Abstract:

Objective

To investigate the differential expression of Stathmin and Cathepsin B in human colorectal cancer tissues and related metastatic foci and its clinicopathological significance.

Methods

Immunohistochemical staining for Stathmin and Cathepsin B was performed in 158 cases of colorectal cancer tissues and related 64 cases of metastatic foci within the tissue microarray.

Results

Both Stathmin and Cathepsin B are upregulated in colorectal cancer and related metastatic samples(P<0.05 and P<0.01 respectively). The location of Stathmin and Cathepsin B transferred from cytoplasm to nuclear in low differentiation colorectal cancer samples compared with high to mediate differentiation samples.

Conclusion

Stathmin and Cathepsin B may be valuable biomarkers for clinical differentiation of colorectal cancer.

Key words: Colorectal neoplasms, Stathmin, Cathepsin B
