Fig. 6From: Impaired lysosomal activity mediated autophagic flux disruption by graphite carbon nanofibers induce apoptosis in human lung epithelial cells through oxidative stress and energetic impairmentRepresentative flow cytograms and corresponding fluorescence photomicrographs showing (a) % reduction in acridine orange positive cells (b) reduced Lysotracker red staining (c) reduction in pHrodo dextran green fluorescence (marked with yellow arrows). Scale bar - 50 μm. Per view 50 cells and 4 views per group were analyzed. (d) Immunoblotting and (e) respective densitometry analysis of cytosolic release of cathepsin D in GCNF exposed cells. GAPDH was used as a loading control. Values are expressed as mean ± SE of three independent experiment. *p<0.05 was considered as statistical significantBack to article page
