Overexpression of the LIPC-E97G variant promotes peripheral cholesterol uptake. A and C, Decay of plasma 3H activity (glycerol tri[3H]oleate, hydrolysable; A) and plasma 14C activity ([14C]cholesteryl oleate, nonhydrolysable) levels (C) in APOE*3.Leiden.CETP mice overexpressing AAV-TBG-eGFP, AAV-TBG-LIPC, and AAV-TBG-LIPC-E97G injected with very-low-density lipoprotein (VLDL)–like particles. B and D, Decay of plasma 3H activity (glycerol tri[3H]oleate, hydrolysable; B) and plasma 14C activity ([14C]cholesteryl oleate, nonhydrolysable) levels (D) in APOE*3.Leiden.CETP mice14 overexpressing AAV-TBG-eGFP, AAV-TBG-LIPC, and AAV3-TBG-LIPC-E97G injected with radiolabeled murine VLDL. E, Liver 14C activity (cholesteryl ester, nonhydrolysable; left) and liver 3H activity (triolein, hydrolysable) levels (right) in APOE*3.Leiden.CETP mice overexpressing AAV-TBG-eGFP, AAV-TBG-LIPC, and AAV-TBG-LIPC-E97G injected with VLDL-like particles. F, Liver 14C activity (cholesteryl ester, nonhydrolysable; left) and liver 3H activity (triolein, hydrolysable levels (right) in APOE*3.Leiden.CETP mice overexpressing AAV-TBG-eGFP, AAV-TBG-LIPC, and AAV-TBG-LIPC-E97G injected with radiolabeled murine VLDL. G and I, Tissue 14C activity (cholesteryl ester, nonhydrolysable; G) and 3H activity (triolein, hydrolysable; I) levels in APOE*3.Leiden.CETP mice overexpressing AAV-TBG-eGFP, AAV-TBG-LIPC, and AAV-TBG-LIPC-E97G injected with VLDL-like particles. H and J, Tissue 14C activity (cholesteryl ester, nonhydrolysable; H) and 3H activity (triolein, hydrolysable; J) levels in APOE*3.Leiden.CETP mice overexpressing AAV-TBG-eGFP, AAV-TBG-LIPC, and AAV-TBG-LIPC-E97G injected with radiolabeled murine VLDL. n=8 per group. A 1-way ANOVA with Tukey correction for multiple comparisons was used for statistical analysis, with a P value cutoff at P<0.05. gWAT indicates gonadal white adipose tissue; iBAT, interscapular brown adipose tissue; sBAT, subscapular brown adipose tissue; and sWAT, subcutaneous white adipose tissue; and TGRL‚ triglyceride-rich lipoprotein. *P<0.05, human wild-type (LIPC-WT) vs LIPC-E97G. $P<0.05, enhanced green fluorescent protein (eGFP) vs LIPC-WT. #P<0.05, eGFP vs LIPC-E97G.
