Crk-associated substrate (Cas) lymphocyte-type (Cas-L) is a 105-kDa cytoplasmic protein consisting of Src homology-3 domain and multiple YXXP motifs (substrate domain). Our previous studies showed that Cas-L is tyrosine-phosphorylated following the ligation of TCR and beta 1 integrins in T lymphocytes. Here we show that Cas-L is involved in T cell motility following the ligation of TCR and beta...

OBJECTIVES The main purpose of this study was to investigate whether carotid artery stenting (CAS) plus medicine in patients with severe carotid artery stenosis provide a better long-term blood pressure (BP) control compared to other medical treatments alone. The other aim was to explore the correlation between post-CAS hypotension within 6 h and long-term BP reductions after CAS. MATERIALS A...

Resistance to chemotherapy remains a major obstacle for the treatment of breast cancer. Understanding the molecular mechanism(s) of resistance is crucial for the development of new effective therapies to treat this disease. This study examines the putative role of p130(Cas) (Cas) in resistance to the cytotoxic agent Adriamycin. High expression of Cas in primary breast tumors is associated with ...

Résumé Le puisatier a pour profession le creusement et l'entretien des puits pour fournir de l'eau. Il est au contact de divers minerais, particulièrement la silice, particule qui présente un risque certain de développement des maladies pulmonaires connues sous le nom de silicose. Le but de notre travail est de préciser le profil épidémiologique, clinique, radiologique et évolutif des patients ...

BACKGROUND Coronary artery ectasia (CAE) is a localized or diffuse abnormal dilatation of coronary arteries. Controversy still remains about its cardiovascular events rate, prognosis, and etiology. Adverse effects of CAE coinciding with coronary artery stenosis (CAS) (and in isolated form) are unclear. OBJECTIVES We aimed to investigate the cardiovascular event rate of CAE in comparison to 'C...

This paper describes the cunning ant system (cAS), which can be used to optimize problems with candidate solutions represented by permutations. cAS generates new candidate solutions from a combination of the pheromone density and the archive of past candidate solutions. Performance of cAS is demonstrated on two important classes of permutation problems: (1) the traveling salesman problem and (2...

UNLABELLED Bacteria and archaea face continual onslaughts of rapidly diversifying viruses and plasmids. Many prokaryotes maintain adaptive immune systems known as clustered regularly interspaced short palindromic repeats (CRISPR) and CRISPR-associated genes (Cas). CRISPR-Cas systems are genomic sensors that serially acquire viral and plasmid DNA fragments (spacers) that are utilized to target a...

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...

Background—Carotid artery stenting (CAS) and carotid endarterectomy (CEA) are alternative strategies for stroke prevention in patients with atherosclerotic carotid disease. Although randomized clinical trials are the gold standard for assessing the relative benefits of different treatments, observational research is necessary for determining “real-world” effectiveness. Current recommendations l...
