摘要: The receptor tyrosine kinase AXL is a member of the Tyro3-Axl-Mer subfamily. affects several cellular functions, including growth and migration. aberration reportedly marker for poor prognosis treatment resistance in various cancers. In this study, we analyzed clinical, pathological, molecular features expression lung adenocarcinomas (LADs). We examined 161 LAD specimens from patients who underwent pulmonary resections. When protein was quantified (0, 1+, 2+, 3+) according to immunohistochemical staining intensity, results were 0: 35%; 1+: 20%; 2+: 37%; 3+: 7% samples. status did not correlate with clinical features, smoking pathological stage. However, whose showed strong (3+) had markedly poorer prognoses than other groups (P = 0.0033). Strong also significantly associated downregulation E-cadherin 0.025) CD44 0.0010). addition, 9 12 driver gene mutations (6 EGFR, 2 KRAS, 1 ALK). conclusion, found that surgically resected LADs predictor prognosis. characterized by mesenchymal status, higher stem-cell-like markers, frequent mutations.
