Curcumin synergistically enhances the efficacy of gemcitabine against gemcitabine-resistant cholangiocarcinoma via the targeting LAT2/glutamine pathway.

Cholangiocarcinoma (CCA) is often diagnosed late, leading to incomplete tumor removal, drug resistance and reduced chemotherapy efficacy. Curcumin has the potential for anti-cancer activity through various therapeutic properties and can improve the efficacy of chemotherapy. We aimed to investigate the synergistic effect of a combination of curcumin and gemcitabine against CCA, targeting the LAT2/glutamine pathway.

Expression of FOXO4 Inhibits Cholangiocarcinoma Cell Proliferation Induction of G/G Arrest.

Background/aim: Forkhead box O4 (FOXO4) has been demonstrated to be a tumor suppressor and proposed as target for treatment of a variety of cancer types. However, the role of FOXO4 in cholangiocarcinoma (CCA), a dangerous cancer of bile-duct epithelium, has rarely been explored.

Materials And Methods: The proliferative rate of CCA cell lines KKU-213B, KKU-055 and KKK-D068 was investigated using the sulforhodamine B (SRB) assay.

An aberrantly spliced isoform of anterior gradient-2, AGR2vH promotes migration and invasion of cholangiocarcinoma cell.

Cholangiocarcinoma (CCA) is a cancer of bile duct, considered to be an incurable and lethal cancer. High mortality rate of CCA patients is underlined by cancer metastasis, an ability of the cancer cells that spread to secondary organs. Recently, we have identified Anterior Gradient-2 (AGR2), from a pair of non-metastatic/metastatic cell lines (KKU-213/KKU-213L5), as a gene that is highly and specifically upregulated in the metastatic cell line.
