Research Abstract |
In the present study, by using animal model of opisthorchiasis-associated cholangiocarcinoma(CCA) and the analysis of CCA tumor tissues of the patients from epidemic areas in Thailand, the genes and signaling pathways to involve in the tumorigenesis, and the biomarkers correlated with stage, metastasis and survival were identified. The study revealed the molecular mechanism that chronic inflammation caused by Opisthorchis viverrini infection decreases the ability of detoxination, leading to the accumulation of ROS and the toxin products from worm, which causes DNA damage, epigenesis and methylation, and expression change of the genes that promotes cell proliferation, differentiation, transformation and carcinogenesis.
