This hypothesis was confirmed by Q-PCR which showed a significantly increased expression of twist1, (fold change 4,99 in KBr1 and 2,16 in KBr2) and snail1 (fold change 7,55 in KBR1 and 4,46 in KBr2) in both breast cancer samples, showing higher migratory activity after co-culture with ASCs (Figure 2B). This evidence concerns the gene SNAI1 and breast carcinoma.
