSE OF REVIEW Many prevalent clinical conditions, such as chronic kidney disease, diabetes mellitus, chronic obstructive pulmonary, and cardiovascular disease associate with features of premature ageing, such as muscle wasting, hypogonadism, osteoporosis, and arteriosclerosis. Studies on various animal models have shown that caloric restriction prolongs lifespan. Studies of animals with unusual long or short life for their body size may also contribute to better understanding of ageing processes. The aim of the present article is to review what we can learn about nutritional modulations and ageing interactions from animal biology. RECENT FINDINGS Caloric restriction is a powerful intervention that increases longevity in animals ranging from short-lived species, such as worms and flies, to primates. As long-term studies on caloric restriction are not feasible to conduct in humans, much interest has focused on the impact of caloric restriction mimetics, such as resveratrol, on ageing processes. Recent data from studies on the long-lived naked mole rat have provided important novel information on metabolic alterations and antioxidative defense mechanisms that characterize longevity. SUMMARY Better understanding of the biology of exceptionally long-lived animals will contribute to better understanding of ageing processes and novel interventions to extend lifespan also in humans.

Abstract
Glycosylation is the most abundant and complex protein modification, and can have a profound structural and functional effect on the conjugate. The oligosaccharide fraction is recognized to be involved in multiple biological processes, and to affect proteins physical properties, and has consequentially been labeled a critical quality attribute of biopharmaceuticals. Additionally, due to recent advances in analytical methods and analysis software, glycosylation is targeted in the search for disease biomarkers for early diagnosis and patient stratification. Biofluids such as saliva, serum or plasma are of great use in this regard, as they are easily accessible and can provide relevant glycosylation information. Thus, as the assessment of protein glycosylation is becoming a major element in clinical and biopharmaceutical research, this review aims to convey the current state of knowledge on the N-glycosylation of the major plasma glycoproteins alpha-1-acid glycoprotein, alpha-1-antitrypsin, alpha-1B-glycoprotein, alpha-2-HS-glycoprotein, alpha-2-macroglobulin, antithrombin-III, apolipoprotein B-100, apolipoprotein D, apolipoprotein F, beta-2-glycoprotein 1, ceruloplasmin, fibrinogen, immunoglobulin (Ig) A, IgG, IgM, haptoglobin, hemopexin, histidine-rich glycoprotein, kininogen-1, serotransferrin, vitronectin, and zinc-alpha-2-glycoprotein. In addition, the less abundant immunoglobulins D and E are included because of their major relevance in immunology and biopharmaceutical research. Where available, the glycosylation is described in a site-specific manner. In the discussion, we put the glycosylation of individual proteins into perspective and speculate how the individual proteins may contribute to a total plasma N-glycosylation profile determined at the released glycan level.
