| Research Abstract |
To clarify underlying molecular mechanism of acyclic retinoid’ s effect to prevent recurrence of hepatocellular carcinoma in patients after surgical removal of the primary tumors, we investigated target proteins of acyclic retinoid responsible for its selective prevention of the cancer. Using precipitation assay with acyclic retinoid-conjugated affinity beads and analyses by next-generation sequencing, we identified PRDX4 and eIF5A, and MAT2A and CTH as promising binding and target proteins, respectively. W e made antibodies recognizing the phosphorylated nuclear receptor, RXRx which was selectively detected in hepatocellular carcinoma. Using these antibodies, we succeeded to observe specific signals in liver cancer tissues.
