Figure 6. Gene expression of CD271 and Nanog in clinical specimens of HPC.

Figure 6

(A) Kaplan-Meier analysis for the relapse-free survival rate according to the CD271 mRNA level, in tumor tissues derived from 28 HPC patients by surgery. Real-time RT-PCR analyses were conducted, normalized to the expression of GAPDH, and the fold-change in CD271 expression levels in the tumor versus normal mucosa was calculated. The cut-off value for the CD271-expression index was 1.5. *Statistically significant. (B) Nanog expression was examined by real-time RT-PCR. Cut-off value for the Nanog expression index was 1.5. *Statistically significant. Closed circles, CD271 high; open circles, CD271 low.
