Two University of Iowa researchers were part of a large multi-center study that provides compelling direct evidence of an association between prolonged residential radon exposure and lung cancer risk.
The study, an analysis of data pooled from seven different North American residential radon studies, demonstrates an 11 to 21 percent increased lung cancer risk at average residential radon concentrations of approximately 3.0 picocuries per liter of air, during an exposure period of 5 to 30 years. The lung cancer risk increased with increasing radon exposure. The U.S. Environmental Protection Agencys current action level for residential radon is 4.0 picocuries per liter.
"This analysis, based on the largest radon data set assembled in North America, agrees with a similar large-scale radon pooled analysis performed concurrently in Europe. The North American and European pooling provides unambiguous and direct evidence of an increased lung cancer risk even at residential radon exposure levels below the U.S. EPAs action level," according to R. William Field, Ph.D., UI associate professor of occupational and environmental health and epidemiology, and a co-author of the study, which is reported in the March 2005 issue of the journal Epidemiology. Charles F. Lynch, M.D., Ph.D., professor of epidemiology, also contributed to the research.

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...
