Following thrombin stimulation, (/sup 32/P)phosphatidic acid formation likely reflects the initial agonist-receptor interaction; therefore, these results suggest that phospholipase C activity is enhanced in platelets of SHR and that the hypersensitivity of phospholipase C in SHR may play a role in the overall alteration of cell calcium handling and, hence, in the platelet responses of SHR. 550201* - Biochemistry- Tracer Techniques, - Fed. <>stream 1B). and Hendrickson, W.A.

The phosphorylation-activated ERK1/2 translocates into the nucleus where it phosphorylates and activates MSK, p90RSK and transcription factors (e.g., c-Myc, Elk-1 and Ets-1) to stimulate cell growth and proliferation [10]. For example, a 20-second exposure to thrombin, 0.3 U/ml, induced the formation of 1.6 times more (/sup 32/P)phosphatidic acid in SHR than in WKY.
