Fig. 5. (A) qPCR and western blot analyses of KLK6, VEGF, and MMP9 expression in gastric cancer and adjacent normal tissues. (B) Immunohistochemical staining of KLK6, VEGF, and MMP9 in gastric cancer and adjacent normal tissues. The a, c, and e are tumor tissues; b, d, and f are normal tissues. (C) Kaplan–Meier curves suggesting that KLK6− patients had a significantly better chance of survival than KLK6+ patients. The χ2 and P-values are indicated in the plot.
qPCR = quantitative polymerase chain reaction; KLK6 = kallikrein 6; VEGF = vascular endothelial growth factor; MMP9 = matrix metallopeptidase 9; mRNA = messenger RNA.
*Indicated value means statistical significance.
