## Abstract Stimulation of postconfluent Swiss 3T3 cells in serum‐free medium with 4.3 mM Ca^2+^ results in marked increases in both released and cell‐associated plasminogen activator (PA). Increased release of PA commenced approximately 10 to 12 hours post‐stimulation and continued to increase ste
The tumor-promoting phorbol ester, 12-O-tetradecanoyl-phorbol-13-acetate, causes a rapid, partial redistribution of 1,2-diacylglycerol kinase from the cytosol to the particulate fraction of quiescent Swiss 3T3 fibroblasts. The inactive alpha form of the phorbol ester does not cause any change in dia
## Abstract The stimulation of uridine uptake, brought about by the addition of serum or insulin to quiescent 3T3 fibroblasts, is associated in the half‐saturation concentration of the uridine phosphorylating system for the substrate ATP, with relatively little change in the maximum uptake or in th
