We investigated the involvement of phosphatidylinositol 3-kinase (PtdIns 3-kinase) in the initiation of signal transduction by nerve growth factor (NGF) in the rat pheochromocytoma PC12 cell line. PtdIns 3-kinase catalyzes the formation of phosphoinositides with phosphate in the D-3 position of the inositol ring and previously has been found to associate(More)
Loss of the cyclin-dependent kinase inhibitor p27(Kip1) leads to an overall increase in animal growth, pituitary tumors, and hyperplasia of hematopoietic organs, yet it is unknown whether all cells function autonomously in response to p27(Kip1) activity or whether certain cells take cues from their neighbors. In addition, there is currently no genetic(More)
A new way for reconstituting highly fusogenic Sendai virus envelopes is described. As opposed to previously described methods, in the present one the detergent (Triton X-100) is removed by direct addition of SM-2 Bio-beads to the detergent solubilized mixture of the viral phospholipids and glycoproteins, thus avoiding the long dialysis step. The vesicles(More)
