The findings showed a positive association between the expression of KDR and ULBP1 and HS6ST2 expression in 11 different types of cancer (in particular, kidney renal papillary cell carcinoma, sarcoma, skin cutaneous melanoma, thyroid carcinoma, and uterine corpus endometrial carcinoma) (Fig. 10D,E). This evidence concerns the gene HS6ST2 and cancer.
