The results revealed that the miR-200c overexpression in the tumors led to a marked reduction of ZEB1 mRNA (Figure 4A), Vimentin mRNA (Figure 4B) and the protein expressions (Figure 4D) compared with the CD44+CD117+CSCs with lentivirus mock and with the CD44+CD117+CSCs without lentivirus infection. This evidence concerns the gene CD44 and infection.
