TG absorption is not affected in HSLiKO mice. Mice fed chow diet were injected with tyloxapol to inhibit peripheral lipolysis and then gavaged with 100 μl corn oil containing 2 μCi [³H]trioleate. Plasma was collected prior to injection with tyloxapol and 2 and 4 h after gavaging to measure (A) TG concentrations and (B) radioactivity. Four h post-gavaging mice were sacrificed and radioactivity in (C) liver and (D) small intestine were determined by liquid scintillation counting. (E) Distribution of radioactivity in lipid species of jejunum 4 h post-gavaging. Data represent mean values (n = 5–6) ± SEM.
