    ..These results give evidence for the structural basis of steroid recognition by 17beta-HSD1 and throw light on the design of new inhibitors for this pivotal steroid enzyme. ..
  2. Thériault J, Lin S. The dual sex hormone specificity for human reductive 17?-hydroxysteroid dehydrogenase type 7: synergistic function in estrogen and androgen control. J Steroid Biochem Mol Biol. 2018;: pubmed publisher
    ..These results strongly support that the inhibition of 17?-HSD7 constitutes the basis of breast cancer cell proliferation decreasing that led to the shrinkage of xenograft ER?+?breast tumor mice model. ..

    ..The multi-specificity contributes significantly to steroid metabolism in peripheral tissues, due to the high levels of 17beta-HSD5 mRNA in both breast and prostate tissues. ..

    ..The results show that the V54L mutation significantly decreases the 3?-HSD activity for the reduction of DHT, while this mutation enhances the 20?-HSD activity to convert progesterone. ..

    ..17β-HSD1 and -7 are principal reductive 17β-HSDs and major players in the viability of estrogen-dependent breast cancer cells. Combined targeting of these enzymes may be potential for molecular therapy of such cancer. ..
