title: Identification of new DNA markers of endometrial cancer in patients from the Ukrainian population.
abstract: OBJECTIVE
  To identify clinically significant molecular markers of endometrial cancer.
  
  
  METHODS
  Cancer and normal endometrial tissue samples from 20 patients of the Gynecology Clinic of Odessa State Medical University (Odessa, Ukraine) with confirmed endometrial cancer were compared for SSR and ISSR polymorphisms. Identified polymorphic fragments from anonymous genome regions situated between microsatellite repeats underwent direct DNA sequencing; analysis of their homology to sequences from human genome database has been performed.
  
  
  RESULTS
  No significant variability for the microsatellite loci adjacent to the E2F1, BAX, TCF7L2, C-MYC, WNT1, FES, DCC, P27, THRA, APC, CYP19 and P53 genes was detected. Search for new molecular markers of endometrial cancer within anonymous DNA sequences located between microsatellite repeats revealed 100 bp and 174 bp polymorphic fragments. These fragments were detected correspondingly in 60% and 35% of patients. 100 bp fragment appeared to be homologous to a region within the NFKB gene, 174 bp fragment - to a sequence within the DDR1 gene.
  
  
  CONCLUSIONS
  NFKB1 and DDR1 genes may be regarded as potential markers for some types of endometrial cancer. This is a first report about possible association of these genes with endometrial cancer.
