Calcium ions play a critical role in neurotransmitter release. The cytosolic Ca2+ concentration ([Ca2+]cyt) at nerve terminals must therefore be carefully controlled. Several different mechanisms, including a plasmalemmal Na/Ca exchanger, are involved in regulating [Ca2+]cyt. We employed immunofluorescence microscopy with polyclonal antiserum raised against(More)
The formation of a microvascular endothelium plays a critical role in the growth and metastasis of established tumors. The ability of a fragment from the first type III repeat of fibronectin (III(1C)), anastellin, to suppress tumor growth and metastasis in vivo has been reported to be related to its antiangiogenic properties, however, the mechanism of(More)
BACKGROUND Endostatin and anastellin, fragments of collagen type XVIII and fibronectin, respectively, belong to a family of endogenous inhibitors of angiogenesis which inhibit tumor growth and metastasis in a number of mouse models of human cancer. The mechanism of action of these inhibitors is not well understood, but they have great potential usefulness(More)
