Title Temporal expression analysis of C. elegans larvae hatching in the presence and absence of food.
Organism Caenorhabditis elegans
Experiment type Expression profiling by array
Summary When C. elegans larvae hatch in the absence of food they persist in a stress resistant, developmentally arrested state (L1 arrest). We characterized mRNA expression genome-wide in a pair of bifurcating time series starting in the late embryo and proceeding through the hatch in the presence and absence of food (E. coli).
We used Affymetrix C. elegans expression arrays to measure gene expression in 18 total timepoint/conditions in three biological replicates.
Keywords: time course; plus/minus food
Overall design Nematode populations were staged such that they hatched withing a 2.5 hr window, and time point zero (0 hr) corresponds to when 50% of the population had hatched. RNA was isolated with TRIzol and 100 ng was used for T7 RNA polymerase-based mRNA amplification and biotin labeling using MessageAmp II-Biotin Enhanced kit (Ambion). Labeled cRNA was fragmented, hybridized to the Affymetriz array, and scanned according to the manufacturer’s protocol.
