Identification of a disulfidptosis-related genes signature for prognostic implication in lung adenocarcinoma

•Construction of a gene signature associated with disulfidptosis in lung adenocarcinoma.•Higher risk score group has higher mortality and worse survival outcomes.•High-risk scoring group has worse immune microenvironment than low-risk scoring group.•The gene signature related to disulfidptosis had multiple effects on tumorigenesis, proliferation, and metastasis.
