Project description:The rat has been used extensively as a model for evaluating chemical toxicities and for understanding drug mechanisms. However, its transcriptome across multiple organs, or developmental stages, has not yet been reported. Here we show, as part of the SEQC consortium efforts, a comprehensive rat transcriptomic BodyMap created by performing RNASeq on 320 samples from 11 organs of both sexes of juvenile, adolescent, adult and aged Fischer 344 rats. We catalogue the expression profiles of 40,064 genes, 65,167 transcripts, 31,909 alternatively spliced transcript variants and 2,367 non-coding genes/non-coding RNAs (ncRNAs) annotated in AceView. We find that organ-enriched, differentially expressed genes reflect the known organ-specific biological activities. A large number of transcripts show organ-specific, age-dependent or sex-specific differential expression patterns. We create a web-based, open-access rat BodyMap database of expression profiles with crosslinks to other widely used databases, anticipating that it will serve as a primary resource for biomedical research using the rat model. We constructed a comprehensive RNA-Seq data set for studying the dynamics of the rat transcriptome using 320 RNA samples isolated from 11 organs (adrenal gland, brain, heart, kidney, liver, lung, muscle, spleen, thymus, and testes or uterus) from both sexes of Fischer 344 rats across four developmental stages (2-, 6-, 21-, and 104-weeks-old). Four biological replicates were used for each of the 80 sample groups.

Project description:miRNA sequencing of Pacific oyster Crassostrea gigas for different organs and developmental stages. Two RNA pools were created and sequenced by mixing the samples before and after the developmental stage "D shaped larvae". Then ten developmental samples and eleven samples from 7 organs were sequenced.

Project description:Among urochordates (tunicates)âthe closest living relatives of vertebratesâCiona intestinalis is increasingly being used as a model organism in the field of developmental biology. Ciona intestinalis is the seventh animal which genome published; the ~120-Mbp euchromatin region is estimated to contain ~16,000 protein-coding genes. In addition, analyses of more than one million ESTs have provided the foundation for gene models and associated transcriptomes. The fertilized Ciona intestinalis egg develops into a tadpole larva with a simplified chordate body plan, and then it metamorphose into adult sea squirt of sessile filter feeder. One of interests in the field of developmental biology is to understand what kind of genes are expressed in the body and how spatially and/or temporally coordinated expression of genes is controlled. In this study, we investigated the entire gene expression of 11 organs of adult Ciona; the neural complex, branchial sac, esophagus, stomach, endostyle, intestine, body-wall muscle, heart, blood cells, ovary, and testis. Our data would provides basic information of transcriptome in each organ and help to understand gene expression control of organ specific genes. Gene expressions in 11 organs of adult Ciona intestinalis; blood cells, branchial sac, digestive grand, endostyle, esophagus, heart, body-wall muscle, neural complex, ovary, stomach and testis. Three independent experiments were performed at each tissue using different individuals for each experiment.

Project description:A maize array was fabricated with 5,376 unique expressed sequence tag (EST) clones sequenced from 4-day-old roots, immature ears and adult organ cDNA libraries. To elucidate organ relationships, relative mRNA levels were quantified by hybridization with embryos, three maize vegetative organs (leaf blades, leaf sheaths and roots) from multiple developmental stages, husk leaves and two types of floral organs (immature ears and silks). Clustering analyses of the hybridization data suggest that maize utilizes both the PEPCK and NADP-ME C(4) photosynthetic routes as genes in these pathways are co-regulated. Husk RNA has a gene-expression profile more similar to floral organs than to vegetative leaves. Only 7% of the genes were highly organ specific, showing over a fourfold difference in at least one of 12 comparisons and 37% showed a two- to fourfold difference. The majority of genes were expressed in diverse organs with little difference in transcript levels. Cross-hybridization among closely related genes within multigene families could obscure tissue specificity. As a first step in elucidating individual gene-expression patterns, we show that 45-nucleotide oligo probes produce signal intensities and signal ratios comparable to PCR probes on the same matrix. Gene-expression profile studies with cDNA microarrays provide a new molecular tool for defining plant organs and their relationships and for discovering new biological processes in silico. cDNA microarrays are insufficient for differentiating recently duplicated genes. Gene-specific oligo probes printed along with cDNA probes can query individual gene-expression profiles and gene families simultaneously.
