Application

Lanreotide acetate has been used as an inhibitor to test the plasticity of hydrogen sulfide modulation by growth hormone/thyroid hormone signaling in wild-type mice.

Biochem/physiol Actions

Lanreotide acetate is a somatostatin analog, a selective agonist for the SRIF-1 sst2 subtype of somatostatin receptor with a binding affinity of 0.8 nM for sst2 compared to 5.2 nM for sst5, 100 nM for sst3 and more than 1000 nM for the SRIF-2 subtypes, sst1 and sst4 receptors. It is used clinically in the management of acromegaly and symptoms caused by neuroendocrine tumors, and in recent studies can also inhibit tumor growth and has shown activity against non-endocrine tumors.

Somatostatin analogs (SA) are the standard of care for controlling symptoms of patients with functional gastro-entero-pancreatic neuroendocrine tumors (GEP-NETs). SA control symptoms in more than 70% of patients with carcinoid syndrome. Similar results are obtained in patients with functional, hormone-secreting

For decades, somatostatin analogs (including octreotide and lanreotide) have been indicated for relief of the symptoms of flushing, diarrhea, and wheezing associated with secretory neuroendocrine tumors (NETs). Recently, it has been suggested that somatostatin analogs may provide direct and indirect

Although neuroendocrine tumors (NETs) have been recognized as a family of complex malignancies since 1907, major progress has been made only in the past 20 years in understanding and managing the disease. The detection and reported incidence of NETs have

An antiproliferative effect of somatostatin analogs was recently demonstrated. To identify factors associated with tumor control in a group of patients with well-differentiated malignant digestive neuroendocrine tumors treated with lanreotide. A retrospective study was conducted in 68 patients treated with

Methodological shortcomings often compromise investigations into the effects of primary somatostatin-analog treatment on tumor size in acromegaly. There are also limited data for the long-acting lanreotide formulation. The aim of the study was to better characterize the effects of primary
