Upregulation of apoptosis marker gene transcripts in HepG2 cells and primary hepatocytes by APAP-derived exosomes. (a) 13 mRNA transcripts were upregulated by > 1.5-fold in HepG2 cells treated with APAP-derived exosomes compared with untreated cells (n = 4/sample). (b,c) Relative expression of caspase-3, caspase-9, and TNF-α mRNA transcripts in HepG2 cells (b) or primary hepatocytes (c) after 24 h incubation with APAP-derived exosomes (n = 8/sample). Real-time PCR analysis, determined by the comparative Ct method and normalized using the values of control set at 1, indicating significant differences between exosome-treated cells and untreated groups. *P < 0.05.
