E 3A) was paralleled by a 10-fold higher ALDH1A3 protein abundance in LK7 when compared with LK17 pGSCs (Figure 3B,C). Regularly with this of 21 difference, DEAB-sensitive enzymatic activities with the ALDH isoforms had been higher9in LK7 compared with LK17 cells when measured in the presence of CuSO4 (one hundred nM) beneath all experimental conditions by flow cytometry (Figure 3D,E, black and blue). Notably, disulfiram exerted only an incomplete blockage of ALDH activity (Figure 3D,E, red). Collectively, only an incomplete blockage of ALDH activity (Figure 3D,E, red). Collectively, these data these data 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 three.
