摘要：

Background. THP-1 is a human monocytic leukemia cell line derived from a patient with acute monocytic leukemia. The cell line differentiates into macrophage-like cells by stimulation with phorbol myristate acetate (PMA). Although it has been used frequently as a model for macrophage differentiation in research including the FANTOM4/Genome Network Project, there are few reports on its genomic constitution. Therefore, we attempted to reveal the genomic aberrations in these cells with the microarray-based comparative genomic hybridization (aCGH) technique. Findings. We report large aberrations, including deletions 6p, 12p, 17p, and trisomy 8, and revealed breakpoints in the MLL and MLLT3 genes. Moreover, we found novel genomic aberrations such as a hemizygous narrow deletion partially containing the TP73 gene and homozygous deletions, including the CDKN2A, CDKN2B and PTEN genes. Conclusion. In this study, we identified 119 aberrant regions in autosomal chromosomes, and at least 16 of these aberrations were less than 100 kb, most of which were undetectable in the previous works. We also revealed a total of 4.6 Mb of homozygous deleted regions. Our results will provide a base to precisely understand studies involving the THP-1 cell line, especially the huge amount of data generated from the FANTOM4/Genome Network Project. © 2009 Kojima et al; licensee BioMed Central Ltd.
