Aberrant alternative splicing of human zinc finger gene ZNF268 in human hematological malignancy.

The human ZNF268 gene was initially described as a gene associated with early human embryogenesis and was later implicated in human leukemia due to the identification of an alternatively splice form in leukemia patients. To systematically evaluate the correlation of ZNF268 with human hematological malignancy, expression of different alternatively spliced forms of ZNF268 mRNA in peripheral blood of 45 patients with hematological malignancies and 17 healthy donors were analyzed by reverse transcription-polymerase chain reaction (RT-PCR) and nested PCR. We demonstrated that presence of ZNF268a, ZNF268c, ZNF268f and ZNF268g were significantly different between the patients and healthy donors (P<0.05). Our study thus suggests that aberrant alternative splicing of ZNF268 is a potential prognostic factor of and may contribute to human hematological malignancies.
