chronic lymphocytic leukemia chromatin immunoprecipitation assay, small interfering RNA-mediated repression CLL patients, Human Burkitt’s lymphoma cell line Daudi down-regulated N/A The transcription factor BSAP (B-cell-specific activator protein) directly interacts with Dleu2, the host gene containing the miR-15a/16-1 loci, and by negative regulation of the Dleu2 promoter, results in repression of miR-15a/16-1 expression. 23995789
chronic lymphocytic leukemia chromatin-immunoprecipitation (ChIP) that are associated with activated transcription; semi-quantitative and quantitative methods (aPRIMES, BioCOBRA, MCIp, MassARRAY, and bisulfite sequencing) CLL cells N/A N/A the tumor suppressor mechanism at 13q14.3 is a cluster of genes controlled by two lncRNA 23593011
multiple myeloma FISH myeloma cases N/A locus A cdr of approximately 350 kb was identified at 13q14 with the proximal border approximately 120 kb centromeric from d13s319, encompassing an area rich in expressed sequence tagged sites and containing dleu1, dleu2, and rfp2 genes. 12461754
B-cell chronic lymphocytic leukemia N/A N/A N/A mutation B-cell chronic lymphocytic leukemia: frequent chromosomal imbalance. 11072235 LncRNADisease

B-cell chronic lymphocytic leukemia N/A N/A N/A N/A No expression of 1b4/leu2 was detectable in b-cll, regardless of the 13q14 status. these results indicate that allelic loss and mutation of a gene within the mdr is an unlikely pathogenetic mechanism for b-cll. 11264177
lymphocytic leukemia N/A N/A N/A locus Dleu2 is an antisense transcript that encompasses the Kcnrg and Trim13 genes, as well as two microRNA genes, Mirn16-1 and Mirn15a, which have been previously identified in lymphocytic leukemia. 18562676 LncRNADisease

chronic lymphocytic leukemia qPCR etc. blood differential expression locus In 13q14.3, where several tumor suppressor genes, including the miRNA genes miR-16-1 and miR-15a, are co-regulated by the two long non-coding RNA genes DLEU1 and DLEU2 that span the critical region. 19347735 LncRNADisease Lnc2Cancer

chronic lymphocytic leukemia qPCR, FISH etc. blood differential expression N/A Leu1 and Leu2 genes are strong candidates as tumor suppressor gene(s) involved in B-CLL leukemogenesis. 9395242 LncRNADisease Lnc2Cancer
myeloma qPCR, Western blot, Northern blot, Luciferase reporter assay etc. myeloma tissue, cell lines (HEK293, U2OS etc.) down-regulated expression The microRNAs miR-15a and miR-16-1 are downregulated in multiple tumor types and are frequently deleted in chronic lymphocytic leukemia (CLL), myeloma and mantle cell lymphoma. DLEU2 negatively regulates the G1 Cyclins E1 and D1 through miR-15a/miR-16-1 and provide evidence that these oncoproteins are subject to miR-15a/miR-16-1-mediated repression under normal conditions. We also demonstrate that DLEU2 overexpression blocks cellular proliferation and inhibits the colony-forming ability of tumor cell lines in a miR-15a/miR-16-1-dependent way. 19591824 LncRNADisease Lnc2Cancer
