Fig. 4
Expression levels of the six candidate gene biomarkers (a for MX1; b for OASL; c for SPINK1; d for CRK; e for GRAPL; f for RNF2) detected by microarray and quantitative PCR analyses. Each dot displayed the expression levels of the six candidate gene biomarkers in each individual patients (n = 6 for each group in the discovery cohort; n = 16 and 15 for non-responder and responder groups in the validation cohort, respectively)
