Comparison of expression levels and knockdown efficiencies for selected TFs common to THP-1 and HepG2 cells. In our previous study, human hepatoma cell line HepG2 was used to construct a Matrix RNAi experimental system for TRN analysis . The Matrix RNAi data for nine TF genes (HNF4G, CEBPD, PPARA, PPARD, PPARG, RARA, RARG, RXRA and RXRB) was used to depict the two types of perturbation networks. (a) Gene expression levels in HepG2 (blue) and THP-1 (red) cells treated with negative control siRNA. (b) Gene expression levels in HepG2 (blue) and THP-1 (red) cells after RNAi knockdown.
