Enhancement of granulocyte-endothelial cell adherence and granulocyte-induced cytotoxicity by platelet release products.

abstract：:Mutations in genes that encode components of the phosphatidyl-inositol 3-kinase (PI3-kinase) signaling pathway are common in human cancer. The recent discovery of nonrandom somatic mutations in the PIK3CA gene of many human tumors suggests an oncogenic role for the mutated enzyme. We have determined the growth-regulat...
