Targeting Jun N-terminal kinase phosphorylation: A human-derived hepatoprotective peptide human liver transplantation peptide 1 attenuates hepatic ischemia-reperfusion injury

Figure 1 Human liver transplantation peptides expression profile. A: Schematic diagram of liver specimens sent to liquid chromatography-tandem mass spectrometry before and after transplantation in liver transplant patients; B: The heat map indicates the peptide profiles with significant differences between the indicated groups; C: The number of upregulation and downregulation differentially expressed endogenous peptides from liver transplant patients compared with pretransplant; D: This volcano plot represents the distribution of upregulation and downregulation peptides; E-G: Distribution of the length, molecular weight and isoelectric point of peptides; H: Correlation between molecular weight and isoelectric point distribution of peptides. MW: Molecular weight; pI: Isoelectric point; LC/MS-MS: Liquid chromatography-tandem mass spectrometry.
