g mice inside a C57BL/6 background overexpress the H-ApoD gene beneath the handle of the neuron-specific Thy-1 promoter [135]. All experiments had been carried out on 12 month old males.
Primary hepatocytes have been isolated by in situ liver perfusion and collagenase digestion as previously described [44]. Briefly, mice were anaesthetized by intraperitoneal injection of pentobarbital along with the portal vein was cannulated. The liver was then perfused with perfusion buffer (ten mM HEPES, 142mM NaCl, 6,7mM KCl; pH 7,85) containing 0,6mM EGTA and 1,5 U/ mL heparin and subsequently digested with 30 000U collagenase type I (Worthington) dissolved in 150 mL of perfusion buffer containing five mM calcium. Hepatic cells had been gently released in the Glisson capsule and incubated for 1h at space temperature with 5X Wash resolution consisting of DMEM/F12 (Life technologies, Gibco) with 10% fetal bovine serum (Life technologies, Gibco), 500 U/mL penicillin, 500 g/mL streptomycin and 1,25 g/mL Fungizone (Life Technologies) by an orbital shaker. 1×106 cells had been seeded on collagen-pretreated plates (Corning Costar) in DMEM/F12 media containing 10% FBS, 100 U/mL penicillin and 100 g/mL streptomycin. The subsequent day, culture media was removed and renewed with serum-free DMEM/F12 containing the identical antibiotics. The cells were starved for 48h before the 
experiments.
The human hepatocarcinoma cells (HepG2) had been cultured in Eagle’s Minimum Necessary Medium (EMEM) supplemented with 10% FBS. Cells had been then transfected using a UAS-Luciferase construct (a luciferase reporter plasmid containing 5 PPAR response elements) in mixture using a human myc-tag apoD cDNA construct [43] (or an empty vector) within the presence or not of Gal4-PPAR (containing the PPAR cDNA plus the DNA binding domain of GAL4) working with Fugene HD transfection reagent. 48h soon after the transfection, cells have been incubated for 4h with 7M of AA bound to BSA at a mole ratio AA:BSA 4:1. Cells have been then harvested and cellular extracts have been prepared for luciferase [45] and -galactosidase assays (Invitrogen).
Tissues were collected, frozen in dry ice and kept at -80 till further use. Total RNA was extracted using the TRIZOL reagent in line with the manufacturer instructions. Total RNA was then reverse transcribed employing Transcriptor Initial Strand cDNA Synthesis Kit and amplified having a Taq DNA polymerase and precise primers (S1 Table). HPRT was applied as manage.
Tissues or cultured cells had been homogenized in cold lysis buffer (50 mM TrisCl pH 7.three, 150 mM NaCl, five mM EDTA, 0.2% Triton X-100, 2 mM sodium orthovanadate and 10% Full protease inhibitor). Lysates were then incubated 30 min at 4, cleared by centrifugation and stored at 0 until further use. According to Bradford assay [46], 50 g of protein of every single sample were separated on SDS-PAGE and transferred onto PVDF membranes. Following blocking with 5% milk, 1h at space temperature, the membranes had been incubated using the primary 35807-85-3 antibodies overnight at 4. Dilutions with the primary antibodies had been: 1:1000 for PPAR (C26H12), 1:1000 for total AMPK antibody; 1:1000 for phospho-AMPK (Thr172) (40H9) antibody; 1:1000 for ACC antibody; 1:300 for anti-phospho-ACC (Ser79) antibody; 1:5000 for Plin2 antibody, 1:10000 for H-apoD antibody [43], 1: 1000 for the mouse apoD (m-apoD) antibody, 1:10000 for HPRT antibody and 1:100000 for -actin antibody. Main antibodies were then detected using a goat anti-rabbit horseradish perioxidase-conjugated secondary antibody (1:10000) and visualized by chemiluminescen
