Abstract:
AIM: To transfer 4 full-length WT1 isoforms cDNA into the leukemia cell line NB_4 so as to provide a cell model for studying the WT-1 gene function. METHODS: The eukaryotic expression recombinant vectors for WT1 isoforms (pCB6+/WT1) were introduced into the leukemia cell line NB_4 by electroporation. The positive cell clones were screened by G418 culture. The integration of WT1 gene isoforms in NB_4 cells as confirmed by PCR. The mRNA and protein of WT1 were detected by RT-PCR and Western blotting. RESULTS: WT1 gene isoforms were successfully transferred into NB_4 cells. WT1 mRNA and protein expression in the G418-selected cells increased remarkably compared with the control. CONCLUSION: WT1 gene isoforms were effectively transferred into NB_4 cells by electroporation and stably expressed in the transfected cells.
