IGF-1

IGF-1, or Insulin-like Growth Factor 1, is a hormone that plays a crucial role in growth and metabolism, influencing various health conditions from cardiovascular disease to cancer. Studies have linked IGF-1 levels with an increased risk of cardiovascular issues; higher IGF-1 levels are associated with adverse outcomes in heart health. In colorectal cancer, the signaling pathway involving IGF-1 has been found to impact glucose metabolism, potentially aiding tumor growth. Additionally, IGF-1 is involved in inflammatory conditions like cachexia and certain viral infections, where it can influence disease progression. Its role extends to hair loss, as part of a pathway that contributes to male pattern baldness, and it also plays a part in the development of polycystic kidney disease through interactions with metalloproteinases.

IGF-1 is closely connected to growth hormone, which stimulates its production, and to IGFBP-3, a binding protein that modulates IGF-1 activity. These connections highlight the complex interplay between growth factors and their regulators in health and disease. While these studies provide insights into IGF-1's diverse roles, more research is needed to fully understand its implications for clinical practice and treatment strategies.
