title: Seladin-1/DHCR24 expression in normal ovary, ovarian epithelial and granulosa tumours.
abstract: OBJECTIVE
  The human DIMINUTO/DWARF1 homolog seladin-1/DHCR24 has been recently reported to be up-regulated in adrenocortical adenomas. Seladin-1 expression has been reported in the normal ovary. Granulosa cell tumours of the ovary (GCT) as with adrenocortical adenomas arise from a steroidogenic tissue, respond to pituitary hormone stimulation and synthesize steroid hormones.
  
  
  METHODS
  To test the hypothesis that seladin-1 may also have a role in the pathogenesis of GCT, we determined the expression of seladin-1 in a cohort of GCT and in mucinous and serous cystadenocarcinomas and in normal ovary.
  
  
  METHODS
  Expression was determined by RT-PCR using gene specific primers and probes combined with Southern blot analysis of the PCR products.
  
  
  RESULTS
  Seladin-1 expression was identified in the normal ovary, mucinous cystadenocarcinomas and serous cystadenocarcinomas of the ovary whereas no expression was observed in the GCT.
  
  
  CONCLUSIONS
  Based on our results, seladin-1 is not expressed in the granulosa cells or at least not in those that give rise to GCT.
