Skeletal Diseases

SKELETAL DISEASES

Skeletal diseases are a diverse and often debilitating group of conditions that affect the bones. They include a broad range of disorders, such as:

• Sarcomas, which are cancers that begin in the bone and connective tissues. There are many different types of sarcomas; some, like Ewing sarcoma, almost exclusively affect children.
• Bone metastases, which are cancers spread to the skeleton from another part of the body, such as the breast or prostate. Once in the bone, these cancers become much more difficult to treat.
• Osteoarthritis, a common degenerative joint disease caused by the breakdown of cartilage, a shock-absorber-like tissue between the bones. More than 30 million people in the U.S. have osteoarthritis.
• Osteoporosis, a disease that causes the bones to become porous and weak, resulting in painful breaks that may be caused by something as simple as a sneeze or gentle bump.
• Skeletal dysplasias, a group of more than 300 conditions that negatively affect bone and joint development and cause lifelong problems for patients.

These conditions can be extremely painful and cause loss of mobility, which significantly reduces quality of life. While some treatments do exist for these diseases, more research is needed to find new prevention strategies and improved therapies.

What we’re doing

Scientists in Van Andel Institute’s (VAI) Center for Cancer and Cell Biology study the full spectrum of bone biology, from the mechanisms that give rise to healthy bone tissue to those that cause disease. They work to translate their findings into new strategies to combat these often tough-to-treat conditions by:

• Understanding the basics: VAI scientists are studying the differences between healthy and abnormal bone to pinpoint how skeletal diseases arise and how they can be treated.
• Searching for new cancer treatments: VAI scientists are studying cancers that originate in the bone in an effort to better combat these painful and challenging malignancies.
• Investigating ways to beat bone metastases: Understanding why some cancers — such as those that start in the breast, prostate and lung — are highly predisposed to spread and grow in the skeleton will help scientists develop better therapies that enhance the quality of life for patients.
• Exploring the causes of osteoarthritis and osteoporosis: Both of these diseases contribute significantly to loss of mobility and quality of life. A precise understanding of the mechanisms that lead to their onset will give scientists powerful new tools for prediction, prevention and treatment.
