Fig. 3: MALDI-MSI discriminative proteomic signatures of LSCC in comparison to RSCC.

ROC analysis identified differences in proteomic signatures between LSCC (left-panel) and RSCC (right-panel). A Original H&E images of tissues. B Increased intensity distribution of m/z corresponding to ATP2A2 in RSCC compared to LSCC. C Increased m/z values corresponding to EEF1A1 in LSCC compared to RSCC shown in the third row. Scale bars represent 6 mm.
