Ophthalmology researchers at Washington University School of Medicine in St. Louis have identified a key risk factor for the development of cataracts. For the first time, they have demonstrated an association between loss of gel in the eyes vitreous body -- the gel that lies between the back of the lens and the retina -- and the formation of nuclear cataracts, the most common type of age-related cataracts.
The researchers reported their findings in the January issue of Investigative Ophthalmology and Visual Science.
"Most people think of cataracts as a problem that we develop if were lucky to live long enough, but clearly there are people who live to quite an old age and never get cataracts," says principal investigator David C. Beebe, Ph.D., the Janet and Bernard Becker Professor of Ophthalmology and Visual Sciences and professor of cell biology and physiology. "The perception that they are inevitable may have skewed our perspective about preventing cataracts, but it may be possible to prevent them if we can continue to home in on the causes of cataracts."

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
