Desert Hedgehog Down-regulation Mediates Inhibition of Proliferation by γ-Glutamylcyclotransferase Knockdown in Murine Glioblastoma Stem Cells.

High GGCT expression is important for expression of DHH and activation of the hedgehog pathway, which is required to maintain glioblastoma stem cell proliferation. Therefore, inhibition of GGCT function may be useful in suppressing stemness of glioblastoma stem cells accompanied by activation of the hedgehog pathway.
