Description
Recently there has been growing interest in the immunomodulatory effects of endogenous danger signals known as alarmins. In this study, we explore a new combination therapy of anti-CD4 depleting antibody with an alarmin, high mobility group nucleosome binding protein 1 (HMGN1). Extremely low dose of HMGN1 with anti-CD4 depleting antibody exerted robust anti-tumor effects in Colon26 subtaneous murine model. To understand transcriptomic differences of CD8+ T cells in the tumor-bearing mice after treated with anti-CD4 depleting antibody or combination therapy of HMGN1 with anti-CD4 depleting antibody, we performed CD8 T cell transcriptome analysis using 3'SAGE-seq and Ion Proton sequencer. Overall design: CD8+ T cells were purified from single cell suspension of each implanted mouse tumor by lineage sorting (CD45-CD11b-B220-CD49b-Ter119-CD4-CD8+) through FACSAria. CD8 T cell transcriptome analysis were generated by 3'SAGE-seq using Ion Proton sequencer.

Description
Purpose: Assess whether knocking out the UMLILO lncRNA altered the expression of genes transcribed within the CXCL chemokine TAD Outcome: To confirm whether the effect of UMLILO was limited to the CXCL TAD. Adeno-associated viral vectors (AAVs) were constructed that contain CRISPR/Cas9 and guides targeting UMLILO to delete the full length UMLILO transcript. RNAseq was performed on a transduced THP-1 population to verify genome-wide effects of UMLILO depletion. This revealed that IL8, CXCL1, 2, 3 transcription was abrogated, but a similar effect was not seen for genes located outside of the CXCL TAD boundary Overall design: AAVs were constructed that contain CRISPRs that harness non homologous end joining (NHEJ) to target UMLILO by deleting the genomic region encoding UMLILO, but not its promoter. The THP-1 monocytic cell line was transduced with the AAVs containing the CRISPRs for 1.5 weeks. Controls were transduced with AAV vector plasmids expressing SpCas9.

Description
Hematopoietic stem cells (HSCs) are now recognized as a heterogeneous population in self-renewing and differentiation capabilities. However, fundamental mechanisms governing the heterogeneity remain uncertain. We here show that special AT-rich sequence-binding protein 1 (SATB1), a global chromatin organizer, is involved in the mechanisms. Analyzing hematological lineage-restricted SATB1 knock out mice proved that SATB1 is indispensable for both self-renewal and normal differentiation of adult HSCs. Using SATB1/Tomato knock-in mice, we subdivided HSCs according to SATB1 intensity. Culture experiments and RNA-sequencing revealed essential differences between SATB1- and SATB1+ HSCs regarding lineage potential. Overall design: Total RNAs isolated from SATB1- and SATB1+ CD150+ Flt3- LSK cells were applied for RNA-sequencing, and then amount of change of each genetic expression in SATB1+ HSCs compared with SATB1- HSCs were calculated.

Description
The molecular features of hepatocellular carcinoma arising from non-alcoholic fatty liver disease (NAFLD-HCC) are not well known. In this study, we investigated the mechanism by which NAFLD-HCC survives in a fat-rich environment. We found that caveolin (CAV)-1 was overexpressed in clinical specimens from NAFLD-HCC patients. HepG2, HLE, and HuH-7 HCC cell lines showed decreased proliferation in the presence of the saturated fatty acids palmitic acid and stearic acid, although only HLE cells expressed high levels of CAV-1. HLE cells treated with oleic acid (OA) showed robust proliferation, whereas CAV-null HepG2 cells showed reduced proliferation and increased apoptosis. CAV-1 knockdown in HLE cells attenuated the OA-induced increase in proliferation and enhanced apoptosis. Liquid chromatography-tandem mass spectrometry analysis revealed that the levels of OA-containing ceramide, a pro-apoptotic factor, were higher in HepG2 and CAV-1-deficient HLE cells than in HLE cells, suggesting that CAV-1 inhibits apoptosis by decreasing the level of OA-containing ceramide. These results indicate that CAV-1 is important for NAFLD-HCC survival in fatty acid-rich environments and is a potential therapeutic target.

Description
The source of aldosterone in 30 to 40 % of patients with primary hyperaldosteronism (PA) is unilateral aldosterone-producing adenoma (APA). The mechanisms causing elevated aldosterone production in APA are unknown. Herein, we examined expression of G-protein coupled receptors (GPCR) in APA and demonstrate that compared to normal adrenals there is a general elevation of certain GPCR in many APA and/or ectopic expression of GPCR in others. RNA samples from normal adrenals (n = 5), APAs (n = 10), and cortisol-producing adenomas (CPAs) (n=13) were used on 15 genomic expression arrays, each of which included 223 GPCR transcripts presented in at least one out of 15 of the independent microarrays. The array results were confirmed using real-time RT-PCR (qPCR). Four GPCR transcripts exhibited a statistically significant increase that was greater than 3-fold compared to normal adrenals, suggesting a general increase in expression compared to normal adrenal glands. Four GPCR transcripts exhibited a greater than 15-fold increase of expression in one or more of the APA samples compared to normal adrenals. qPCR analysis confirmed array data and found the receptors with the highest fold increase in APA expression to be luteinizing hormone receptor (LH-R), serotonin receptor 4 (HTR4), gonadotropin-releasing hormone receptor (GnRHR), glutamate receptor metabotropic 3 (GRM3), endothelin receptor type B-like protein (GPR37), and ACTH receptor (MC2R). There are also sporadic increased expressions of these genes in the CPAs. Together, these findings suggest a potential role of altered GPCR expression in many cases of PA and provide candidate GPCR for further study.

Description
Histone H3.3 is a highly conserved histone H3 replacement variant in metazoans, and has been implicated in many important biological processes including cell differentiation and reprogramming. Germline and somatic mutations in H3.3 genomic incorporation pathway components, or in H3.3 encoding genes, have been associated with human congenital diseases and cancers, respectively. However, the role of H3.3 in mammalian development remains unclear. To address this question, we generated H3.3 null mouse models through classical genetic approaches. We found H3.3 plays an essential role in mouse development. Complete depletion of H3.3 leads to developmental retardation and early embryonic lethality. At the cellular level, H3.3 loss triggers cell cycle suppression and cell death. Surprisingly, H3.3 depletion does not dramatically disrupt gene regulation in the developing embryo. Instead, H3.3 depletion causes dysfunction of heterochromatin structures at telomeres, centromeres and pericentromeric regions of chromosomes leading to mitotic defects. The resulting karyotypical abnormalities and DNA damage lead to p53 pathway activation. In summary, our results reveal that an important function of H3.3 is to support chromosomal heterochromatic structures, thus maintaining genome integrity during mammalian development. Overall design: RNA-seq in embryos at E10.5 comparing 3 samples with the following genotype Trp53-/-; H3f3afl/-; H3f3bfl/-; Sox2-CreTg/0 to three samples with the following genotype Trp53-/-; H3f3afl/+; H3f3bfl/+; Sox2-CreTg/0
