Levels of mRNAs encoding by apoptosis-related factors and STAT3 target genes. A: Bcl-2, BCL-xl, Bim, and Bax mRNAs. B: Socs3, Fga, Fgb, and Fgg mRNAs. Data were from liver samples collected 24h after APAP treatment. The mRNA levels were measured by Q-PCR and normalized by 18S rRNA. Messenger RNA levels in vehicle-treated control mice were arbitrarily set as 1 and results were expressed as mean ± SD (n=5; *p<0.05; **p<0.01; ***p<0.001; ns, not significant).
