Transcriptomic profiling of splenic B lymphomas spontaneously developed in B cell-specific TRAF3-deficient mice

AbstractTRAF3, a critical regulator of B cell survival, was recently recognized as a tumor suppressor gene in B lymphocytes. Specific deletion of TRAF3 from B lymphocytes leads to spontaneous development of marginal zone lymphomas (MZL) or B1 lymphomas in mice. To identify novel oncogenes and tumor suppressive genes involved in malignant transformation of TRAF3-deficient B cells, we performed a microarray analysis to identify genes differentially expressed in TRAF3−/− mouse splenic B lymphomas. We have identified 160 up-regulated genes and 244 down-regulated genes in TRAF3−/−B lymphomas as compared to littermate control splenocytes. Here we describe the samples, quality control assessment, as well as the data analysis methods in detail for the transcriptomic profiling study.
