The Profile of Gut Microbiota in Carcinogenesis Driven by Mutant EGFR in Non-Small Cell Lung Cancer.

Purpose: Accumulating evidence has clarified that gut dysbiosis is involved in lung cancer development and progression. Although the relationship between tumors and gut microbiota has been extensively studied using clinical samples, no studies have examined the association between mutant EGFR-induced lung carcinogenesis and dysbiosis in gut microbiota. Therefore, we investigated the gut microbiota profiles in stool samples from human lung-specific conditional EGFR-mutant transgenic mice during lung tumor carcinogenesis.

Inhibition of AXL ameliorates pulmonary fibrosis attenuation of M2 macrophage polarization.

Rationale: Although a relationship between the Gas6/AXL pathway and pulmonary fibrosis (PF) has been suggested, the precise mechanisms and clinical implications of the AXL pathway in idiopathic pulmonary fibrosis (IPF) are still unclear.

Methods: Constitutive and conditional AXL-knockout mice were generated and injected with bleomycin (BLM) to induce pulmonary fibrosis. The expression of AXL and macrophage subtypes in BLM-injected mice and patients with IPF was analysed using flow cytometry.
