It was found that of 149 GM cases, 42.0%, 27.1% and 19.6% showed similar SULT1A1, 1C2 and 4A1 levels (>++) as that of tumor-surrounding tissues and the remaining parts showed reduction (+) and even absence (−) of SULT1A1, 1C2 and 4A1 expression. This evidence concerns the gene SULT1A1 and neoplasm.
