Overexpression of oncogene c-kit is detected in 80% patients with acute myeloid leukemia (AML). A transgenic model cell line expressing oncogene c-kit was obtained by transduction with a recombinant retrovirus. We have designed small interfering RNAs (siRNAs) that efficiently suppress the expression of activated oncogene c-kit. Further, small hairpin RNAs (shRNAs) targeting c-kit mRNA were designed and expressed in lentiviral vectors. We report a stable reduction in c-kit expression following the introduction of shRNAs into model cells, as well as Kasumi-1 cells from a patient with AML.
