  • a For explanation of treated/control ratio, see Materials and Methods. For data derived from microarray analysis, the expression ratio (treated/control ratio) for each transcript is calculated from the average expression ratios based on multiple measurements. Data from Northern analysis are based on single hybridization experiments.
