Predominant mucosal IL-8 mRNA expression in non-cagA Thais is risk for gastric cancer

Figure 1 Mean interleukine-8 mRNA expression level measurement of relative quantitation by real-time reverse transcription-polymerase chain reaction study in gastric cancer comparing with non-cancer population both Japanese and Thais. In Japanese and Thais, gastric mucosal interleukine-8 (IL-8) mRNA expression in cancer is higher than in non-cancer with P = 0.05. The mean level of IL-8 mRNA expressions in Thai cancer and Japanese cancer were 9615.65 (log₁₀ = 2.62) and 1509.11 (log₁₀ = 2.17), respectively, P = 0.014. The mean level of IL-8 mRNA expression in non-cancer Thais is 2262 (log₁₀ = 1.49) while that in non-cancer Japanese is 10.79 (log₁₀ = 0.69), P < 0.001.
