Research Abstract

Low intermediate molecular weight hyaluronan(HA) triggered epithelial-to-mesenchymal transition(EMT) and enhanced chemoresistance in malignant mesothelioma cells. Additionally, chemosensitivy of mesothelioma cells were resulted in a slight improvement by blocking of HA-CD44 signaling. Subpopulation equipped with cancer stem cells(CSCs)-associated properties were founded in mesothelioma spheroids expressing EMT markers. CSC-like subpopulation showed up-regulation of hyaluronan synthases(HAS) and were suppressed in the presence of hyaluronan synthases inhibitor, 4-methylumbelliferone(4MU). These results suggested that hyaluronan mediated regulation of EMT-and CSCs-properties related with chemoresistance on malignant mesothelioma cells.
