Project description:We have used Agilent whole genome arrays (v4) to compare the gene expression changes between 10-day-old Arabidopsis wild type seedlings and arf2-8 (Ellis et al., 2005), gnc gnl (Richter et al., 2011) and arf2 gnc gnl mutants (all Col ecotype).
Project description:The zebrafish runzel (ruz) carries a mutation in the titin gene resulting in muscle degeneration and embryonic lethality. At the onset of the visible phenotype (3-3.5 days post fertilization), RNA expression of the tail and trunk (primarily skeletal muscle) was compared between ruz mutants and wildtype siblings using the Affymetrix Zebrafish Gene Chip. Mutant RNA was matched with RNA of wildtype siblings from the same clutch. 3 separate clutches were used (n=3). RNA was labeled, sheered, and hybridized as in Shephard et al. (Shepard et al., 2005) and the data analyzed as in Choe et al. and Weber et al. (Choe et al., 2005; Weber et al., 2005). Results suggest a novel mechanism of titin muscular dystrophy pathogenesis including upregulation of heat shock proteins. Keywords: disease state analysis
