293T human embryonic kidney cells were cultured in IMDM (Life Technologies Corporation) containing 10% FBS (Hyclone Defined FBS, Thermo Fisher Scientific), 100 U/mL penicillin and 10 μg/mL streptomycin (Life Technologies Corporation). The following human cell lines were cultured in RPMI (Life Technologies Corporation) containing 10% FBS (Atlanta Biologicals, Lawrenceville, GA): IM-9 (EBV-transformed B lymphoblastoid); U266, KMS-11, RPMI 8226, MM.1S (multiple myeloma); Jurkat (acute T cell leukemia); MOLT-4 and CCRF-CEM (acute T-lymphoblastic leukemia); and Z-138 and REC-1 (mantle cell lymphoma) cell lines. KMS-11 cells were a kind gift from Dr. Lawrence Boise (Emory University, Atlanta, GA). All other cell lines were purchased from ATCC (Manassas, VA). TfR1 expression on the surface of these cell lines has been previously shown for IM-9 and U266 [30 (link), 34 (link)], KMS-11 [33 (link)], and Jurkat [30 (link)]. Expression on the surface of the other cell lines is shown in Supplementary Figure 1.

Quantitative RT-PCR Analysis of Pluripotent Stem Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
ESCs were maintained on gelatin-coated tissue culture dishes in GMEM (Gibco) supplemented with non-essential amino acids (NEAA, ThermoFisher Scientific), sodium pyruvate, GlutaMAX™, 50 μM β-mercaptoethanol (all from ThermoFisher Scientific), 10% fetal bovine serum (FBS, HyClone™ Defined FBS) and 10 ng/ml LIF. RNA isolation and quantitative RT-PCR (qRT-PCR) from ESCs were performed as previously described [44 (link)]. Primer details can be found in Table 3. Relative initial mRNA concentrations were estimated by curve fitting, and normalized to Ppia housekeeping gene mRNA levels in each sample.

An established breast adenocarcinoma cell line, MCF-7 (ATCC, HTB-22™), and an established pancreatic adenocarcinoma cells line, PANC-1 (ATCC, CRL-1469™), were used throughout this study. All cell lines were purchased from the American Type Culture Collection (ATCC, Manassas, VA) as a frozen vial and maintained as described in the technical bulletins in a 37°C cell culture incubator with 5% CO2. Cells were maintained in the recommended basal medium supplemented with 10% defined fetal bovine serum (FBS) and 1% v/v 100X antibiotics/antimycotics (Ab/Am). Cells were tested for mycoplasma contamination using a commercial mycoplasma PCR detection kit (ATCC) and confirmed to be free of mycoplasma contamination following all experimental procedures. Eagle's Minimum Essential Medium (EMEM) and Dulbecco's Modified Eagle's Medium (DMEM) were obtained from ATCC. Hyclone defined FBS and Gibco 100X Ab/Am, a cocktail of 10,000 U/mL penicillin, 10,000 μg/mL streptomycin, and 25 μg/mL amphotericin B, were obtained from Thermo Fisher Scientific (Waltham, MA).

Six day old monocyte-derived dendritic cells were plated in 96-well plates at 2 × 105 cells in 200 µL RPMI-1640 media supplemented with 10% defined Hyclone FBS (Thermo Scientific) and stimulated with a 1:2 dilution of control TCM or pyrazinib (P3) treated TCM from OAC tumour explants or 0.1% DMSO or 10 µM pyrazinib (P3) for 4–5 h before exposure to 10 µg/mL of ultra-pure TLR4 agonist Escherichia coli lipopolysaccharide (LPS-EB; Invivogen) overnight, incubating at 37 °C, 5% CO2. Supernatants were harvested and snap frozen, and cells were assessed for expression of surface markers.

Freshly generated DCs were plated in 96-well plates at 2 × 105 cells in 200 μL RPMI-1640 media supplemented with 10% defined Hyclone FBS (Thermo Fisher Scientific) and stimulated with a 1:2 dilution of conditioned media, or matched background media controls, for 4–5 h before exposure to 10 μg ml-1 of ultrapure TLR4 agonist Escherichia coli lipopolysaccharide (LPS-EB; Invivogen) overnight. Supernatants were harvested and frozen for ELISA analysis, and cells were assessed for expression of surface markers by flow cytometry as we described previously (Supplementary Fig. 1 A) [18 (link), 20 (link), 39 (link)–41 (link)].

Human monocyte-derived immature dendritic cells were generated from peripheral blood mononuclear cells (PBMCs) obtained from buffy coat preparations (National Blood Centre, St. James’s Hospital, Dublin) by density gradient centrifugation (Lymphoprep) as described43 (link),48 (link). Briefly, monocytes were isolated by positive selection using anti-CD14 magnetic microbeads, as described by the manufacturer (Miltenyi Biotec) and seeded at a density of 1 × 106 cells/mL in 6-well plates in 3 mL of Roswell Park Memorial Institute (RPMI)-1640 medium (Gibco) containing 10% defined HyClone FBS (Thermo Scientific), 1% penicillin/streptomycin (Lonza, Basel, Switzerland), 1% fungizone (Sigma-Aldrich), human granulocyte macrophage colony-stimulating factor (GM-CSF, 50 ng/mL; Immunotools, Germany), and human IL-4 (70 ng/mL; Immunotools) in a humidified atmosphere with 5% CO2 at 37 °C. Cells were fed at day 3 by replacing half the medium with fresh cytokine-supplemented RPMI. At day 6, cells exhibited a CD11c+ immature dendritic cell phenotype.

Human monocyte-derived immature DCs were generated from peripheral blood mononuclear cells (PBMCs) obtained from buffy coat preparations (National Blood Centre, St. James’s Hospital, Dublin) by density gradient centrifugation (Lymphoprep) as described [29 (link), 30 (link)]. Briefly, monocytes were isolated by positive selection using anti-CD14 magnetic microbeads as described by the manufacturer (Miltenyi Biotec) and seeded at a density of 1 × 106 cells/ml in 6-well plates in 3 ml of RPMI-1640 medium containing 10% defined HyClone FBS (Thermo Scientific), 1% penicillin/streptomycin, 1% fungizone, human granulocyte macrophage colony-stimulating factor (50 ng/ml; Immunotools), and human IL-4 (70 ng/ml; Immunotools) in a humidified atmosphere with 5% CO2 at 37 °C. Cells were fed at day 3 by replacing half the medium made up with fresh cytokines. At day 6, CD11c+ cells exhibited an immature DC phenotype, as confirmed by ability to upregulate maturation markers following LPS stimulation.

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.
