Abstract
Metastasis is a major cause of breast cancer mortality and the current study found histone demethylase, KDM2A, expression to be negatively correlated with breast cancer metastasis. KDM2A knockdown greatly promoted migration and invasion of breast cancer cells. The histone demethylase activity of KDM2A downregulated EGF transcription and suppressed the EGF-TSPAN8 pathway. Inhibition of breast cancer cell migration was also dependent on the histone demethylase activity of KDM2A. A novel mechanism of KDM2A-suppression of the EGF-TSPAN8 pathway which inhibited breast cancer cell migration and invasion is reported.
