Metabolic reprogramming is a key feature of tumor cells and plays a key role in the adaptation of tumor cells to increased demands of biosynthesis and rapid proliferation.1 Numerous studies have shown that some key metabolic enzymes are essential for the initiation and progression of breast cancer(BC).These metabolic enzymes are involved in the regulation of many biological processes such as gene transcription,post-translational modification,and antioxidant capacity of cells,which endow tumor cells with the ability to adapt to divergent environmental stimuli.2 Therefore,it is of great significance to identify the role of important metabolic enzymes in the occurrence and development of BC to determine promising therapeutic targets.

Lung cancer(LC)is a prevalent and fatal malignancy,with high incidence and mortality rates.1 ATP binding cassette(ABC)transporters,a superfamily of integral membrane proteins,use ATP hydrolysis to facilitate substrate transport across cellular membranes.2 The pivotal role of ABC transporters in tumorigenesis was initially established by Mochida,3 who demonstrated that the loss of ABCB1 suppresses intestinal polyp formation and tumor progression in *** investigations have reported correlations between ABC transporters and the tumor microenvironment and cancer immunotherapy response,suggesting their modulatory effects on tumor progression and immunotherapy.
