D apoptosis, but not necrosis, in BxPC-3 cells (60 ) and MIA PaCa-2 (30 )

D apoptosis, but not necrosis, in BxPC-3 cells (60 ) and MIA PaCa-2 (30 ) cells (Figure 3B,E). We also observed alterations inside the expression of proteins involved in apoptosis: decreased expression of Bcl-xl and increased expression of cleaved caspase-3 in both cell lines (Figure 3C,F). Additionally, the accumulation of LC3 proteins (Figure 3C,F) and autophagosomes detected via TEM in MIA PaCa-2 cells confirmed that autophagic flux was inhibited by CQ (Figure 3G).Molecules 2021, 26,modifications in apoptosis in either cell line, whereas PT combined with CQ substantially elevated apoptosis, but not necrosis, in BxPC-3 cells (60 ) and MIA PaCa-2 (30 ) cells (Figure 3B,E). We also observed alterations inside the expression of proteins involved in apoptosis: decreased expression of Bcl-xl and enhanced expression of cleaved caspase-3 in each cell lines (Figure 3C,F). Additionally, the accumulation of LC3 proteins (Figure 3C,F) and six of 18 autophagosomes detected by means of TEM in MIA PaCa-2 cells confirmed that autophagic flux was inhibited by CQ (Figure 3G).Figure two.
