Aberrant expression of ether à go-go potassium channel in colorectal cancer patients and cell lines

Figure 1 Typical immunohistochemical staining for Eag1 in colorectal cancer and adenoma. A, B, C: Positive staining of colorectal cancers; D: Positive staining of metastasis tissue from greater omentum; E: Negative control of colorectal cancer; F: Positive staining from one case of colonic adenoma.

Figure 2 Eag1 mRNA expression in colorectal cancer and adenoma. Eag1 mRNA positively expressed in LoVo and HT29 cell lines and in 10/13 of colorectal cancer tissues, but negatively expressed in NCMT( not shown) and colorectal adenoma. M, molecular weight marker; 0, water.
