GAS6 and lung adenocarcinoma: To define the relevance of our experimental data in clinical practice, we investigated the prognostic value of the combined ENAH (hMENA), AXL, and GAS6 mRNA expression levels in pancreatic cancer (PDAC) patients (n = 172), lung squamous carcinoma (LUSC) (n = 501), and lung adenocarcinoma (LUAD) patient subtypes (n = 516) from The Cancer Genome Atlas (TCGA) (Network, 2012), (Liu et al, 2018).
