ALA deficiency has been found in patients on long-term gastric tube-feeding that included large amounts of skim milk without ALA supplementation. These patients, who were in nursing homes,

^Monounsaturated fatty acids (MONOs) also suppress VCAM1 mRNA, but to a lesser degree than does DHA. AA also suppresses to a lesser extent than DHA.

cEicosapentachoic acid has no effect by itself but enhances the effect of docosahexachoic acid (DHA) dMONOs also induce acyl-CoA oxidase mRNA
