TranscriptomicsEndogenous siRNAs derived from transposons and mRNAs in Drosophila somatic cells
Small interfering RNAs (siRNAs) direct RNA interference (RNAi) in eukaryotes. In flies, somatic cells produce siRNAs from exogenous double-stranded RNA as a defense against viral infection. Here, we identify 21-nt long, endogenous siRNAs (endo-siRNAs) corresponding to transposons and heterochromatic...

TranscriptomicsDeep sequencing of MYC DNA-binding sites in Burkitt's lymphoma
Background: MYC is a transcription factor encoded by the c-MYC gene (thereafter termed MYC). MYC is key transcription factor involved in many central cellular processes including ribosomal biogenesis. MYC is overexpressed in the majority of human tumours including aggressive B-cell lymphoma especial...

TranscriptomicsHistone acetylation and DNA demethylation of T-cells result in an anaplastic large cell lymphoma-like phenotype.
A characteristic feature of anaplastic large cell lymphoma (ALCL) is the significant reduction of the T-cell expression program despite its T-cell origin, a finding very similar to the loss of B-cell identity of classical Hodgkin lymphoma (cHL). Previously we demonstrated that epigenetic mechanisms ...

TranscriptomicsThe Oscillating miRNA 959-964 cluster impacts Drosophila feeding time and other circadian outputs [miRNA-seq].
Using high throughput sequencing of Drosophila head RNA, a small set of miRNAs that undergo robust circadian oscillations in levels were discovered. We concentrated on a cluster of six miRNAs, mir-959-964, all of which peak at about ZT12 or lights-off. The data indicate that the cluster pri-miRNA is...

TranscriptomicsPAX5 overexpression is not enough to reestablish the mature B-cell phenotype in classical Hodgkin lymphoma
In lymphomas derived from mature B cells the expression of the transcription factor PAX5 is maintained whereas classical Hodgkin lymphoma displays significantly reduced PAX5 expression despite its derivation from mature B cells. To elucidate the functional role of PAX5 in classical Hodgkin lymphoma,...

TranscriptomicsClassical Hodgkin lymphoma shows epigenetic features of an abortive plasma cellular differentiation: expression of A/T-treated vs. untreated B-cell lines
Background Epigenetic changes are involved in the extinction of the B-cell gene expression program of classical Hodgkin lymphoma. However, little is known regarding epigenetic similarities between classical Hodgkin lymphoma and plasma cell myeloma cells, both of which share an extinction of the gene...
