(A) The scatter plot analysis of all data points of three genes ( EPHB3, MASP1 and SST ) by Array CGH ( X axis ) and Q-RT-PCR ( Y axis ) analysis in NSCLC patients. Each dark square, the log2 ratio value of the clone containing one of these genes for one case. The correlation coefficients (r) and P-value are given in the upper left corner of the figure. (B) Comparison of real time PCR analysis of EPHB3, MASP1, or SST between SCCs and ACs. Note that the mean expression levels for selected genes were higher in SCCs compared to ACs. (C) Gene expression levels in Q RT PCR of three genes in three cases seen with amplification at 3q27.1–q27.3 by Array CGH. Each samples are depicted (x-axis) and the fold difference of array CGH was depicted by linear-ratios, and N-value was delineated in real time PCR (y-axis). The heights of the bars represent mean expression level of the indicated genes in each SCC cases.
