In our study, results showed that PINK1 had significant correlations with tumor purity in both LIHC and LUSC (LIHC: P = 4.21e-02; LUSC: P = 7.24e-07), which indicating their comparative enrichment in tumor cells and may be attributable to the enrichment patterns of PINK1 in the tumor microenvironment. Here, PINK1 is linked to neoplasm.
