When irradiated GPR120 WT mice were injected with GPR120 WT bone marrow, the ω-3 diet compared with the ω-6 diet significantly inhibited tumor growth and final tumor volume (514.8 ± 88.6 mm3 in ω-6 diet versus 168.4 ± 26.5 mm3 in ω-3 diet, p = 0.0007) and decreased final tumor weight (0.77 ± 0.13 g in ω-6 diet versus 0.31 ± 0.05 g in ω-3 diet, p = 0.002) (Fig. 1B, F). The gene discussed is FFAR4; the disease is neoplasm.
