ABSTRACT
BACKGROUND:
DCLK1 is a transmembrane microtubule-associated kinase in neurons after mitotic division, which may be the intestinal cancer stem cel marker.OBJECTIVE:
To observe the expression and pathological significance of DCLK1 and Ki67 in colorectal cancer.METHODS:
Expression of Ki67 and DCLK1 in 150 cases of colorectal cancer tissues was detected by immunohistochemical method in contrast to normal colorectal mucosa, para-carcinoma tissue, and adenoma tissue. RESULTS ANDCONCLUSION:
The expression rates of DCLK1 and Ki67 were 36.7% and 34.7% in cancer tissues, respectively, both of which were significantly higher than those in normal colorectal mucosa and adenoma. The expression of DCLK1 was associated with the location, depth of invasion, lymph node metastasis (P < 0.05), while the expression of Ki67 was just associated with the depth of invasion (P < 0.05). There was a negative correlation between the expression of DCLK1 and Ki67 (r=-0.460,P=0.000). The count of DCLK1+/Ki67-cels was about 2.01% in colorectal cancer tissues, and these cels mainly distributed at the bottom of intestinal mucosa base and common duct wal. DCLK1+/Ki67- cels were oval, the nuclei were large and deep-stained with prominent nucleolus, and there was rare nuclear fission and less cytoplasm. From the aspects of cel number, location, and cel morphology, DCLK1+/Ki67- cels are in line with the characteristics of cancer stem cels; therefore, DCLK1+/Ki67-can be used as a cancer stem cel marker of colorectal cancer.
