Insulin signal transduction pathway is secreted after glucose enters the beta cell and that triggers several other processes in a chain reaction. While insulin is secreted by the pancreas to lower blood glucose levels, glucagon is secreted to raise blood glucose levels. This is why glucagon has been known for decades as a counter-regulatory hormone. When blood glucose levels are low, the pancreas secretes glucagon, which in turn causes the liver to convert stored glycogen polymers into glucose monomers, which is then released into the blood. This process is called glycogenolysis. Liver cells, or hepatocytes, have glucagon receptors which allow for glucagon to attach
Adrenocortical hormone an adrenal tumor or by hypersecretion of adrenocorticotropic hormone (ACTH) from the anterior pituitary gland. It is predominantly due to an excess of the glucocorticoid cortisol. Secretion is typically regulated by the hypothalamus which secretes corticotropin-releasing hormone (CRH) to the pituitary gland, stimulating the pituitary to secrete adrenocorticotropic hormone (ACTH). ACTH then travels to the adrenal glands and induces the release of cortisol into the bloodstream. In Cushing’s syndrome, this process occurs in excess. Some symptoms of an individual with Cushing’s syndrome include low tissue protein levels, due to muscle and bone atrophy, and high blood glucose levels. Sodium levels
