Next Generation Sequencing Facilitates Comparative Transcriptomes Analysis for different Yarrowia lipolytica strains synthesizing different levels of β-carotene as end products.

ABSTRACT: Purpose: According to comparative transcriptomes data, the differentially expressed genes within these selected Y. lipolytica strains can be digged out and further analyzed, seeking potential targets that were tuned drastically and might improve β-carotene production when modified. Methods: mRNA profiles of three Y. lipolytica strains ctrl, Y5_2, Y5_3 (each named as Yl_5_1, Yl_5_2, Yl_5_3 in related manuscript) were generated in triplicate using illumina. Sequencing libraries were generated using NEBNext® Ultra™ RNA Library Prep Kit for Illumina® (NEB, USA) and index codes were added to each sample. The library preparations were sequenced on an Illumina Hiseq 4000 platform. 150 bp paired-end reads were generated as raw data. The read counts for each gene in the genome were summarized as processed data. Results: In all strain samples, the transcriptome data for all 6145 genes throughout genome were detected. The results showed that the expression levels of nearly half of the total genes were tuned to a higher or a lower value. Conclusions: There were 2848 differentially expressed genes between strain ctrl and Y5-2 and this number was 2889 for ctrl vs. Y5_3. The GO and KEGG enrichment of these differentially expressed genes would be further operated for exploring drastically regulated functions and pathways.

Next Generation Sequencing Facilitates Comparative Transcriptomes Analysis for different Yarrowia lipolytica strains synthesizing different levels of lycopene as end products.

Project description:Purpose: According to comparative transcriptomes data, the differentially expressed genes within these selected Y. lipolytica strains can be digged out and further analyzed, seeking potential targets that were tuned drastically and might improve lycopene production when modified. Methods: mRNA profiles of three Y. lipolytica strains yl_12, yl_11, yl_10 (each named as A4AX1-1, A4AX1-24, A4AX1-25 in related manuscript) were generated in triplicate using illumina. Sequencing libraries were generated using NEBNext® Ultra™ RNA Library Prep Kit for Illumina® (NEB, USA) and index codes were added to each sample. The library preparations were sequenced on an Illumina Hiseq 4000 platform. 150 bp paired-end reads were generated as raw data. The read counts for each gene in the genome were summarized as processed data. Results: In all strain samples, the transcriptome data for all 4890 genes throughout genome were detected. The results showed that the expression levels of most genes basically kept unchanged. However, the levels of certain genes were tuned to a higher or a lower value. Conclusions: There were 329 differentially expressed genes between strain yl_12 and yl_11 and this number was 490 for yl_12 vs. yl_10. The GO and KEGG enrichment of these differentially expressed genes would be further operated for exploring drastically regulated functions and pathways.

Next Generation Sequencing Facilitates Comparative Transcriptomes Analysis for Saccharomyces cerevisiae lines generated by SCRaMbLE

Project description:Purpose: According to comparative transcriptomes data, the differentially expressed genes within these selected scrambled yeast strains can be digged out and further analyzed, seeking potential targets that were tuned drastically and might improve β-carotene production when modified. Methods: mRNA profiles of two Saccharomyces cerevisiae strains H0, S3 (each named as yJBH000 and yJBH012 in related manuscript) were generated in triplicate using illumina. Sequencing libraries were generated using NEBNext® Ultra™ RNA Library Prep Kit for Illumina® (NEB, USA) and index codes were added to each sample. The library preparations were sequenced on an Illumina Hiseq 4000 platform. 150 bp paired-end reads were generated as raw data. The read counts for each gene in the genome were summarized as processed data. Results: The yJBH012 had an obviously different pattern of global transcription as compared with the control yJBH000. The upregulation of 589 genes and down regulation of 236 genes were observed in this analysis.

Double-negative T cell therapy alone or in combination with oral UDCA alleviates primary biliary cholangitis in mice

Project description:Methods: The DNT cells incubation with anti-CD3/CD28 antibodies were stimulated with UDCA (60uM) for 48 hours, then transcriptome sequencing studies were performed on DNT cells RNA.Transcriptome sequencing libraries were generated using NEBNext® Ultra™ RNA Library Prep Kit for Illumina® (NEB, USA) following manufacturer’s recommendations and sequenced on an Illumina Hiseq platform (Illumina, San Diego, CA). Sequences were aligned to the reference genome with TopHat and processed with Cufflinks, which quantifies each transcript in each sample using reference annotations produced by the University of California Santa Cruz UCSC. Differentially expressed genes with a fold change of >=1.41 and pvalue <= 0.05 between UDCA treated and control DNT cells were submitted to GO and KEGG enrichment analysis, which uses unbiased methods to assess pathway enrichment.

Medium pH influences citric acid and lipid production in oleaginous yeast Yarrowia lipolytica

Project description:The goal of this study is to find out how Yarrowia lipolytica W29’s transcriptome changes in response to different pHs in certain medium, where the production of citric acid and lipid vary significantly at different pHs. The changes in transcriptome will give us insight about the mechanism of citric acid and/or lipid production are regulated. We harvested Y. lipolytica cells from bioreactor cultures from three different pHs: 2.0, 4.0 and 6.0 in triplicates. We sequenced the mRNA by Illumina HiSeq 2500 and generated an average of 20 million reads for each sample. We did not find distinct gene expression changes for the enzymes right downstream the intersection where citrate is cleaved into acetyl-CoA. Instead, from gene ontology enrichment analysis, we observed proteins with transport activities were overrepresented in gene groups that were up-regulated higher pH conditions, where citric acid secretion is favored.
