Podocyte injury is associated with progression of many renal diseases, including diabetic nephropathy. In this study we examined whether aldose reductase (AR), the enzyme implicated in diabetic complications in different tissues, is modulated by high glucose and osmolarity in podocyte cells. AR mRNA, protein expression, and activity were measured in mouse(More)
The aim of the present study was to examine the effect of 1,25(OH)2D3 (calcitriol) on SMC (smooth muscle cell) migration, especially in the context to atherogenesis. SMCs were obtained from the aortas of newborn Wistar rats by enzymatic digestion. Different aspects of cell behavior during migration in culture were examined by phase contrast, fluorescence(More)
OBJECTIVES The aim of this study was to investigate plasma concentrations of four pro-inflammatory cytokines (IL17a, IL6, TNFα and IL12p70) in patients with myocardial infarction and to analyse them according to presence of depression observed during first 6 months after myocardial infarction. METHODS In 44 patients with the first acute STEMI (ST segment(More)
A series of linear and cyclic fragments and analogs of two peptides (OGTI and HV-BBI) isolated from skin secretions of frogs were synthesized by the solid-phase method. Their inhibitory activity against several serine proteinases: bovine β-trypsin, bovine α-chymotypsin, human leukocyte elastase and cathepsin G from human neutrophils, was investigated(More)
Starting from the primary structure of sunflower trypsin inhibitor SFTI-1, we designed novel non-covalent inhibitors of human and yeast 20S proteasomes. Peptides with Arg residue in P1 position and two basic amino acid residues (Lys or/and Arg) in P2' and P3' positions strongly inhibited chymotrypsin-like and caspase-like activities, while trypsin-like(More)
