In addition, we previously reported that TRPM7 enhances GSC stemness by regulating the established GSC marker ALDH1 and promotes the induction of ALDH1 activity in glioma cells [2]; therefore, we further tested the relationship between FOSL1 and GSC stemness markers TRPM7 and ALDH1 by IHC assay. The gene discussed is ALDH1A1; the disease is central nervous system cancer.
