IHC staining and qRT-PCR confirmed the overexpression of EDIL3 in cancer cells (Figure 5B, C) and revealed that tumors with high EDIL3 exhibited a much lower apoptosis rate by TUNEL assay, whereas PCNA, a proliferative marker, was dominantly positive in EDIL3-overexpressing tumors but only sporadically positive in control tumors (Figure 5D). The gene discussed is EDIL3; the disease is cancer.
