Previously, we have demonstrated that tyrosine phosphorylation of 78 and 92 kDa proteins in rat basophilic leukemia cells (RBL-2H3) is involved in a signal transduction system for high-affinity IgE receptor (Fc epsilon RI)-mediated histamine secretion. However, it is not clarified

The mechanism for hydrogen peroxide (H2O2)-induced phospholipase D (PLD) activation was investigated in [3H]palmitic acid-labeled PC12 cells. In the presence of butanol, H2O2 caused a great accumulation of [3H]phosphatidylbutanol in a concentration- or time-dependent manner. However, treatment with H2O2 of

The role of protein tyrosine kinases (PTK) in modulating contractility has not been investigated in airway smooth muscle (ASM). We have examined the effects of the PTK inhibitors ST638, genistein, and tyrphostin A47 on contractions induced by carbachol, serotonin, ionomycin
