Among proteins that undergo proteasomal degradation are those involved in signal transduction, metabolism regulation, cell cycle control and apoptosis. Therefore, inhibition of the ubiquitin-proteasome system check details causes inhibition of cell proliferation and induction of apoptosis, especially in cancer cells, which makes it a promising strategy of cancer therapy that is already supported by clinical trials. This article summarizes reports of known proteasome inhibitors, differing in chemical structure and mechanism of action, emphasizing their effects on
intracellular phenomena related to apoptosis and cell cycle control.”
“Maspin (SERPINB5) is a member of the Clade B subgroup of the large superfamily of serine protease inhibitors. It is proposed that maspin is
a tumor suppressor; however, its molecular role remains to be elucidated. Here we report the characterization of a mouse monoclonal antibody directed against human maspin. This antibody, 16F7, recognizes maspin in both its native and denatured form, unlike several other commercial Selumetinib supplier antibodies tested in this study. It will be a useful and versatile tool for future analyses of the biological function of maspin.”
“Objectives: The Endurant Stent Graft System (Medtronic Vascular, Santa Rosa, CA) is specifically designed to treat patients with abdominal aortic aneurysm, including those with difficult anatomies. This is the 1-year report of a prospective, non-randomised, open-label
trial at 10 European centres.
Methods: Between November 2007 and August 2008, 80 patients were enrolled for elective endovascular aneurysm repair (EVAR) with the Endurant; 71 with moderate (<= 60 degrees) and nine with high (60-75 degrees) infrarenal aortic neck angulation. Safety and stent-graft performance were assessed throughout a 1-year follow-up period.
Results: The device was successfully delivered and deployed in all cases. All-cause mortality was 5% (4/80), with one possibly device-related death. Serious adverse events were comparable between the high and moderate angulation groups. There were no device migrations, stent BTK activity inhibition fractures, aortic ruptures or conversions to open repair. Maximal aneurysm diameter decreased >5 mm in 42.7% of cases. A total of 28 endoleaks were observed (26 type II, two undetermined). Three secondary endovascular procedures were performed for outflow vessel stenosis, graft limb occlusion and iliac extension, resulting in a secondary patency rate of 100%. No re-interventions were required in the high angulation group.
Conclusions: The Endurant Stent Graft was successfully delivered and deployed in all cases and performed safely and effectively in all patients, including those with unfavourable proximal neck anatomy. (C) 2011 European Society for Vascular Surgery. Published by Elsevier Ltd. All rights reserved.
