Identification and comparison of differentially expressed proteins (DEP) identified from different supervised analysis. Heat maps of fifteen differentially expressed genes that were selected by following supervised analysis A) Normal vs. Cirrhosis, B) Normal vs. HCC, and C) Cirrhosis vs. HCC. The columns represent the samples and the rows represent the proteins. Protein expression is depicted with a pseudocolor scale (−2 to 2); red denoting high expression level and green denoting low expression level. D) Venn Diagram comparing the significantly differentially expressed proteins identified from following comparisons i) Normal vs. Cirrhosis, ii) Normal vs. HCC, and iii) Cirrhosis vs. HCC.
