Expression of NF-κB and human telomerase reverse transcriptase in gastric cancer and precancerous lesions

Figure 1 Immunohistochemical detection of NF-κBp65 protein in gastric carcinoma showing cytoplasmic and nuclear staining SP×400.

Figure 2 Immunohistochemical detection of hTERT protein in poorly differentiated gastric carcinoma. A positive reaction was shown in the nuclei of cancer cells. SP×400.

Figure 3 Detection of hTERT mRNA in a mucinous adenocarcinoma. Most tumor cells displayed strong signals that were localized in the cytoplasm. ISH×400.

Figure 4 Detection of hTERT mRNA in intestinal metaplasia. The reaction was localized in the cytoplasm of intestinal meta-plastic cells, activated lymphocytes, as well as replicating cells in basal layer, while the surface epithelia were negative. ISH×100.
