    MCE has not independently confirmed the accuracy of these methods. They are for reference only.

    Cell Proliferation Assay[1]

    Cell Line: NIH-3T3 cells, H1666, H3255, and NCI 1975 cells
    Concentration: 0, 1, 10, 100, 1000, 10000 nM
    Incubation Time:
    Result: Effectively inhibited anchorage-independent proliferation of NIH-3T3 cells ectopically expressing EGFR mutants. Showed inhibition of anchorage independent cell proliferation of various lung cancer cell lines (H1666, H3255, and NCI 1975 cells), with IC50 values of 60 nM, 0.7 nM and 99 nM, respectively.

    Cell Viability Assay[2]

    Cell Line: HKESC-1, HKESC-2, SLMT-1 and EC-1 cell lines
    Concentration:
    Incubation Time: 48 and 72 hours
    Result: Observed over 95% of growth inhibition. The respective IC50 concentrations at 48 hours (HKESC-1=0.078 μM, HKESC-2=0.115 μM, KYSE510=3.182 μM, SLMT-1=4.625 μM and EC-1=1.489 μM) and 72 hours (HKESC-1=0.002 μM, HKESC-2=0.002 μM, KYSE510=1.090 μM, SLMT-1=1.161 μM and EC-1=0.109 μM) were all in lower micro-molar range.

    Concentration: 0, 0.01, and 0.1 μM (HKESC-2 cells), 0, 0.1 and 1 μM (EC-1 cells)
    Incubation Time: 24 and 48 hours
    Result: Reduced the phosphorylation of EGFR and the endogenous expression level of HER2 receptors in ESCC cells. Suppressed AKT phosphorylation in a dose and time dependent manner. Significantly reduced the phosphorylation level of the downstream effectors of the AKT-mTOR axis especially in HKESC-2 cells. Inhibited the two major downstream pathways of the ErbB/HER axis, namely, AKT and MAPK pathways in ESCC cell lines.

    Result: Induced G0/G1 cell cycle arrest in both tested ESCC cell lines in a time and dose dependent manner. In HKESC-2 cells, the percentage of cells in G0/G1 phase was increased from 38.2% to 68.1% at 0.01 μM of afatinib and to 74.7% at 0.1 μM of afatinib, from 24 hours (82.4% G0/G1 arrest at 0.01 μM and 86.2% at 0.1 μM) to 48 hours (from 74.7% to 88.2% for 0.01 μM and 91.0% for 0.1 μM). In EC-1 cells, the percentage of cells arrested in the G0/G1 phase was increased from 59.1% to 66.6% and 72.2% at 24 and 48 hours respectively.

Induced regression of large tumors in this HER2-driven model, effectively controlled xenograft tumor formation by the NCIH1975 cell line, expressing EGFR L858R/T790M, with a T/C value of 12% for doses of 20 mg/kg. Induced more than 50% percent tumor reduction after a 4-week treatment period. Downregulated EGFR, HER2 and HER3 phosphorylation.
    Animal Model: Six weeks old female athymic nude mice (nu/nu) (16-20 g)[2]
    Dosage: 15 mg/kg
    Administration: Oral gavage in a schedule of 5 days on plus 2 days off, for two weeks

    • 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.
