Blockage of transforming growth factor β receptors prevents progression of pig serum-induced rat liver fibrosis

Figure 3 Expression of exogenous transfected gene assessed by Northern blot, A: Hybridization using ³²P labeled oligo-nucleotide probe which targets T7 promoter; B: Hybridization by using ³²P labeled TβR II cDNA probe; C: Hybridization by using ³²P labeled TβR I cDNA probe; D: β-actin probe used as control. Lane 1: Antisense TβR II group; Lane 2: pcDNA3 con-trol group; Lane 3: Disease control group; Lane 4: Antisense TβR I group.
