To examine the direct effect of induced CDKN1C expression in rhabdoid tumor cells, G401 clones over-expressing full-length human CDKN1C under the control of the tamoxifen inducible promoter (pcDNA3 UAS CDKN1C and pEFpuro/GEV), were selected in geneticin and puromycin. This evidence concerns the gene CDKN1C and rhabdoid tumor.
