Figure 4. Zebularine suppressed
TGFβ2-induced α-SMA expression. A: After TGFβ2
treatment, the α-SMA protein level increased by 3.5 fold in 72
h. However, the α-SMA remained at a low level if treated with
zebularine and TGFβ2 together. B: Densitometry analysis
of three independent western blots shows the quantitation of
α-SMA levels. *p<0.05. The error bar indicates mean±SEM.
