  1. The \( {\omega}_{mRNA}^{K_1/{k}_2} \) signature was highly enriched for genes in the FXR/RXR Activation pathway according to IPA. This pathway regulates lipid and bile acid metabolism and has been associated with the initiation and progression of liver cancer. The top upstream regulators of \( {\omega}_{mRNA}^{K_1/{k}_2} \) are the nuclear receptors HNF1A, HNF4A and FXR that are known regulators of membrane transport function and have also been associated with liver cancer
