Increased tumor necrosis factor receptor 1 expression in human colorectal adenomas

Figure 4 Confocal laser microscopic analyses of colorectal adenoma sections. A: Tumor necrosis factor receptor 1 (TNF-R1) expression; B: Phospho-c-Jun N-terminal kinase (p-JNK) expression; C: Merged image of A and B. Co-localized expression of TNF-R1 and p-JNK was noted predominantly in the epithelial cells of adenomas. Merged images showing co-localization; D: TNF-R2 expression; E: p-JNK expression; F: Merged image of D and E. Expression of TNF-R2 was localized predominantly to the stromal area of the adenoma. Merged images showed a lack of co-localization.
