Hedgehog Signaling Pathway Crucial for Vascular Development and Potential Therapeutic Target for Cardiovascular Disorders

Strategic Insights -

Curis, Inc., a therapeutic drug development company, announced that a report in the scientific journal Development has demonstrated the essential role of the Hedgehog signaling pathway in the formation of the blood vessels that form the vascular network throughout the body. The study, led by researchers from the University of Arizona Health Sciences Center and Harvard University, found that the Hedgehog pathway is required for the formation of the tubular structure of blood vessels in the process of angiogenesis. This process is critical for delivering oxygen and nutrients to tissues, and its dysregulation is a key factor in various cardiovascular disorders, including heart attacks and peripheral vascular disease.

Key Takeaways:

  • The Hedgehog signaling pathway is essential for the formation of blood vessels throughout the body, as demonstrated in a report published in the journal Development.
  • The pathway plays a crucial role in angiogenesis, the process of forming new blood vessels, and is required for the formation of the tubular structure of blood vessels.
  • Stimulation of angiogenesis by the Hedgehog pathway shows great promise as a therapeutic approach to promoting recovery of tissues that lack sufficient blood supply, such as occurs following heart attack or stroke.
  • The Hedgehog pathway acts by inducing multiple regeneration factors, which direct the formation of new blood vessels and prevent additional tissue damage.
  • Researchers from St. Elizabeth's Medical Center in Boston reported that injection of a gene encoding a Hedgehog protein in preclinical models of heart disease resulted in improved cardiac function and increased blood flow to the heart.
  • Myocardial ischemia, the interruption of blood flow and oxygen to heart muscle, is the leading cause of heart attacks, with more than one million cases reported every year in the United States.
  • Curis, Inc., is utilizing the biological property of the Hedgehog pathway to develop locally administered drug candidates to treat cardiovascular disorders such as heart attacks and peripheral vascular disease.
  • Lee Rubin, Curis' vice president and chief scientific officer, emphasized the potential therapeutic value of the Hedgehog pathway in promoting recovery of tissues that lack sufficient blood supply.
