KRAS and non-small cell lung carcinoma: We next evaluated IFNγ responsiveness and MHC II induction across additional lung cancer lines, comparing murine KRAS mutant (CMT167, LLC) and EML4-ALK fusion (EA1, EA2) cell lines.14 15 NSCLC lines were subjected to IFNγ stimulation and analyzed for the expression of IFNγ-inducible cell surface proteins by flow cytometry (figure 2).
