The pancreas, Stomach & Upper intestine. It is a Hormone.
Delta cells, also known as D cells, are responsible for producing somatostatin in the pancreas. Somatostatin is a hormone that inhibits the secretion of other hormones, such as insulin and glucagon, and has various functions in the body including regulating digestion and inhibiting the release of growth hormone.
Pancreas produces insulin hormone to lower sugar in blood.
The pancreas is endocrine (producing several important hormones, including insulin, glucagon, and somatostatin). The most important is insulin which controls the take-up of glucose by the body's cells.
Somatostatin is 14 amino-acid and is water soluble and polar.Here is a good page with informationhttp://www.answers.com/somatostatin
Somatostatin
Somatostatin is not produced by the acini of the pancreas. It is primarily produced by delta cells in the pancreatic islets (islets of Langerhans) and acts as an inhibitor of many gastrointestinal functions, including the secretion of insulin and glucagon.
Somatostatin
Several hormones are secreted by the pancreas. They include insulin, glucagon, somatostatin, and pancreatic peptide.
D-cells, or Delta cells, can be found in the stomach, intestine, or Islets of Langerhans (the hormone producing regions of the pancreas which also produce glucagon and insulin). Delta cells produce somatostatin, a regulatory hormone. When somatostatin is released it interacts with specialized receptor cells, these cells control the production of other hormones. Somatostatin coming in contact with a somatostatin receptor will inhibit the production of hormones that receptor controls.
The liver produces bile to break down fats, and filter toxins. The pancreas creates vital enzymes such as amylase. 8======D
Hormone-secreting tumors can be successfully treated with surgery, radiation, bromocriptine (Parlodel), Sandostatin (Octreotide), or other somatostatin analogues (drugs similar to somatostatin).
