A stroke drug known as tPA, or tissue plasminogen activator, has been a lightning rod since it was first approved in the United States in 1996. Although studies have found that the drug can reduce the brain damage wrought by strokes, it can also cause potentially fatal bouts of cerebral bleeding. Now a team of researchers has identified one reason for tPA's ill effect. And it turns out that in mice, the problem can be eased by administering a cancer drug.

Recent studies have revealed that a glycolytic enzyme, enolase (ENO), is involved in many different physiological and pathophysiological conditions. ENO can be detected in many prokaryotic and eukaryotic cells, and is localized in cytoplasm, cell surface and nucleus of various mammalian cells to possibly mediate distinct functions. The surface ENO acts as a plasminogen-binding receptor. Upon cleavage by plasminogen activator, plasminogen is converted to plasmin that can activate collagenase and degrade fibrin and several extracellular matrix proteins
