Transcriptomic profiling of Lung adenocarcinoma brain metastasis

ABSTRACT: Brain metastasis developed in nearly 40% of lung adenocarcinoma (LUAD) patients diagnosed with distant metastasis. There is lack of transcriptomic data of brain lesions from human lung adenocarcinoma patients. As part of the project to understanding the tumor microenvironment in brain metastasis of LUAD patients, we performed bulk RNA analysis on brain metastases from 6 LUAD patients. In order to understand the tumor intrinsic factors that potential shape the tumor microenvironment, we compared these data with bulk RNA sequencing data from 14 early stage and 11 late stage primary LUAD tumor from TCGA database. Pathway expression analysis showed a downregulation of pro-inflammatory signals in brain metastasis and upregulation of DNA synthesis and oxidative phosphorylation pathways related to rapid proliferation in brain lesions. Overall design: Performed bulk RNA sequencing on surgical resected metastatic brain tissue from 6 human lung adenocarcinoma patients using  Illumina HiSeq X ten platform.
