BACKGROUND: Early metastases is still unresolved problem in cancer management, eventually in colorectal cancer (CRC). In addition, many markers are useful just only in the late stage of CRC.AIM: This study evaluates the differences in the expression intensity of nuclear β-catenin, cytoplasmic β-catenin, E-cadherin, and N-cadherin between CRC SW480 cell line as control group and COLO320DM and HCT116 cell lines as case groups.MATERIALS AND METHODS: This study applied experimental research design with the different test methods. Culture growing and subcultures manufacturing for the CRC cell line models were done initially and followed by the immunofluorescence method by administering antibodies on β-catenin, E-cadherin, and N-cadherin, and continued with staining process using fluorescein-5-isothiocyanate and 4’, 6-diamidino-2-phenylindole. Observations were done using an immunofluorescence microscope. Calculation of area density in each cell to perceive the expressions of cytoplasmic and nuclear β-catenin, E-cadherin, and N-cadherin was conducted using ImageJ software, resulted in mean fluorescence intensity.RESULTS: There are significant differences in the expressions of cytoplasmic β-catenin, nuclear β-catenin, E-cadherin, and N-cadherin among SW480, COLO320DM, and HCT116 cell lines (p 0.05). SW480 cell line has a higher expression of nuclear β-catenin than the cytoplasm (p < 0.05).CONCLUSION: This study reveals differences in the expression of nucleic and cytoplasmic β-catenin, E-cadherin, and N-cadherin in three stages of CRC (Duke B, C, and D) refer to different activation invasion, migration, and metastatic processes. Furthermore, the high expression of nuclear β-catenin and N-cadherin in the early stage of CRC indicate there is a metastatic process in that stage, so nuclear β-catenin and cadherin can be considered as potential biomarkers in the early stage of this cancer.
