Growth hormone and insulin-like growth factor I: nutritional pathophysiology and therapeutic potential

Abstract

The growth hormone--insulin-like growth factor I axis has been appreciated for more than 30 years and the effects of malnutrition on this axis for more than 20 years. Over the last decade, advances in molecular biology have permitted enhanced understanding of feedback regulation between growth hormone and IGF-I at the gene level, including limited information on nutritional influences. Similarly, the availability of recombinant human growth hormone has allowed controlled clinical studies demonstrating its net anabolic actions at hypocaloric dietary energy intake levels and its ability to enhance height velocity in children with various causes of diminished growth. Although investigational use of recombinant IGF-I in humans has been limited, its actions are likely to complement those of growth hormone during periods of profound dietary energy deficit. From the information presented, two hypotheses are developed. First, recombinant IGF-I administration will enhance substrate anabolic events during the acutely malnourished state when dietary intake is severely limited. Second, administration of recombinant human growth hormone will accelerate protein anabolism and catch-up growth during the period of recovery from protein-energy m...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

LRRK2 & Immunity During Infection

Mutations in the LRRK2 gene are a risk-factor for developing Parkinson’s disease. However, LRRK2 has been shown to function as a central regulator of vesicular trafficking, infection, immunity, and inflammation. Here is the latest research on the role of this kinase on immunity during infection.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

Meningococcal Myelitis

Meningococcal myelitis is characterized by inflammation and myelin damage to the meninges and spinal cord. Discover the latest research on meningococcal myelitis here.

Alzheimer's Disease: MS4A

Variants within membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease by recent genome-wide association studies. Here is the latest research.
