The liver is an immunologically tolerant organ and a common metastatic site of multiple cancer *** a role for cancer cell invasion programs has been well characterized,whether and how liver-intrinsic factors drive metastatic spread is incompletely ***,we show that aberrantly activated hepatocyte-intrinsic cell cycle-related kinase(CCRK)signaling in chronic liver diseases is critical for cancer metastasis by reprogramming an immunosuppressive *** an inducible liverspecific transgenic model,we found that CCRK overexpression dramatically increased both B16F10 melanoma and MC38 colorectal cancer(CRC)metastasis to the liver,which was highly infiltrated by polymorphonuclear-myeloid-derived suppressor cells(PMNMDSCs)and lacking natural killer T(NKT)*** of PMN-MDSCs in CCRK transgenic mice restored NKT cell levels and their interferon gamma production and reduced liver metastasis to 2.7% and 0.7%(metastatic tumor weights)in the melanoma and CRC models,***,CCRK activated nuclear factor-kappa B(NF-κB)signaling to increase the PMN-MDSC trafficking chemokine C-X-C motif ligand 1(CXCL1),which was positively correlated with liver-infiltrating PMN-MDSC levels in CCRK transgenic ***,CRC liver metastasis patients exhibited hyperaaivation of hepatic CCRK/NF-κB/CXCL1 signaling,which was associated with accumulation of PMN-MDSCs and paucity of NKT cells compared to healthy liver transplantation *** summary,this study demonstrates that immunosuppressive reprogramming by hepatic CCRK signaling undermines antimetastatic *** findings offer new mechanistic insights and therapeutic targets for liver metastasis intervention.
