摘要: AIM: To study the suppressing effect of acetazolamide on tumor metastasis in vivo and observe protein alteration lung mice bearing Lewis carcinoma. METHODS: The functional role aquaporin-1 (AQP1) was investigated tumor tissues by SDS-PAGE and Western blot. tumor metastasis analyzed Lewis-lung-carcinoma model. Differential was identified SDS-PAGE, isoelectrofocusing (IEF) methods, peptide mass fingerprinting (PMF). RESULTS: Acetazolamide (40 mg/kg/d po for 21 d) dramatically reduced numbers of after sc inoculating carcinoma. inhibition rate of metastases 83.9 %. Simultaneously, AQP1 level and actin-cytoplasmic lungs containing metastatic deposits were found to be higher than that normal tissue. After treated with d, the expression obviously inhibited. CONCLUSION: can suppress metastasis, at least part, by inhibiting AQP1. actin-cytoplasmic may new prognostic molecules as well new therapeutic targets prevention and treatment tumor.
