NSCLC Cell Lines and Compounds

Check if the same lab product or an alternative is used in the 5 most similar protocols
NSCLC 201T, 273T and 128-88T cell lines were established in our laboratory as previously described [27 (link)]. A549 and H23 cell lines were purchased from American Type Culture Collection (ATCC; Manassas, VA). Cells were cultured in either BME +10% FBS or RPMI 1640 +10% FBS (ATCC; Manassas, VA). Cell lines were authenticated by genotyping with a multiplex STR assay (Genetica) within 3 months of performed studies. E2 and fulvestrant were purchased from Sigma-Aldrich (St. Louis, MO) and diluted in DMSO to 100mM or 5μM stocks, respectively for in vitro use. AZD4547 was purchased from ChemieTek (Indianapolis, IN) and diluted in DMSO to a 10mM stock for in vitro studies.

NSG (NOD.Cg-Prkdcscid Il2rgtm1Wjl/SzJ) mice (obtained from the Jackson Laboratories), were maintained as a breeding colony. All experiments were conducted under Augusta University IACUC approved protocols. Female, 6–8 week old mice were used in all xenograft experiments. Mice were engrafted with 1–2 × 106 cells via tail vein injection. All mice were treated with either drug, or vehicle control (PEG300:acetic buffer = 1:1), orally using a gavage needle once per day. All treatments were performed 5 days per week for 4 weeks.
Ponatinib was provided by Ariad Pharmaceuticals Inc. (Cambridge, MA). PD173074 was purchased from Cayman Chemical, AZD4547 and BGJ398 from ChemieTek, JNJ-42756493 from Active Biochem and TKI258 from LC Laboratories. E3810 was provided by EOS pharmaceuticals. All drugs were dissolved in DMSO and stored at −80°C before use. For drug treatments, cells were seeded at 3,000–10,000 cells/well, depending on the cell line, in 96-well plates and incubated overnight. Cells were then treated with either DMSO (control) or different FGFR inhibitors as indicated in the results section at concentrations defined by the experiments. Cell viability was determined using CellTiter-Glo® luminescence cell viability kits (Promega) and a SpectraMax® M5e (Molecular Probes) luminescence plate reader as described previously.8 (link)

Transgenic Osteoblast and Chondrocyte Cell Lines

Check if the same lab product or an alternative is used in the 5 most similar protocols
All general laboratory reagents were purchased from Sigma Chemical Co. (Poole, UK) unless otherwise stated. All cells were cultured in α–MEM containing 10% batch-tested FCS (Lonza, Slough, UK), antibiotics (penicillin 50U/ml, streptomycin 50μg/ml) and L-glutamine (5mM). The tetracycline-inducible osteoblastic AT9.2 and chondroblastic DT12.4 cell lines were cultured as previously described19 (link),26 (link) in the presence of 10 μg/ml (AT9.2) or 1μg/ml (DT12.4) tetracycline to inhibit transgene expression, and c-Fos was induced following withdrawal of tetracycline for 48h. DT8.6 cells represent a subclone of ATDC5 chondrocytes constitutively overexpressing c-Fos26 (link) and P1.15, P1.7, 131 P cells are clonal osteosarcoma cell lines derived from c-Fos murine transgenic osteosarcomas12 (link). Primary mouse osteoblasts were obtained from newborn mouse calvariae as described19 (link) and MG63 human osteosarcoma cells were purchased from American Type Culture Collection (ATCC). All cell lines were mycoplasma-negative. Recombinant FGF2 was purchased from R&D Systems (Abingdon, UK). Transfections were performed using Effectene (Qiagen, Crawley, UK) and clones were selected in gentamycin (G418). Lentiviral shRNA vectors for FGFR1 were obtained from MISSION shRNA (Sigma). The FGFR inhibitor AZD4547 was purchased from ChemieTek (Indianapolis, IN).

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.
