Abnormal function of the endocrine pancreas in genetic and experimentally induced obesity in rodents

  • Anne Beloff-Chain

Summary

Hyperinsulinaemia is a consistent feature of obesity; studies on the hyperactivity of the β-cell function of the endocrine pancreas in experimental and genetic obesity in rodents are described. Evidence that the hypersecretion of insulin may be one of the primary defects in many forms of obesity is discussed. Adrenal cortical hyperplasia and increased circulating glucocorticosteroids, as well as high pituitary ACTH levels, are among the multiple endocrine abnormalities described in the ob/ob mice.
