Identification of RAC1 in Promoting Brain Metastasis of Lung Adenocarcinoma using Single-cell Transcriptome Sequencing

ABSTRACT: Brain metastases are common in lung adenocarcinoma (LUAD) patients, and by far, the metastasis mechanisms are not fully understood. We performed a comprehensive single-cell level transcriptomic analysis on one LUAD patient with CTC, primary tumor tissue and metastatic tumor tissue using scRNA-seq approach to identify metastasis related biomarkers. Further scRNA-seq were performed on 7 patients to validate the cancer metastatic hallmark. with single cells collected from either metastatic or primary LUAD tissues. we obtained a more comprehensive picture over lung cancer metastasis in the single-cell level, giving a new perspective to the role of RAC1 in the LUAD brain metastasis, and related pathways to participate in the metastasis process.
