Human pancreatic cancer cells (MIA PaCa-2, Panc-1, SW1990, Capan-1, AsPC-1, HPAF-II, Capan-2), were obtained from either the European Collection of Cell Cultures or the ATCC. They were authenticated using either Promega GenePrint10 System or Promega PowerPlex 16HS kit and were grown in DMEM with 10% FBS (GIBCO). Murine pancreatic cancer cells K8484, DT8082, TB31456, TB32048 were previously established from KRasG12D; p53R172H; Pdx1-Cre mice and were grown in DMEM with 10% FBS(23 (link)). KPCFT79653 was from a KrasG12D; Trp53R270H; Brca2Tr/Δ11; Pdx-Cre (KPCB) mouse(24 (link)). All cell lines were grown up to a maximum of 20 passages and for fewer than 6 months following resuscitation. They were routinely verified to be mycoplasma-free using the Mycoprobe Mycoplasma Detection Kit (R&D Systems). Gemcitabine hydrochloride (Tocris), AZD6738 (AstraZeneca), were dissolved in DMSO, kept at -20°C, and used within 3 months. Final DMSO concentrations (0.2%) were kept constant in all experiments. Yoyo-3 (Life Technologies) was used at a final concentration of 0.1 mM.

Mouse PDAC cell line K8484 (established in-house from a KPC tumor) and human PDAC cell line MiaPaca2 (from the European Collection of Cell Cultures, UK, in 2009 (authenticated by STR genotyping)) were treated with AZD2014 +/- Gemcitabine for 96h. Cell viability was determined by measuring total protein content using the sulforhodamine B assay. Combenefit software was used to analyze the data for potential synergy (http://www.cruk.cam.ac.uk/research-groups/jodrell-group/combenefit).

Lectins Effect on Cell Growth

Check if the same lab product or an alternative is used in the 5 most similar protocols
The effect of lectins on cell growth was determined in a primary human umbilical vein endothelial cells (HUVECs), a mouse fibroblast cell line (L929; Passage No. 40), and in a panel of human tumor cells including lung adenocarcinoma (A549; Passage No. 37), acute monocytic leukemia cell line (THP-1; Passage No. 16) and pancreatic adenocarcinoma (PANC-1; Passage No. 29), Human pancreatic ductal adenocarcinoma cell line (CFPAC-1; Passage No.25), Human pancreatic epithelial carcinoma cell line (MIA PaCa-2; Passage No.19) and cervix adenocarcinoma (HeLa) obtained from the European Collection of Cell Cultures (ECCC, Salisbury, UK). HUVECs were maintained in M200 Media supplemented with 50X LVES (Gibco, Invitrogen); THP-1 was maintained in RPMI 1640; L929, A-549, PANC-1, CFPAC-1 and MIA PaCa-2 cells were maintained in Dulbecco’s Modified Eagle Medium (DMEM). HeLa and macrophages were cultured in Eagle's Minimum Essential Medium (EMEM). All media used were supplemented with 10% fetal bovine serum (FBS; Gibco) and the cells were maintained at 37°C and 5% CO2 in a humidified atmosphere.

C26 (murine colon adenocarcinoma 26 cell line) and Miapaca2 (human pancreas cancer cell line) were obtained from a cell line collection of Otsuka Pharmaceutical Co., Ltd. Caki2 (human Caucasian kidney carcinoma cell line) was purchased from the European Collection of Cell Cultures. T24 (human bladder cancer cell line) was supplied by the Cell Resource Center for Biomedical Research, Institute of Development, Aging and Cancer at Tohoku University. Miapaca2 and T24 were genetically authenticated using STR analysis (Promega, October 2012). C26 cells were maintained in RPMI1640, T24 and Caki2 cells in McCoy's 5A, and Miapaca2 cells in D-MEM/Ham's F-12 with 10% fetal bovine serum (FBS), 50 U/mL of penicillin, and 50 µg/mL of streptomycin (a penicillin/streptomycin mixture) in a humidified atmosphere containing 5% CO2 at 37°C.

The human pancreatic cell-line MIAPaCa-2 was obtained from the European Collection of Cell Cultures (ECACC, UK). BxPC-3 and PANC-1 human pancreatic cancer cell lines were obtained from the American Type Culture Collection (ATCC, Rockville, MD, USA). PIN-127 cells were derived in-house from a patient-derived xenograft model as previously described (21) (link).
PANC-1 and MIAPaCa-2 cells were grown in DMEM (Sigma-Aldrich, Dublin, Ireland) supplemented with 5% (v/v) fetal bovine serum (FBS) (Thermo Fischer Scientific, UK) and 2% L-glutamine. BxPC-3 cells were grown in RPMI-1640 medium supplemented with 5% (v/v) FBS. PIN-127 cells were cultured in DMEM/F-12 Hams medium supplemented with 10% (v/v) FBS (Corning, SA). Cells were grown in a humidified atmosphere with 5% CO 2 at 37℃ in culture flasks. Cells were sub-cultured, using PBS to wash and trypsin-EDTA (Bio-Sciences Ltd, Ireland) to detach when cells reached 80-90% confluency.

The cell lines MCF7, A549, ALT, PANC-1, MIA-PaCa-2 (European Collection of Cell Cultures) and WI38 (American Type Culture Collection) were maintained in monolayer culture in 75 cm2 flasks (TPP, Switzerland) under a humidified 5 % CO2 atmosphere at 37°C. For the A549 cell line, Dulbecco's MEM medium (GIBCO 21969, Invitrogen, UK) supplemented with L-glutamine (2 mM, GIBCO 25030, Invitrogen, UK), essential amino acids (1 %, GIBCO 11140, Invitrogen, UK), and foetal calf serum (10 %, S1810, Biosera, UK) was used. For MIA-Pa-Ca-2 and PANC-1, Dulbecco's MEM, supplemented with L-glutamine (2 mM) and foetal calf serum (10 %) was used.
The medium MEM (M2279, Sigma, UK) with added L-glutamine (2 mM), essential amino acids (1 %) and foetal calf serum (10 %) was used for the MCF7, ALT and WI38 cell lines. To passage the cells, they were washed with PBS (GIBCO 14040, Invitrogen, UK), treated with trypsine (GIBCO 25300, Invitrogen, UK), and re-seeded into fresh medium, resulting in an initial cell density of approximately 1x10 4 cells/mL medium. Cells were counted using a Neubauer haemocytometer (Assistant, Germany) by microscopy or a MacsQuant flow cytometer (Miltenyi Biotech, Germany) on a suspension of cells obtained by washing with PBS, trypsinisation, centrifugation at 8 °C at 8000 rpm for 3 minutes, and re-suspension in fresh medium.

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.
