Project description:Expression of known and predicted genes in tissues of Xenopus tropicalis (frog) pooled from multiple healthy individuals. Two-colour experiments with two different tissues hybridized to each array. Each tissue is arrayed in replicate with dye swaps. Tissues: Brain, Cartilage, Esophagus, Eye, Fat body, Femur, Gallbladder, Heart, Kidney, Large intestine, Liver, Lung, Muscle, Ovary, Oviduct, Skin, Small intestine, Spleen, Stomach, Testis
Project description:Comparing miRNAs expression levels in chorioamniotic membranes from women at term in labor (TL), women at term not in labor (TNL) and women who deliverd preterm (PTLC). The goal was to see if miRNA levels are indicators of preterm delivery or spontaneous labor at term. A two-channel technology was used in this experiment in which a pooled reference RNA was used for competitive hybridization. The pooled reference was generated at Exiqon in Denmark from a mixture of several human tissues (placenta, thyroid, brain, adipose, spleen, liver, colon, skeletal muscle, ovary, kidney, heart, cervix, testes, esophagus, small intestine, prostate, trachea, thymus, bladder, lung).
Project description:Here, we used single cell RNA-sequencing (scRNA-seq) to profile pluripotent stem cell derived human definitive endoderm and intestinal organoids (HIOs) at several timepoints of in vitro growth (7, 14, and 28 days) and after in vivo growth beneath the kidney capsule of a murine host (4 and 8 wks post-transplant). Additionally, we profiled HIOs grown in a non-adhesive alginate hydrogel and also CDX2 knockout HIOs. In order to benchmark the organoid cultures, we used scRNA-seq to profile primary human fetal esophagus (14.3 pcw, 16.7 pcw), stomach (6.7, 14.3, and 16.7 pcw), liver (14.4 pcw), small intestine ( 11.4 and 14.4 pcw) and colon (11.4, 14.4, and 18.9 pcw). Diverse cell lineages were captured across all tissues profiled, including: epithelium, mesenchyme, neurons, endothelium, and immune lineages.
Project description:The main goal of the study was to measure the epigenetic age (also known as DNA methylation age) of these tissues. Toward this end, we used the epigenetic clock software described in Horvath S (n=2013) DNA methylation age of human tissues and cell types. Genome Biology.2013, 14:R115. DOI: 10.1186/10.1186/gb-2013-14-10-r115 PMID: 24138928 Human DNA methylation Beadchip v1.2 was used to obtain n=64 Illumina DNA methylation arrays from 30 tissues. For each of the following tissues, we obtained at least 2 replicates: adipose, adrenal gland, aorta, bone, bone-marrow, breast, buccal cells, cartilage, cerebellum, colon, diaphragm, esophagus , frontal cortex, kidney, heart, hippocampus, liver, lung, lymph node, midbrain, muscle, occipital cortex, pancreas, pericardium skin, spleen, stomach, temporal cortex, thyroid, whole blood.
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:We report transcriptomic profiling from bulk heart, kidney, and liver tissues for 58 strains of the inbred mouse Collaborative Cross (CC). Each strain is represented by a male/female pair. Reads were first aligned to the pooled transcriptomes of the eight founder strains of the CC and then total gene counts were quantified using the EMASE and GBRS software tools. Total read counts can be further normalized for use in differential gene expression analysis, expression quantitative trait locus (eQTL) analysis, and integrative analyses with other -omic data sets measured on the same samples, including proteomics and phosphoproteomics.
Project description:To characterize genes, pathways, and transcriptional regulators enriched in the mouse cornea, we compared the expression profiles of whole mouse cornea, bladder, esophagus, lung, proximal small intestine, skin, stomach, and trachea. Total RNA was purified from esophagus, lung, proximal small intestine, skin, stomach, and trachea. Data from previous studies in the lab (cornea, GSE43155; bladder, GSE15770; and E18.5 skin, GSE15772) were utilized in the comparison.
