What causes bone loss in elderly 

Researchers have identified a mechanism that leads to bone loss in older adults, an advance that may help develop therapeutics to treat the age-associated bone loss condition.

According to Study:

• Osteoporosis,the thinning of bone and the loss of bone density that increases the risk of fractures is a major health problem in older people.
• Often the condition is accompanied by an increase in fat cells in the bone marrow.
• The study found a protein called Cbf-beta which plays a critical role in maintaining the bone-producing cells.
• Furthermore, the examination of aged mice.
• Showed dramatically reduced levels of Cbf-beta in bone marrow cells as compared to younger mice.
• The findings showed when this mechanism malfunctions, progenitor cells stop creating bone-producing cells and instead create fat cells.
• Thus, maintaining this Cbf-beta may be essential to prevent human age-associated osteoporosis that is due to elevated creation of fat cells.

Results:

• Knowledge of this mechanism can provide targets in the search for novel bone-loss therapeutics.
• To treat human osteoporosis with minimal side effects, the researchers noted.
