Project description:Bicyclus anynana butterflies were reared at 17°C and 27°C to produce the dry and wet season forms. RNA was extracted using TRIzol from the heads of 12 individual animals ~0-3 hours after eclosing; 3 dry season females, 3 wet season females, 3 dry season males, and 3 wet season males. A TruSeq RNA Sample Preparation Kit v2 was used to make 12 double stranded cDNA libraries from polyadenylated RNA. We size selected for DNA at ~280-340 bp. Libraries were sequenced using a HiSeq 2500, paired end 100-cycle sequence run.
Project description:To investigate the impact of histone variants and modification on gene regulation, we report high-throughput profiles of six histone markers, H2A.Z, H3K4me2, H3K9me3, H3K27me3, H3K27ac, and H3K36me3, by ChIP-Seq in T-47D breast cancer cells. Libraries were sequenced with the Illumina HiSeq 2000 analyzer for 50 bp paired-end reads and over 20 million uniquely aligned reads were collected for each histone marker.
Project description:Using the HiSeqTM 2000 sequencing platform, the anther transcriptome of photo thermo sensitive genic male sterile lines (PTGMS) rice Y58S and P64S (Peiâai 64S) were analyzed at the fertility sensitive stage under cold stress.These datas would be most beneficial for further studies investigating the molecular mechanisms of rice responses to cold stress.
Project description:Purpose:In order to assess the toxicity of AFB1 in chicken liver and the mechanism of curcumin alleviating AFB1-induced liver toxicity in chicken, we established a co-administered model to investigate LncRNA and mRNA profiles of chicken liver. Methods: RNA extracted by Total RNA Extractor (Trizol) was utilized to construct the final library. Libraries were pooled and sequenced on a 150-bp paired-end Illumina HiSeq™ 2000 run. The sequencing data obtained from Illumina Hiseq™ was filtered to get clean reads using Trimmomatic. The reads themselves and their matching reads which length was less than 35nt were removed. Clean reads were aligned to the reference sequence (Gallus_gallus-5.0, NCBI) using HISAT2. Results: Sampling directly from the liver yielded sufficient quantities of RNA to assess transcripts from each chicken and mapped to 24,883 Gallus gallus genes. Conclusions: We used the method of RNA-seq to find the target genes and related signaling pathways involved in the co-administered (AFB1 and curcumin) and their underlying mechanisms.
Project description:BackgroundCapra hircus is an important economic livestock animal, and therefore, it is necessary to discover transcriptome information about their reproductive performance. In this study, we performed de novo transcriptome sequencing to produce the first transcriptome dataset for the goat ovary using high-throughput sequencing technologies. The result will contribute to research on goat reproductive performance.Method and resultsRNA-seq analysis generated more than 38.8 million clean paired end (PE) reads, which were assembled into 80,069 unigenes (mean size = 619 bp). Based on sequence similarity searches, 64,824 (60.6%) genes were identified, among which 29,444 and 11,271 unigenes were assigned to Gene Ontology (GO) categories and Clusters of Orthologous Groups (COG), respectively. Searches in the Kyoto Encyclopedia of Genes and Genomes pathway database (KEGG) showed that 27,766 (63.4%) unigenes were mapped to 258 KEGG pathways. Furthermore, we investigated the transcriptome differences of goat ovaries at two different ages using a tag-based digital gene expression system. We obtained a sequencing depth of over 5.6 million and 5.8 million tags for the two ages and identified a large number of genes associated with reproductive hormones, ovulatory cycle and follicle. Moreover, many antisense transcripts and novel transcripts were found; clusters with similar differential expression patterns, enriched GO terms and metabolic pathways were revealed for the first time with regard to the differentially expressed genes.ConclusionsThe transcriptome provides invaluable new data for a functional genomic resource and future biological research in Capra hircus, and it is essential for the in-depth study of candidate genes in breeding programs.
Project description:Wild-type and RBMX-overexpressed HEK293 cells where profiled at the transcriptome and translatome levels through polysomal profiling. Paired-end RNA-seq libraries were built and sequenced on an Illumina HiSeq 2000 machine to allow for accurate gene expression quantification and alternative splicing isoforms detection.
Project description:Genome-wide analysis of skin color-related lncRNA and mRNA expression in Koi carp, Cyprinus carpio L. LncRNAs information linked to fish skin color regulation is over-limited. In this study, Illumina sequencing and bioinformatics were primarily conducted on black, white and red skin colors of Koi carp. A total of 590,415,050 clean reads, 446,614 putative transcripts, 4,252 known and 72,907 novel lncRNAs were simultaneously obtained, respectively. Out of these genes, 92 significant differentially expressed lncRNAs and 722 mRNAs were excavated. Ccr_lnc5622441, Ccr_lnc765201 were found up-regulated in black and red skins; Ccr_lnc14074601 were up-regulated in white skin; and premelanosome proteins a (Pmela), tyrosinase (Tyr) were up-regulated in black skin, etc. Quantitative real-time PCR (qRT-PCR) further validated 12 differentially expressed genes were consistent with RNA-seq. Moreover, 70 lncRNAs on 107 target mRNAs in cis and 79 lncRNAs on 41,625 target mRNAs in trans were investigated, the networks revealed one lncRNAs can connected with numerous mRNAs, vice versa. These findings broadened the lncRNAs landscape of skin colors and provided new insights into the mechanisms underlying lncRNAs mediated pigmentation and differentiation in Koi carp.
