Genes selected from the microarray data for further analysis.

*Robust Multiarray Averaging.#Fold-change in expression was calculated by converting the expression values to linear scale, averaging gene expression in each group and taking ratio of expression in non-permissive to permissive groups.*稳健多阵列平均（Robust Multiarray Averaging）：基因表达倍数变化的计算方法为：将表达值转换为线性尺度，对每组的基因表达量取平均值，再计算非允许组与允许组的表达量比值。
