Autophagy is involved in modulating tumor cell motility and invasion, resistance to epithelial-to-mesenchymal transition, anoikis, and escape from immune surveillance. We have previous shown that SAHA is capable to induce several apoptosis and autophagy-related gene expression in breast cancers. However, the exact mechanisms of autophagy activation in this context have not been fully identified. Our results showed that the expression and the activity of Cathepsin B (CTSB), one of the major lysosomal cysteine proteases, were significantly increased in MDA-MB- 231 and MCF-7 cells upon SAHA treatment...

Novel intracytoplasmic inclusions immunoreactive for phosphorylated transactivation response DNA-binding protein 43 (p-TDP43), cystatin C, and transferrin were found in anterior horn cells in a case of sporadic amyotrophic lateral sclerosis (ALS). The patient was a 59-year-old woman, who died of ALS after a clinical course of 8 years. She had been receiving mechanical support for respiration for 6 years and in a "totally locked-in" state for 4 years prior to death. The spinal cord showed severe degeneration involving the anterior and lateral funiculi, whereas the posterior funiculus was preserved...

INTRODUCTION: Acute myeloid leukemia (AML) cells show constitutive release of matrix metalloproteases and their inhibitors. We now investigated this constitutive release of protease/protease regulators associated with carcinogenesis (ADAM12, uPA, cystatin B), angiogenesis (serpin E1, uPA, CD147), cancer cell migration (uPA, cystatin C), coagulation (ADAM TS13, serpin C1), inflammation (fetuin A, caspase 1, cystatin C), monocytic differentiation (CFD) or regulation of hematopoiesis (neutrophil elastase)...

The ratio between proteases and their inhibitors is unbalanced in cancer. The cysteine protease inhibitor cystatin C is internalized by some cancer cells and affect cellular properties. Here we aimed to investigate if uptake of cystatin C and the related inhibitor cystatin E/M occur in melanoma cell lines and to evaluate to what extent the uptake affects the legumain activity that is typically increased in melanoma. First we studied the basic expression, secretion and intracellular content of all type 2 cystatins, as well as expression and activity of their possible target enzymes legumain and cathepsin B, in MDA-MB-435S, A375 and C8161 melanoma cells...

INTRODUCTION: Ibuprofen exposure results in acute transient renal dysfunction in preterm neonates, but we are unaware of data on long-term renal safety. METHODS: In a previously studied cohort of extreme low birth weight (ELBW, <1000 g) cases, the PREMATurity as predictor of children's Cardiovascular-renal Health study generated data on renal function (renal length, estimated glomerular filtration rate based on cystatin C (eGFRcysC) at the age of 11 years. This data set in 93 ELBW cases may also generate data on long-term drug safety on ibuprofen...

OBJECTIVES: Renal outcomes after critical illness are seldom assessed despite strong correlation between chronic kidney disease and survival. Outside hospital, renal dysfunction is more strongly associated with mortality when assessed by serum cystatin C than by creatinine. The relationship between creatinine and longer term mortality might be particularly weak in survivors of critical illness. DESIGN: Retrospective observational cohort study. PATIENTS: In 3,077 adult ICU survivors, we compared ICU discharge cystatin C and creatinine and their association with 1-year mortality...

In health, uromodulin is the main protein of urine. Serum uromodulin concentrations (sUMOD) have been shown to correlate with kidney function. Acute kidney injury (AKI) is among the main complications of severe acute pancreatitis (AP). No reports exist on sUMOD in patients with AP, including the diagnostic usefulness for early prediction of AP severity. We measured sUMOD during first 72 h of AP. Sixty-six adult patients with AP were recruited at the surgical ward of the District Hospital in Sucha Beskidzka, Poland...

The publication of the first tick sialome (salivary gland transcriptome) heralded a new era of research of tick protease inhibitors, which represent important constituents of the proteins secreted via tick saliva into the host. Three major groups of protease inhibitors are secreted into saliva: Kunitz inhibitors, serpins, and cystatins. Kunitz inhibitors are anti-hemostatic agents and tens of proteins with one or more Kunitz domains are known to block host coagulation and/or platelet aggregation. Serpins and cystatins are also anti-hemostatic effectors, but intriguingly, from the translational perspective, also act as pluripotent modulators of the host immune system...

BACKGROUND: African Americans develop chronic kidney disease and pulmonary hypertension (PH) at disproportionately high rates. Little is known whether PH heightens the risk of heart failure (HF) admission or mortality among chronic kidney disease patients, including patients with non-end-stage renal disease. METHODS AND RESULTS: We analyzed African Americans participants with chronic kidney disease (estimated glomerular filtration rate <60 mL/min per 1.73 m(2) or urine albumin/creatinine >30 mg/g) and available echocardiogram-derived pulmonary artery systolic pressure (PASP) from the Jackson Heart Study (N=408)...

BACKGROUND: Contrast-induced nephropathy (CIN) is a major drawback in percutaneous coronary intervention (PCI). Significant uricosuria has been reported following contrast exposure. Allopurinol-a xanthine oxidase inhibitor-has been suggested to prevent the formation of oxygen-free radicals, which may contribute to CIN. The aim of the present study was to evaluate the possible efficacy of allopurinol in preventing CIN. METHODS: In this double-blind placebo-controlled trial, patients with an estimated glomerular filtration rate ≥60 mL/min who were admitted for elective PCI, were randomized to receive either allopurinol 600 mg or a placebo administered 24 h before the procedure, and again immediately before the procedure...

Cystatin B was recently identified as an acid-resistant protein in acquired enamel pellicle; it could therefore be included in oral products to protect against caries and erosion. However, human recombinant cystatin is very expensive, and alternatives to its use are necessary. Phytocystatins are reversible inhibitors of cysteine peptidases that are found naturally in plants. In plants, they have several biological and physiological functions, such as the regulation of endogenous processes, defense against pathogens, and response to abiotic stress...

Hepatorenal Syndrome (HRS) continues to be one of the major complications of decompensated cirrhosis leading to death in the absence of liver transplantation. Challenges in precisely evaluating renal function in the patient with cirrhosis remain due to the limitations of serum creatinine (Cr) alone in estimating glomerular filtration rate (GFR); current GFR estimating models appear to underestimate renal function. Newer models incorporating renal biomarkers, such as the Cr-Cystatin C GFR Equation for Cirrhosis appear to more accurately estimate true GFR...

BACKGROUND: Serum creatinine (Scr) is the major contributing variable in glomerular filtration rate (GFR) estimating equations. Serum cystatin C (ScysC) based GFR estimating (eGFR)-equations have also been developed. The present study investigates the relation between 'rescaled' levels of these renal biomarkers (with reference interval of [0.67-1.33]) and measured GFR (mGFR). METHODS: We evaluated the diagnostic ability to detect impaired kidney function of the rescaled renal biomarkers in 8584 subjects from 12 cohorts with measured GFR, standardized Scr and ScysC...

AIMS: Pulse wave analysis (PWA) uses the technique of applanation tonometry to obtain a peripheral pulse pressure waveform from which central hemodynamic information is derived. Using PWA, subendocardial viability ratio (SEVR) can be measured. SEVR represents a noninvasive measure of myocardial perfusion. It is related to the work of the heart, the oxygen consumption, and the energy supply of the heart. Anemia is a common complication of chronic kidney disease (CKD). A complex relationship exists between CKD, cardiovascular disease (CVD), and anemia...
