TranscriptomicsWhole genome gene expression profiling in Adult T-cell Leukemia (ATL) cells and in Normal CD4+ T-cells
HTLV-1 infected individuals stay as carriers for their lifetimes, while the rest of 5% are killed by ATL. ATL leukemogenesis is a complex process involving accumulation of multiple genetic abnormalities in HTLV-1 infected cells. To clarify genetic events underlying ATL leukemogenesis, we conducted c...

TranscriptomicsWhole genome gene expression profiling in CD4+ T-cells, FACS-sorted based on CADM1/CD7 expression levels, in Adult T-cell Leukemia-lymphoma (ATL) patients, HTLV-1 carriers, and in healthy volunteers.
CADM1 overexpresion and stepwise downregulation of CD7 in CD4+T-cells from ATL patients and HTLV-1 carriers accurately reflect the process of disease, i.e., oligoclonally and clonally exanding cells are accumulated in D (CADM1posCD7dim) and N (CADM1posCD7neg) populations, respectively. Moreover, gen...

TranscriptomicsInfluence of ATL-type Helios overexpression or WT-Helios/Ikaros knockdown on gene expression profile in Jurkat cells
It has been known that aberrant isoforms of Ikaros family ptoteins are expressed in malignant cells. We identified that PBMC of ATL (acute T-cell leukemia) patients expresses different patterns of Helios isoforms compared with normal PBMC. In order to investigate the biological impact of ATL-type He...

TranscriptomicsAffymetrix SNP array data for acute T-cell leukemia/lymphoma (ATL)
SNP array analysis was performed using 168 ATL specimens. To obtain genotypes and intensities for each SNP, Affymetrix 250K SNP arrays were performed for 168 ATL samples.
