Angiotensin II human stimulates sympathetic nervous stimulation, increases aldosterone biosynthesis and renal actions. Angiotensin II human induces growth of vascular smooth muscle cells, increases collagen type I and III synthesis in fibroblasts, leading to thickening of the vascular wall and myocardium, and fibrosis. Angiotensin II human also induces apoptosis. Angiotensin II induces capillary formation from endothelial cells via the LOX-1 dependent redox-sensitive pathway.	price>

R-R-0846	(7-Diethylaminocoumarin-3-yl)carbonyl-Amyloid β-Protein (1-40)Cas .1802087-66-6	Amyloid β-protein (1-40) that is N-terminally modified with the fluorescent dye (7-diethylaminocoumarin-3-yl)carbonyl (DAC or DEAC). This derivative can be utilized to assess the binding properties of amyloid β-protein (1-40) for various membranes since it behaves very similar to the native peptide. In aqueous environments the fluorophore is almost non-fluorescent whereas binding to membranes results in an increase in fluorescence intensity (Λex = 430 nm, Λem = 470 nm). Increases in the GM1 ganglioside and cholesterol content in the lipid bilayers facilitated the binding of this peptide. For phosphatidylcholine and phosphatidylserine no affinity was observed.	price>
