Integration of proteomics data helped in the identification of potential 20q candidates, including HNF4A (hepatocyte nuclear factor 4, alpha), TOMM34 (translocase of outer mitochondrial membrane 34), and SRC (SRC proto-oncogene, nonreceptor tyrosine kinase).5 In another study, integrating metabolomics and transcriptomics yielded molecular perturbations underlying prostate cancer. Here, HNF4A is linked to prostate carcinoma.
