Fig. 3From: Impaired lysosomal activity mediated autophagic flux disruption by graphite carbon nanofibers induce apoptosis in human lung epithelial cells through oxidative stress and energetic impairmentViability reduction and loss of membrane integrity in GCNF exposed A549 cells was assessed using MTT assay (a) and propidium iodide (PI) dye exclusion assay (b), respectively. Values represents mean ± SE of three independent experiment. *p<0.05 was considered as statistical significantBack to article page
