Professor Teh said the study will pave the way for a better understanding of the roles that newly identified genes play in the development of bile duct cancer.
"This discovery adds depth to what we currently know about bile duct cancer," said Teh. "More important is that we are now aware of new genes and their effects on bile duct cancer, and we now need to further examine their biological aspects to determine how they bring about the onset of Cholangiocarcinoma."
Using state of the art DNA sequencing, the researchers analysed eight bile duct cancers and normal tissues from Thai patients, and discovered mutations in 187 genes. The team then selected 15 genes that were frequently mutated for further analysis in an additional 46 cases. Many of these genes, such as MLL3, ROBO2 and GNAS, have not been previously implicated in bile duct cancers.
"With this finding we now know much more about the molecular mechanisms of the disease and we can draw up additional measures that can be taken while we identify the most appropriate treatment protocols. We are talking about the potential to save many lives in Thailand," said Professor Vajarabhongsa Bhudhisawasdi, Director of the Liver Fluke and Cholangiocarcinoma Research Center, Khon Kaen University of Thailand. "Also, this study shows that we can work closely with our counterparts in other countries and share our expertise and experience to improve the lot for the people."
The researchers also compared the bile duct cancers to other related cancers of the liver and pancreas. Surprisingly, they found that the bile ducts cancers shared certain similarities with pancreatic cancer.
"This research provides a strong direction for future studies," said Associate Professor Patrick Tan, faculty member of the Cancer and Stem Cell Biology Programme at the Duke-NUS. "Cholangiocarcinoma and Pancreatic Duct Adenocarcinoma appear to
