After applying Pearson analysis, we identified five proteins (out of the 34 intersected DE proteins) positively correlated with the maximum renal angiomyolipoma (p < 0.05), namely, PCSK1N, PMEL, HK1, GOT2 and SPTBN2 (as presented in Supplementary Figures 2B–F). Here, PMEL is linked to kidney angiomyolipoma.
