16 VhlF/F, VhlF/FHif-1αF/F, and VhlF/FHif-2αF/F were previously described.16 For temporal hepatocyte-specific disruption, VhlF/F, VhlF/FHif-1αF/F, and VhlF/FHif-2αF/F mice were crossed with mice harboring the Cre-ERT2 recombinase under control of the albumin promoter, SA-Cre-ERT2.17 The mice are a mixed Sv129 and C57BL/6 background, and wild-type littermate control mice were used as a comparison for each experiment. Mice were used between the ages of 6 and 8 weeks for all experiments. For activation of the SA-Cre-ERT2 recombinase for short-term experiments (i.e., 1 and 3 days), mice were treated with
1 dose of tamoxifen (2 mg/mouse in corn oil) by intraperitoneal (IP) injection and killed 24 hours or 3 GSK2118436 clinical trial days after tamoxifen treatment. For the 7-day and 2-week experiments, mice were fed tamoxifen in the diet for 2 days, then replaced with regular chow and killed at 7 days or 2 weeks after initial tamoxifen administration. For the alcohol treatment, mice were treated Palbociclib with tamoxifen by IP injection on 2 consecutive days, then were fed, ad libitum, a 4% alcohol-containing liquid diet (Lieber-DeCarli Diet; Dyets, Inc., Bethlehem, PA) and killed 2 weeks after alcohol administration. Mice were housed in temperature- and light-controlled rooms and were given water and pelleted chow ad libitum. All animal studies were carried out in accordance with guidelines
and approved by the National Cancer Institute and University of Michigan Animal Care and Use Committee. RNA was extracted from tissues, reverse transcribed, and quantitative 上海皓元 real-time reverse-transcriptase polymerase chain reaction (qRT-PCR) was performed using primer sequences listed in Supporting Table 1. Liver whole-cell or nuclear extracts
were prepared. Membranes were incubated with antibodies against HIF-1α, HIF-2α (Novus Biologicals, Littleton, CO), ANGPTL3 (Santa Cruz Biotechnology, Inc., Santa Cruz, CA), and smooth muscle actin (SMA) (Sigma, St. Louis, MO), phophorylated, and total acetyl-CoA carboxylase (ACC) (Cell Signaling Technology, Beverly, MA) signals obtained were normalized to GAPDH (Santa Cruz) for whole cell extract and histone H1 (Santa Cruz), pregnane X receptor (PXR), and hepatic nuclear factor 4 (HNF-4α) (Abcam, Cambridge, MA) for nuclear extracts. Liver cDNAs were hybridized to an Agilent 44 K mouse 60-peptide oligomer microarray (Agilent Technologies, Santa Clara, CA). Data were processed and analyzed by a Genespring GX software package (Agilent Technologies). Hematoxylin and eosin (H&E) and Masson’s trichrome staining were performed on formalin fixed paraffin embedded sections. Oil red O staining was performed on frozen liver sections or adherent hepatoma-derived Hepa-1 cells. For quantification of oil red O in Hepa-1 cells, isopropanol was added to the cells after staining. Absorbance was measured at 510 nm in the isopropanol extracts, and values were normalized to protein content.
