Reduced samples were loaded onto NuPAGE Bis-Tris (Thermo Fisher Scientific) gels in MOPS buffer and separated proteins were transferred onto a PVDF membrane for immunodetection with anti-PPARγ (C26H12, 1:2000: Cell Signaling Technologies, Danvers, MA, USA), HSP90α (GTX109753: Gene Tex, Irvine, CA, USA, 1:2000), HDAC1 (GTX100513: Gene Tex, 1:2000), GAPDH (GTX100118: Gene Tex, 1:1000), H3K27ac (39134: Active Motif, Carlsbad, CA, USA, 1:2000), H3K9ac (39918: Active Motif, 1:2000), H3k27me3 (C36B11: Cell Signaling Technologies, 1:2000), and Histone H3 (D2B12: Cell Signaling Technologies, 1:2000) antibodies as primary antibodies, and the HRP-conjugated goat anti-rabbit antibody (#7074: Cell Signaling Technologies, 1:2000) as the secondary antibody.

Hypothalamic Gene and Protein Expression

Check if the same lab product or an alternative is used in the 5 most similar protocols
Peripheral tissues were rapidly dissected, snap frozen, and stored at −80 °C until use. Hypothalamic blocks were micro-dissected from 300 μm coronal brain slices. RNA extraction and qPCR was performed as previously described38 (link) (qPCR primers listed in Supplementary Table S2). For protein extraction, frozen tissues were homogenised in Tissue-Protein Extraction Reagent (Peirce) containing Protease Inhibitor Cocktail (Roche) and 1 mM PMSF. Protein levels were determined by SDS-PAGE and Western blot analysis using anti-PPARγ (C26H12, Cell Signalling, 1:500) and anti-GAPDH (FL-335, Santa Cruz Biotechnology, 1:1000) antibodies.

ChIP-qPCR Analysis of NF-kB and PPAR-γ

Check if the same lab product or an alternative is used in the 5 most similar protocols
ChIP was performed by following the protocol of the EZ-Magna ChIP A/G Chromatin Immunoprecipitation kit (Sigma-Aldrich). AML-12 cells and BMDMs (1 x 107) treated with 40 μM genipin or vehicle for 48 h were fixed with 1 % PFA and then washed by PBS. The cells were collected and subjected to cellular and nuclear lysis. The whole nuclear lysate was sheared by a sonicator with optimal conditions (7 s pulse on, 10 s pulse off, 15 cycles, 40 % amplitude) to yield 200-700 pb DNA. 10 % of sheared lysate was used for the Input. 50 μL of the sheared lysate (the equivalent of 1 x 106 cells) was subject to immunoprecipitation by overnight incubation of either anti-NF-kB p65/RelA antibody (A19653, Abclonal), anti- PPARγ (C26H12, Cell Signaling) or IgG control. The immunoprecipitated DNA and Input DNA were purified and amplified by RT-PCR with primers sets listed above.

Adipogenic Differentiation of Rat MSCs

Check if the same lab product or an alternative is used in the 5 most similar protocols
Mesenchymal stromal cells (MSCs) from 12-week old WT and Cyp2j4−/− rats were obtained as previously described [32] (link). MSCs cells were allowed to grow in Supplemented MesenCult™ MSC Medium (STEMCELL Technologies, UK) for 5 days on Petri dishes (Nunc, ThermoFisher Scientific, UK). MSCs from WT and Cyp2j4−/− rats were differentiated into mature adipocytes by incubation with an adipogenic induction medium (StemPro®,Gibco, UK) for 14 days.
Antibodies used in western blot were: anti-PPAR (C26 H12, Cell Signaling #2435, 1:1000), anti CEBP (Cell Signaling #2295, 1:1000), anti-Phospho-Akt-Ser473 (D9E, Cell Signaling #4060, 1:2000), anti-Phospho-Akt-Thr308 (244F9, Cell Signaling #4056, 1:1000), anti-panAkt (C67E7, Cell Signaling #4691, 1:1000) and anti-β-Actin Antibody (C4, sc-47778, 1:10,000), anti-PPARα (H2, SC-398,394, 1:1000), anti-PPARβ/δ (F-10, SC-74517, 1:1000), anti-FXR (D-3, SC-25309, 1:1000), anti-LXRα (ab2585, 1:1000), and anti-β-Actin Antibody (C4, sc-47778, 1:10,000).

Antibody-based Protein Expression Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
The antibodies used in the present study were as follows: anti-COL1A1 (72026) and anti-PPARγ (C26H12) from Cell Signaling Technologies (Boston, USA); and anti-ITIH4 (ab180139) from Abcam (Cambridge, UK). Secondary antibodies were either goat Alexa 488 (A-11008) or 594 (A-11012) obtained from ThermoFisher (Oxford, UK). Lipopolysaccharide (LPS, L2630) was purchased from Sigma (Steinheim, Germany).

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.
