Figure 5. Transfection efficiency detection. (A) q-PCR analysis of the transfection efficiency of siRNA-SLC2A1, TXNIP overexpression plasmids, and ATF3 overexpression plasmids. (B–E) Western blot analysis of the transfection efficiency of siRNA-SLC2A1, TXNIP overexpression plasmids, and ATF3 overexpression plasmids. The bar graphs show the mean ± SD of at least three independent experiments (n = 3). **P < 0.01, compared to the Control group, the difference is extremely significant.
