Our results showed that the tumor volumes of EC-agrnfl/fl and EC-agrn+/+ mice represented by the bioluminescent photon intensities were not significantly different at day 14 after implantation, but there was a significant tumor growth in EC-agrnfl/fl mice comparing day 5 and 14 after implantation (Figure 4B). The gene discussed is AGRN; the disease is neoplasm.
