Expression of PLA2G2A in gastric cancer and its relationship with survival. (a) Histogram of PLA2G2A expression levels in 89 gastric cancer tissues. (b) Kaplan–Meier plot of survival in 88 gastric cancer patients expressing high or low levels of PLA2G2A. (c) Relationship of PLA2G2A expression with tumor stage. The difference is significant by χ2 test (P = 0.002). (d) Correlation between the PLA2G2A expression levels measured by DNA microarray hybridization and quantitative RT-PCR.
