Dataset on gene expressions affected by simultaneous knockdown of Hedgehog and Dpp signaling components in embryos of the spider Parasteatoda tepidariorum

Simultaneous, parental RNA interference (pRNAi) mediated knockdown of Hedgehog and Decapentaplegic (Dpp) signaling components, Pt-patched (Pt-ptc) and Pt-dpp, respectively, exhibited serious defects in the formation of the major embryonic axes in the model spider Parasteatoda tepidariorum. This paper describes a dataset of a custom oligonucleotide two-color microarray analysis that was carried out to compare the transcript expression levels between untreated (normal) and Pt-ptc + Pt-dpp double pRNAi embryos at late stage 5. Array spots that showed the intensity ratio of [Pt-ptc + Pt-dpp double pRNAi]/[normal]
