This analysis demonstrated that SLC47A1 was the only common gene interacting with ALDH3A2 in head and neck squamous cell carcinoma (HNSC), kidney renal clear cell carcinoma (KIRC), lung squamous cell carcinoma (LUSC), and uterine corpus endometrial carcinoma (UCEC) (Fig. 7A). This evidence concerns the gene SLC47A1 and head and neck squamous cell carcinoma.
