It is time for redefining endometriosis with our contemporary scientific knowledge -  Philippe Koninckx, MD, Ph.D. By Nasuhi Engin Aydin

Endometriosis defined as endometrium-like tissue outside the uterus has a poorly understood natural history. It is a heterogeneous disease having genetic-epigenetic features with many biochemical changes in the lesions. The Sampson hypothesis of implanted endometrial cells following retrograde menstruation is not…

A Possible genetic target for endometriosis treatment

A Possible genetic target for endometriosis treatment By Dr. Youngran Park

Mutations in the chromosome remodeling complex SWI/SNF subunit ARID1A were first identified in ovarian clear-cell carcinoma and ovarian endometrioid carcinoma, two endometriosis-associated epithelial ovarian cancer subtypes. ARID1A gene mutations are also observed in deep ovarian and deep infiltrating endometriosis, atypical endometrial…

Cancer-associated mutations and endometriosis

Cancer-associated mutations and endometriosis By Ellen Tumimbang

Endometriosis is thought to benign gynecological disease. However, recent studies compiled in this review paper suggest that spontaneous somatic mutations are driven to occur during the cyclic bleeding resulting in endometriosis tissue undergoing repeated tissue injury and repair. Mutations are…

Epigenetic link between endometriosis and cancer

Epigenetic link between endometriosis and cancer By Nasuhi Engin Aydin

Although endometriosis is considered a benign condition the cellular, histologic, and molecular data strongly demonstrate that endometriosis has neoplastic characteristics. There is strong evidence that endometriosis shares striking features with malignancy like normal tissue dissemination, invasion, and organ damage, as well as new vessel formation (neoangiogenesis).  In…

Endometriosis From an Epigenetic Lens

Endometriosis From an Epigenetic Lens By Kasthuri Nair

Samadieh et al. from the Royan Institute for Reproductive Biomedicine, recently published an article in Reproductive Sciences titled “Epigenetic Dynamics of HOXA10 Gene in Infertile Women With Endometriosis.” In this paper, the researchers wanted to observe HOXA10 gene expression in…

The use of histone deacetylase inhibitors for the treatment of endometriosis

The use of histone deacetylase inhibitors for the treatment of endometriosis By Murat Osman

Histone deacetylase inhibitors prevent the deacetylation of specific gene sequences thereby allowing the increased transcription of certain genes. Trichostatin A, a histone deacetylase inhibitor, has been seen to induce the expression of a pro-apoptotic gene called nonsteroidal anti-inflammatory drug-activated gene…

Inhibition of Histone methyltransferase for fighting endometriosis

Inhibition of Histone methyltransferase for fighting endometriosis By Dr. Youngran Park

Although the histone methyltransferase EZH2 and its product H3K27me3 are well studied in cancer, little is known about their role and potential as therapeutic targets in endometriosis. It has been previously reported that the endometriotic lesions are characterized by global…

Epigenetic regulation of the pathological process in endometriosis.

Epigenetic regulation of the pathological process in endometriosis. By Dr. Youngran Park

Epigenetic mechanisms have been recognized as important players in the development of a broad range of human diseases including endometriosis. A growing body of evidence shows that the remodeling of retrograde endometrial tissues to the ectopic endometriotic lesions involves multiple epigenetic…

Updates in the Field of Endometriosis: Epigenetics By Kasthuri Nair

In this chapter titled “A Review of the Epigenetic Contributions to Endometriosis,” Grimstad and Decherney examine various epigenetic influences that drive endometriosis disease progression. The epigenetic alterations they discuss include DNA methylation, histone modification, chromatin architecture changes, nuclear receptor modulation,…

DNA methylation changes in endometrium during the transition from pre-receptive to receptive phase

DNA methylation changes in endometrium during the transition from pre-receptive to receptive phase By Yu Yu

The endometrium is unique in that it undergoes remarkable changes during menstrual cycle under the control of hormones, estrogen, and progesterone. The function of the endometrium is crucial for embryo implantation, during which the endometrium is receptive around a week…
