Research Abstract

Indirect co-culture of pancreatic cancer cells with PSCs enhanced the spheroid-forming ability of cancer cells and induced the expression of cancer stem cell-related genes ABCG2, Nestin and LIN28. In addition, co-injection of PSCs enhanced tumorigenicity of pancreatic cancer cells in vivo. These results suggested a novel role of PSCs as a part of the cancer stem cell niche. miR-210 was identified as an upregulated micro RNA by co-culture with PSCs. Inhibition of miR-210 expression decreased stem cell-like phenotypes in pancreatic cancer cells. Olmesartan, an angiotensin II type I receptor blocker, administrated at 10 mg/kg in drinking water inhibited the growth of subcutaneous tumors derived from the co-injection of pancreatic cancer cells and stellate cells. Olmesartan inhibited the growth of tumors by targeting stellate cell activities, and olmesartan might be useful as an anti-fibrosis therapy in pancreatic cancer.
