Biological Activity

Description Trastuzumab (anti-human HER2) is a humanized, recombinant monoclonal antibody that binds to the extracellular domain of HER2, MW:145.53 KD.
Targets
HER2 [1]
In vitro

Loss of function of CSK or PTEN confers resistance to both lapatinib and trastuzumab in Human epidermal growth factor receptor 2 (HER2)-amplified gastric cancer (GC) cells.[1]
In vivo

Trastuzumab exerts antitumor effects in ERBB2-positive AFPGC PDX models, in which statistically significant differences are present in the tumor volume between the group treated with AZD5438 combined with trastuzumab and those treated with AZD5438 or trastuzumab alone in ERBB2 and CCNE1 co-amplified PDX models.[2]

Protocol (Only for Reference)

Cell Assay:

  • OE19 cells transduced with CSK targeting sgRNAs or PTEN targeting sgRNAs were used for following test. OE19 cells transduced with non-targeting sgRNA as control. a Growth curve of test groups with 0.05 μM lapatinib in combination with indicated dose of trastuzumab for 6 days.
Animal Study:

  • AnimalModels:Female BALB/c nude mice of ERBB2-positive alpha-fetoprotein producing gastric carcinoma patient-derived xenograft models
    Dosages:10 mg/kg
    Administration:i.p.[2]
