Figure 1 Expression of peroxisome proliferator‐activated receptor γ (PPAR‐γ) in two colon cancer cells. The result was a representative of three independently performed experiments. (A) Expression of PPAR‐γ mRNA in two colon cancer cell lines. G3PDH served as an internal control. M: PBR322 DNA/MSP1 markers; line 1, 2: SW480 cells; line 3, 4: LS174T cells. (B) Expression of PPAR‐γ protein in two colon cancer cell lines. β‐actin served as an internal control. n = 3; mean (SD). **p<0.01, compared with SW480 cells.
