In a study conducted by Oliveira-Ferrer and colleagues, they compared mRNA expression levels of CHST3/7/11/12/13/15 between malignant and nonmalignant tumors.[6] They found that mRNA expression of CHST11, CHST12, and CHST15 was significantly higher in ovarian cancer samples compared with nonmalignant ones. The gene discussed is CHST11; the disease is ovarian cancer.
