    Kinase Assay
    [1]

    BxPC3 (human pancreatic adenocarcinoma) or LL/2 (murine lung carcinoma) cells are treated with DMSO or various concentrations of GSK2656157 for 1 hour, followed by addition of 5 μg/mL tunicamycin or 1 μM thapsigargin for an additional 6 hours to induce endoplasmic reticulum-stress. Cells are lysed in cold radioimmunoprecipitation assay (RIPA) buffer [150 mM NaCl, 50 mM Tris-Cl pH 7.5, 0.25% sodium deoxycholate, 1% NP-40, protease inhibitors, and 100 mM sodium orthovanadate]. Clarified lysates are resolved by SDS-PAGE and transferred to nitrocellulose membrane using NuPAGE system. Blots are incubated with antibodies to total PERK, p-eIF-2α Ser51, total eIF-2α, ATF4, and CHOP. IRDye700DX-labeled goat anti-mouse immunoglobulin G (IgG), IRDye800-CW donkey anti-goat IgG, and IRDye800-CW goat anti-rabbit IgG are used as secondary antibodies. Proteins are detected on the Odyssey Infrared Imager.

    Cell Assay
    [1]

    BxPC3 cells are treated with DMSO or 1 μM GSK2656157 for 1 hour before adding 5 μg/mL tunicamycin for an additional hour. Cells are metabolically labeled with 125 μCi 35S-methionine for the subsequent 1 hour. Cells are lysed in cold RIPA buffer and lysates are resolved by SDS-PAGE, followed by exposure to a phosphorimager screen. Control cells are also pretreated with 100 μM cyclohexamide for 1 hour followed by metabolic labeling. Radioisotope incorporation is quantitated using ImageQuant 5.2 software.

    Animal Administration
    [1]

    Exponentially growing HPAC (5×106 cells/mouse), Capan-2 (10×106 cells/mouse), or NCI-H929 (1×6 cells/mouse) cells are implanted subcutaneously into the right flank of 8- to 12-week-old female SCID mice. Similarly, 10×106 BxPC3 cells per mouse are implanted in female nude mice. When the tumors reached approximately 200 mm3 in size, the animals are weighed, and block randomized according to tumor size into treatment groups of 8 mice each. Mice are dosed orally with the formulating vehicle or GSK2656157. Mice are weighed and tumors measured by calipers twice weekly. Tumor volumes are calculated. The percentage of tumor growth inhibition is calculated on each day of tumor measurement using the formula: 100× [1 − (average growth of the compound-treated tumors/average growth of vehicle-treated control tumors)].

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
