| Research Abstract |
We analyzed the association with dbpC/contrin(dbpC) and the character of endometrial cancer stem cells .We designed and constructed a cytomegarovirus vector containing dbpC cDNA, and transfected it into Ishikawa(IK) cells, an endometrial cancer cell line. The expression of ALDH1 was increased in IK-dbpC cells, compared to mock cells,and the ratio of SP cells were more than 10-fold in IK-dbpC cells compared to mock cells . Downreguration of dbpC expression was remarkably reduced the ALDH1 expression and the rate of SP cells, compared to negative control. Microarray analysis showed that one of the cancer/testis antigens was up-regulated in IK-dbpC cells compared with mock cells.
