Figure 1. Heat map and volcano plot illustrating the gene expression profiles of short- and long-surviving pancreatic cancer patients. (A) Heat map of illustrating the gene expression profiles. Strongly expressed genes are shown in red, while weakly expressed genes are shone in green. KLF5 expression is higher in three short-surviving patients than in three long-surviving patients. (B) Volcano plot showing differential gene expression (P<0.05, FC>2).
