title: Gene expression patterns of insulin-like growth factor 2 in human uterine fibroid tissues: a genetic study with clinical correlations.
abstract: OBJECTIVE
  We investigated insulin-like growth factor 2 (IGF-2) gene activity in human uterine fibroid tissue. Results of the genetic testing were correlated with clinical data.
  
  
  METHODS
  We obtained samples from patients treated for uterine fibroid and from patients undergoing hysterectomy due to other indications (control group). The examined group (with fibroid) contained 101 cases, while the control group was similar with 110 patients. Gene expression values were determined using the standard PCR technique. Clinical data were available from the computer database of the department.
  
  
  RESULTS
  IGF-2 gene expression was significantly higher in the fibroid group. There was no correlation between increase in gene activity and the number of tumors. History of previous uterine fibroid did not seem to predict IGF-2 gene activity in the current fibroid tumor tissue. IGF-2 gene expression did not correlate with cumulative duration of lactation following prior pregnancies.
  
  
  CONCLUSIONS
  IGF-2 gene activity is significantly increased in leiomyoma tissue compared to normal myometrium. Familial aggregation of uterine fibroids is not significantly associated with increased IGF-2 gene activity; other genes may have a stronger etiological role. It appears that the genetic factors potentially important in the development of familiar uterine leiomyoma are not related to the IGF-2 gene.
