Data are means ± SD of arbitrary units. Statistical analysis was performed using one-way ANOVA and Tukey’s post hoc test. * p < 0.05, ** p < 0.02, *** p < 0.001, and **** p < 0.0001.

Article Snippet: Then, the medium was withdrawn, and the cells were washed twice with PBS before being transfected with CYP7B1 HDR and CYP7B1 CRISPR/Cas9 KO plasmids (Santa Cruz Biotechnology) using lipofectamine 2000 (Thermo Fisher Scientific).

Characterization of a stable human CYP7B1 -knockout HepG2 cell line. ( A ) Levels of oxysterols: 4β-hydroxycholesterol, 25-hydroxycholesterol, and 27-hydroxycholesterol. ( B ) Gene expressions of FASN , IGFBP2 , and PCSK9 normalized to PPIB in wild-type (WT) and CYP7B1 -knockout (KO) HepG2 cells. ( C ) FASN , IGFBP2 , and PCSK9 gene expressions of wild-type HepG2 cells incubated with 250 nM 4β-hydroxycholesterol (4β-HC), 25-hydroxycholesterol (25-HC), or 27-hydroxycholesterol (27-HC) for 24 h. ( D ) Gene expressions of CYP7B1 -KO HepG2 cells incubated with 250 nM 4β-hydroxycholesterol (4β-HC), 25-hydroxycholesterol (25-HC), or 27-hydroxycholesterol (27-HC) for 24 h. Data are shown as individual, means ± SD of four replicates except for 4β-hydroxycholesterol (eight replicates). Statistical analysis was performed using one-way ANOVA and Tukey’s post hoc test or Mann–Whitney’s U test. * p < 0.05 and ** p < 0.02.

Summary of phenotype of Cyp7b1 deficiency in rats. The absence of this enzyme increases levels of 25-HC and through this, broad metabolic control is exerted on FASN, IGFBP2, PCSK9, LDLR, SCD1, ABCA1, and LRP1.
