THP‐1 cells were differentiated as described in Figure 2, & then loaded with unlabeled cholesterol for 24 h. Cells were treated with or without 6‐dihydroparadol (6‐DP, 30 μm) for 24 h & incubated for another 3 h with or without the proteasome inhibitor lactacystin (10 μm), the lysosomal inhibitor chloroquine (100 μm), or the calpain inhibitor calpeptin (30 μg mL−1). The ABCA1 protein levels were detected by Western blot analysis. The bar graphs represent mean ± SD from three independent experiments. *p < 0.05, **p < 0.01, & ***p < 0.001 versus control; n.s., not significant versus control (determined by Student's t‐test or ANOVA with Bonferroni's post hoc test).

Western Blot: ABCA1 Antibody - BSA Free [NB400-105] - Functional miR-33 responsive elements in the 3′UTR of ATP8B1 & ABCB11A,B. Conserved sequences in the 3′UTR of ATP8B1 & ABCB11 are partially complementary to miR-33. The element in human ATP8B1 is located 1877–1897 nt after the stop codon. The element in ABCB11 overlaps the stop codon in primates, while rodents show a conserved sequence 732–751 nt after the stop codon.C,D. Luciferase assays in HEK293 cells using the whole 3′UTR of human or murine ATP8B1 & ABCB11, or a single copy of the responsive elements (RE) identified above, or mutant responsive elements (RE*; where AATGCA was mutated to GGGTTG to prevent complementarity to the seed sequence of the miRNA), co-transfected with (closed bars) or without (open bars) a vector to overexpress miR-33. In grey, data from empty (negative control) & R33 (positive control containing a 100% match to miR-33) reporter vectors.E,F. Relative mRNA expression of canalicular transporters in primary murine hepatocytes (n = 4 dishes/condition) & human HuH-7 hepatoma cells (n = 3 dishes/condition) transduced 48 h with empty or miR-33 adenovirus.G. Relative protein levels in HuH7 cells transduced with empty or miR-33 adenovirus. Some cells were incubated for 16 h in the presence of FXR:RXR agonists (2 µmol/L GW4064 : 1 µmol/L 9-cis-retinoic acid) to induce ABCB11. Asterisk indicates a non-specific band.

Western Blot: ABCA1 Antibody - BSA Free [NB400-105] - (A) Chemical structure, (B) cytotoxicity of alpha-asarone, (C) enhancement of cholesterol efflux by alpha-asarone, (D & E) upregulation of ABCA1 & ABCG1 by alpha-asarone & beta-asarone, & (F) elevation of retinoid X receptor (RXR) alpha transcription. J774A.1 murine macrophages were exposed to 50 μg/ml oxidized low-density lipoprotein (LDL) & treated with 1–10 μM purple Perilla frutescens extracts (PPE)-alpha -asarone & 5–10 μM beta-asarone. (B) MTT assay was performed for the measurement of alpha-asarone toxicity. Graph data represent 1 of 4 independent experiments with multiple estimations. Values are expressed as the percentage cell survival relative to the untreated control cells (cell viability, 100%). (C) Cholesterol efflux was expressed as the percentage fluorescence in the medium relative to total fluorescence. (D & E) For the measurement of ABCA1 & ABCG1 expression, total cell lysates were subjected to western blot analysis with a primary antibody against ABCG1 or ABCG1. beta-actin was used as an internal control. Bar graphs (means ± SEM, n=3) represent quantitative densitometric results of the upper bands. Bar graphs denoted without a common letter indicate significant difference, P<0.05. (F) RXR alpha mRNA expression was measured by RT-PCR. GAPDH was used as a housekeeping gene for the co-amplification with RXR alpha.

Western Blot: ABCA1 Antibody - BSA Free [NB400-105] - Gas6 treatment enhances expression of LXR alpha & LXR beta & their target genes in BMDM.Mouse BMDM were stimulated with 400 ng/ml Gas6, 1 μM T0901317, 10 ng/ml interferon (IFN)-gamma, 10 ng/ml IL-4, or 100 ng/ml LPS for 4 h (a,b) or 400 ng/ml Gas6 for the indicated times (c–g). (a,b,e) The amounts of the LXR alpha, LXR beta, ABCA1, ABCG1, ApoE, AIM, Arg2, VEGF, YM1, & Arg1 mRNAs were analyzed by real-time PCR & normalized to that of Hprt mRNA. (c,d,f,g) The relative abundances of LXR alpha, LXR beta, ABCA1, ABCG1, ApoE, Aim, Arg2, & VEGF proteins were determined by Western blotting analysis.
