Biological Activity

Description Osimertinib mesylate (AZD9291) is the mesylate form of osimertinib, which is an oral, third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) drug.
Targets
EGFR [1]
In vitro

Osimertinib-resistant lung adenocarcinoma (LUAD) cells express higher level of METTL7B in comparison to Osimertinib-sensitive cells. Knock-down of METTL7B by GNC-siRNA re-sensitized LUAD cells to osimertinib.[1]
In vivo

METTL7B is significantly increased in both mRNA and protein level in osimertinib -resistant xenografts as compared with those in osimertinib-sensitive xenografts. In LUAD CDX mouse model, combination treatment with GNC-siMETTL7B (6 mg siRNA per mouse equivalent) significantly suppresses tumor growth as compared with treatment of osimertinib (30 mg/kg) alone.

Protocol (from reference)

Cell Assay:

[1]
  • Cell lines

    lung adenocarcinoma (LUAD) cell lines

  • Concentrations

    0.001 -1 µM

  • Incubation Time

    72 h
