Abstract
The authors investigate the effects of human nonmetastatic clone 23 type 1 (nm23-H1) gene and fungal immunomodulatory protein—Ganoderma tsugae (FIP-gts) on the metastatic potential of cervical cancer cells and assess whether nm23-H1 can influence the action of FIP-gts using cell migration and invasion assays and gelatin zymography. The nm23-H1 gene was stably transfected into Caski cells, which lacked nm23-H1 expression. The results show that nm23-H1 stably transfected Caski cells exhibit reduced cell migration but no change of cell invasion and matrix metalloproteinase (MMP)—2 and —9 activities. FIP- gts reduced cell migration in SiHa and nm23-H1 transfected Caski cells more significantly compared with Caski cells and reduced invasion in Caski and nm23-H1—transfected Caski cells, but it exerted no influence on MMP-2 and MMP-9 activities in them. Conclusively, the nm23-H1 gene suppresses cervical cancer cell migration but not invasion and activities of MMP-2 and MMP-9 and enhances the inhibition of FIP-gts upon migration.
