CSHL team identifies enzyme that is an important regulator of aggressive breast cancer development
Cold Spring Harbor, NY – Researchers at Cold Spring Harbor Laboratory (CSHL) have identified an enzyme that appears to be a significant regulator of breast cancer development. Called PTPN23, the enzyme is a member of a family called protein tyrosine phosphatases, or PTPs, that plays a fundamental role in switching cell signaling on and off.
When the scientists suppressed the expression of PTPN23 in human mammary cells, they noted a cascade of effects that included the cells breaking away from their anchors; their scattering; and their invasion through extracellular ...
