Parasite inhibitors of cysteine peptidases are known to influence a vast range of processes linked to a degradation of either the parasites' own proteins or proteins native to their hosts. We characterise a novel type I cystatin (stefin) found in a sanguinivorous fish parasite Eudiplozoon nipponicum (Platyhelminthes: Monogenea). We have identified a transcript of its coding gene in the transcriptome of adult worms. Its amino acid sequence is similar to other stefins except for containing a legumain-binding domain, which is in this type of cystatins rather unusual...

Despite recent progress in the development of novel approaches to treat cancer, traditional antineoplastic drugs, such as cisplatin, remain a mainstay of regimens targeting solid tumors. Use of cisplatin is limited by acute kidney injury, which occurs in approximately 30% of patients. Current clinical measures, such as serum creatinine and estimated glomerular filtration rate, are inadequate in their ability to detect acute kidney injury, particularly when there is only a moderate degree of injury. Thus, there is an urgent need for improved diagnostic biomarkers to predict nephrotoxicity...

Multidrug-resistant (MDR) bacterial pneumonia can induce dysregulated pulmonary and systemic inflammation leading to morbidity and mortality. Antibiotics to treat MDR pathogens do not function to modulate the extent and intensity of inflammation and can have serious side effects. Herein, we evaluate the efficacy of two human cysteine proteinase inhibitors, cystatin 9 and cystatin C, as a novel immunotherapeutic treatment to combat MDR New Delhi metallo-beta-lactamase-1 (NDM-1) producing Klebsiella pneumoniae (Kp)...

REVIEW
Ayesa N Mian, George J Schwartz
Rapid, accurate, and precise measures of kidney function are essential for daily management of patients. While plasma and urinary clearances provide the greatest accuracy for assessing glomerular filtration rate (GFR), these are often impractical particularly for the care of children. Serum creatinine, the most commonly used endogenous marker, is simple, convenient, and practical but less accurate because of the influence of non-GFR determinants such as muscle mass, which increases with age in children. GFR estimating equations have been developed for adults and children to improve the accuracy of endogenous biomarkers, such as creatinine and cystatin C, by accounting for some of the non-GFR determinants, thus enhancing the practitioner's ability to assess GFR...

AIMS: While heart failure with preserved (HFpEF) and reduced ejection fraction (HFrEF) are well described, determinants and outcomes of heart failure with mid-range ejection fraction (HFmrEF) remain unclear. We sought to examine clinical and biochemical predictors of incident HFmrEF in the community. METHODS AND RESULTS: We pooled data from four community-based longitudinal cohorts, with ascertainment of new heart failure (HF) classified into HFmrEF [ejection fraction (EF) 41-49%], HFpEF (EF ≥50%), and HFrEF (EF ≤40%)...

BACKGROUND: Recent data suggest that circulating biomarkers may predict outcome in patients undergoing transcatheter aortic valve replacement (TAVR). We examined the association between inflammatory, myocardial, and renal biomarkers and their role in ventricular recovery and outcome after TAVR. METHODS AND RESULTS: A total of 112 subjects undergoing TAVR were included in the prospective registry. Plasma levels of B-type natriuretic peptide, hs-TnI (high-sensitivity troponin I), CRP (C-reactive protein), GDF-15 (growth differentiation factor 15), GAL-3 (galectin-3), and Cys-C (cystatin-C) were assessed before TAVR and in 100 sex-matched healthy controls...

IMPORTANCE: Changes in kidney function are typically followed by the sequential estimation of glomerular filtration rate (eGFR). Formulae for eGFR work well on a population basis, but there are well-known conditions where they do not work. OBJECTIVE: The purpose of this review is to summarize the existing literature on special populations in the pediatric age range and provide recommendations on how to estimate GFR in these populations. FINDINGS: The reliability of creatinine depends on muscle mass, while cystatin C (not widely available) is limited by inflammation and changes in protein catabolism...

Gastric cancer is one of the most lethal malignancies of gastrointestinal cancer and its prognosis remains dismal because of the paucity of effective therapeutic targets. Here, we show that cystatin 4 (CST4) is markedly upregulated in gastric cancer cell lines and clinical tissues. Ectopic expression of CST4 in gastric cancer cells promoted proliferation, migration, and invasion of gastric cancer cells in vitro. Furthermore, CST4 overexpression significantly promoted the tumorigenicity of gastric cancer cells in vivo, whereas silencing endogenous CST4 caused an opposite outcome...

The present study investigated the probable protective effect of vanillin (VLN) against kidney injury induced by cisplatin (CSN) and methotrexate (MTX) in rats. The rats received a single injection of either CSN (7.5 mg/kg, i.p.) or MTX (20 mg/kg, i.p.). VLN treatment (150 mg/kg/day, i.p.) was started 1 day before administration of the nephrotoxic agents and continued for 7 days. Both CSN and MTX significantly increased serum creatinine, cystatin C, and neutrophil gelatinase-associated lipocalin and kidney tissue renal malondialdehyde, inducible nitric oxide synthase, tumor necrosis factor-α, interleukin-18, nuclear factor-κB p65, cytosolic cytochrome C, and caspase-3 and significantly decreased renal total antioxidant capacity and Bcl-2/Bax ratio in rats...

BACKGROUND/AIMS: The natural polyphenol resveratrol (RSV) has been shown to ameliorate ischemia/reperfusion (I/R)-induced damage. Therefore, a rat model of I/R-induced AKI equipped with intensive monitoring was utilized to examine direct renal protection by RSV in vivo. METHODS: AKI was induced by bilateral renal clamping (45 min) followed by reperfusion (3 h). Solvent-free RSV was continuously infused intravenously (0.056 and 0.28 mg/kg) in a total volume of 7 ml/kg/h starting from 30 min before renal clamping...

Amyloid formation is associated with a number of neurodegenerative diseases that affect the independence and quality of life of aging populations. One of rather atypical, occurring at a young age amyloidosis is hereditary cystatin C amyloid angiopathy (HCCAA) related to aggregation of L68Q variant of human cystatin C (hCC). Human cystatin C plays a very important role in many aspects of human health; however, its amyloidogenic properties manifested in HCCAA present a real, lethal threat to some populations and any work on factors that can affect possible influencing hCC aggregation is not to overestimate...

BACKGROUND: Differences in cystatin C and creatinine-based estimated glomerular filtration rate (eGFR) can lead to clinical uncertainty. Existing eGFR equations perform poorly in a subset of individuals. This study aims to describe the prevalence of differences between cystatin C-based (eGFRcys) and creatinine-based (eGFRcreat) eGFR in older adults and to explore which subsets of individuals may be most affected by differing estimations. METHODS: In this cross-sectional study, participants from a cohort of community-dwelling older adults were examined at a baseline visit in 2001-2004 as part of the larger "Good Aging in Skåne" study...
