Hepatitis E Virus Cell Culture Model

Cell lines used included Huh-7,38 (link) A549/D3,39 and persistently HEV-infected A549 cells40 (link) representing parental A549 cells initially infected with HEV genotype 3c isolate 47832c. These cells were chosen as cell culture model as they maintain viral infection while being passaged or cryopreserved, yielding a stable infection, which avoids establishing an infection at each experiment. This feature is superior to other, hepatocyte-based systems and yields high titers and HEV infection efficiency. Cells were cultivated in Dulbecco’s modified Eagle’s medium (DMEM) (supplemented with 2 mM L-glutamine, 100 μg/mL streptomycin, 100 U/mL penicillin, and 10% v/v fetal bovine serum; FBS.S 0615, Bio & Sell GmbH, Feucht, Germany) at 37°C with 95% relative humidity and 5% CO2.
Treatments with LDL (360-10-0.1; Lee Biosolutions, Maryland Heights, MO), 25-HC (11097; Cayman Chemicals, Ann Arbor, MI) and simvastatin (sc-200829B; Santa Cruz Biotechnology, Heidelberg, Germany) were performed in serum-free DMEM (D6546-500ML; Sigma Aldrich, Schnelldorf, Germany). Fully supplemented DMEM was used for treatment with gemfibrozil, fenofibrate, avasimibe, PSC833, FGF19, and alirocumab. A final concentration of 200 μM leupeptin (L2884-1mg; Sigma-Aldrich, St Louis, MO) over 24 hours was used to inhibit lysosomal degradation.

Culture and Compound Treatment of Human Cell Lines

Check if the same lab product or an alternative is used in the 5 most similar protocols
Human cell lines (RCC4, HeLa, Hep3B, MCF-7 and U2OS) were cultured in DMEM (D6546-500ML; Sigma Aldrich) each supplemented with 10% fetal bovine serum (F7524-500ML; Sigma Aldrich), 2 mM L-glutamine (G7513- 100ML; Sigma Aldrich), 50 units/ml of penicillin, and 50 μg/ml of streptomycin (P0781-100ML; Sigma Aldrich). The RCC4 cell line was a gift from C.H.C.M. Buys (University of Groningen, [2 (link)]), the HeLa and Hep3B cell lines were from the European Collection of Cell Cultures (ECACC) [2 (link)], the MCF-7 cell line was from the American Type Culture Collection (ATCC) and the U2OS cell line was a gift from S.Galey (ICRF Clare Hall Laboratories, United Kingdom). Cells were treated either with DMSO (control) or compounds (dissolved in DMSO) and added directly into the cell culture medium to the desired final concentration for 4–5 h as previously described [9 (link),22 (link)].

Cell Culture Conditions for MCF-7, Hep3B, and U2OS

Check if the same lab product or an alternative is used in the 5 most similar protocols
Human cell lines (MCF-7, Hep3B, and U2OS) were cultured in Dulbecco's modified Eagle's medium (DMEM and D6546–500ML; Sigma) each supplemented with 10% fetal bovine serum (F7524–500ML; Sigma), 2 mml-glutamine (G7513–100ML; Sigma), 50 units/ml penicillin, and 50 μg/ml streptomycin (P0781-100ML; Sigma). The MCF-7 cell line was from the American Type Culture Collection (ATCC); the Hep3B cell line was from the European Collection of Cell Cultures (ECACC) (12 (link)). The U2OS cell line was a gift from S. Galey (ICRF Clare Hall Laboratories, United Kingdom). Cells were treated either with DMSO (control) or compounds (dissolved in DMSO) and added directly into the cell culture medium to the desired final concentration as described previously (27 (link), 35 (link)). For hypoxia (0.5% O2) treatment, cells were seeded at least 24 h prior to being incubated for 16 h in an InvivO2 400 hypoxic workstation (Ruskin Technologies, Bridgend, UK).

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.
