Project description:Transcriptional profiling of jejunum infected with Salmonella in three different chicken lines early in life. Samples were taken at 8, 24 and 48 hours post infection. Salmonella was orally ingested at day zero (hatch).
Project description:Comparison of three populations of OECs derived from the ONL of rats. The three populations were cultured employing the same culture medium but were maintained in vitro for a different amount of time (number of population doublings or PDs). OEC Ep cells were maintained for less than one week in vitro (less than 3 PDs); OEC Lp were maintained for over a year (more than 50 PDs) and TEG3 OEC cell line has been serially passed in culture for long-periods of time after genetic immortalization. Keywords: OEC cells, adaptation to long-term culture, genetic immortalization
Project description:Different chicken breeds exhibit distinct muscle phenotypes resulting from selective breeding, but little is known about the molecular mechanisms responsible for this phenotypic difference. Skeletal muscle is composed of a large number of heterogeneous cell populations. Differences in differentiation and interaction of cell populations play a key role in the difference of skeletal muscle phenotype. Here, skeletal muscle single-cell RNA sequencing in three developmental stages was performed on Daheng broiler (cultivated breed) and Tibetan chicken (native breed).
Project description:We sequenced single cells coming from three developmental stages of chicken forelimb. We identified different cell populations with distinct transcriptional profiles. The supplementary file contains processed UMI count matrices, which also include meta data of each cell, e.g. cluster.

Project description:Purpose:We have used RNA-seq to examine of differentially expressed miRNAs in chicken leg muscle of three different development stages (11 embryo ages, 16 embryo ages, and 1 day old post hatch chick).The aims of this study are characterization of miRNAs differentially expressed in different developmental stage of chicken embryo, using RNA sequence sample. Methods: On this study we used two embryonic stage and one post hatch chick leg muscle of Xinghua chicken breed. Total RNA from E11 day embryo, E16 day embryo and 1 day post hatch chick was isolated by TRIzol following the manufacturer’s protocol (Invitrogen, CA, USA). Each stages were designed two samples, and the total samples were six (three group × two sample/group) and RNA samples of six individuals were pooled with equal amounts, and then were subjected to Illumina deep sequencing. Results: After eliminating adaptor and low-quality reads, a total of 5,302,700, 6,556,747, 5,359,793, 4,213,112, 7,112,885 and 7,469,939 clean reads were obtained in group E11 (E11.1-E11.2), group E16 (E16.1-E16.2) and group P1 (P1.1–P1.2) libraries, respectively. The clean reads were aligned to the chicken genome databases, miRBase, Rfam, RepBase and mRNA. Conclusions:To assess miRNA expression during chicken embryo skeletal muscle development, we sequenced and analyzed leg muscle at 11 day embryo age, 16 day embryo age, and 1 days post hatch.
