You please imagine I have differentially expressed proteins for conditions A and B from proteomics. Also marker genes by single cell analysis for conditions A and B. I am seeking for the best way to combine transcriptomics and proteomics. One way could be finding common up and down regulated proteins (genes) as persistent differentially expressed agents. Then, feeding those in pathway analysis. I want to be advised by you for a nice way in combining transcriptomics and proteomics especially the visualization part.
