Inflammation mediated by gut microbiome alterations promotes lung cancer development and an immunosuppressed tumor microenvironment

GSE271872 Mus musculus Expression profiling by high throughput sequencing 8 samples Submitted 2024/09/12 Platform GPL24247
Summary
This study aims to elucidate the impact of gut microbiota alterations on tumorigenesis and immune response in lung adenocarcinoma (LUAD). Using Gprc5a-/- mice as a model, we performed fecal microbiota transfer (FMT) from Gprc5a-/- and Gprc5a-/-; Lcn2-/- donors to investigate the role of gut microbiome changes in modulating tumor growth and the immune microenvironment. Single-cell RNA sequencing (scRNA-seq) was conducted on colonic lamina propria and subcutaneous tumor tissues. Our findings demonstrate that gut microbiota from Lcn2-deficient mice promotes systemic inflammation and immunosuppression, enhancing tumor progression. This study provides insights into the microbiome's influence on LUAD and potential therapeutic strategies targeting microbiome-related pathways.
