Mass spectrometry-based serum peptide profiling in hepatocellular carcinoma with bone metastasis

Figure 1 Profiles of peptides with m/z of 1780. 7 and 1866.5. A, C: The profiles of peptides 1780.7 and 1866.5, respectively. X-axis, molecular mass (m/z); y-axis, intensity; the green line represents the bone metastasis hepatocellular carcinoma (HCC) group and the red line represents the HCC group; B, D: The mean variance figures for (A) and (C). X-axis: Groups; y-axis: Intensity.

Figure 2 Mass spectrometry spectra and mass spectrometry/mass spectrometry spectra of peptide with an m/z of 1780. 7.

Figure 3 Receiver operating characteristic curve. Receiver operating characteristic (ROC) analysis was performed to evaluate the diagnostic power of the model. The area under the ROC curve value was 0.911.
