Researchers at the University of Missouri have unraveled how a cancer-critical enzyme is positioned on cell surfaces. The enzyme enables tumor cells to tunnel through collagen, creating a convenient path for tumors to spread ...

Since Carnegie Institution's Barbara McClintock received her Nobel Prize on her discovery of jumping genes in 1983, we have learned that almost half of our DNA is made up of jumping genes—called transposons. Given their ...

DNA-damaging agents, or "DDAs," make up the most widely used group of cancer drugs. Yet their therapeutic success has been curtailed by drug resistance—either present in cancer cells from the disease onset or arising during ...

If we really want to know how our body's cells work—or don't work, in the case of disease—we might need to look beyond their genes and even beyond the proteins they are made of. We may need to start going through the ...
