AIM: To detect the expression of huCdc7 in colorectal cancer.
METHODS: The mRNA and protein expression of huCdc7 in 39 colorectal cancer tissue specimens and matched tumor-adjacent normal colorectal tissue specimens was detected by reverse transcription-polymerase chain reaction and immunohistochemistry, respectively.
RESULTS: The relative expression level of huCdc7 mRNA in colorectal cancer was significantly higher than that in tumor-adjacent normal colorectal tissues (0.03675 ± 1.00 vs 0.01199 ± 0.44, P < 0.05). huCdc7-positive cells displayed brown granules in the nucleus. Tumor tissues contained many huCdc7-positive cells, whereas normal colorectal tissues contained very few positive cells.
CONCLUSION: huCdc7 may play an important role in the development and progression of colorectal cancer.
Core tip: huCdc7 is ubiquitously expressed in human tissues and can regulate DNA replication initiation. Abnormal expression or excessive activation of huCdc7 can promote excessive cell proliferation and cause tumorigenesis. Colorectal cancer is a common digestive tract tumor with a gradually increasing incidence. We found that huCdc7 may play an important role in the development and progression of colorectal cancer.
