The aggressive cholangiocarcinoma (CCA) representing a liver cancer that overexpresses COX-2 enzyme is aimed to be targeted by COX-2 selective boron carrier, fenbufen boronopinacol (FBPin).
To adapt to hypoxic environment, HIF-1α stimulates COX-2 protein expression and promotes EMT process in hepatocellular cancer cells, which enhances HCC invasion and metastasis, and might contribute to poor prognosis in HCC patients post TACE treatment.
COX-2 -765 C allele genotype, drinking history and family history of liver cancer may increase the susceptibility to hepatitis B-related liver cancer in Gansu province, China.
E2F1 may function as a critical antiapoptotic factor both in human and in rodent liver cancer through its ability to counteract c-Myc-driven apoptosis via activation of PIK3CA/Akt/mTOR and c-Myb/COX-2 pathways.
Because prostaglandins (PGs) and nitric oxide (NO) have been proposed to be involved in angiogenesis in vivo, the production of PGs and NO and the behavior of inducible NO synthase (iNOS), cyclooxygenase 1 (COX-1), and inducible cyclooxygenase (COX-2) were studied in parental drug-sensitive (P5) liver cancer cell lines and in P5-derived MDR1 cells P1(0.5).
