High-throughput sequencing analysis identify miRNAs in 7dpf F1-zebrafish under β-diketone antibiotics exposure to F0-zebrafish

Project description:Small RNA high-throughput sequencing technology was used to characterize the miRNAs in F1-zebrafish after 90-day β-diketone antibiotic (DKA) exposure to F0-zebrafish at 6.25 and 12.5 mg/L. The small RNA libraries from 7-dpf F1-zebrafish were constructed. In total, 10,117,347, 9,818,830 and 12,049,949 raw reads were acquired, respectively, under the different DKA-exposure treatments (0, 6.25 mg/L and 12.5mg/L) from the three miRNAs libraries by Illumina sequencing. Low-quality reads were removed, which included 5' contaminants, those missing the 3' primer or insert tag, sequences with a poly A tail, and those shorter than 17 nt and longer than 25 nt. As a result, 8,141,146 (representing 312,735 unique sequences; control), 8,687,210 (representing 251,508 unique sequences; 6.25 mg/L), and 10,569,566 (representing 441,938 unique sequences; 12.5 mg/L) valid reads in the 17 to 25 nt size range were isolated for further analysis. The sRNAs from the three libraries were similar, and the unique sRNA reads were mainly distributed in the 20-24 nt range, among which 22 and 23 nt accounted for 41.8% and 20.0% of total unique sRNA reads, respectively. The 22-nt sRNAs were the most abundant, with the length distribution of counts of sequ-seqs and unique miRNAs displaying a normal distribution.

Characterization and profiling of liver microRNAs in cattle divergently selected for residual feed intake by RNA-sequencing

Project description:MicroRNAs (miRNAs) are short non-coding RNAs that post-transcriptionally regulate expression of mRNAs in many biological pathways. Here we report comprehensive miRNAs profiles by next-gen deep sequencing in Angus cattle divergently selected for residual feed intake (RFI) and identify miRNAs related to feed efficiency in beef cattle Results: Two microRNA libraries were constructed from pooled RNA extracted from livers of low and high RFI cattle, and sequenced by Illumina genome analyser. In total, 23,628,103 high quality short sequence reads were obtained and more than half of these reads were matched to the bovine genome (UMD 3.1). We identified 305 known bovine miRNAs (miRBase v.19). Bta-miR-143, bta-miR-30, bta-miR-122, bta-miR-378 and bta-let-7 were the top five most abundant miRNAs families expressed in liver, representing more than 63% of expressed miRNAs. We also identified 52 homologous miRNAs and 10 novel putative bovine-specific miRNAs, based on precursor sequence and the secondary structure and utilizing the miRBase (version 19). We compared the miRNAs profile between high and low RFI animals and ranked the most differentially expressed bovine known miRNAs. Bovine miR-143 was the most abundant miRNA in the bovine liver and comprised 20% of total expressed mapped miRNAs. The most highly expressed miRNA in liver of mice and humans, miR-122, was the third most abundant in our cattle liver samples. We also identified 10 putative novel bovine-specific miRNA candidates. Differentially expressed miRNAs between high and low RFI cattle were identified with 18 miRNAs being up-regulated and 7 other miRNAs down-regulated in low RFI cattle Conclusions: Our study has identified comprehensive miRNAs expressed in bovine liver. Some of the expressed miRNAs are novel in cattle. The differentially expressed miRNAs between high and low RFI give some insights into liver miRNAs regulating physiological pathways underlying residual feed intake in bovine

Overexpression of OsTZF8, a CCCH-Tandem Zinc finger, increases drought tolerance in rice by regulating stress related genes

Project description:Purpose: Next-generation sequencing (NGS) has been utilized for systems-based analysis of rice plants. The goals of this study were to compare the transcriptome between non-transgenic (NT) control and OsTZF8 overexpressing transgenic plants. Methods: Total RNAs were extracted from the whole plants of OsTZF8 overexpressing plants (T4 generation, line number #20) and non-transgenic (NT) plant using RNeasy plant mini kit (Qiagen, Germany) according to the manufacturer’s instruction. cDNA libraries were prepared from total RNAs using TruSeq RNA sample Prep kit (v2) (Macrogen, Korea). Two biological replicates were analyzed by RNA-sequencing analysis. Single-end sequences were obtained using IRGSP (v 1.0) and raw sequence reads were trimmed to remove adaptor sequence, and those with a quality lower than Q20 were removed using the Trimmomatic 0.32 software (Bolger et al., 2014). To map the reads to reference genome, all reads were assembled with annotated genes from the Rap-DB database [http://rapdb.dna.affrc.go.jp; IRGSP (v 1.0)] using TopHat software (https://ccb.jhu.edu/software/tophat/index.shtml). Conclusions: Our study has identified downstream candidate genes regulated by overexpression of OsTZF8.

RNA-seq analysis of miRNAs expression in chciken ALV-J-infected primary monocyte-derived macrophages (MDM) and uninfected control.

Project description:Purpose: The goals of this study are to investigate the differentially expressed miRNAs between ALV-J-infected primary monocyte-derived macrophages (MDM) and uninfected control by Illumina deep sequencing. Methods:Total RNA from two ALV-J-infected MDM (designated: J3h_1, J3h_2, J36h_1 and J36h_2) and two uninfected MDM samples (designated: NC3h_1, NC3h_2, NC36h_1 and NC36h_2) was isolated by TRIzol following the manufacturer’s instruction at 3 h post infection (hpi) and 36 hpi. RNA samples of two individuals within each group were pooled with equal amounts, and then were subjected to Illumina deep sequencing by Illumina Hiseq 2000. Results: compared to the uninfected MDM, we identified 13 significant up-regulated miRNAs and 2 significant down-regulated miRNAs in ALV-J infected MDM at 3 hpi, and 6 significant up-regulated miRNAs and 2 significant down-regulated miRNAs in ALV-J infected MDM at 36 hpi. Conclusions: Our results suggest that DE miRNAs involved in the immune response induced by ALV-J infection in MDM at 3 hpi. In addition, only 25 miRNAs-target DEGs were identified in MDM with ALV-J infection at 36 hpi, and these target DEGs can’t be significantly enriched in any GO terms and KEGG pathway..

Expression profiles of microRNA in bovine raw milk exosome and supernatant without exosome [mRNA array]

Project description:We have reported that microRNAs are present in human, bovine, and rat milk whey. Milk whey miRNAs were resistant to acidic condition and to RNase. Thus, milk miRNAs were thought to be present packaged into membrane vesicles like exosome. However, body fluid miRNAs have been reported that there are in different forms. To clarify which miRNAs species are exist in exosome and which species are exist in another form, we used bovine raw milk and purified total RNA from exosome fraction and ultracentrifugated supernatant fraction, and analyzed by miRNA microarray.
