Description
DNA methylation is an essential epigenetic modification, present in both unique DNA sequences and repetitive elements, but its exact function in repetitive elements remains obscure. Here, we describe the genome-wide comparative analysis of the 5mC, 5hmC, 5fC and 5caC profiles of repetitive elements in mouse embryonic fibroblasts and mouse embryonic stem cells. We provide evidence for distinct and highly specific DNA methylation/oxidation patterns of the repetitive elements in both cell types, which mainly affect CA repeats and evolutionary conserved mouse-specific transposable elements including IAP-LTRs, SINEs B1m/B2m and L1Md-LINEs. DNA methylation controls the expression of these retro-elements, which are clustered at specific locations in the mouse genome. We show that TDG is implicated in the regulation of their unique DNA methylation/oxidation signatures and their dynamics. Our data suggest the existence of novel epigenetic code for the most recently acquired evolutionary conserved repeats that could play a major role in cell differentiation. Overall design: Transcriptome (RNA-seq) analyses of shRNA treated MEFs (control, shSCR or Tdg knockdown, shTDG).

Description
CD19-specific CARs that comprise CD28 and CD3z signaling domains program highly performing effector functions that mediate potent tumor elimination, but they impart a relatively limited T cell lifespan. Increasing functional T cell persistence without reducing effector potency is therefore likely to further enhance the therapeutic success of 1928z CAR T cells. We demonstrate that the number and position of ITAMs in 1928z CAR T cells influence functional, phenotypic and transcriptional programs, resulting in profound effects on antitumor efficacy. Improved therapeutic potency of CAR T cells can thus be achieved by calibrating activation strength, thereby retaining memory functions and preventing exhaustion, without compromising effector functions. Our transcriptional analysis underscores the potential of ITAM dosage and position to direct different T cell fates. We were able to identify a novel CAR design, termed 1XX, which programs a favorable balance of effector and memory signatures, inducing increased persistence of highly functional CARs with the replicative capacity of long-lived memory cells and potent effector functions. Overall design: In order to assess the different phenotypic and functional patterns of CARs encoding a single immunoreceptor tyrosine-based activation motif (ITAM), we compared the genome-wide transcriptional profiles of 1928z, 1XX and XX3 after CD19 antigen stimulation of TRAC-edited naïve T cells. Sorted naïve (TN), stem cell memory (TSCM) and effector (TEFF) CD8+ T cells served as controls.

Description
Exposure to high levels of arsenic in drinking water is associated with several types of cancers including lung, bladder and skin, as well as vascular disease and diabetes. Drinking water standards are based primarily on epidemiology and extrapolation from higher dose experiments, rather than measurements of phenotypic changes associated with chronic exposure to levels of arsenic similar to the current standard of 10ppb, and little is known about the difference between arsenic in food as opposed to arsenic in water. Measurement of phenotypic changes at low doses may be confounded by the effect of laboratory diet, in part because of trace amounts of arsenic in standard laboratory chows, but also because of broad metabolic changes in response to the chow itself. Finally, this series contrasts 8hr, 1mg/kg injected arsenic with the various chronic exposures, and also contrasts the acute effects of arsenic, dexamethasone or their combination. Male C57BL/6 mice were fed on two commercially available laboratory diets (LRD-5001 and AIN-76A) were chronically exposed, through drinking water or food, to environmentally relevant concentrations of sodium arsenite, or acutely exposed to dexamethasone.

Description
We generate ZNF423 knockdown and control DAOY cells with lentivirus that co-expressed the fluorescent protein mCherry. We performed whole genome RNA sequencing (RNA-seq) of three batched of cultured ZNF423 KD or control KD cells. The sequence reads were analyzed by Homer followed by edgeR. The analyzed RNA-seq results showed differential expression profile including 12 known cilia genes, and 3 of these were validated with qRT-PCR on mouse granule cell precursors. This study proved data how ZNF423 linked to cilia complexes. Overall design: RNA-seq in three batched of control and ZNF423 KD cells(generated by lentivirus delivered shRNA targeting ZNF423 sequence).

Description
To investigate the relationship between histones, chaperone function, and cataracts, we performed RNA-seq, isothermal titration calorimetry (ITC), size-exclusion chromatography, and gel electrophoresis of histones. The RNA-seq of postnatal lenses from 2-day-old cryaa -R49C mice revealed increased histone gene expression, suggesting that a a-crystallin mutation regulates histones via a transcriptional mechanism . Overall design: RNA-seq studies on lenses of 2-day-old wild-type and 2-day-old cryaa-R49C heterozygous mutant and cryaa-R49C homozygous mutant knock-in mice; and 14-day old wild-type and 14-day-old cryab-R120G heterozygous mutant and cryab-R120G homozygous mutant knock-in mice

Description
Mononuclear phagocytes are a diverse cell family that occupy all tissues and assume numerous functions to support tissue and systemic homeostasis. Our ability to investigate the roles of individual subsets is limited by an absence of approaches to ablate gene function within specific sub-populations. Using Nr4a1-dependent Ly6Clow monocytes as a representative cell type we show that enhancer deletion addresses these limitations. Combining ChIP-Seq and molecular approaches we identify a single, conserved, sub-domain within the Nr4a1 enhancer that is essential for Ly6Clow monocyte development. Mice lacking this enhancer lack Ly6Clow monocytes but retain Nr4a1 gene expression in macrophages during steady state and in response to LPS. Nr4a1 is a key negative regulator of inflammatory gene expression and decoupling these processes allows Ly6Clow monocytes to be studied without confounding influences. Enhancer targeting possesses greater specificity than cre recombinase-mediated gene deletion, providing a route to generate loss-of-function models in closely related cell types. Overall design: Paired End mRNA sequencing of FACS purified primary murine MDP, cMoP, Ly6Chi and Ly6Clow monocytes from the bone marrow and Ly6Chi and Ly6Clow monocytes from the peripheral blood

Description
Introduction: Mechanisms that contribute to the pathogenesis of liver damage caused by hepatitis C virus (HCV) are not fully understood. Our previous work on liver biopsies from chronic HCV patients has shown modulation of the expression of certain cell cycle proteins indicating HCV-induced modifications of cell cycle events. We therefore hypothesize that HCV infection disrupts normal regulation of cell cycle that contributes to disease progression. Objective: To identify molecular disruptions during the course of HCV-associated disease progression, using liver biopsy specimens of chronic hepatitis C patients. Methods: Liver biopsy samples classified on histological basis as early (fibrosis stage 0-1) or advanced (fibrosis stage 3-4) disease stage were studied using oligonucleotide array ( HG U133 Plus 2.0, Affymetrix GeneChip System). For comparison, liver specimens from patients with non-viral hepatitis were also analyzed by microarray. Expression data was analyzed using Genespring (GX 7.2) and Ingenuity Pathway analysis (3.0). The differential expression of selected cell cycle genes (cyclin D2, KPNA2, HERC5 and Bcl-2) identified after microarray analysis was confirmed by quantitative real-time RT-PCR. Results: Microarray analysis revealed two-fold or greater transcriptional change in 792 genes of the total 38,500 known human genes in HCV-advance disease stage (HCV-A) as compared to HCV-early disease stage (HCV-E). Most of the genes have a defined role in immune response, extracellular matrix and cell cycle and apoptosis.
