ABCC4 and non-small cell lung carcinoma: It is noteworthy that the combined protein expression score of ABCC4, DAG1, and SLC39A8 efficiently stratified patient outcome (p = 0.0013, HR: 8.378 [1.774, 39.57]; Figure 1A), suggesting that these three proteins could potentially be used as prognostic markers in NSCLC.
