GADD45𝛽 Determines Chemoresistance and Invasive Growth of Side Population Cells of Human Embryonic Carcinoma

Figure 5

Gene expression profile of SP cells according to a microarray and real-time PCR analysis. (a and b) Scatter plot analyses of gene expression in SP versus non-SP cells from NEC8 (a) and MCF7 (b). ABCG2 is shown by the green arrow, and GADD45$\beta$ is shown by the gray arrow. (c and d) Quantitative gene expression analysis of ABCG2 and GADD45$\beta$ (normalized to GAPDH) using real-time PCR in NEC8 (c) and MCF7 (d). Values are the mean ± SD ($n=8$). $P^{*}<.05$ versus non-SP cells.
