Abstract Objective To construct recombinant lentivirus with Slug gene for further exploring the effect of Slug in metastatic recurrence. Methods The Slug gene was acquired from the breast cancer cell MDA-MB-231 by PCR assay, which was then connected into linearized GV367 vector digested by Age Ⅰ/Nhe I enzyme. The positive clones were identified by PCR and sequencing analysis. The constructed lentiviral vectors with Slug gene were then transfered into 293T cell lines. The lentivirus titer was detected by the fluorescence method. Results The lentiviral vector with Slug gene was successfully constructed and obtained, the virus titer of which was 5×108 TU/mL. Conclusion The lentiviral with Slug gene are successfully constructed, which will provide the experimental foundation for further exploring the effect of Slug in metastatic recurrence.
