PLK1 expression is over-expressed in gastric cancer and correlates with survival time. A. Box plots derived from gene expression data in Oncomine comparing expression of PLK1 gene in normal tissue (left plot) and gastric cancer tissue (right plot). Oncomine box plots were retrieved from serous gastric carcinoma and normal tissue. B. Kaplan-Meier survival analysis for the relationship between survival time and PLK1 signature in gastric cancer was performed by using the online tool (http://kmplot.com/analysis/).
