Data for: Microarray data on the comparison of transcript expression between normal and Pt-ptc + Pt-dpp double RNAi embryos in the common house spider Parasteatoda tepidariorum

A custom oligonucleotide, two-color microarray experiment was conducted to detect the differences in the transcript expression levels between untreated (normal) and Pt-patched (Pt-ptc) + Pt-decapentaplegic (Pt-dpp) double RNA interference (RNAi) embryos at late stage 5 in the common house spider Parasteatoda tepidariorum. The array probes were designed based on accumulated EST and cDNA sequences. The microarray dataset has been deposited in the Gene Expression Omnibus (GEO) Database at the National Center for Biotechnology Information (NCBI) under the accession GSE112435. Array spots that showed the intensity ratio of [Pt-ptc + Pt-dpp double RNAi]/[normal] <0.6 were categorized as positive. The expressions of some of the transcripts related to the positive array spots were examined in embryos by whole-mount in situ hybridization.
