Figure 4: siRNA-induced down-regulation of DLX1 in PC3M cells has no effect on cell proliferation or migration. ( a ) Treatment with siDLX1 in PC3M cells leads to >90% reduction of DLX1 gene expression. Downregulated DLX1 does not affect ( b ) cell proliferation and ( c ) cell migration of PC3M cells. Results are representative of three individual experiments (mean ± s.d.).
