Expression of ST13 in colorectal cancer and adjacent normal tissues

Figure 1 Expression of ST13 in normal mucosa. A: hybridization signal appeared as deep-blue granules in epithelial cells using β-actin probe as positive control; B and C: hybridization signals were seen in normal tissues using ST13 antisense probe, they were located in epithelial cells; and D: hybridization signal was not seen in negative control.

Figure 2 Expression of ST13 in colorectal cancer tissue. A and B: hybridization signals were seen in carcinoma cells using antisense probe of ST13; C: hybridization signals could not be seen using antisense probe of ST13; and D: hybridization signals could not be seen in negative control.
