miRNA expression profiles of chicken embryonic visceral tissue infected with F48E9 or La Sota

Project description:Three cDNA libraries of mixed visceral tissues from F48E9, La Sota, or uninfected chicken embryos were constructed, and small-RNA deep sequencing was conducted to detect the expression levels of small-RNAs. Intergroup comparisons were used to identify changes in miRNA expression caused by NDV infection. La Sota affected the expression of 61 miRNAs (36 upregulated and 25 downregulated) at 36 hpi, and F48E9 infection altered the expression levels of 66 miRNAs (33 upregulated and 31 downregulated).

RNA sequencing-based analysis of the visceral tissue transcriptome of chicken embryo infected with F48E9 or La Sota

Project description:We attempted to characterize the transcriptome of the chicken embryo during Newcastle disease virus (NDV) infection using RNA-sequencing analysis. The cDNAs derived from Total RNA of the pooled visceral tissues infected with F48E9 or La Sota were sequenced and analysed. The collected clean reads covered about 4.02% (2,341,868 reads) of the entire F48E8 reference sequence, while only 0.02% reads (13,886) were mapped to the La Sota genome. RNA-Seq datasets from groups La Sota, F48E9 and control, were respectively mapped to 71.76%, 68.55% and 70.05% of the reference genome Galgal 4.73. Compared with the control, 2,035 and 1,604 differentially expressed genes of hosts were found responding to F48E9 and La Sota infection, respectively. GO and KEGG pathway enriched various signalling pathways with elements playing roles in enhancing or preventing viral infection, like IFP35, NMI, Mx, OAS*A, IFITM5, STAT1 and IFNβ. So far, we know that velogenic NDV made far more transcripts during infection and caused significant impact on the host, showing a large number of genes in various pathways at high levels of expression.

Comparision of La-RNA-binding between wild type La and sumoylation deficient La mutant (K41/200R) in HEK293 cells.

Project description:We performed a RNA immunoprecipitations experiments using gfp-specific antibodies to precipitate gfp-tagged La proteins from from gfp-La wild type and sumoylation deficient La mutant (K41/200R) cells and found that specific mRNAs are preferentially enriched gfp-La wild type RIPs when compared to sumoylation deficient La mutant (K41/200R) RIPs.

Hypoxia effect on embryonic hearts of Tibetan Chicken, Dwarf Recessive White Chicken and Shouguang Chicken

Project description:Adaptation to hypoxia is a complicated and important physiological course for organisms, but the genetic mechanism underlying the adaptation is not fully understood yet. Tibetan Chicken (T), an indigenous chicken breed in China which inhabit in high areas with an altitude above 2,900 meters. Shouguang Chicken(S) and Dwarf Recessive White Chicken (DRW), two lowland chicken breeds, were used as control groups. The heart was the first functional organ to develop during the embryonic development. Furthermore, the heart is an efficient energy converter utilizing the most appropriate fuel for a given environment. Therefore, GeneChip® Chicken Genome Array was employed to identify the differentially expressed genes in embryonic hearts of Tibetan Chicken and two lowland chicken breeds in both hypoxic and normoxic incubating environments with a genome wide profile.

The Lupus autoantigen La prevents mis-channeling of tRNA fragments into the human microRNA pathway [miRNA-seq]

Project description:The Lupus autoantigen (La) is a single-stranded RNA-binding protein that stabilizes RNA polymerase III (pol III) transcripts and supports RNA folding. In addition, La has been implicated in different steps of the mammalian small RNA pathway. Here, we have analyzed effects of La depletion on the Argonaute (Ago)-bound small RNAs in human cells. We find that in the absence of La, distinct tRNA fragments are loaded into Ago protein complexes and our data suggests that La prevents the production and loading of such tRNA fragments. However, one specific isoleucine tRNA escapes this regulation and produces both a functional tRNA as well as a microRNA (miRNA). We demonstrate that fully complementary 5' leader and 3' trailer of the pre-tRNA-Ile form a double-stranded RNA molecule that has low affinity to La. Instead, Exportin 5 (Xpo5) recognizes it as miRNA precursor and transports it into the cytoplasm for Dicer processing and Ago loading. Thus, La functions as gatekeeper to ensure correct tRNA generation and to protect the miRNA pathway from potentially functional tRNA fragments.

miRNA expression profiling in embryonic chicken heart

Project description:MicroRNAs are small non-coding RNA transcripts that regulate post-transcriptional gene expression. The millions of short sequence reads generated by next generation sequencing technologies make this technique explicitly suitable for profiling of known and novel microRNAs. A modification to the small-RNA expression kit (SREK, Ambion) library preparation method for the SOLiD sequencing platform is described to generate microRNA sequencing libraries that are compatible with the Illumina Genome Analyzer. High quality sequencing libraries can successfully be prepared from as little as 100 ng small RNA enriched RNA. An easy to use perl-based analysis pipeline called E-miR was developed to handle the sequencing data in several automated steps including data format conversion, 3' adapter removal, genome alignment and annotation to non-coding RNA transcripts. Both the sample preparation and E-miR pipeline were successfully used to determine cardiac enriched microRNA expression in stage 16 chicken embryos.
