Abstract | BACKGROUND: METHODS: Expression of the above molecules involved in reverse cholesterol/ lipid transport was assessed in rats 8 weeks after 5/6 nephrectomy (CRF) or sham operation. RESULTS: CRF caused heavy accumulation of neutral lipids, upregulation of SR-AI, LOX-1, LXRalpha/beta, ABCA1 and ABCG1 in the aorta, reduction in LCAT in the plasma and no significant change in either SR-BI or beta-chain ATP synthase in the liver. CONCLUSIONS:
Lipid accumulation despite upregulation of the efflux (LXR, ABCA1, ABCG1) system in the aorta in CRF is largely due to upregulation of influx (SR-AI and LOX-1) pathway and LCAT deficiency.
