Next we investigated RPC-9/NaqR cells, which were derived from gefitinib-resistant lung adenocarcinoma cell lines (RPC-9 cells harboring the EGFR exon 19del and T790M mutations). Exposure to naquotinib inhibited the phos
[Paragraph-level] PMCID: PMC5792548 Section: RESULTS PassageIndex: 10
Evidence Type(s): Predictive, Oncogenic
Justification: Predictive: The passage discusses gefitinib-resistant lung adenocarcinoma cell lines harboring the EGFR exon 19del and T790M mutations, indicating a correlation with resistance to therapy, specifically gefitinib. Oncogenic: The mention of the EGFR exon 19del and T790M mutations in the context of gefitinib resistance suggests that these somatic variants contribute to tumor development or progression in lung adenocarcinoma.
