Down-regulated genes in RPMI 8226 cell samples after arsenic trioxide intervention"

Figure 1

Superposition maps of Cy5- and Cy3-labeled RPMI 8226 cell samples treated with and without arsenic trioxide On one spot, if Cy3 signal was much stronger than Cy5 signal, it showed green (i.e. down-regulation); if Cy5 signal was much stronger than Cy3 signal, it showed red (i.e. up-regulation); if the intensities of Cy3 and Cy5 signals were similar, it showed yellow."

Figure 2

Scatter diagram of Cy5/Cy3 ratios in RPMI 8226 cell samples treated with and without arsenic trioxideX-axis and Y-axis represented the fluorescence intensities of Cy3 and Cy5 respectively. Each point in the scatter diagram represented the hybridization signal of corresponding gene in DNA microarray. The red point meant that the Cy5/Cy3 ratio was within the range of 0.5 to 2.0 (with no significant difference in gene expression). The yellow point meant that the Cy5/Cy3 ratio was beyond the range of 0.5 to 2.0 (with significant difference in gene expression)."
