Figure 1. Selection of robust biomarkers to establish a prognostic UPS gene signature. (A) The 97 intersections of the OS related genes in MMRF-COMMPASS and GSE2658. (B) The LASSO coefficient profiles of the candidate OS-related UPS genes with nonzero coefficients. (C) A dotted vertical line represents the optimal value of the parameter (lambda) used in the LASSO model. (D) Multivariate Cox regression was used to establish the UPS gene signature, and six genes were finally selected as predictors of OS. (E) The mRNA levels of the 6 identified genes in training set (MMRF-COMMPASS). (F) Coefficient distribution of the gene signature.
