DHFR and lung adenocarcinoma: Interpretability analysis of 8 lung adenocarcinoma (LUAD) samples from the TCGA dataset revealed that in the 0-shot setting, three samples (TCGA-91-7771, TCGA-L9-A7SV, TCGA-64-5779) successfully identified DHFR, the known target of pemetrexed, along with its associated pathway folate biosynthesis (Table S13).
