The molecular mechanisms underlined these aggressive phenotypes were explored.</p><p><strong><span style="text-decoration: underline;">Results:</span></strong> All CCA cell lines cultured in HG medium had significantly higher proliferation rates, and migration abilities than those cultured in NG medium.  The high glucose condition also enhanced invasion ability of KKU-M213, KKU-M214 and KKU-M214L5; but not KKU-M055.  Reducing glucose concentration in the medium to NG could decrease the proliferation rate of all CCA cell lines.  suggesting that CCA growth can be reduced if the glucose concentration is controlled.</p><p><strong><span style="text-decoration: underline;">Conclusion</span></strong><span style="text-decoration: underline;">:</span> High glucose condition plays significant role in promoting aggressive phenotypes of CCA cell lines.  Adjusting glucose concentration to normal condition could decrease proliferation rate of CCA. These results suggest that the progression of CCA may be controlled via controlling blood glucose level in CCA patients with DM.</p> ER -
