Curcumin augments gemcitabine cytotoxic effect on pancreatic adenocarcinoma cell lines.

Background And Aim: Gemcitabine, the first-line agent in pancreatic adenocarcinoma, has shown limited clinical benefit. Cyclooxygenase-2 (COX-2) represent one of the most promising targets for cancer prevention and treatment. In this study, we investigated whether the phytochemical curcumin, a natural COX-2 inhibitor, can potentiate gemcitabine effect on survival of human pancreatic cancer cells.

ErbB4 increases the proliferation potential of human lung cancer cells and its blockage can be used as a target for anti-cancer therapy.

Clinical and experimental data suggest that ErbB-4, a member of the epidermal growth factor receptor family, may have a role in cancer progression and response to treatment. We found recently, using a retrospective clinical analysis, that expression of ErbB-4 receptor is correlated with metastatic potential and patient survival in non-small-cell lung cancer (NSCLC). The purpose of this work was to correlate the expression of the ErbB-4 and lung cancer cells growth in vitro and in vivo and to determine the therapeutic potential of a monoclonal antibody to ErbB-4 against lung cancer.
