Description
Adenosine binds to 4 G protein-coupled receptors located on the cardiomyocyte (A1-R, A2a-R, A2b-R and A3-R) and modulates cardiac function during both ischemia and load-induced stress. While the role of adenosine receptor-subtypes has been well defined in the setting of ischemia-reperfusion, far less is known regarding their roles in protecting the heart during other forms of cardiac stress.

Description
We reported that both conventional and adipose-specific Naa10p deletions in mice result in increased energy expenditure, thermogenesis, beige adipocyte differentiation and activation. Mechanistically, Naa10p acetylates the N-terminus of Pgc1α and prevents it from interacting with Ppar𝛾 to activate key genes, such as Ucp1, involved in beige adipocyte function. We used microarrays to profile the gene expression changes by Naa10p KO in inguinal white adipose tissues (iWATs) derived from mice fed with high fat diet for 15 weeks.

Description
DNA methylation is thought to induce a transcriptional silencing through the combination of two mechanisms: the repulsion of transcriptional activators that do not recognize their binding sites when methylated, and the recruitment of transcriptional repressors that specifically bind methylated DNA. Methyl CpG Binding Domain proteins MeCP2, MBD1 and MBD2 belong to the latter category. However, the exact contribution of each protein in the DNA methylation dependent transcriptional repression occurring during development and diseases remains elusive. Here we present MBD2 ChIPseq data generated from the endogenous protein in an isogenic cellular model of human mammary oncogenic transformation. In immortalized or transformed cells, MBD2 was found in one fourth of methylated regions and associated with transcriptional silencing. Depletion of MBD2 induces upregulations of genes bound by MBD2 and methylated in their transcriptional start site regions. MBD2 was partially redistributed on methylated DNA during oncogenic transformation, independently of DNA methylation changes. Genes downregulated during this transformation preferentially gained MBD2 binding sites on their promoter. Depletion of MBD2 in transformed cells induced the upregulation of some of these repressed genes, independently of the strategy used for the abrogation of oncosuppressive barriers. Our data confirm that MBD2 is a major interpret of DNA methylation, and show an unreported dynamic in this interpretation during oncogenic transformation. Overall design: RNAseq of untreated HMEC-hTERT cells, siCtrl, siMBD2 or DAC treated HMLER cells, siCtrl or siMBD2 treated HME-ZEB1-RAS and HME-shP53-RAS cells, in duplicates.

Description
CD4 T cells can differentiate into a hetergenous population of effector T cells. A population of cytotoxic CD4 T cells can be generated against influenza challenge, however identifying these cells have been challenging. The expression of NKG2A/C/E on CD4 T cells identifies CD4 T cells with cytotoxic potential thus allowing further characterization of this subset of CD4 effector cells.

Description
Samd14 was discovered as a novel GATA-2 target gene. Samd14 increased hematopoietic progenitor levels/activity, promoted signaling by a pathway instrumental for hematopoietic stem/progenitor cell regulation (Stem Cell Factor/c-Kit), and c-Kit rescued Samd14 loss-of-function phenotypes Overall design: A control shRNA or an shRNA targeting Samd14 was retrovirally introduced to fetal liver ex vivo cultures. Progenitor cells (CD71-, Ter119-) were isolated and analyzed from these cultures

Description
Macrophage dysfunction and polarization plays key role in chronic inflammation associated with diabetes and its complications. However, the effect of diabetes on macrophage transcriptome including long non-coding RNAs is not known. Here, we analyzed global changes in transcriptome of bone marrow macrophages isolated from type 2 diabetic db/db mice and control littermates db/+ mice using high throughput RNA-seq technique. Data analysis showed that expression of genes relevant to fibrosis, cell adhesion and inflammation were altered in diabetic db/db mice relative to control db/+ mice. Furthermore, expression of several known and novel long non coding RNAs and nearby genes was altered in db/db mice. Gene ontology and IPA showed activation of signaling netwroks relevant to fibrosis, cell adhesion and inflammatory pathways . This study for the first time demonstrated that diabetes profoundly affects macrophage transcriptome including expression of long non coding RNAs and altered the levels of genes relevant to diabetes complications. Overall design: Bone marrow macrophages were isolated from 12 weeks old type 2 diabetic male db/db mice and control littermates db/+ mice. These were differentiated in culture for 7-8 days in the presence of 10 ng/ml of MCSF-1 (BMMC) or 20 ng/ml of GM-CSF (BMGM). Then RNA was extracted and used for RNA-seq.

Description
The BET (bromodomain and extra terminal) protein family members including BRD4 bind to acetylated lysines on histones and regulate the expression of important oncogenes, e.g., MYC and BCL2. Here we demonstrate the sensitizing effects of the histone hyperacetylation inducing pan-histone deacetylase inhibitor (HDI) panobinostat (PS) on human AML blast progenitor cells (BPCs) to the BET protein inhibitor JQ1. Treatment with JQ1 but not its inactive enantiomer (R-JQ1) was highly lethal against AML BPCs expressing mutant NPM1c+ with or without co-expression of FLT3-ITD, or AML expressing MLL fusion oncoprotein. JQ1 treatment reduced binding of BRD4 and RNA polymerase II to the DNA of MYC and BCL2, and reduced their levels in the AML cells. Co-treatment with JQ1 and the HDAC inhibitor panobinostat (PS) synergistically induced apoptosis of the AML BPCs, but not of normal CD34+ hematopoietic progenitor cells. This was associated with greater attenuation of MYC and BCL2, while increasing p21, BIM and cleaved PARP levels in the AML BPCs. Co-treatment with JQ1 and PS significantly improved the survival of the NOD/SCID mice engrafted with OCI-AML3 or MOLM13 cells (p < 0.01). These findings highlight co-treatment with a BRD4 antagonist and an HDI as a potentially efficacious therapy of AML.
