To identify genes and pathways regulated by ETS1 in ABC-DLBCL, we performed microarray-based gene expression profiling in three ABC-DLBCL cell lines (SU-DHL-2, OCI-Ly10, HBL1) after silencing of the transcription factor using siRNA (Figures S1 and S2). The gene discussed is LINC00458; the disease is diffuse large B-cell lymphoma.
