¹ If one gene had multiple probe sets, the one with highest % P was used.
² Gene expression data was normalized “per chip” in Genespring 7.0, which is normalized to the median expression level of all the genes on the chip. Data is expressed as mean ± standard deviation.
³ N/A, the expression is not shown because % P < 80%.
