Insulin is a hormonal protein consisting of two chains of 21 and 30 amino acids. Insulin acts on neurons and glial cells to regulate systemic glucose metabolism and feeding. Insulins(cattle) is a type of native insulins. Insulins(cattle) was used to treat patients presenting with diabetes mellitus[1].
Insulin signaling is initiated by binding of insulin to the insulin receptor, activation of the protein tyrosine kinase domain and tyrosine autophosphorylation of the insulin receptor, and extensive tyrosine phosphorylation of insulin receptor substrate (IRS) proteins, and phosphorylation of S473 in AKT[2]
Injected mice with insulin (i.v., 0.5 IU/ kg−1 body weight) and assessed phosphorylated AKT (pAKT) immunoreactivity in tanycytes. These analyses revealed that insulin treatment robustly induced AKT phosphorylation in tanycytes of control mice, and that this activation was largely diminished in tanycytes of IR∆Tan mice(mice lacking insulin receptors in tanycytes)[3]
