The proteins were dealt with SDS-PAGE (sodium dodecyl sulfate–polyacrylamide gel electrophoresis) gel, then transferring of membranes was performed. Moreover, membranes were blocked with skim milk and probed using the primary antibody. The following antibodies were used in this study: β-actin (Abcam; ab194697: WB 1:2000), UGT1A1 (Abcam; ab194697: WB 1:2000; IF 1:400), and anti-Estrogen Receptor alpha (ERα) antibody (Abcam; ab32063: WB 1:1000; IF 1:200), respectively. Then the chemiluminescence-based detection was conducted according to the secondary antibody conjugated horseradish peroxidase with exposed film. The assays of co-immunoprecipitation (CO-IP) were immunoprecipitated with Suspension Agarose beads (Protein G Plus/Protein A).

The livers and jejunum tissue were homogenized in ice-cold radio immunoprecipitation assay (RIPA) buffer [50 mM Tris HCl, 1 mM EDTA, 150 mM NaCl, 0.1% sodium dodecyl sulfate, 0.5% sodium deoxycholate, 1.0% Nonidet P-40, and phenylmethane sulfonyl fluoride (PMSF), pH 8.0]. The homogenate was centrifuged at 12,000 rpm for 20 min at 4°C. The supernatants were collected for Western blot analysis, which was performed as described previously (Kong et al., 2015 (link)). The antibodies used in the present study included anti-Mrp-2 (1:500; sc-5770, Santa Cruz; California, USA), anti-glyceraldehyde 3-phosphate dehydrogenase (anti-GAPDH) (1:20,000; YM3029, Immunoway; Texas, USA), anti-UGT1A1 (1:4,000; ab194697, Abcam; Cambs, UK), anti-P glycoprotein (1:1,000; ab170904, Abcam; Cambs, UK), anti-CES2 (1:1,000; DF6433, Affinity; Cambs, UK), and anti-Bcrp (1:200; sc-69988, Santa Cruz; California, USA). The gray intensities of the bands were quantified using ImageJ software (National Institute of Health, MD, USA).

Tissues were fixed with neutral formalin (10%), then dehydrated and embedded with paraffin. Moreover, sections (5 μm) were cut from these tissues; primary antibody of UGT1A1 (Abcam, ab194697, 1:200) and the matched secondary antibody were further used to incubate after antigen retrieval, respectively. Besides, after staining with DAB substrate kit (Pierce, USA), these sections were observed under Olympus microscope to obtain a photograph of the expression status, including subcellular location, expression level, and expression density.

Protein extracted from liver tissue were obtained using Radio Immunoprecipitation Assay (RIPA) lysis buffer (1 mM phenylmethanesulfonyl fluoride, PMSF) according to the manufacturer’s instruction (Beyotime Biotechnology Co. Ltd, China). Protein concentration were measured by the BCA assay kit (ThermoFisher Scientific, Allentown PA). Forty µg of each lysate sample was boiled for 10 min, separated by 12% sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and transferred onto polyvinylidene fluoride (PVDF) membranes (Millipore, Bedford, USA). Nonspecific reactivity was blocked in 5% nonfat dry milk in Tris-buffered saline (0.05% Tween-20) (TBST) for 1h at room temperature. The membranes were incubated overnight with primary antibodies including anti-SULT2A1 (ab194113, Abcam, Cambridge, MA), anti-UGT1A1 (ab194697, Abcam, Cambridge, MA) and β-actin (Jinqiao Technology Co. Ltd, China) followed by reaction with a secondary horseradish peroxidase-conjugated (HRP) anti-rabbit IgG antibody (Jinqiao Technology Co. Ltd, China). Specific bands were detected by use of the ECL Chemiluminescence System (Merck Millipore, USA).

Total cellular protein of liver tissues was extracted by RIPA lysis buffer (150 M of NaCl, 1% Triton X-100, 0.5% deoxycholate, 0.1% SDS, and 50 mM Tris (pH 7.4)) containing protease inhibitors. 20 μg soluble proteins were separated by 8 ~ 12% SDS-PAGE and were transferred onto a nitrocellulose membrane (Pall Corporation, NY, USA). After being blocked with 5% fat free milk, the membranes were incubated with primary antibodies against caspase3 (#9662), cleaved caspase 3 (#9664), CYP1A2 (#14719) (Cell Signaling Technology, MA, USA), CYP1A1 (#ab3568), CYP1B1 (#ab33586), GSTT1 (#ab199337), GSTM1 (#ab113432), UGT1A1 (#ab194697) (Abcam, Cambridge, UK), and β-actin (#60008; Proteintech Group, AL, USA). Immunolabeling was visualized with HRP-conjugated anti-rabbit IgG or anti-mouse IgG (Santa Cruz Biotechnology, CA, USA). The density of the specific bands was quantified using ImageJ software.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
