Project description:To identify chromosomal alterations in ATL, SNP array analyses were performed in 19 leukemia cell samples from ATL patients and 9 ATL-related cell lines. ATL displayed complex chromosomal abnormalities, but it contained recurrent chromosomal amplification and deletion, including 14q11 and 14q32, which may be associated with the development of ATL. Affymetrix SNP arrays were performed according to the manufacturer's directions on DNA extracted from cryopreserved peripheral blood samples and from cell line samples.
Project description:We recently mapped 605 chromosomal breakpoints in 61 ATL cases by spectral karyotyping and identified chromosome 14q11 as one of the most common chromosomal breakpoint regions. To map the precise location of chromosomal breakpoints at 14q11, we performed single-nucleotide polymorphism (SNP)-based comparative genomic hybridization on leukemia cells from acute-type ATL patients. Copy number analysis of Affymetrix 50K SNP arrays was performed for leukemic cell samples from10 acute-type ATL patients.
