E 3A) was paralleled by a 10-fold greater ALDH1A3 protein abundance in LK7 when compared with LK17 pGSCs (Figure 3B,C). Regularly with this of 21 distinction, DEAB-sensitive enzymatic activities on the ALDH isoforms were higher9in LK7 compared with LK17 cells when measured within the presence of CuSO4 (one hundred nM) under all experimental circumstances by flow cytometry (Figure 3D,E, black and blue). Notably, disulfiram exerted only an incomplete blockage of ALDH activity (Figure 3D,E, red). With each other, only an incomplete blockage of ALDH activity (Figure 3D,E, red). Together, these information these data point to a mesenchymal phenotype of the LK7 pGSC but not of LK17 cells. point to a mesenchymal phenotype of the LK7 pGSC but not of LK17 cells.Figure 3.
