Comparison of the relative abundances of proteins in VLPs without antigen (MLV Gag) with those of carrying different cancer antigens showed reasonable correlation with Pearson’s correlation coefficients of r = 0.67 (MCAM vs. MLV Gag), 0.70 (TRP1 vs. MLV Gag), 0.74 (MAGEA10 vs. MLV Gag), 0.75 (MART1 vs. MLV Gag) and 0.78 (MAGEA4 vs. MLV Gag) (Fig. 5B). The gene discussed is MCAM; the disease is cancer.
