SSTR2 and neoplasm: In mice separately xenografted with control cells on one flank and SSTR2 expressing cells on the other flank, an anti-tumor effect was induced: the growth of control tumors (in animals that also received SSTR2 expressing cells) was delayed by 33 days and was associated with decreased and increased indices of proliferation and apoptosis, respectively, when compared with control tumors that grew alone.
