a Volcano plots displaying the expression of probe sets in MCF-7/Twist, primary tumors, and metastatic tumors compared to parental MCF-7 cells. Bold line at y = 1.3 corresponds to log10 value of significance (P = 0.05). Significantly up-regulated probe sets are colored red while significantly down-regulated probe sets are indicated in green b Scatter plots displaying the correlation between probe sets of various class comparisons - MCF-7/Twist, primary tumors, and metastatic tumors
