SGSM2 and neoplasm: SGSM2 expression was observed more often in early cycles in tumour tissues (red lines) than in normal tissues (green lines) (Figure 1(b)), and the average SGSM2 copy number in paired tumour tissues was 2-fold higher than that in paired normal tissues (Figure 1(c), bar 2 vs. bar 1 = 213.2 vs. 108.3; **P = 0.002).
