The TIMER database confirmed that SERPINA1 mRNA expression was significantly higher in BLCA (bladder urothelial carcinoma), HNSC (head and neck squamous cell carcinoma), KIRC (kidney renal clear cell carcinoma), KIRP (kidney renal papillary cell carcinoma), STAD (stomach adenocarcinoma), THCA (thyroid carcinoma), and UCEC (uterine corpus endometrial carcinoma) than in paired normal tissues. This evidence concerns the gene SERPINA1 and uterine corpus endometrial carcinoma.
