Figure 6. GPR27 is downregulated in gastric cancer clinical samples and correlated with longer survival in gastric cancer patients. (A) Immunohistochemical staining of normal and gastric cancer tissues with anti-GPR27 antibody. (B) Quantitative analysis of GPR27 staining shows significantly H-score in gastric tumor samples compared with adjacent normal tissues (83 normal tissues and 97 tumor samples). (C) Gastric cancer patients with GPR27 over-expression displayed less favorable overall survival than those with low GPR27 expression.
