Results:①The amount of human colon carcinoma cell line SW480 treated by quercetin decreased. The morphology of partial SW480 cells was shrunk volume, integrated cell membrane, condensed cytoplasm, pyknotic chromatin, nuclear fragmentation. Apoptotic Corpuscles were found by electron microscope.②MTT colorimetric assay showed quercetin inhibited the growth of human colon carcinoma cell line SW480 in a time- and dose-dependent manner when the concentration of quercetin was 30、60、90μmol/L.③Flow cytometry analysis showed the cell cycle of SW480 cell was restricted in G1/S. G0/G1 phase rate increased and S phase rate decreased with increasing concentration of quercetin and time lasting.④ Zymogram analysis assay showed the secretion of matrix metalloproteinases in human colon carcinoma cell line SW480 treated by quercetin decreased. With increasing concentration of quercetin, the secretion of MMP-2 and MMP-9 decreased.⑤Immunohistochemistry method demonstrated the position expression of Cathepsin-D in SW480 cell was suppressed by quercetin in a time- and dose-dependent manner.
