Illumina HiSeq 2000, Affymetrix Human Gene 2.0 ST Array (hugene20st)
Description
The indisputable role of epigenetics in cancer and the fact that epigenetic alterations can be reversed have favored development of epigenetic drugs. In this study, we have design and synthesize potent novel, selective and reversible chemical probes that simultaneously inhibit the G9a and DNMTs methyltransferase activity. In vitro treatment of hematological neoplasia (Acute Myeloid Leukemia-AML, Acute Lymphoblastic Leukemia-ALL and Diffuse Large B-cell Lymphoma-DLBCL) with the lead compound CM-272, inhibited cell proliferation and promoted apoptosis, inducing interferon stimulated genes and immunogenic cell death. CM-272 significantly prolonged survival of AML, ALL and DLBCL xenogeneic models. Our results represent the discovery of first-in-class dual inhibitors of G9a/DNMTs and establish this chemical series, as a promising therapeutic tool for unmet needs in hematological tumors.

A toxicogenomic analysis from liver of different pharmacological active coumarins (mammea A/BA+A/BB 3:1 and soulatrolide ) was performed on mice treated (20mg/kg/daily) for a whole week to evaluate if such compounds possess or could develop a hazardous profile on liver.

Description
Here we show that Tet1 is down-regulated in mouse nucleus accumbens (NAc), a key brain reward structure, by repeated cocaine administration which enhances behavioral responses to cocaine. Through genome-wide 5hmC profiling, we identified 5hmC changes selectively clustered in both enhancer and coding regions of genes with several annotated neural functions. By coupling with mRNA sequencing, we found cocaine-induced alterations in 5hmC correlate positively with alternative splicing. We also demonstrated that 5hmC alteration at certain genes lasts up to a month after cocaine exposure. Overall design: RNA Nac samples were collected at various time points after 7 daily cocaoine ip administration for 5hmC and transcriptome analysis

Description
We have generated iPSCs from monosomy X (Turner Syndrome), trisomy 8 (Warkany Syndrome 2), trisomy 13 (Patau Syndrome) and partial trisomy 11;22 (Emanuel Syndrome), using either skin fibroblasts from affected individuals or amniocytes from antenatal diagnostic tests. These cell lines stably maintain the karyotype of the donors and behave like embryonic stem cells (ESCs) in all tested assays. Turner Syndrome iPSCs were used for further studies including global gene expression analysis and tissue-specific directed differentiation. Multiple clones displayed lower levels of the pseudoautosomal genes ASMTL and PPP2R3B than the controls. Moreover, they could be transformed into neural-like, hepatocyte-like and heart-like cells but displayed insufficient up-regulation of the pseudoautosomal placental gene CSF2RA during embryoid body (EB) formation. These data support that abnormal organogenesis and early lethality in Turner Syndrome are not caused by a tissue-specific differentiation blockade but rather involves other abnormalities including impaired placentation.

Description
Gene expression of T47D-MTVL human breast cancer cells expressing Dox-inducible shRNAs against histone H1.4 (120sh) or multiple H1 variants (225sh) Overall design: Stable breast cancer-derived cell lines expressing an shRNA against one of each of the histone H1 isoforms in response to doxycycline (Dox) were grown for six days in the presence or absence of Doxicycline, RNA extracted and high-thorughput sequenced. Cell lines used: inducible shRNA against H1.4 or multiple H1 variants and random shRNA-expression vector.

Description
The liver transcriptomes of two female groups (High and Low) with phenotypically extreme intramuscular fatty acid composition were sequenced using RNA-Seq [accn: SRA053452, subid: 86092, Bioproject: PRJNA168072]. A total of 146 and 180 unannotated protein-coding genes were identified in intergenic regions for the L and H groups, respectively. In addition, a range of 5.8 to 7.3% of repetitive elements was found, with SINEs being the most abundant elements. The expression in liver of 186 (L) and 270 (H) lncRNAs was also detected. The higher reproducibility of the RNA-Seq data was validated by RT-qPCR and porcine expression microarrays, therefore showing a strong correlation between RT-qPCR and RNA-Seq data (ranking from 0.79 to 0.96), as well as between microarrays and RNA-Seq (r=0.72). A differential expression analysis between H and L animals identified 55 genes differentially-expressed between groups. Pathways analysis revealed that these genes belong to biological functions, canonical pathways and three gene networks related to lipid and fatty acid metabolism. In concordance with the phenotypic classification, the pathways analysis inferred that linolenic and arachidonic acids metabolism was altered between extreme individuals. In addition, a connection was observed among the top three networks, hence suggesting that these genes are interconnected and play an important role in lipid and fatty acid metabolism.
