PI4K2A and non-small cell lung carcinoma: Given that PI4K2A’s prognostic impact in non–small cell lung cancer (NSCLC) is histologic subtype specific, we assessed the biological role of PI4K2A in cell lines isolated from diverse NSCLC subtypes, including LUSC (CALU-1), large cell carcinoma (H1299), and LUAD (A549, H441, HCC827).
