With 50 /mL of TLE and 100 nM selenium (positive handle) for 24 h
With 50 /mL of TLE and one hundred nM selenium (positive manage) for 24 h followed by five mM glutamate for 18 h. Moreover, chloroquine (lysosome inhibitor) was utilized as a optimistic handle for autophagic flux [41]. Figure 7a exhibits that the manage group showed no LC3 puncta formation, whereas glutamate therapy promoted the LC3 puncta formation, which was related to that of 50 chloroquine (CQ) treatment (the autophagy control group). Noticeably, the pretreatment cells with TLE showed no LC3 puncta staining to cells, indicating the inhibition of autophagy (Figure 7a). On top of that, Pearson’s correlation coefficient was calculated. The co-localization occurred within the glutamate remedy group and autophagy manage group (CQ), and was substantially suppressed by TLE treatment (Figure 7b). To demonstrate when the glutamate induced mitochondria dysfunction, the mitochondrial morphology was investigated (Figure 7c). Glutamate remedy led to mitochondrial fragmentation as well as significantly increased the number of cells with fragmented mitochondria (Figure 7d). Having said that, pre-treatment of 50 /mL TLE decreased the number of cells with fragmented mitochondria and prevented the glutamate-induced mitochondrial fragmentation, showing a regular morphology of mitochondria (tubular and round types), the exact same as the cell control. Therefore, our benefits indicate that glutamate could induce the overaccumulation of ROS, to additional activate the excessive mitophagy procedure, leading to neuronal cell death. Taken collectively, these findings suggest that TLE offers neuroprotection by inhibiting the mitophagy signal.Antioxidants 2021, ten, x1678 PEER Evaluation Antioxidants 2021, ten, FOR14 of 28 13 ofFigure 6.
