<P>Dynamin 2 is known as a protein involved in cell migration and endocytosis. We aimed to investigate the association between dynamin 2 expressions and tumor progression in early cervical carcinoma (IB1-IIA). Dynamin 2 expression was evaluated at protein level in thirty seven paraffin-embedded, formalin-fixed tissues including four normal cervix tissues and compared with pathologic risk factors for recurrence after surgery in thirty three patients with squamous cell carcinoma of the cervix. The expression of dynamin 2 was not different according to clinical stage and lympho-vascular space invasion. However, there were inverse correlations between dynamin 2 expression and the depth of invasion in cervix (p = 0.003) and lymph node (LN) metastasis (p = 0.001). To evaluate the mechanism of dynamin 2 in tumor invasion and metastasis, we performed an in vitro experiment with dynamin 2 siRNA using several cervical carcinoma cell lines such as HeLa, MS751 and SiHa cells. We found the inhibition of dynamin 2 using specific siRNA enhanced the expression of matrix metalloproteinase-2. These results suggested that dynamin 2 might be involved in preventing tumor invasion and LN metastasis, possibly in relation with extracellular matrix degradation, and may be a prognostic marker for these risk factors in early squamous cell carcinoma of the cervix.</P>
