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:Despite the growing interest in the ruminants' gastrointestinal tract (GIT) microbiomes' ability to degrade plant materials by animal husbandry and industrial sectors, only a few studies addressed browsing ruminants. The present work describes the taxonomic and functional profile of the bacterial and archaeal communities from five different gastrointestinal sections (rumen, omasum-abomasum, jejunum, cecum and colon) of browsing Capra hircus, by metabarcoding using 16S rRNA genes hypervariable regions. The bacterial communities across the GITs are mainly composed of Bacillota and Bacteroidota. Prevotella was the leading bacterial group found in the stomachs, Romboutsia in the jejuna, and Rikenellaceae_RC9_gut_group, Bacteroides, UCG-010_ge, UCG-005, and Alistipes in large intestines. The archaeal communities in the stomachs and jejuna revealed to be mainly composed of Methanobrevibacter, while in the large intestines its dominance is shared with Methanocorpusculum. Across the GITs, the main metabolic functions were related to carbohydrate, amino acid, and energy metabolisms. Significant differences in the composition and potential biological functions of the bacterial communities were observed among stomachs, jejuna and large intestines. In contrast, significant differences were observed among stomachs and jejuna verse large intestines for archaeal communities. Overall different regions of the GIT are occupied by different microbial communities performing distinct biological functions. A high variety of glycoside hydrolases (GHs) indispensable for degrading plant cell wall materials were predicted to be present in all the GIT sections.
