Under steady-state conditions, eosinophils are abundantly found in the small intestinal lamina propria, but their physiological function is largely unexplored. We performed a global gene expression analysis to examine which genes are highly expressed by small intestinal eosinophils (CD11b+CD11c(int)MHCII-SiglecF+) compared with dendritic cells (CD11c+MHCII+).
Small intestinal eosinophils regulate Th17 cells by producing IL-1 receptor antagonist.

View SamplesLIN28A is a highly-conserved RNA-binding protein which is known to be involved in embryonic development, stem cell maintenance and proliferation. LIN28A is expressed in various types of cancer, and they are associated with advanced tumor malignancy. In embryonic stem cell, LIN28A specifically binds to let-7 precursors to suppress biogenesis of the let-7 microRNA family. In addition, LIN28A was reported to bind several mRNAs such as Oct4, cyclin A/B and histone H2A to activate their translation. For comprehensive understanding of the interaction between LIN28A and their target RNAs, we exploited UV-crosslinking and immunoprecipitation (CLIP) to capture their in vivo binding to target RNAs. LIN28A-binding RNAs were identified in a mouse embryonic stem cell line using multiple monoclonal and polyclonal antibodies. The result shows that LIN28 preferentially binds to let-7 precursors through GGAG binding motif, which is consistent with our previous results. We also identified that LIN28A binding is enriched in a certain subset of mRNAs. To understand the function of the novel LIN28A-mRNA binding, we carried out ribosome profiling from LIN28A-depleted mouse embryonic stem cells.

View SamplesIn the current study, we investigated the collective roles of protein tyrosine phosphatases (PTPs) and histone deacetylases (HDACs) on regulation of IRG expression in human choriocarcinoma cells by genome-wide transcriptional profiling. Logic-rules were optimized to derive rules governing gene expression patterns observed upon different combinations of treatment with PTP and HDAC inhibitors. The data reveal that IRGs can be divided into distinct subsets that are differentially modulated by co-treatment of Jar cells with IFN-? and PTP versus HDAC inhibitors, respectively. Furthermore, promoter analysis of the genes governed by the rules identifies transcription factor binding sites associated with the different gene subsets. Thus, the regulatory modes identified in this study provide insights into the complex regulation of inflammatory pathways at the fetal-maternal interface, as well as mechanisms that choriocarcinoma cells may utilize to promote their survival.

View SamplesRetinoic acid-inducible gene-I (RIG-I) is a cytosolic pathogen recognition receptor that initiates the innate immune response against many RNA viruses. RIG-I also has been shown to sense some DNA viruses, and host RNA polymerase III (RNA Pol III), a cytosolic DNA sensor, converts cytosolic AT-rich DNA into RNA to be sensed by RIG-I. We previously showed that the RIG-I restricts Kaposi Sarcoma-associated herpesvirus (KSHV) reactivation (J Virol. 2014 May;88(10):5778-87). In this study, we report that KSHV stimulates the RIG-I signaling pathway in an RNA Pol III-independent manner and subsequently induces type I IFN responses. Knockdown or inhibition of RNA Pol-III had no effect on IFN-ß induction by KSHV. By using CLIP (Cross-Linking and Immunoprecipitation) and RNA deep sequencing technologies, we identified multiple KSHV regions that give rise to RNA fragments binding to RIG-I, such as ORF810420-10496, ORF6411058-110675, Repeat region (LIR1)119059-119204, and ORF2543561-43650. The sequence dissimilarity between these fragments suggests that RIG-I detects a particular structure rather than a specific sequence motif. Synthesized ORF810420-10496 RNA stimulated RIG-I-dependent but RNA Pol III-independent IFN-ß signaling. In summary, some KSHV viral RNAs are sensed by RIG-I in an RNA Pol III-independent manner.

View SamplesSingle NG2-glia with GFP fluorescence labeling from PDGFRaCreER; mGFP mice was selected and aspirated into a glass pipette from hippocampal acute slices. In brief, cells were picked promptly by micromanipulation and immediately placed in lysis buffer. All NG2 glial cells were collected within 3 h after slice preparation. The selected NG2-glia were processed for single-cell RNA extraction and reverse transcription within 1 h and were subjected to RNA-sequencing.
