Abstract
BACKGROUND: Cisplatin acquired resistance is a vital problem in the chemotherapy of non-small cell lung cancer, which needs to be further addressed. In recent years, obtaining drug resistant cells from cell cultivation and serving for metabolomics research to find differential metabolites and get potential biomarkers, is a good reference for clinical research and cancer treatment. This study aimed to obtain metabolite information related to cisplatin resistance through metabolomics analysis.Entities:
