This study was aimed at seeking more information concerning the role and site of action of the protein tyrosine kinases and phosphatases, and to identify any cross talk between their pathways and other systems. This was achieved with the use of pharmacological inhibitors applied in experiments, which measured physiological cell responsiveness. Description: M.PHIL. 1999-01-01T00:00:00Z
