A Potential Inhibitory Role for the New Truncated Variant of Somatostatin Receptor 5, sst5TMD4, in Pituitary Adenomas Poorly Responsive to Somatostatin Analogs

Abstract

These results indicate that sst5TMD4 is related to the reduced ability of octreotide at normalizing hormone secretion in poorly responsive tumors in vivo. Further studies will help to evaluate the potential use of sst5TMD4 expression in surgically removed pituitary adenomas as a predictor of the subsequent response of different pituitary tumors to SSA therapy.
