Differential expression of transcripts identified by the microarray analyses was examined using qRT-PCR and immunohistochemistry. Additional colon tumors from five (M; nuclear β-catenin-positive) mice and four (S; nuclear β-catenin-negative) mice were harvested, and qRT-PCR was performed on nine genes that exhibited representative strong or subtle patterns in the microarray analyses. All nine patterns detected in the microarray set were validated by the qRT-PCR results.
