Structure and function of somatostatin receptors in growth hormone control.

This new generation of SRIF analogs offer exciting opportunities to improve hormone hypersecretion in patients with GH- and TSH-secreting pituitary adenomas and possibly even in patients harboring prolactinomas and non-functioning tumors. Future development of novel analogs with improved affinity for both SSTR2 and SSTR5 may have even greater potency to suppress pituitary hormone hypersecretion and block adenoma growth.
