Figure 1

Effect of Parp-1 deficiency on gene expression. Gene expression data from microarray analyses are plotted for Parp-1^-/-versus wild-type (Parp-1^+/+) ES cell lines (A) & (B). Horizontal and vertical axes represent expression levels normalized for an individual gene. Each point represents normalized expression data for an individual gene. The genes that showed standard deviation greater than 2.0 in the normalized data of both genotypes (A) were excluded and gene lists were constructed with p < 0.05 (B). Fig. 1D–F in the original article [1] remains unchanged and is presented as (C) – (E), respectively.
