Endometriosis involves high cyclooxygenase-2 (COX-2) and prostaglandin E2 (PGE2) production, driving disease progression and symptoms. Targeting COX-2 offers a promising therapeutic strategy for managing endometriosis.
Area of Science:
- Gynecological pathology
- Molecular biology
- Pharmacology
Background:
- Endometriosis (EMS) is a prevalent gynecological condition affecting women of reproductive age.
- EMS is characterized by chronic pelvic pain, painful intercourse, and infertility.
- Endometriotic lesions exhibit elevated cyclooxygenase-2 (COX-2) and prostaglandin E2 (PGE2) biosynthesis compared to normal endometrium.
Purpose of the Study:
- To review recent basic research on the role of COX-2 in endometriosis.
- To summarize current COX-2-targeted treatments for EMS.
Main Methods:
- Review of current scientific literature on COX-2 and endometriosis.
- Analysis of molecular mechanisms underlying COX-2 regulation and function in EMS.
- Summary of therapeutic strategies targeting COX-2.
Main Results:
- COX-2 expression is upregulated in EMS due to genetic, immune, and environmental factors, involving intracellular signals like MAPKs.
- COX-2 and its product PGE2 are crucial for EMS development, promoting cell proliferation, invasion, angiogenesis, and pain.
- PGE2 exerts its effects by binding to EP2 and EP4 receptors.
Conclusions:
- High COX-2 levels contribute significantly to the pathophysiology of endometriosis, including pain and infertility.
- Targeting COX-2, through inhibitors, hormone therapy, or glycyrrhizin, represents a viable therapeutic approach for EMS.

Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...
Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
Ovarian Cycle
Hormonal Control of the Ovarian Cycle
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...
