Figure 2. AIM2 protein expression in human CRC cell lines. (A) Western blots of AIM2 protein in five human CRC cell lines (HCT116, CCL244, SW480, SW620 and LoVo). GAPDH as a loading control. (B) Western blots of AIM2 protein in SW480 and SW620 cells stably transfected with control-shRNA (NC) or shRNA against AIM2 (KD). GAPDH as a loading control. Each experiment was performed at least triplicate and the bands were quantified and presented as the mean±SEM. (C) Western blots of AIM2 protein in HCT116 and LoVo cells stably transfected with empty vector (VEC) or plasmid encoding human AIM2 (AIM2). GAPDH as a loading control. Each experiment was performed at least triplicate and the bands were quantified and presented as the mean±SEM. **P<0.01, based on a two-tailed paired Student’s t-test.
