We show that in B-lymphocyte precursors , irradiation with gamma-rays leads to (i) stimulation of phosphatidylinositol turnover ; (ii) downstream activation by covalent modification of multiple serine-specific protein kinases , including protein kinase C ; and (iii) activation of nuclear factor kappa B .
 ( cell type: B-lymphocyte precursors, None) , ( protein: nuclear factor kappa B, None) , ( protein: serine-specific protein kinases, None) , ( protein: protein kinase C, None)
