Regulation of activin receptor-interacting protein 2 expression in mouse hepatoma Hepa1-6 cells and its relationship with collagen type IV

Figure 4 ARIP2-overexpression suppressed the expressions of collagen IV mRNA in Hepal-6 cells. lane 1 and 2: Hepal-6 cells were transfected with empty vector pcDNA3 (0.3 μg); lane 3: pcDNA3-ARIP2 (0.1 μg) + pcDNA3 (0.2 μg); lane 4: d pcDNA3-ARIP2 (0.3 μg). The cells were incubated in the absence (lane 1) or the presence of activin A (5 ng/mL) (lane 2, 3 and 4) for 24 h.
