Figure 3. For Hep-2/0 cells which were not transfected with TNF-α gene, no noticeable TNF-α mRNA was seen (Fig. 3 A, band 1).

While in transfected Hep-2/TIC and Hep-2/TNF-α cells, electrophoresis on RT-PCR products revealed specific bands of TNF-α mRNA (Fig. 3B, band 2; Fig. 3C, band 1.). In Hep-2/0 cells which were not transfected with CD gene, no mRNA of CD gene was detected (Fig. 3C, band 2). While in transfected Hep-2/TIC and Hep-2/CD cells, electrophoresis on RT-PCR products revealed specific bands of mRNA of CD gene (Fig. 3B, band 1; Fig. 3C, band 2).
