Physical and functional interactions between protein tyrosine phosphatase alpha, PI 3-kinase, and PKCdelta.

The somatostatin analogue, TT-232 inhibits cell proliferation and induces apoptosis in a variety of tumor cells both in vivo and in vitro. While the early transient activation of Erk/MAPK was found to be important for the induction of cell cycle arrest, the signaling pathway leading to the activation of Erk/MAPK had not been fully established. Here we… CONTINUE READING
