Description:

Researchers discover a new oncogene in rat cells that they call “neu.” The human version of this gene, called HER2 (and ErbB2), is overexpressed in about 20% to 25% of breast cancers (known as HER2-positive breast cancers) and is associated with more aggressive disease and a poor prognosis.
