ABSTRACT
<p><b>OBJECTIVE</b>To study the possible role of JNK1, Raf-1 and Livin in the carcinogenesis of sporadic colorectal tubular adenoma.</p><p><b>METHODS</b>Immunohistochemical staining was used to detect the expression of JNK1, Raf-1 and Livin proteins in 65 sporadic colorectal tubular adenomas with dysplasia of varying degrees and 22 colorectal tubular adenoma with cancerous area.</p><p><b>RESULTS</b>In normal colorectal mucosa, colorectal tubular adenoma with dysplasia and colorectal tubular adenoma with cancerous area, the positive rate of JNK1, Raf-1 and Livin expression was increased gradually. The positive expression of JNK1, Raf-1 and Livin was all significantly higher in the cases of colorectal tubular adenoma with dysplasia or with cancerous area than that in normal colorectal mucosa (P < 0.05), and the positive expression of JNK1, Raf-1 and Livin was significantly higher in colorectal tubular adenoma with cancerous area than that in colorectal tubular adenoma with dysplasia of different degrees (P < 0.05). In the cases of colorectal tubular adenoma with dysplasia of varying degrees, the positive expression of Raf-1 was increased along with the increasing dysplasia degree of colorectal tubular adenoma (P < 0.05). Coexpression of JNK1, Raf-1 and Livin increased gradually in the carcinogenesis of sporadic colorectal tubular adenoma, while positive correlation was found among the expressions of JNK1, Raf-1 and Livin.</p><p><b>CONCLUSION</b>JNK1, Raf-1 and Livin may be involved in the carcinogenesis of sporadic colorectal tubular adenoma.</p>
