TCF21 and neoplasm: We used qRT-PCR to estimate the endogenous mRNA levels of POD-1, SHP, and LRH-1 in HepG2 and H295R tumor cell lines and in a human tumor adrenocortical cell culture, ACC-T36 cells, using qRT-PCR (Figure 1). POD-1 was significantly higher in H295R and HepG2 cells (by 1.73 ± 0.27- and 2.8 ± 0.79-fold, resp).
