ABCG1 protein, human

ABCG1 protein is a member of the ATP-binding cassette (ABC) transporter superfamily.
It plays a key role in cellular cholesterol homeostasis and is involved in the regulation of cholesterol efflux from cells.
ABCG1 is expressed in various tissues, including macrophages, and its dysregulation has been implicated in the pathogenesis of cardiovascular and metabolic disorders.
Researchers studying ABCG1 can leverage the power of PubCompare.ai, an AI-driven tool that helps identify the most reproducible and effective research protocols from the literature, preprints, and patents.
This streamlines the research process and takes ABCG1 protein studies to new heights by optimizing the selection of experimental methods.

Cholesterol efflux capacity was quantified in blood samples from the cohort of healthy volunteers as described previously.17 (link) This assay quantifies total efflux mediated by pathways of known relevance in cholesterol efflux from macrophages (i.e., ATP-binding cassette transporter A1 [ABCA1] and G1 [ABCG1], scavenger receptor B1, and aqueous diffusion).17 (link) Each sample was run in triplicate, with a mean coefficient of variation of 4.3%. Values were normalized by dividing the efflux capacity of individual patients by the efflux capacity of a serum pool run with each assay.
Cholesterol efflux capacity in the coronary disease and pharmacologic-study cohorts was quantified with the use of a slightly modified method designed to increase throughput. J774 cells, derived from a murine macrophage cell line, were plated and radiolabeled with 2 μCi of 3H-cholesterol per milliliter. ABCA1 was up-regulated by means of a 6-hour incubation with 0.3 mM 8-(4-chlorophenylthio)-cyclic AMP. Subsequently, efflux mediums containing 2.8% apolipoprotein B–depleted serum were added for 4 hours. All steps were performed in the presence of the acyl–coenzyme A:cholesterol acyltransferase inhibitor CP113,818 (2 μg per milliliter). In a pilot study involving serum samples from 20 healthy volunteers, results from the original assay procedure17 (link) and the modified method were strongly correlated (r = 0.85).
Liquid scintillation counting was used to quantify the efflux of radioactive cholesterol from the cells. The quantity of radioactive cholesterol incorporated into cellular lipids was calculated by means of isopropanol extraction of control wells not exposed to patient serum. Percent efflux was calculated by the following formula: [(microcuries of 3H-cholesterol in mediums containing 2.8% apolipoprotein B–depleted serum – microcuries of 3H-cholesterol in serum-free mediums) ÷ microcuries of 3H-cholesterol in cells extracted before the efflux step] × 100. All assays were performed in duplicate. To correct for interassay variation across plates, a pooled serum control from five healthy volunteers was included on each plate, and values for serum samples from patients were normalized to this pooled value in subsequent analyses. Additional studies that were performed to validate the measurement of cholesterol efflux capacity are described in the Supplementary Appendix.

Cryopyrin−/−, caspase-1−/−, Abca1−/−, Abcg1−/−, Abca1−/−Abcg1−/−, Kir6.1−/−, Kir6.2−/−, and SUR2−/− mice have been described previously (Miki et al., 1998 (link), 2002 (link); Schott et al., 2004 (link); Mariathasan et al., 2006 (link); Stoller et al., 2007 (link); Yvan-Charvet et al., 2008 (link)). P2X7−/− mice were obtained from Lexicon Pharmaceuticals. Mice were housed in a pathogen-free facility. All experiments were conducted in compliance with the National Institutes of Health Guide for the Care and Use of Laboratory Animals and were approved by the Institutional Animal Care and Use Committee at Genentech. BMDMs were prepared as described previously (Lamkanfi et al., 2007 (link)). In brief, BMDMs were isolated from femurs of 6–12-wk-old mice and were cultured in Iscove's modified Dulbecco's medium containing 10% heat-inactivated FBS, 20% L cell–conditioned medium, 100 U/ml penicillin, and 100 mg/ml streptomycin at 37°C in a humidified atmosphere containing 5% CO2. After 5–7 d of incubation, cells were collected and plated in 6- or 24-well plates in Iscove's modified Dulbecco's medium containing 10% heat-inactivated FBS and 100 mg/ml thymidine and antibiotics. Macrophages were cultured for an additional 24 h before use.

Primary peritoneal macrophages were obtained from thioglycollate-treated mice 4 days after injection. For bone marrow-derived macrophages, bone marrow was isolated from femurs and tibias, and differentiated in DMEM supplemented with 20% fetal bovine serum (FBS), 30% L929 conditioned medium and antibiotics for 6–7 days. MEFs were immortalized by the SV40 Large T antigen retrovirus and selected with puromycin. Immortalized bone marrow-derived macrophages were obtained as previously described (Blasi et al., 1985 (link); Gandino and Varesio, 1990 (link)). To reconstitute immortalized bone marrow derived macrophages from LXR-deficient mice with LXR wild-type or mutants, retrovirus supernatants from Phoenix E cells transfected with the expression vectors were infected to immortalized macrophages. The iBMDM stably expressing wild-type LXRα, LXRβ or mutants were obtained by 300 µg/ml of hygromycin B (Invitrogen). For RNAi experiments in macrophages, cells were transfected with control or ON-TARGETplus SMARTpool siRNAs (25 nM, Dharmacon) targeted RXRα, RXRβ, Ubc9, Hdac4, ABCA1, ABCG1 and TRAF6 using Darmafect 4 (Dharmacon). Cells were used for experiments after 48 hr incubation and target gene knockdown was validated by real-time PCR and Western Blot. For macrophage inflammatory responses, cells were placed in DMEM containing 0.5% FBS, 5 μM simvastatin, 100 μM mevalonic acid and 1 μM GW3965 or DMSO overnight. Cells were then stimulated with 10 ng/ml LPS or vehicle. For cellular cholesterol modification, bone marrow-derived macrophages were placed in DMEM containing 0.5% FBS, 5 μM simvastatin plus 100 μM mevalonic acid for 4 hr, then incubated with complexes of randomly methylated cyclodextrin (Trappsol) and cholesterol (Sigma–Aldrich) (CD/Chol, 100 μM) to overload with cholesterol (Klein et al., 1995 (link)) or hydroxypropyl-β-cyclodextrin (Trappsol) (CD, 10 mM) to deplete cholesterol for 1 hr and stimulated with LPS (10 ng/ml) for 4 hr.

RAW264.7 cells were cultured on six-well plates with 10% FBS DMEM at a density of 1.0 × 106 cells/well. When the RAW264.7 cells adhered, they were incubated with or without indicated treatment. After the cells were collected, they were washed twice with ice-cold phosphate-buffered saline (PBS). RIPA lysate and protease inhibitor 100:1 were used to extract the protein, and total protein concentration was calculated using a bicinchoninic acid (BCA) protein assay kit (Thermo Scientific, Waltham, MA, USA). The extracted proteins were separated on an 8% sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) gel at 100 V, and the protein was transferred from the gel to polyvinylidene difluoride (PVDF) membranes (Millipore, Billerica, MA, USA) at 250 mA for 150 min. The blots were then blocked for 1.5 h at room temperature with skimmed milk powder in 5% bovine serum albumin (BSA). The blots were incubated overnight shaker at 4 °C with mouse anti-ABCA1 (1:500, Abcam, Cambridge, MA, USA), rabbit anti-ABCG1 (1:500, Proteintech, Wuhan, China), rabbit anti-SR-BI (1:1000, Sangon Biotech, Shanghai, China), and rabbit anti-GAPDH (1:1000, Sangon Biotech, Shanghai, China).

The quality and quantity of RNA were determined spectrophotometrically at optical density (OD)260 and OD260/OD280 = 1.8–2.1 using a NanoDrop spectrophotometer (Thermo Fisher Scientific, Waltham, MA, USA). For qRT-PCR analyses, 1 μg of total RNA was used with a reverse transcription kit (Roche, Shanghai, China) to obtain cDNA according to the manufacturer’s protocol. The specific primers of the mRNAs for mouse ABCA1, ABCG1, SR-BI, and glyceraldehyde-3-phosphate dehydrogenase (GAPDH) are listed in Table 1. PCR was performed using the following light cycle conditions: 95 °C for 10 min, followed by 40 cycles of 95 °C for 15 s, 56 °C for 30 s. The synthesis of polymerase chain reaction products was monitored by melting curve analysis and agarose gel electrophoresis. The quantitative results for mRNA and circRNA were normalized by glyceraldehyde-3-phosphate dehydrogenase and 18s rRNA, respectively.
