BACKGROUND Comprehensive analysis of proteome differentially expressed in response to surgery or drug treatment is useful to understand biological responses to dispensed interventions. Here we investigated expression changes in sera of patients who suffered from calcific aortic stenosis (CAS), before and after surgery for aortic valve replacement. MATERIALS AND METHODS Sera obtained before an...
Cell migration requires the cyclical assembly and disassembly of focal adhesions. Adhesion induces phosphorylation of focal adhesion proteins, including Cas (Crk-associated substrate/p130Cas/BCAR1). However, Cas phosphorylation stimulates adhesion turnover. This raises the question of how adhesion assembly occurs against opposition from phospho-Cas. Here we show that suppressor of cytokine sign...
Assembly of contractile apparatuses in striated muscle requires precisely regulated reorganization of the actin cytoskeletal proteins into sarcomeric organization. Regulation of actin filament dynamics is one of the essential processes of myofibril assembly, but the mechanism of actin regulation in striated muscle is not clearly understood. Actin depolymerizing factor (ADF)/cofilin is a key enh...
Crk-associated substrate (CAS, p130Cas) is a major tyrosine phosphorylated protein in cells transformed by v-crk and v-src oncogenes. We recently reported that reexpression of CAS in CAS-deficient mouse embryo fibroblasts transformed by oncogenic Src promoted an invasive phenotype associated with enhanced cell migration through Matrigel, organization of actin into large podosome ring and belt s...
Adhesive interactions between cells and extracellular matrix proteins play a vital role in biological processes such as cell proliferation, differentiation and survival. Integrins comprise a major family of cell surface receptors that mediate these interactions. Integrin engagement triggers adhesiondependent intracellular signalling cascades that include the phosphorylation of tyrosines in intr...
Six years ago a new sophisticated prokaryotic defense system was identified that was termed CRISPR-Cas (CRISPR, clustered regularly interspaced short palindromic repeats; Cas, CRISPR associated). Parts of it, the mysterious repeat sequences, were already detected in 1987 but their function remained unknown for the next 20 y. The CRISPR-Cas system is an adaptive, heritable defense system that pr...
BACKGROUND AND PURPOSE Beta adrenergic overstimulation may increase the vascular damage and stroke. However, the underlying mechanisms of beta adrenergic overstimulation in cerebrovascular dysfunctions are not well known. We investigated the possible cerebrovascular dysfunction response to isoproterenol induced beta-adrenergic overstimulation (ISO) in rabbit cerebral arteries (CAs). METHODS I...
CRISPR (clustered regularly interspaced short palindromic repeats) arrays and Cas (CRISPR-associated) proteins confer acquired resistance against mobile genetic elements in a wide range of bacteria and archaea. The phytopathogen Pectobacterium atrosepticum SCRI1043 encodes a single subtype I-F CRISPR system, which is composed of three CRISPR arrays and the cas operon encoding Cas1, Cas3 (a Cas2...
Small RNAs target invaders for silencing in the CRISPR-Cas pathways that protect bacteria and archaea from viruses and plasmids. The CRISPR RNAs (crRNAs) contain sequence elements acquired from invaders that guide CRISPR-associated (Cas) proteins back to the complementary invading DNA or RNA. Here, we have analyzed essential features of the crRNAs associated with the Cas RAMP module (Cmr) effec...
