To determine whether the intracellular relationship between FKBP51 and HSD11β1 is specific to leiomyoma cells, cell culture experiments evaluating HSD11B1 mRNA expression in leiomyoma cells transfected with control vs FKBP5 siRNA and treated with DEX were repeated in cultured normal myometrial cells and HESCs obtained from uteri without leiomyoma. The gene discussed is FKBP4; the disease is leiomyoma.
