Figure 2. Knockdown efficiency of TUG1-specific siRNA in CRC cells.
(A) qRT-PCR showing the expression of TUG1 mRNA in LoVo/si cells was significantly decreased compared with control cells (**P < 0.01); (B) qRT-PCR showing the expression of TUG1 mRNA in SW480/si cells was significantly decreased compared with control cells (**P < 0.01); (C) MTT assay showing TUG1 knock down inhibited cell proliferation of LoVo cells; (D) S TUG1 knock down inhibited cell proliferation of SW480 cells.
