Bone marrow phenotype determines genetic resistance to RadLV-induced leukemia in radiation chimeric mice

Prolongation of survival in retrovirally induced T cell lymphoma by dietary omega 6 fatty acid

C57BL/Ka mice were fed diets rich in omega 3 or omega 6 polyunsaturated fatty acids and inoculated with the thymic lymphoma-inducing retrovirus RadLV. Mice receiving the omega 3 diet died significantly sooner than those receiving the omega 6 diet. Of the three known mechanisms by which fatty acids can exert antiviral activity, namely, modification of membrane fluidity, modulation of immune response, and synthesis of metabolites with antiviral activity, the first two can be eliminated in the model under study. It is therefore concluded that differences in survival are due to fatty acid metabolites with distinct antiviral activities.
