Project description:Chicken 60-mer oligonucleotide microarray, including 39854 cDNA and ESTs, entire Marek’s disease virus and avian influenza virus genomes, and 150 chicken microRNAs, was developed. Cecal tonsil, ileum, liver and spleen from 6 chickens were selected for hybridization to validate the microarray performance. There are 2886, 2886, 2660, 358, 3208 3355, and 3710 genes significantly expressed between liver and spleen, spleen and cecal tonsil, cecal tonsil and ileum, liver and cecal tonsil, liver and ileum, spleen and ileum at the P<10-7. Number of tissue specific genes for cecal tonsil, ileum, liver and spleen was 95, 71, 535, and 108, respectively with p < 10-7. More than 95% of spots had high SNR (>10). Keywords: characteristics of newly developed microarray using different normal tissue
Project description:HH stage 21 chicken dorsal mesentery is laser microdissected into four morphological compartments, and subject to global expression analyses on Affymetrix Chicken 3' microarray Goal is to identify genes expressed in each of left epitelium, left mesenchyme, right mesenchyme, right epithelium; genes on the left may be direct or indirect transcriptional targets of Pitx2.
