drug basic information
Drug ID:
DB00072 (BTD00098, BIOD00098)
Drug Name:
Trastuzumab
Drug Method:
The expression levels of miRNA were determined by quantitative real-time PCR and those of protein were by Western blot analysis. Luciferase activity assay was used to verify the target genes of miRNAs. MTT assay was used to test the drug-resistant phenotype changes in cancer cells via overregulation of miRNAs.
Drug Response:
resistant
Cancer basic information
Cancer:
breast cancer
Tissue/Cell:
cell line (SKBR3)
Other information
Title:
MicroRNA-21 links epithelial-to-mesenchymal transition and inflammatory signals to confer resistance to neoadjuvant trastuzumab and chemotherapy in HER2-positive breast cancer patients.
