Abstract

Aim: To study the relationship between β-glucuronidase and the invasiveness of human colorectal carcinoma cell lines.

Methods: Six colorectal carcinoma cell lines, including three well-differentiated (CX1, CCL187, and CCL229) and three poorly differentiated ones (CCL227, CCL228, and Clone A), were analyzed by Fischman's method to determine the concentration of β-glucuronidase in the medium.

Results: Low levels of β-glucuronidase (activity range: 1.29 to 1.96 μg/106 cells·h) were associated with poor invasiveness. This finding was in contrast to the elevated levels of the enzyme (2.46-3.37 μg/106·h) detected in the medium derived from the more aggressively invasive cells (CCL 227, CCL 228, Clone A, and CCL 229).

Conclusion: Highly invasive colorectal carcinoma cells secreted higher levels of β-glucuronidase than the poorly invasive cells. Determination of secreted β-glucuronidase might represent a useful in vitro measurement tool to assess the invasiveness of colorectal carcinoma.

Keywords: Cell lines; Colorectal neoplasms; β-glucuronidase invasiveness.
