Project description:Gene expression was studied using PancChip5.0 in 15 tissues. Most tissues were from the adult mouse, except for fetal pancreas (e18.5) and placenta. Adult tissues studied were: adrenal gland, pancreas, brain, heart, kidney, liver, lung, ovary, parotid gland, pituitary gland, small intestine, stomach and testis. All were studied in duplicate except for the pituitary, the liver, and the stomach. All samples were pooled samples. Tissues were taken from 3 males and 3 females, with the exception of the gonadal tissues, and the fetal tissues were sex was not determined.

Project description:ChIP-Sequencing on Shox2-HA E12.5 and E13.5 Limb and Palate, as well as Pbx on E12.5 limb . Abstract: Vertebrate appendage patterning is programmed by Hox-TALE factors-bound regulatory elements. However, it remains enigmatic which cell lineages are commissioned by Hox-TALE factors to generate regional specific pattern and whether other Hox-TALE co-factors exist. In this study, we investigated the transcriptional mechanisms controlled by the Shox2 transcriptional regulator in limb patterning. Harnessing an osteogenic lineage-specific Shox2 inactivation approach we show that despite widespread Shox2 expression in multiple cell lineages, lack of the stylopod observed upon Shox2 deficiency is a specific result of Shox2 loss of function in the osteogenic lineage. ChIP-Seq revealed robust interaction of Shox2 with cis-regulatory enhancers clustering around skeletogenic genes that are also bound by Hox-TALE factors, supporting a lineage autonomous function of Shox2 in osteogenic lineage fate determination and skeleton patterning. Pbx ChIP-Seq further allowed the genome-wide identification of cis-regulatory modules exhibiting co-occupancy of Pbx, Meis, and Shox2 transcriptional regulators. Integrative analysis of ChIP-Seq and RNA-Seq data and transgenic enhancer assays indicate that Shox2 patterns the stylopod as a repressor via interaction with enhancers active in the proximal limb mesenchyme and antagonizes the repressive function of TALE factors in osteogenesis. Shox2/TALE For ChIP-Seq, the list of libraries below, including controls, were generated [listed in the format of (antibody)-target-tissue-stage]: (α-HA)-Shox2-Limb-E12.5, (α-HA)-Shox2-Limb-E13.5, (α-HA)-Shox2-Palate-E12.5, (α-HA)-Shox2-Limb/Palate-E12.5, (α-Pbx)-Pbx-Limb-E12.5, Input (control), (α-HA)-Mixed Limb/Palate from Shox2+/+ mice-E12.5 (control). *The attached signal tracks(*.bigwig) were generated by âbdgcmp (MACS2) to filter out background signal(by filtering against the signal track obtained from (α-HA)-Mixed Limb/Palate from Shox2+/+ mice-E12.5 (control)) and subsequently convert to bigwig for analysis and visualization.

Project description:Metabolic surgery has been increasingly recommended for obese diabetic patients, but questions remain as to its effectiveness for nonobese diabetic patients and its mechanism that leads to glucose homeostasis independently of weight loss. Roux-en-Y gastric bypass (RYGB), as one of the most effective metabolic operations, excludes a portion of stomach with the proximal intestine (biliopancreatic limb, BL) and rearranges the distal end of the intestine into a Y-configuration, in which food can flow from the upper stomach pouch through the Roux limb (RL). To address the above questions to RYGB surgery, we designed a series of surgical procedures in Goto-Kakizaki （GK） rats to assess the relationship between glycemic control independent of weight loss and RL length in the RYGB procedure and studied the molecular mechanism of the RL from a systematic and comprehensive view.

Project description:This dataset is comprised of RNA samples from 11 horses of various ages and sex that comprise the following tissues: Adipose Tissue, Adrenal Cortex, Adrenal Medulla, Aorta, Articular Cartilage (foal), Bladder, Bone, Bone Marrow, Cecum, Cerebrum, Cornea, Embryo (whole embryo, 34d), Endometrium (preg. day 16), Endometrium (preg. day 50), Epididymus, Hoof (germinal epithelium), Kidney, Large Intestine, Liver, Lung Lymph Node, Lymphocytes (activated), Muscle (cardiac), Muscle (skeletal, tongue), Muscle (skeletal), Muscle (smooth), Ovary, Pancreas, Pituitary (anterior), Pituitary (posterior), Placental Villous, Retina, Salivary Gland, Skin (full thickness), Spinal Cord, Spinal Root Ganglia, Spleen (red pulp), Spleen (white pulp), Stomach, Synovial Membrane, Tendon (superficial digital flexor, foal), Testes, Thymus, and Vena Cava. This study was carried out in strict accordance with the recommendations in the Guide for the Care and Use of Laboratory Animals of the National Institutes of Health. Tissue samples for total RNA isolation were collected under a protocol (00814A2004) reviewed and approved by the Office of Research Integrity, Institutional Animal Care and Use Committee, at the University of Kentucky (PHS Assurance Number: A3336-01). Two micrograms of mRNA from each tissue sample was used to generate the final RNA pool. The pooled sample was Illumina and 454 sequenced with the aim to improve equine gene structural annotation.

Project description:The overall goal of this project is to investigate the role of Erk2-mediated signaling in regulating the cellular metabolism of cranial neural crest (CNC) cells during palate development. Here, we conducted gene expression profiling of palate tissue from wild type mice as well as those with a neural crest specific conditional inactivation of the Erk2 gene. The latter mice exhibit micrognathia, tongue defects and cleft palate, which is among the most common congenital birth defects and observed in many syndromic conditions.
