Phytosterol-mediated inhibition of intestinal cholesterol absorption in mice is independent of liver X receptor
[Scope] Previous studies have proposed that phytosterols activate liver X receptors (LXR) in the intestine, thereby reducing intestinal cholesterol absorption and promoting fecal cholesterol excretion.[Methods and results] In the present study, we examined the effects of dietary phytosterol supplementation on intestinal cholesterol absorption and fecal neutral sterol excretion in LXRαÎČâdeficient mice, and wildâtype mice treated with synthetic highâaffinity LXRαÎČ agonists. LXRαÎČ deficiency led to an induction of intestinal cholesterol absorption and liver cholesterol accumulation. Phytosterol feeding resulted in an approximately 40% reduction of intestinal cholesterol absorption both in wildâtype and LXRαÎČâdeficient mice, reduced dietary cholesterol accumulation in liver and promoted the excretion of fecal cholesterolâderived compounds. Furthermore, phytosterols produced additive inhibitory effects on cholesterol absorption in mice treated with LXRαÎČ agonists.[Conclusions] Our data confirm the effect of LXR in regulating intestinal cholesterol absorption and demonstrate that the cholesterolâlowering effects of phytosterols occur in an LXRâindependent manner.This work was partly funded by the Ministerio de Sanidady Consumo, Instituto de Salud Carlos III, and FEDER âUnamanera de hacer Europa,â grants FIS 14â01648 (to F.B.-V.) andFIS 16â00139 (to J.C.E.-G.), grant FJCI-2014-20689 from theMinisterio de Econom Ìıa, Industria y Competitividad (to I.A.L.)and grant 12/C/2015 from La Fundaci Ìo la Marato TV3 (to F.B-V).
