Abstract
Introduction Colorectal cancer is among the three leading causes of cancer-related mortality worldwide. Approximately 50% of patients with colon cancer, the predominant type of colorectal cancer, develop liver metastasis, which [...]
LIM domain proteins are involved in several fundamental biological processes, including cell lineage specification, cytoskeleton organization and organ development. Zinc finger protein 185 (ZNF185) is one of the LIM domain proteins considered to be involved in the regulation of cellular differentiation and/or proliferation. However, the detailed functions and properties of ZNF185 in the multi-step process of cancer biology have not yet been elucidated. In this study, we analyzed the association between ZNF185 and the clinicopathological characteristics of colon cancer, such as patient age and gender, histological type, lymphatic and venous involvement, T and N status, liver metastasis and stage. ZNF185 protein expression was immunohistochemically analyzed and ZNF185 was detected in the cancer cells of 78 of the 87 colon cancer patients. The correlation between ZNF185 and histological type was significant (P=0.010, G-test). ZNF185 expression was also significantly correlated with liver metastasis (P=0.030, G-test). A multivariate analysis using the Cox proportional hazards model was performed among cause-specific survival rate, ZNF185 expression and clinicopathological characteristics. Histological type, liver metastasis and ZNF185 expression were found to be independent prognostic indicators (P=0.028, P Key words: zinc finger protein 185, colon cancer, liver metastasis, prognosis
