Efficacy of Low-Dose Estrogen–Progestins and Progestins in Japanese Women with Dysmenorrhea: A Systematic Review and Network Meta-analysis
Advances in therapy ·doi:10.1007/s12325-022-02298-9

INTRODUCTION: Although several studies suggest beneficial effects of low-dose estrogen-progestins (LEPs) and progestins on dysmenorrhea in Japanese women, the difference in efficacy between drugs remains unknown. METHODS: We identified stud…

Dienogest inhibits C-C motif chemokine ligand 20 expression in human endometriotic epithelial cells
European journal of obstetrics, gynecology, and reproductive biology ·doi:10.1016/j.ejogrb.2017.04.048

OBJECTIVE: C-C motif chemokine ligand 20 is thought to contribute to the development of endometriosis by recruiting Th17 lymphocytes into endometriotic foci. The present study investigated the effects of dienogest, a progesterone receptor a…

Dienogest, a synthetic progestin, down-regulates expression of CYP19A1 and inflammatory and neuroangiogenesis factors through progesterone receptor isoforms A and B in endometriotic cells
The Journal of steroid biochemistry and molecular biology ·doi:10.1016/j.jsbmb.2014.12.008

Dienogest (DNG) is a selective progesterone receptor (PR) agonist and oral administration of DNG is used for the treatment of endometriosis. DNG is considered to act on PR to down-regulate pathophysiological factors associated with endometr…

Dienogest improves human leucocyte antigen-DR underexpression and reduces tumour necrosis factor-α production in peritoneal fluid cells from women with endometriosis
European journal of obstetrics, gynecology, and reproductive biology ·doi:10.1016/j.ejogrb.2014.03.019

ObjectiveTo determine the immunological effect of dienogest (DNG), an oral anti-endometriosis drug, on peritoneal fluid (PF) macrophages collected from women with endometriosis. Although it has been suggested that DNG has direct effects on …

Progesterone and synthetic progestin, dienogest, induce apoptosis of human primary cultures of adenomyotic stromal cells
European journal of obstetrics, gynecology, and reproductive biology ·doi:10.1016/j.ejogrb.2014.05.031

OBJECTIVES: To investigate the direct effects of progesterone receptor (PR) agonists on proliferation and apoptosis of human adenomyotic cells. STUDY DESIGN: Human primary cultures of adenomyotic stromal cells (ASCs) from 24 patients with …

Dienogest inhibits nerve growth factor expression induced by tumor necrosis factor-α or interleukin-1β
Fertility and sterility ·doi:10.1016/j.fertnstert.2013.10.038

ObjectiveDienogest (DNG), a selective P receptor (PR) agonist, is used to treat endometriosis. To investigate whether DNG affects nerve growth factor (NGF) expression, we stimulated human endometrial epithelial cells (hEECs) with inflammato…

Dienogest inhibits aromatase and cyclooxygenase-2 expression and prostaglandin E2 production in human endometriotic stromal cells in spheroid culture
Fertility and sterility ·doi:10.1016/j.fertnstert.2011.11.005

ObjectiveTo determine the effect of dienogest (DNG) on the expression of aromatase and cyclooxygenase-2 (COX-2) and the production of prostaglandin E(2) (PGE(2)) in human endometriotic stromal cells (ESCs).DesignExperimental study in vitro.…

article 2011
Dienogest inhibits Toll-like receptor 4 expression induced by costimulation of lipopolysaccharide and high-mobility group box 1 in endometrial epithelial cells
·doi:10.1016/j.fertnstert.2011.09.040

ObjectiveTo investigate the effect of dienogest on the expression of Toll-like receptor (TLR) 4 in human endometrial epithelial cells.DesignProspective basic research study.SettingPharmaceutical research center.Patient(s)None.Intervention(s…

article 2010
Dienogest, a synthetic progestin, inhibits prostaglandin E2 production and aromatase expression by human endometrial epithelial cells in a spheroid culture system
Steroids ·doi:10.1016/j.steroids.2010.08.010

Prostaglandin E(2) (PGE(2)) is a major mediator in the pathophysiology, and pathogenesis of gynecological diseases associated with abnormal endometrial disease with proliferation and inflammation, such as endometriosis. In this study, we in…

Effect of dienogest administration on angiogenesis and hemodynamics in a rat endometrial autograft model
Human Reproduction ·doi:10.1093/humrep/deq241

BACKGROUND: We aimed to establish an endometrial autograft model in rats that would allow for repetitive in vivo analyses of angiogenesis. Dienogest (DNG) is an orally active progestin used for the treatment of endometriosis. We investigate…

Dienogest, a synthetic progestin, inhibits the proliferation of immortalized human endometrial epithelial cells with suppression of cyclin D1 gene expression
Molecular human reproduction ·doi:10.1093/molehr/gap042

Dienogest is a specific progesterone receptor agonist with potent oral endometrial activity and is used in the treatment of endometriosis. In this study, we examined the direct effects of dienogest on the proliferation of human endometrial …

Dienogest is a selective progesterone receptor agonist in transactivation analysis with potent oral endometrial activity due to its efficient pharmacokinetic profile
·doi:10.1016/j.steroids.2007.10.003

Dienogest was introduced as an oral progestin. Yet its strong oral potency on endometrial activity is not clearly explained. To circumvent this situation, steroid hormone receptor profiling using transactivation assay and endometrial activi…
