Irish scientists have discovered a new enzyme which plays a major role in the spread of blood cancer cells.
The researchers at NUI Galway confirmed that the find gives "significant new insights" into the development of multiple myeoloma which causes chronic fatigue, repeated infections and unexplained weight loss, among a series of debilitating ailments.
The discovery could also have implications for the way other types of tumours are treated, according to NUI Galway haematologist, Professor Michael O'Dwyer.
Details of the discovery by the NUIG team are published in the international scientific journal, Blood. It traces the over-production of the specific enzyme to the spread of the cells associated with multiple myeloma.
