HSG cells were plated at 4 × 105 cells per well in 35-mm plates, and cultured in 2 mL of DMEM/Nutrient Mixture F-12 (DMEM/F-12) with 5% FBS. After 24 h, medium was switched to low-serum medium containing DMEM/F-12 with 0.2% FBS. After a 24 h incubation, cells were treated with the following reagents for an additional 24 h: LDN-212854 (Cat# SML0965, Sigma-Aldrich Corp., The Woodlands, TX, USA) or LDN-193189 (Cat# SML0559, Sigma-Aldrich Corp.), 10 or 60 nM; recombinant human BMP6 (Cat# 507-BP-020, R&D Systems, Minneapolis, MN, USA), 6 or 25 ng/mL; and recombinant human TGF-β1 (Cat# 240-B-002, R&D Systems), 5 ng/mL. For inhibitors studies, BMP6 was added to the medium together with LDN-212854 or LDN-193189, while TGF-β1 was added during the last 45 minutes (min) of this treatment, before cells were harvested. The resuspension medium (DMSO or H2O) was used as the negative control for LDN-212854 or LDN-193189 respectively.

Check if the same lab product or an alternative is used in the 5 most similar protocols
A human liver-derived cell line, HepG2/C3A (CRL-10741, American Type Culture Collection, Manassas, VA), was used for functional studies. Cells were grown in MEM + Glutamax supplemented with 10% fetal calf serum (Life Technologies, Mulgrave, VIC, Australia). Control non-specific siRNA (si.NS) and siRNA specific for GNPAT (si.GNPAT; 10 pmol, GenePharma, Shanghai, China) were transfected into 1×105 HepG2/C3A cells in triplicate with Lipofectamine RNAimax (Life Technolgies) according to the manufacturer’s recommendations for reverse transfection at approximately 30% cell confluency. After 72 hours, RNA was isolated using Trizol (Life Technologies) and reverse transcribed with SuperScript III (Life Technologies). Quantitative PCR (qPCR) was performed on a Viia7 (Life Technologies) using SYBR green master mix (Roche, Castle Hill, NSW, Australia) for GNPAT, HAMP, ID1, and SMAD7, and expression levels were compared to the geometric means of reference genes ACTB and HPRT1 using 2−ΔCT. Primer pairs (Integrated DNA Technologies, Coralville, IA) used for quantitative PCR and GNPAT siRNA oligonucleotide sequences are shown in Table 1. For BMP6 treatment, cells were serum deprived for 6 hours in Opti-mem medium (Life Technologies), before the addition of recombinant human BMP6 (R&D Systems, Minneapolis, MN) (10 ng/mL; 4 hours) followed by harvesting.

HepG2 cells were plated in 12‐well plates and cultured at 37°C in 5% CO2 with Dulbecco's modified Eagle's medium (Gibco) containing 10% heat‐inactivated fetal bovine serum (Gibco) (v/v). The cells were then transfected with siRNA targeting human GNPAT/mouse Gnpat gene or control non‐specific siRNA (30 pmol/well; TransSheep; siRNA sequences were listed in Table S2) at 70% confluence with Lipofectamine 3000 (Invitrogen). Twenty‐four hours after transfection, human recombinant BMP6 (R&D systems) was added to a final concentration of 20 ng/mL and cells were incubated for additional 12 hours. The cells were then collected for RNA extraction and quantitative real‐time PCR detection. Isolation of mouse primary hepatocytes was performed as previously described. 39 The isolated primary hepatocytes from either wild‐type or Hfe−/− mice were cultured in Dulbecco's modified Eagle's medium containing 10% fetal bovine serum. The siRNA transfection and BMP6 treatment steps are comparable with HepG2 cells.

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.
