Johns Hopkins Kimmel Cancer Center researchers are studying whether delivering chemotherapy drugs directly to breast "plumbing" might make treatment of early breast cancer easier on the patient and at least as good as surgery or radiation.
A report on successful tests of intraductal therapy in rats and mice published in the January 15 issue of Cancer Research has paved the way for one of the first preliminary clinical trials in women with breast cancer, currently under way in women with breast cancer scheduled for a mastectomy at Johns Hopkins.
For more than a decade, researchers have been studying how to diagnose breast cancer earlier by extracting fluid from the vast network of tiny milking-producing ducts in the breast. The idea is based on the finding that most breast cancers sprout from cells lining the milk ducts. This same idea led Kimmel Cancer Center researcher Saraswati Sukumar, Ph.D., to explore the possibility of treating early breast cancers by using hair-thin catheters to inject chemotherapy through openings at the nipple directly into the place where they started - the milk ducts.
Sukumar likens the procedure to pouring detergent down the kitchen sink to rid the pipes of unwanted material. Because early breast cancers are less likely to have escaped the ducts, intraductal therapy may have at least as good a chance to cure as radiation or surgery.

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...
