Urinary estrogen metabolites in women at high risk for breast cancer - 0 views

  • obesity has also been linked to preferential estrogen metabolism via the 16-alpha-hydroxylation pathway; thus, a prediction of the mechanism by which obesity could increase breast cancer risk would be through a lowering of the 2:16 ratio in favor of the 16 pathway
  • increased BMI was associated with a lower 2:16 OHE ratio
  • Our data show a significant association between alcohol use, defined as at least one drink per day or an average of seven per week, and 2:16 OHE ratio

  • An alcohol-induced rise in estrogens as a consequence of alcohol catabolism in the liver has been reported
  • The only study that looked at the association between alcohol and wine consumption in healthy women did not report a clear association
  • smoking has been reported to increase induction of the 2-hydroxylation metabolic pathway (24). However, the few epidemiological studies conducted on healthy women showed no difference in estrogen metabolites with smoking status (22) or smoking dose (20), in line with our findings.
  • Family history of a first-degree family member with breast cancer confers a 2- to 4-fold risk of developing breast cancer
  • 16% of breast cancers are due to unidentified hereditary factors
  • Estrogen metabolism occurs through enzymes whose activity is determined by the presence of specific genetic polymorphisms, thus can be defined as unique to each individual.
  • the metabolism is also influenced by a number of environmental factors, which change over a lifetime
  • significantly lower 2:16 OHE ratio in women who have known breast cancer risk factors compared with healthy women
  • There was an additional significant association specifically with BMI and alcohol use, which also supports the evidence that these factors affect estrogen metabolism
  • Profiling estrogen metabolites may identify women who are more likely to develop breast cancer within a population of women with known risk factors

    urinary estrogen metabolites shown to provide insight into breast cancer risk.  This study suggested that a low 2:16 OHE ratio increase breast cancer risk.

    Maybe the risks of estrogen metabolism is age dependent?  This Long Island Breast Cancer Study Project found that an increased 2:16alphOH-estrone ratio was associated with a reduced premenopausal, invasive breast cancer risk.  This association declined when looked at in postmenopausal women.

    study points to a modest decrease in dopamine and serotonin production in heroic users.  There appears to be a decrease in dopamine production, which could be via a down regulation of tyrosine hydroxylase enzyme and thus release.  Decreased homovanillate also noted.  Other studies have pointed to a decrease/downregulation of D2/D3 receptors.
