Project description:A huge number of microorganisms are colonized in human gut and the balance of their composition is closely related to human health. Recently, many probiotics such as bifidobacteria or lactobacilli have been introduced in our life as effective agents. However, we have not well understood their beneficial mechanisms including host-bacterial crosstalk To analyze the differences of gene expression between BA- or BL-associated murine colonic epithelium, we performed comparative transcriptomic analysis. Bifidobacterium adolescentis (BA)-associated mice and Bifidobacterium longum (BL)-associated mice were used. Colonic epithelium was isolated and gene expression profile was analyzed. Each 3 samples were analyzed.

Project description:SARS-CoV-2 induces widespread transcriptomic changes in host cells upon infection, in part through activation and modulation of innate immunity pathways and downstream gene regulation. However, the mechanisms by which SARS-CoV-2 and its evolutionary variants differentially affect host cell transcriptomic states remain largely unclear. Through chromatin proteomic (iDAPT-MS) analysis, we found that although SARS-CoV-2 and other pathogenic coronaviruses exhibit similar proteomic shifts on chromatin, SARS-CoV-2 uniquely promotes TP53 nuclear accumulation and activation. Parallel assessment of SARS-CoV-2 viral protein expression on host chromatin states (ATAC-seq) identifies intracellular spike protein as a key determinant of virus-mediated chromatin accessibility changes. Multilevel chromatin profiling reveals increased TP53 nuclear accumulation, TP53-associated chromatin accessibility changes, and TP53 target gene activation upon expression of SARS-CoV-2 alpha (B.1.1.7) and delta (B.1.617.2) spike variants relative to the ancestral spike sequence. TP53, ACE2, and furin cleavage are required for these changes, driving decreased cellular proliferation, increased cellular senescence, and increased cytokine release. Finally, BA.1 but not BA.2, BA.2.12.1, nor BA.4/BA.5 spike expression leads to attenuated TP53 activity and fusogenicity relative to ancestral spike. Our findings implicate spike-mediated host TP53 activation as a “rheostat” of COVID-19 pathogenicity.

Project description:Increasing energy expenditure by promoting the thermogenic program in brown adipocytes is a promising approach to combat human obesity. To fully exploit the potential of this approach a comprehensive understanding of the gene regulatory network that controls both lineage commitment and differentiation of brown cells is necessary. Here, we systematically examine the transcriptomic and epigenomic transitions from mesenchymal stem cells to brown adipocytes (BA) and we perform a comparative analysis with differentiating white adipocytes (WA). We identify coding genes, lncRNA genes, and microRNA genes that are differentially regulated upon BA differentiation. In addition, we generate genome wide reference maps for several chromatin marks throughout brown adipogenesis. We identify putative (super-)enhancers, super-enhancers controlled genes in brown and white adipocytes, as well as target genes of the brown lineage-committing factor BMP7. Finally we show that overexpression and knockdown of four putative novel adipogenic regulators (the kinase Pim1, and the transcription factors Six1, Rreb1, and Sox13), indeed affects BA differentiation, suggesting an important role in brown adipogenesis.

Project description:Burkitt lymphoma (BL) is a highly aggressive B cell non-Hodgkin lymphoma (B-NHL), which originates from germinal center (GC) B cells and harbors translocations deregulating the MYC oncogene. A comparative analysis of microRNAs (miRNAs) expressed in normal and malignant GC B cells identified miR-28 as significantly down-regulated in BL, as well as in other GC-derived B-NHL. We show that re-expression of miR-28 impairs cell growth and clonogenic properties of BL cells by modulating several targets including MAD2L1, a component of the spindle checkpoint whose down-regulation is essential in mediating miR-28-induced growth-arrest, and BAG1, an activator of the ERK pathway.

Project description:Blue light (BL) is an important environmental factor that plays critical role in algae growth and development. Saccharina japonica, as a typical brown alga, showed greatly affected by BL. However, little has been known about the regulation pathway of BL response in algae. microRNAs (miRNAs) participated in great number of life process regulation and may be also involved in the BL response in plants. To identify miRNAs from S. japonica and characterize their probable roles in BL response, we sequenced and compared small RNA libraries under BL irradiation and dark conditions. 20 potential novel miRNAs were identified from S. japonica. Bioinformatics analysis of the miRNAs indicated that their potential targets were involved in various biological processes. Based on differential expression analysis and qRT-PCR experiment, some probable miRNAs related to BL responses were selected for further verification of their function, such as miR398. Our results demonstrated that miRNAs might play vital roles in metabolism of S. japonica, including BL responses.
