Abstract:
This report describes a novel approach to cancer therapy that targets genes that are preferentially alternatively spliced and expressed in leukemia. We developed CD44v6 and CD44v8 splicing constructs fused with GFP or a humanized fragment of Pseudomonas aeruginosa exotoxin A (hPE24). Transfection of K562 leukemia cells with the GFP-linked splicing constructs led to subsequent production of detectable levels of GFP. Transfection of K562 cells with the hPE24-linked splicing constructs led to significant reduction of cell viability and an increase in the induction of apoptosis. Normal human PBMCs were unaffected by following transfection with these constructs.
