We isolated by low strigency screening of a human erythroleukemia cDNA library (K562) 45 indipendent clones hybridizing to a Kruppel-like (HF.10) zinc finger cDNA. The expression of 15 such cDNAs in human hematopoietic cell lines was investigated. Preliminary sequence analysis of the zinc finger motifs in these cDNAs indicate that they belong to a subclass of the Cys-Cys/His-His motif, showing the highest homology to the Wilm's tumor and EGR1, EGR2 cDNAs.

The Kruppel-like protein ZNF224 is a co-factor of the Wilms' tumor 1 protein, WT1. We have previously shown that ZNF224 exerts a specific proapoptotic role in chronic myelogenous leukemia (CML) K562 cells and contributes to cytosine arabinoside-induced apoptosis, by modulating WT1-dependent transcription of apoptotic genes. Here we demonstrate that ZNF224 gene expression is down-regulated both in BCR-ABL positive cell lines and in primary CML samples and is restored after imatinib and second generation tyrosine kinase inhibitors treatment. We also show that WT1, whose expression is positively regulated by BCR-ABL, represses transcription of the ZNF224 gene. Finally, we report that ZNF224 is significantly down-regulated in patients with BCR-ABL positive chronic phase-CML showing poor response or resistance to imatinib treatment as compared to high-responder patients. Taken as a whole, our data disclose a novel pathway activated by BCR-ABL that leads to inhibition of apoptosis through the ZNF224 repression. ZNF224 could thus represent a novel promising therapeutic target in CML.
