a technique of transient permeabilisation has been used to show that the introduction of guanosine 5'-o- ( 3-thiotriphosphate ) ( gtp gamma s ) , a non-hydrolysable analogue of gtp , into intact swiss 3t3 fibroblasts stimulates phosphoinositide hydrolysis , cyclic amp accumulation and the activation of c-fos and c-myc proto-oncogenes .
