We recognize that low sample size is a limitation of our study, however validating the expression of a large number of transcripts simultaneously in the same samples by quantitative realtime PCR (low density array) and identification and confirmation of two proteins, mimecan (osteoglycin) and 14-3-3β in paired leiomyoma and myometrium compensated for this limitation. The gene discussed is OGN; the disease is leiomyoma.
