The significant stimulating effect of the abovementioned DS variants on the cFLIP content in the breast cancer cells after three hours of incubation was also confirmed by the immunofluorescence data (Figure 3C,D and Figure 4C,D), although the alterations in this parameter were less pronounced than those observed in the Western blotting analysis, especially in the case of the BT-474 cells (Figure 3B versus Figure 3D). Here, CFLAR is linked to breast cancer.
