PURPOSE OF REVIEW: Despite modern immunosuppression, renal allograft rejection remains a major contributor to graft loss. Novel biomarkers may help improve posttransplant outcomes through the early detection and treatment of rejection. Our objective is to provide an overview of proteomics, review recent discovery-based rejection studies, and explore innovative approaches in biomarker development. RECENT FINDINGS: Urine MMP7 was identified as a biomarker of subclinical and clinical rejection using two-dimensional liquid chromatography tandem-mass spectrometry (LC-MS/MS) and improved the overall diagnostic discrimination of urine CXCL10 : Cr alone for renal allograft inflammation...

The correlation of in vitro inhibition of cathepsin K (CatK) activity and in vivo suppression of collagen I biomarkers was examined with three selective CatK inhibitors to explore the potential translatability from animal species to human. These inhibitors exhibited good in vitro potencies toward recombinant CatK enzymes across species, with IC50 values ranging from 0.20 to 6.1 nM. In vivo studies were conducted in animal species following multiple-day dosing of the CatK inhibitors to achieve steady-state plasma drug concentration-time profiles...

BACKGROUND: Chronic kidney disease (CKD) is associated with an increased cardiovascular disease mortality risk. It is, however, less clear at what point in the course from normal kidney function to CKD the association with cardiovascular disease appears. Studying the associations of estimated glomerular filtration rate (eGFR) and albuminuria with biomarkers of (subclinical) cardiac injury in a population without substantial CKD may clarify this issue. METHODS: We examined the cross-sectional associations of eGFR and urinary albumin excretion (UAE) with high-sensitivity cardiac troponin (hs-cTn) T, hs-cTnI, and N-terminal probrain natriuretic-peptide (NT-proBNP) in 3103 individuals from a population-based diabetes-enriched cohort study...

Ageing is a complex process characterised by a systemic and progressive deterioration of biological functions. As ageing is associated with an increased prevalence of age-related chronic disorders, understanding its underlying molecular mechanisms can pave the way for therapeutic interventions and managing complications. Animal models such as mice are commonly used in ageing research as they have a shorter lifespan in comparison to humans and are also genetically close to humans. To assess the translatability of mouse ageing to human ageing, the urinary proteome in 89 wild-type (C57BL/6) mice aged between 8-96 weeks was investigated using capillary electrophoresis coupled to mass spectrometry (CE-MS)...

AIMS: To identify in the human bladder the structures which express the Beta-3 adrenoceptor (β3AR). METHODS: Human bladders from cadaveric organ donors (equally balanced in sex and age) were collected. Bladders were immediately fixed in paraformaldehyde and further processed for cryostat sectioning. Single and double immunohistochemistry was performed using antibodies against β3AR C-terminal, β3AR N-terminal, a pan-neuronal marker (β3-Tubulin) and markers of cholinergic (Vesicular Acetylcholine Transporter), adrenergic (Tyrosine Hidroxylase), and peptidergic (Calcitonin Gene-Related Peptide) nerve fibers...

: Decellularized extracellular matrix (ECM) derived from tissues and organs are emerging as important scaffold materials for regenerative medicine. Many believe that preservation of the native ECM structure during decellularization is highly desirable. However, because effective techniques to assess the structural damage in ECM are lacking, the disruptive effects of a decellularization method and the impact of the associated structural damage upon the scaffold's regenerative capacity are often debated...

A number of proteomic and peptidomic analyses of urine from diabetic subjects have been published in the quest for a biomarker that predicts progression of nephropathy. Less attention has been paid to the relationships between urinary proteins and the underlying biological processes revealed by the analyses. In this review, we focus on the biological processes identified by studying urinary proteins and protein-protein interactions at each stage of diabetic nephropathy to provide an overview of the events underlying progression of kidney disease reflected in the urine...

Studying host parasite interactions and their implications for evolution and ecology recently received increasing attention, particularly with regard to host physiology and immunity. Here we assess variation of urinary neopterin (uNEO), a marker of cellular immune activation and iummunosenescence, in response to age and anthelmintic treatment in semi-free ranging Barbary macaques (Macaca sylvanus). Urinary NEO levels were measured via enzyme-immunoassay from 179 urine samples of 43 individuals between 5-29 years of age...

BACKGROUND: The presence of white matter lesions (WML) is an indicator of small vessel disease; however, the underlying pathological mechanisms are still unclear. We aimed to investigate the association of estimated glomerular filtration rate (eGFR) and urinary albumin-to-creatinine ratio (UACR) with WML severity in first-ever stroke patients. METHODS: We retrospectively enrolled 284 consecutive patients (177 male; median age 72years) admitted to our stroke center between May 2010 and January 2012...

BACKGROUND: Hypertensive heart disease is a rising concern, especially among black South African women. As high sensitivity cardiac troponin T (cTnT) is a marker of cardiomyocyte damage, we determined the potential link of (i) systemic endothelial dysfunction (reflected by urinary albumin-to-creatinine ratio), (ii) large artery stiffness, (iii) cardiac volume load (estimated by the N-terminal prohormone B-type natriuretic peptide (Nt-proBNP)), and (iv) ECG left ventricular hypertrophy in post-menopausal black women...

: We assessed the effects of liraglutide treatment on five cardiovascular risk biomarkers, reflecting different pathophysiology: 1) Tumour necrosis factor-alpha (TNF-alpha); 2) Soluble urokinase plasminogen activator receptor (suPAR); 3) Mid-regional pro-adrenomedullin (MR-proADM); 4) Mid-regional pro-atrial natriuretic peptide (MR-proANP); and 5) Copeptin, in type 2 diabetes patients with albuminuria. In a randomised, double-blind, placebo-controlled, cross-over trial we enrolled patients with type 2 diabetes and persistent albuminuria (urinary albumin-to-creatinine ratio (UACR) > 30 mg/g) and estimated glomerular filtration rate (eGFR) ≥ 30 mL/min/1...

Case 1 : A 76-year-old man consulted a physician because of pollakisuria, decline of urinary stream. A high level of serum prostate specific antigen (PSA) was detected and he came to our hospital. He was diagnosed to have prostate cancer, cT3aN0M1b, and was treated with combined androgen blockage (CAB). Two years and nine months later, postrenal failure appeared and serum level of neuron-specific enolase (NSE) was 162 ng/ml. We performed re-biopsy of prostate, and pathological examination indicated small cell carcinoma of the prostate...

Angiotensin-(3-4) (Ang-(3-4) or Val-Tyr) is the shorter angiotensin (Ang) II-derived peptide, formed through successive hydrolysis that culminates with the release of Val-Tyr as a dipeptide. It is formed both in plasma and in kidney from Ang II and Ang III, and can be considered a component of the systemic and organ-based renin-angiotensin system. It is potently antihypertensive in humans and rats, and its concerted actions on proximal tubule cells culminate in the inhibition of fluid reabsorption, hyperosmotic urinary excretion of Na(+)...

Methane emissions from ruminal fermentation contribute significantly to total anthropological greenhouse gas (GHG) emissions. New meta-omics technologies are beginning to revolutionise our understanding of the rumen microbial community structure, metabolic potential and metabolic activity. Here we explore these developments in relation to GHG emissions. Microbial rumen community analyses based on small subunit ribosomal RNA sequence analysis are not yet predictive of methane emissions from individual animals or treatments...

Current diagnostic tests applied to inflammatory arthritis lack the necessary specificity to appropriately categorise patients. There is a need for novel approaches to classify patients with these conditions. Herein we explored whether urinary proteomic biomarkers specific for different forms of arthritis (rheumatoid arthritis (RA), psoriatic arthritis (PsA), osteoarthritis (OA)) or chronic inflammatory conditions (inflammatory bowel disease (IBD)) can be identified. Fifty subjects per group with RA, PsA, OA or IBD and 50 healthy controls were included in the study...

BACKGROUND: Olmesartan and azilsartan, angiotensin II receptor blockers (ARBs), are expected to decrease blood pressure more than the other ARBs. We conducted randomized-controlled trials to compare the practical efficacy of olmesartan with azilsartan. METHODS: Eighty-four patients treated with the conventional ARBs for more than 3 months were assigned randomly to receive either 20 mg of olmesartan (olmesartan medoxomil, OL group) or 20 mg of azilsartan (azilsartan, not azilsartan medoxomil, AZ group) once daily for 16 weeks...

: Defensins are small anti-microbial peptides capable of neutralizing human adenovirus (HAdV) in vitro by binding capsid proteins and blocking endosomal escape of virus. In humans, the alpha defensin HD5 is produced by specialized epithelial cells of the gastro-intestinal and genito-urinary tracts. Here we demonstrate that HD5 is also expressed as an active, secreted peptide by epithelial ovarian and lung cancer cells in situ, in patient biopsies. This finding triggered us to study the role of HD5 in infection and spread of replication-competent, oncolytic HAdV type 3 virus...
