Cancer Metastasis and Metastasis Suppressors / 대한소화기학회지

ABSTRACT

Cancer metastasis, a complex and sequential network of cellular events involved in the migration and establishment of malignant cells from original site to distant foci, is an important and significant contributor to morbidity and mortality of cancer patients. Despite the clinical importance of cancer metastasis, its molecular and biochemical mechanism remains unclear. The identification of tumor suppressor gene confirmed that metastasis might involve the functional loss of genes that maintain the cellular differentiation optimally. Metastasis suppressor is defined by the ability to reduce the metastatic property of cancer cells without affecting its tumorigenesis. Since NM23 was first identified in 1988 as a metastasis suppressor, several metastasis suppressor genes have been identified and characterized. In this article, we review the complex and multi-step process of cancer metastasis and describe the recent progress of metastasis suppressors in the studies of identified. Consequently, we hope to introduce the new therapeutic target for the metastasis suppressors in cancer patients.
