- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Follicular Lymphomas are blood tumors growing as spheres in patients. Before this study, there was no experimental model mimicking the 3D organization of these in vivo tumors. We develop such a model, called MALC, and observed a progressive enrichment in quiescent cells in these with time of culture; these cells were sorted, as their cycling counterparts, and their transcriptomes were compared. We used microarrays to detail the differential global gene expression profile between quiescent and cycling cells isolated from MALC.

Description
Follicular Lymphomas are blood tumors growing as spheres in patients. Before this study, there was no experimental model mimicking the 3D organization of these in vivo tumors. We develop such a model, called MALC, and performed a pan-genomic comparative analysis between MALC and classical suspension cultures. We used microarrays to detail the global gene expression profile induced by aggregated growth of lymphoma cells.

Description
Exhaustion markers are expressed by T lymphocytes in Follicular Lymphoma (FL). Through these, TIM-3 has been recently identified as a poor pronostic factor when expressed by FL CD4+ T cells.

Illumina HiSeq 2500
Description
Histone deacetylases (HDACs) catalyze the removal of acetyl groups from acetylated histone tails that consequently interact more closely with DNA, leading to chromatin state refractory to transcription. Zea mays HDA108 belongs to the Rpd3/HDA1 HDAC family and is ubiquitously expressed during development. The newly isolated hda108/hda108 insertional mutant exhibited many developmental defects: significant reduction in plant height, alterations of shoot and leaf development, alterations of inflorescence patterning and fertility. Western blot analyses and immunolocalization experiments revealed an evident increase in histone acetylation, accompanied by a marked reduction in H3K9 dimethylation, in mutant nuclei. The DNA methylation status, in the CHG sequence context, and the transcript level of ribosomal sequences were also affected in hda108 mutants, while enrichment in H3 and H4 acetylation characterizes both repetitive and non-repetitive transcriptional up-regulated loci. RNA-Seq both of young leaf and anthers indicated that transcription factor expression is highly affected and that the pollen developmental programme results as disrupted in hda108 mutants. Crosses between hda108/hda108 and epiregulator mutants did not produce any double mutant progeny indicating possible genetic interactions of HDA108 with distinct epigenetic pathways. Our findings indicate that HDA108 is directly involved in regulation of maize development, fertility and epigenetic regulation of genome activity. Overall design: Total RNA-Seq analysis of maize anthers at post-meiotic (PMeA) and mitotic (MiA) stages. 2 biological replicates for stage, each obtained by pooling anthers from three tassels per genotype were collected from wild-type and hda108 mutant plants.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Retinoic acid receptors (RARs) , and are key regulators of embryonic development. Hematopoietic differentiation is regulated by RAR, and several types of leukemia show aberrant RAR activity. We demonstrate that RAR plays an important role in cellular memory and imprinting by regulating the CpG methylation status of specific promoter regions.
Publication Title
Epigenetic regulation by RARα maintains ligand-independent transcriptional activity.

Illumina MouseRef-8 v2.0 expression beadchip
Description
NSD2 (also named MMSET and WHSC1) is a histone lysine methyltransferase that is implicated in diverse diseases and commonly overexpressed in multiple myeloma due to a recurrent t(4;14) chromosomal translocation. However, the precise catalytic activity of NSD2 is obscure, preventing progress in understanding how this enzyme influences chromatin biology and myeloma pathogenesis. Here we show that dimethylation of histone H3 at lysine 36 (H3K36me2) is the principal chromatin-regulatory activity of NSD2. Catalysis of H3K36me2 by NSD2 is sufficient for gene activation. In t(4;14)-positive myeloma cells, the normal genome-wide and gene-specific distribution of H3K36me2 is obliterated, creating a chromatin landscape that selects for a transcription profile favorable for myelomagenesis. Catalytically active NSD2 confers xenograft tumor formation and invasion capacity upon t(4;14)-negative cells and NSD2 promotes oncogenic transformation of primary cells in an H3K36me2-dependent manner. Together our findings establish H3K36me2 as the primary product generated by NSD2, and demonstrate that genomic disorganization of this canonical chromatin mark initiates oncogenic programming.
