Talcum powder stunts growth of lung tumors
..., slows cell growth and movement, and even induces nearby tumor cells to commit suicide. All of these make it hard for tumors to grow and spread into healthy lung tissue. When endostatin was first discovered in 1997, doctors hoped its tumor-fighting properties would lead to a cure for cancer. But clinical......m added chemicals to normal human cells that force nearby proteins together into a clump, and this was enough to get them sent out of the cell in exosomes. If they added a tether to force naturally-clumping proteins inside the cell to the membrane, the proteins met a similar exosomal deportation fate. Th...Fire ants are emerging nuisance for Virginians
