First, to explore the mechanism of resistance to naquotinib, we established naquotinib-resistant lung cancer cells using a cell line-based model. The following cell lines were examined: 1. EGFR-TKI-naive PC-9 cells harbo

Evidence Type(s): Predictive, Oncogenic
Justification: Predictive: The passage discusses the establishment of naquotinib-resistant lung cancer cells and mentions the effectiveness of naquotinib in inhibiting cell proliferation, indicating a correlation between the variants (19del and T790M) and resistance to therapy. Oncogenic: The presence of the T790M mutation in acquired gefitinib-resistant cells suggests that it contributes to tumor development or progression, as it is associated with resistance mechanisms in lung cancer.
