Expression of Manganese Superoxide Dismutase Suppression of Fibrosarcoma Metastasis by Elevated
نویسندگان
چکیده
A mouse fibrosarcoma cell line (FSa-II), which exhibits low endogenous levels of manganese Superoxide dismutase, was transfected with a human manganese Superoxide dismutase complementary DNA. Fifty clones were screened for manganese Superoxide dismutase activity by the Superoxide dismutase activity gel assay. Activity of the positive clones was measured by the nitro blue tetrazolium-reduction assay in the presence of cyanide. Three cell lines exhibiting a range of activity were chosen to be trans planted into syngeneic mice. The results indicated that the metastasis rate for all transfected cells was significantly less than that of control cells.

متن کاملOverexpression of Manganese Superoxide Dismutase Selectively Modulates the Activity of Jun-associated Transcription Factors in Fibrosarcoma Cells1
Manganese superoxide dismutase (MnSOD) Is reduced in a variety of tumor cells and has been proposed to be a new type of tumor suppressor gene. The mechanism(s) by which MnSOD suppresses cancer development is currently unknown, However, expression of this antioxidant might play a significant role in maintaining cellular redox status. The relationship between MnSOD expression and modulation of DN...

متن کاملManganese superoxide dismutase enhances the invasive and migratory activity of tumor cells.
Clinically significant elevations in the expression of manganese superoxide dismutase (Sod2) are associated with an increased frequency of tumor invasion and metastasis in certain cancers. The aim of this study was to examine whether increases in Sod2 activity modulate the migratory potential of tumor cells, contributing to their enhanced metastatic behavior. Overexpression of Sod2 in HT-1080 f...
