To evaluate the possible functional implications of MALAT1 expression we searched for coding genes that were significantly correlated, either positively or negatively, with MALAT1 in the different CLL subgroups (M-CLL and U-CLL and epigenetic subtypes) (Supplementary Table S3 online) and we subsequently performed pathway enrichment analyses. Here, MALAT1 is linked to B-cell chronic lymphocytic leukemia.
