KAI1 gene expression in colonic carcinoma and its clinical significances

Figure 1 In situ hybridization detection of expression of KAI1 mRNA in colorectal carcinoma cell lines (Original magnification: × 400). A: In HT29 cells, the positive expression (brown granule) was located in cytoplasm; B: In SW480 cells, the positive expression was located in cytoplasm; C: In SW620 cells, the expression of KAI1 mRNA was negative; D: In LoVo cells, the expression of KAI1 mRNA was negative.

Figure 2 Expression of KAI1 protein detected by immunohistochemistry in colorectal carcinoma cell lines (Original magnification: × 400). A: In HT29 cells, the positive expression located in cytoplasm and membrane; B: In SW480 cells, the positive expression located in cytoplasm and membrane.

Figure 3 In situ hybridization and immunohistochemical detection of KAI1 mRNA and protein in colonic carcinoma (Original magnification: × 400). A: In situ hybridization detection found that strong KAI1 mRNA staining was located in cytoplasm (brown granule); B: Detection by immunohistochemistry showed strong KAI1 protein staining was in cytoplasm and membrane.
