MCF7 cells showed a significant increase in invasion by about 145±23% with KDM2A siRNA 1 and 118±21% with KDM2A siRNA 2 while T47D cells showed a 48±28% increase in invasion with KDM2A siRNA 1 and a 64±16% increase in invasion with KDM2A siRNA 2, demonstrating that KDM2A inhibits the invasion of breast cancer cells (Figure 2B and 2C). This evidence concerns the gene KDM2A and breast carcinoma.
