a A 10-min treatment of vehicle, BA mixture or CDX in CRL1601/NPC1L1-3×Myc-EGFP cells transfected with pCMV-LIMA1-mCherry. Scale bar, 10 μm. The relative intensity of LIMA1-mCherry (b) and cholesterol (c) resided in ERC in (a) was quantified. Values were presented as mean ± SD (n = 3 independent trials, 100 cells/trial). Two-way ANOVA with Tukey post hoc test, ***P < 0.001. ns, no significance. d Control or Ntcp knockdown CRL1601/NPC1L1-3×Myc-EGFP cells with a 10-min incubation of vehicle, indicated BAs. Scale bar, 10 μm. The relative intensity of cholesterol (e) and LIMA1-mCherry (f) resided in ERC in (d) was quantified. Values were presented as mean ± SD (n = 3 independent trials, 100 cells/trial). Two-way ANOVA with Tukey post hoc test, ***P < 0.001. ns, no significance. g CRL1601/NPC1L1-3×Myc-EGFP cells were transfected with pCMV-LIMA1-FLAG for 48 h and subjected to the co-immunoprecipitation by the anti-FLAG agarose after a 10-min treatment of indicated BAs or 3% CDX (n = 2).
