How heavy a man is at the time he is diagnosed with prostate cancer, as well as his history of weight gain, appear to play significant roles in how aggressive his cancer may become, say researchers at The University of Texas M. D. Anderson Cancer Center.
While a link between weight and initial development of prostate cancer already has been made, this report, published in the Oct. 1 issue of Clinical Cancer Research, is the first to associate a mans body mass at different ages and adult weight gain with the risk of progression after his prostate cancer has been surgically treated.
"These findings support the view that the development of aggressive forms of prostate cancer may be influenced by environmental effects that occur early in life," says the studys lead researcher Sara Strom, Ph.D., an associate professor in the Department of Epidemiology.
Strom says that it is currently unclear how excess obesity contributes to prostate cancer progression, although leading theories suggest it could be linked to changes in a number of different hormones (such as androgen and growth factors) and/or lifestyle behaviors (such as poor diet and inadequate physical activity). But she adds that "understanding the mechanisms by which weight gain contributes to prostate cancer progression will lead to rationally designed preventive strategies."

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...
