For instance, it was found that hsa-mir-142 dominates the gene-miRNA-tumor purity correlation, PCNA dominates both the gene-protein-tumor purity correlation and the miRNA-protein-tumor purity correlation, and CCNB1 dominates the miRNA-protein-tumor purity correlation (details in Table B in S1 Appendix). Here, CCNB1 is linked to neoplasm.
