FFAR4 and neoplasm: When GPR120 KO bone marrow cells were injected into GPR120 KO recipient mice, feeding the ω-3 diet compared to the ω-6 diet did not reduce tumor growth and final tumor volume (220.6 ± 66.7 mm3 in ω-6 diet versus 259.3 ± 79.7 mm3 in ω-3 diet) and tumor weight (0.43 ± 0.15 g in ω-6 diet versus 0.48 ± 0.12 g in ω-3 diet) (Fig. 1E, F).
