BBRC These differences might be due to variation of cell types or reflect the complexity of the network involved in negative regulation of ERK activity. Thus, further dissection of the AT2 signaling pathway and identification of cross-point with Pyk2-JNK intracellular cascade, may provide new perspectives for pharmacological targeting of proliferative diseases.
Hypertension These differences might be due to a variation of cell types or might reflect the complexity of the network involved in negative regulation of ERK activity. Thus, further dissection of the AT2 signaling pathway and identification of the cross-point with EGFR cascades may provide new perspectives for pharmacological targeting of proliferative diseases and a unique example of negative cross-talk in growth signals.
BBRC However, the molecules interacting with SHP-1 were not defined in these earlier studies. Interestingly, Li et al. reported that platelet thrombin receptor causes SHP-1 tyrosine-phosphorylation in a PTX dependent manner, and suggested the role of tyrosine kinases linked to the thrombin receptor by Gi-protein.

BBRC Recently, a structural model for SHP-1 was proposed, in which SH2 domains of SHP-1 were shown to be capable of interacting with its C terminus in a phosphotyrosine-dependent manner and thereby drive the PTPase domain in an inactive conformation.

BBRC It is possible that the conformational change of SHP-1 induced by AT2 causes an increased association of SHP-1 with downstream molecules of Pyk2, leading to JNK inactivation. Thus, we speculated that AT2 has the capacity to disrupt this intramolecular interaction.

BBRC SHP-1 is predominantly expressed in hematopoietic cells and plays a key role in hematopoiesis. Although the role of SHP-1 in VSMC has not been defined in detail, the present study suggested a novel function of SHP-1 in AT2-mediated JNK inactivation followed by a growth inhibitory action.
