Blocking myoferlin gene can reduce breast cancer cell migration

New research suggests that a protein only recently linked to cancer has a significant effect on the risk that breast cancer will spread, and that lowering the protein's level in cell cultures and mice reduces chances for the disease to extend beyond the initial tumor.

Research discovery advances efforts to replace damaged heart muscle

In a study that began in a pair of infant siblings with a rare heart defect, Johns Hopkins researchers say they have identified a key molecular switch that regulates heart cell division and normally turns the process off around the time of birth. Their research, they report, could advance efforts to turn the process back on and regenerate heart tissue damaged by heart attacks or disease.

Researchers discover that carbohydrates serve as identifiers for cancer cells

Researchers at New York University and the University of Texas at Austin have discovered that carbohydrates serve as identifiers for cancer cells. Their findings, which appear in the journal Proceedings of the National Academy of Sciences, show how these molecules may serve as signals for cancer and explain what's going on inside these cells, pointing to new ways in which sugars function as a looking glass into the workings of their underlying structures.
