Using the GTEx database as a supplement to the TIMER2 database, we further evaluated the expression of ASS1 in ACC (Adrenocortical carcinoma), DLBC (Diffuse large B-cell lymphoma), GBM, LGG (Brain lower grade glioma), SKCM, TGCT, THYM (Thymoma) and UCS (Uterine carcinosarcoma) between normal tissue and tumor tissue. This evidence concerns the gene ASS1 and thymoma.
