The expression level of RegIV as determined by ELISA was lower in the tumor derived from cells overexpressing miR-24 than the tumor derived from control cells (1.77 ± 0.15 ng/ml in SGC-7901/RV-miR-24 vs. 3.13 ± 0.25 ng/ml in SGC-7901/RV-miR-control) (Figure 5F; P < 0.05). The gene discussed is REG4; the disease is neoplasm.
