Experimental Protocol


Oligo-cDNA microarray hybridization was performed according to the National Cancer Institute in-house protocol, as detailed previously (Yamaguchi et al., 2008). Briefly, total RNAs were prepared from cultured fibroblasts using an RNeasy mini kit (Qiagen, Valencia, CA). The quality (purity and integrity) and quantity of each total RNA preparation was measured using a Nanodrop ND-1000 spectrophotometer (Thermo Scientific, Wilmington, DE). A universal human reference RNA (Stratagene, La Jolla, CA) was used as a control. cDNA samples generated from RNA samples and purified before the coupling reaction were labeled with Cy3 (for fibroblast samples) or Cy5 (for reference RNA) mono-reactive dyes (GE Healthcare, Piscataway, NJ), and were hybridized simultaneously on an oligo-DNA chip (Hs-OperonV3.0-v1p24, p27, p31) overnight at 42°C. Two fluorescent intensities of the oligo-DNA chip were scanned using a microarray scanner (GenePix 4000B; Axon Instruments Inc., Molecular Devices Corp., Sunnyvale, CA). Differential gene expression was profiled using Genepix Pro 5.0 software and was analyzed by Miltenyi Biotec (Bergisch Gladbach, Germany).
