Project description:We performed single nucleotide polymorphism (SNP) array profiling on 9 early T-cell precursor lymphoblastic lymphoma and 15 non-early T-cell precursor lymphoblastic lymphoma cases. Affymetrix SNP arrays were performed according to the manufacturer's directions on DNA extracted from unstained slides.
Project description:Childhood T-cell malignancies include T-cell acute lymphoblastic leukemia (T-ALL) and T-cell lymphoblastic lymphoma (T-LBL). T-ALL and T-LBL share common morphologic and immunophenotypic features and are treated with similar therapeutic approaches. Nonetheless, they show distinct clinical presentations suggesting that they may represent two different biological entities. In order to investigate the common and unique genetic aberrations of T-LBL and T-ALL, copy number alteration (CNA) analysis was performed on a subset of the samples analyzed by GEP Affymetrix SNP arrays were performed according to the manufacturer's directions on DNA extracted from diagnostic bone marrow aspirates or tumor tissue samples. Copy number analysis of Affymetrix 100K SNP arrays was performed for 9 T-ALL and 9 T-LBL pediatric samples. The samples from leukemia/lymphoma remission were used as references for copy number inference.
Project description:Molecular profiling of primary renal diffuse large B cell lymphoma unravels a proclivity for immune-privileged organ-tropism. Here, we used Affymetrix OncoScan CNV arrays to characterise somatic copy number variations in 29 prDLBCL cases.

Project description:Lymphoma DNA of five patients was analyzed using Affymetrix Genome-Wide Human SNP Array 6.0 according to the manufacturer’s instructions.
