E 3A) was paralleled by a 10-fold larger ALDH1A3 protein abundance in LK7 when compared with LK17 pGSCs (Figure 3B,C). Consistently with this of 21 difference, DEAB-sensitive enzymatic activities of your ALDH isoforms have been higher9in LK7 compared with LK17 cells when measured in the presence of CuSO4 (100 nM) below all experimental situations by flow cytometry (Figure 3D,E, black and blue). Notably, κ Opioid Receptor/KOR Inhibitor custom synthesis 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). With each other, these information these information point to a mesenchymal phenotype with the LK7 pGSC but not of LK17 cells. point to a mesenchymal phenotype of the LK7 pGSC but not of LK17 cells.Figure 3.
