Endometrial single cells to contribute preexisting endometriosis.

Endometrial single cells to contribute preexisting endometriosis. By Dr. Youngran Park

Endometriosis is an estrogen-dependent inflammatory disease. This disease affects approximately 10% of reproductive-aged women and 20% to 50% of infertile women. Multiple hypotheses have been proposed for the origin of endometriosis. Retrograde menstruation is believed to take part by the…

Non-coding RNAs in endometriosis

Non-coding RNAs in endometriosis By Dr. Youngran Park

The pathophysiological mechanisms causing the development of endometriosis, which is a heterogeneous disease remain enigmatic, and a lack of effective biomarkers necessitates surgical intervention for diagnosis. Non-coding RNA (ncRNA) molecules, which are important regulators of cellular function, have been implicated…

Endometrial stem cells and Endometriosis

Endometrial stem cells and Endometriosis By Dr. Youngran Park

Human endometrium is a cyclically proliferative tissue, and this monthly regeneration is likely mediated by endometrial stem (or progenitor) cells.The upper functional layer of the endometrium breaks down and is shed into the uterine cavity during menstruation. Re-epithelialization and repair…

Enhanced UGT1A1 Gene and Protein Expression in Endometriotic Lesions.

Enhanced UGT1A1 Gene and Protein Expression in Endometriotic Lesions. By Dr. Youngran Park

The estrogen plays an essential role in endometriosis. Lately, it is becoming evident that, besides the circulating levels of estrogens, the balance of synthesis versus inactivation (metabolism) of estrogens by intralesional steroid-metabolizing enzymes also determines the local net estrogen availability.…

The endometrial stem cell markers notch-1 and numb are associated with endometriosis.  By Dr. Youngran Park

The pathological mechanisms of endometriosis are still poorly understood. However, stem cells have been candidates of interest because of their high proliferation potential and their ability to differentiate into multiple lineages, contributing to characteristic traits of endometriosis. Also, previous studies…

Progesterone resistance can cause endometriosis

Progesterone resistance can cause endometriosis By Demet Candaş Green

Progesterone is a steroid hormone produced by the corpus luteum of ovaries. Abnormal progesterone signaling (i.e., progesterone resistance) in the endometrium has been implicated in the establishment of eutopic and ectopic endometrial implants. Several causes for faulty progesterone signaling have been…
