Animals were grown on fresh 8P plates (Wormbook.org) until gravid. Eggs were collected by bleaching and hatched in M9 buffer overnight. L1 animals were fed on fresh food for 2 hours at room temperature, harvested and separated from worm debris using a 25μm mesh. RNA was isolated using a standard Trizol protocol. RNA preps were stored at -80C. Quality of RNA preps was first estimated using Agilent 2100 Bioanalyzer. RNA was then reverse-transcribed using the Genisphere Array 350 kit, which generate tagged cDNA. Resulted products are hybridized to the microarrays. Four independent high quality RNA preps (RIN>=7) were chosen for microarray assay using long oligomer-based spotted microarray (Washington University, St. Louis, MO). For dye-swap controls, we ran a technical replicate hybridization for each pair of samples in which the dyes are reversed. Gene spots with “found/good” signals (defined by ScanArray, channel flag 3) in all scans were chosen for gene expression analysis.
