Research by Mengling et al. demonstrated that SLC38A2 is involved in glutamine crosstalk between TAMs and tumor cells in the Scissor_C1 cell subgroup of lung adenocarcinoma, accompanied by CAFs enrichment and epithelial-mesenchymal transition (EMT) phenotype (Li et al., 2023b). This evidence concerns the gene SLC38A2 and lung adenocarcinoma.
