The tumor doubling time of mice treated with EGFR siRNA LPX + UTMC (2.8±0.2 days) was significantly longer than that for sham mice (2.2±0.1 days) or mice receiving NC siRNA LPX + UTMC (2.2±0.1 days) (p<0.05 ANOVA; Student's t-test p<0.05 for EGFR siRNA LPX + UTMC vs. control groups). The gene discussed is EGFR; the disease is neoplasm.
