Check if the same lab product or an alternative is used in the 5 most similar protocols
Grass carp were obtained from Nanchang Shenlong Fisheries Development (Jiangxi, China) and domesticated in our laboratory. The breeding conditions were described in our previous study (35 (link)). CIK (C. idella kidney) cells and CO (C. idella Overy) cells from Professor Pin Nie (Institute of Hydrobiology, Chinese Academy of Sciences) were applied in the experiments. Both CIK cells and CO cells needed Medium 199 (CORNING, USA), to which was added 10% fetal bovine serum (FBS) and 0.6% penicillin–streptomycin liquid (Beijing Solarbio Science & Technology, China); the mixture was then cultured at 28°C in a cell incubator. In addition, CO cells require 5% CO2.

SKOV3 cells were purchased from American Type Culture Collection (ATCC, Manassas VA). SKOV3 was grown in a 50:50 mixture of MCDB (Sigma Aldrich) and Medium 199 (Corning) media supplemented with 10% fetal bovine serum (FBS) and 100U penicillin/mL-100μg/mL streptomycin. To induce Pgp expression, the native SKOV3 cell line was exposed to increasing concentrations of Cisplatin (up to 1μM) by serial passage over 5–6 weeks to create the SKOV3cis cell line. Cisplatin, paclitaxel, doxorubicin, and zosuquidar were all purchased from SelleckChem (Houston, TX) and stocks prepared in dimethylformamide (Cisplatin) or dimethyl sulfoxide (DMSO). Experiments with zosuquidar (5 μM) included a 30 min pre-incubation before adding doxorubicin.

One- to two-week old pre-weaned Yorkshire pig islets were isolated under procedures approved by the University of California Irvine, Institutional Animal Care and Use Committee. Pancreata were procured and stored in cold HBSS (<1 hour). Pancreata were minced and digested with Collagenase Type V (Sigma-Aldrich) in a 37°C shaking water bath for 15 minutes. The enzymatic digestion was quenched with HBSS supplemented with 1% porcine serum (Gibco-Thermo Fisher Scientific) and digested tissues were filtered through a 500 μm metal mesh. Islets were then cultured in maturation media made up of Ham’s F-12 medium (Corning), HEPES (Sigma-Aldrich), L-glutathione (Sigma-Aldrich), nicotinamide (Sigma-Aldrich), ITS+3 (Sigma-Aldrich), gentamycin sulfate (Corning), Trolox (Sigma-Aldrich), heparin (Sagent Pharmaceuticals), Pefabloc (Santa Cruz Biotechnology), L-glutamine(Alfa Aesar), medium 199 (Corning) and 10% porcine serum.

Check if the same lab product or an alternative is used in the 5 most similar protocols
Experiments were performed in male-derived human brain microvascular endothelial cell line HBEC-5i (American Type Culture Collection-ATCC, CRL 3245). Cells were cultured in 75 cm2 culture flasks that were coated with 0.2% w/v gelatin (porcine Type A; Sigma-Aldrich) before cell seeding. A 1:1 ratio of endothelial growth media (VEC Technologies, Rensselaer, NY, USA) and Medium 199 (Corning, Manassas, VA, USA) was used for cell culture. The VEC media includes serum and antibiotics, while 10% FBS and 1% penicillin-streptomycin were added to the M199. Cells were incubated with ET-1 (1μM) in the presence/absence of ETA receptor antagonist BQ123 (20 μM; cells were treated 30 minutes before ET-1 treatment) for 16 hours. Experimental design is depicted in Figure 1. Dose of ET-1 and BQ123 were selected based on our previous reports (Abdul et al. 2020a (link); Abdul et al. 2020b (link)). BQ123 was dissolved in distilled water and further diluted with working media. Thus, the control group did not receive vehicle treatment. The cell lysate was collected for Western blot analysis and RT-qPCR.

All cell lines were preserved in a humidified incubator at 37°C, 5% CO2 and atmospheric O2. Human cardiac progenitor cells (hCPCs)[60 (link)] and human coronary artery endothelial cells (HCAECs) were used between passages 17-23 and 7-14, respectively. hCPCs were cultured as previously described.[63 (link)] Briefly, cells were cultured in 0.1% porcine gelatin (Sigma-Aldrich) coated flasks in growth media consisting of 10% fetal bovine serum (Thermo Fisher Scientific), 22% EBM2 (Lonza) complemented with EGM2 single quotes (Lonza) in Medium 199 (Corning), 1X non-essential amino acids (Lonza), and 1X penicillin-streptomycin (Life Technologies). HCAECs were grown in MesoEndo cell growth media (Cell Applications).

The cells were maintained within a trigas humidified Heracell 150i incubator (Thermo Scientific, Waltham, MA, USA) at 37 °C and 5% CO2/O2. For experiments to inhibit the mTOR’s kinase activity, the cells were pre-treated with rapamycin (Cell Signaling Technology, Danvers, MA, USA) at a concentration of 100 nM for 24 h prior to stretch.

Isolation and Stimulation of Human Aortic Endothelial Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
HAECs were isolated from aortic explants of heart transplant donors in association with the UCLA Transplant Program. Isolation of HAECs involves selective enzymatic digestion and results in high purity of the ECs as previously described (Navab et al., 1988 (link); Romanoski et al., 2011 (link)). Confluent HAECs in Medium 199 (Corning) supplemented with 1% heat-inactivated fetal bovine serum and 1% antibiotics were treated with Ox-PAPC as described in a previous publication (Romanoski et al., 2010 (link)), 10 ng/ml recombinant human TNF, or 10 ng/ml IL-1β. The dose of Ox-PAPC (40–50 µg/ml) used for these experiments was chosen based on experiments from our laboratory and others showing consistent atherogenic effects at this concentration (Lee et al., 2012 (link)). Although Ox-PAPC can have antiinflammatory action on bacterial products at much lower concentrations (Oskolkova et al., 2010 (link)), aortic extracts of oxidized phospholipid at the concentration used in this study have been shown to have proinflammatory effects on ECs (Subbanagounder et al., 2000 (link); Oskolkova et al., 2010 (link)). For rescue experiments, confluent HAECs were pretreated with 10 µM Stattic (Selleck Chemicals) or vehicle control for 30 min; the cells were then treated with control media or media containing 10 ng/ml TNF or 40 µg/ml Ox-PAPC in the presence or not of the inhibitor for 4 h.

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.
