title: Association of estrogen receptor alpha and beta3-adrenergic receptor polymorphisms with endometrial cancer.
abstract: OBJECTIVE
  To investigate the association of estrogen receptor alpha and beta3-adrenergic receptor polymorphisms with endometrial cancer risk in Kagoshima, Japan.
  
  
  METHODS
  Ninety-two patients with endometrial cancer and 65 healthy women were enrolled in this study. Blood samples were collected, and deoxyribonucleic acid (DNA) was extracted. Estrogen receptor alpha and beta3-adrenergic receptor gene variants were analyzed by restriction fragment length polymorphisms using the restriction enzymes, Pvu II, Xba I for estrogen receptor alpha, and Mva I for beta3-adrenergic receptor. Multivariable logistic regression analysis was performed, and odds ratios (ORs) with 95% confidence intervals (CIs) were calculated.
  
  
  RESULTS
  The Pvu II PP genotype was associated with a decreased risk of endometrial cancer (multivariable OR 0.23; 95% CI 0.07, 0.82) compared with the pp genotype. The Xba I XX genotype was associated with a decreased risk for endometrial cancer (multivariable OR 0.26; 95% CI 0.09, 0.79) compared with the xx genotype. The Mva I variants were not associated with endometrial cancer risk (multivariable OR 0.55; 95% CI 0.20, 1.51).
  
  
  CONCLUSIONS
  Estrogen receptor alpha polymorphisms, but not beta3-adrenergic receptor gene, may be associated with a risk of endometrial cancer.
