Up to 15% of women of reproductive property successful the United States endure from endometriosis, a information characterized by pelvic pain, menstrual cramps and infertility. Endometriosis develops erstwhile insubstantial similar the lining connected the wrong of the womb grows extracurricular of the uterus. This maturation whitethorn swell and bleed, starring to symptom and different symptoms.
Endometriosis affects millions of women astir the world.
Dr. Sang Jun Han“Endometriosis depends connected estrogen, a hormone good known for regulating a woman’s reproductive functions. Estrogen besides affects different organs specified arsenic the bosom and humor vessels, bones, breasts, skin, hair, mucous membranes, pelvic muscles and the brain,” said corresponding writer Dr. Sang Jun Han, subordinate prof of molecular and cellular biology and successful the Center for Reproductive Medicine astatine Baylor College of Medicine.
Endometriosis’ dependence connected estrogen and inflammation has guided treatments that are based connected systematically removing estrogen and utilizing anti-inflammatory drugs. “However, existent endometriosis treatments person debased efficacy, precocious recurrence complaint and origin adverse effects successful different tissues affected by estrogen,” said Han, who besides is simply a subordinate of Baylor’s Dan L Duncan Comprehensive Cancer Center. “Our extremity successful this survey published successful the Journal of Biomedical Science was to look for a amended attraction for this condition.”
Since endometriosis is an estrogen-dependent disease, estrogen receptors (ERs) ER-alpha and ER-beta, which mediate the hormones’ effects connected cells, play indispensable roles successful the improvement and progression of the condition. Previous enactment by the Han laboratory and others has shown that ER-beta contributes importantly to the progression of endometriosis.
Dr. Yuri Park“These findings suggest that selectively suppressing the enactment of ER-beta could assistance dainty the information without broadside effects of existent hormonal therapies targeting ER-alpha,” said archetypal writer Dr. Yuri Park, a postdoctoral subordinate successful the Department of Molecular and Cellular Biology astatine Baylor.
Working with cells successful the lab, Han and his colleagues screened a room of earthy products searching for compounds that could beryllium utilized to dainty endometriosis arsenic non-hormonal therapies.

Oleuropein is little costly than hormonal therapy, and our existent findings suggest that it is safer than existent treatments.
We are excited by these promising findings arsenic they enactment further exploration of the worth of oleuropein arsenic naturopathy for quality endometriosis treatment.”
