ABO blood groups and expression of blood group antigens of epithelial ovarian cancer in Chinese women
BACKGROUND: ABO blood groups has been associated with risk of several cancers; however, the results for an association with ovarian cancer are inconsistent and little is known about the expression of histo‐blood group (ABH) antigens and ABO gene in ovarian tumor tissues. METHODS: To assess the impac...

Sumario: | BACKGROUND: ABO blood groups has been associated with risk of several cancers; however, the results for an association with ovarian cancer are inconsistent and little is known about the expression of histo‐blood group (ABH) antigens and ABO gene in ovarian tumor tissues. METHODS: To assess the impact of genotype‐derived ABO blood types on the risk of EOC, we conducted a case–control study in 1,870 EOC and 4,829 controls. Expression of A and B antigen in 70 pairs of ovarian tumor tissues and adjacent normal tissues were detected by immunohistochemistry. Gene expression and DNA methylation profiling was conducted in ovarian tumor tissues. RESULTS: We identified that blood group A was associated with increased risk for EOC compared to blood group O (OR = 1.18, 95% CI = 1.03–1.36, p = 0.019). Increased frequency of aberrant expression of histo‐blood group antigens was observed in patients with blood group A (76.5%) compared to patients with blood group O (21.1%) and B (5.0%) by immunohistochemistry (p < 0.001). ABO gene expression was down‐regulated in ovarian tumor tissues compared with paired adjacent normal tissues (p = 0.027). In addition, ABO gene expression was positively correlated with NFYB (r = 0.38, p < 0.001) and inversely correlated with DNA methylation level of four CpG sites on ABO gene (cg11879188, r = − 0.3, p = 0.002; cg22535403, r = − 0.30, p = 0.002; cg13506600, r = − 0.22, p = 0.025; cg07241568, r = − 0.21, p = 0.049) in ovarian tumor tissues. CONCLUSION: We identified blood group A was associated with increased EOC risk in Chinese women and provided the clues of the possible molecular mechanisms of blood group A related to ovarian cancer risk. |
