Moreover, Fn14 and CD133 expressions were similar in the BA and control groups (ΔC<sub>T</sub> 2.7 ± 1.3 vs. 1.4 ± 1.6, p = 0.07; and 12.0 ± 3.7 vs. 11.78 ± 2.30, p = 0.88, respectively).
The BA liver samples were divided into mild liver fibrosis group (grade I-IV, BA<sub>a</sub>) and severe liver fibrosis group (grade V-VI, BA<sub>b</sub>) to detect Fn14 protein expression.
