Hidden variable dynamic modeling screening of upregulated genes. Model predicted profile (red) and experimental expression profile (black) of typical genes representing two classes of model prediction (class 1 and class 2). (a) Class 1 genes with good model score (M < 100) and high sensitivity P value (sensitivity Z score > 2; for example LRMP). (b) Class 1 genes with atypical expression profiles (for example, p53TG1); this profile occurs because of a low predicted degradation rate. (c,d) Two class 2 genes with low model score (M > 100) but high sensitivity P value (sensitivity Z score > 2; for example, TNFSF10 and IER3).
