The basal expression level of MALAT1 was determined in six mantle cell lymphoma derived cell lines (Z-138, Mino, REC-1, Jeko-1, JVM2 and Granta-519) (Additional file 2: Figure S1), the MCL cells with higher expression of MALAT1 (Mino and Jeko-1) which were used for additional experiments. This evidence concerns the gene MALAT1 and mantle cell lymphoma.
