SULT2A1 and endometrial cancer: As SULT2A1 is not expressed in either endometrial cancer or adjacent control endometrium (Rubin et al., 1999), SULT2B1 is the major DHEA-specific SULT enzyme in endometrial cancer, and increased SULT2B1 expression has recently been reported in endometrial cancer, compared to adjacent control endometrium (Hevir et al., 2011).
