| Research Abstract |
Tumorigenesis and proliferation in breast canecr stem cell population; CD44+CD24- cells were higher than those in CD44+CD24+ cells. Hedgehog inhibitor treatment significantly abrogated these increases. Invasiveness, colony formation, and expressions of Shh and Gli1 in CD24 siRNA transfected cells were significantly higher than those in control. Shh suppression in CD24 siRNA transfected cells significantly reduced tumorigenesis and proliferation.
ERa pathway plays an important role for Hh signaling activation, suggesting that ER pathway contributes to the progression in breast cancer.
