Endometriosis represents an estrogen-dependent disorder with a complex pathophysiology. Phytochemicals are promising candidates for endometriosis therapy, because they simultaneously target different cellular processes involved in the patho…

Angiogenesis, the development of new blood vessels from pre-existing ones, is an essential process determining numerous physiological and pathological conditions. Accordingly, there is a high demand for research approaches allowing the inve…

Endometriosis develop from shed endometrial fragments via retrograde menstruation. This affects the survival, proliferation and vascularization of the tissue and its final ability to form endometriotic lesions. Within this study, uterine ti…

STUDY QUESTION: Is there a difference in the growth and vascularization between murine endometriotic lesions originating from menstrual or non-menstrual endometrial fragments? SUMMARY ANSWER: Endometriotic lesions developing from menstrual …

Angiogenesis crucially contributes to various diseases, such as cancer and diabetic retinopathy. Hence, anti-angiogenic therapy is considered as a powerful strategy against these diseases. Previous studies reported that the acyclic monoterp…

BACKGROUND AND PURPOSE: Limited evidence suggests that the sphingosine-1-phosphate/sphingosine kinase 1 (S1P/SPHK1) signalling pathway is involved in the pathogenesis of endometriosis. Therefore, we analyzed in this study whether the inhibi…

BACKGROUND AND PURPOSE: The development of endometriotic lesions is crucially dependent on the formation of new blood vessels. In the present study, we analysed whether this process is regulated by erythropoietin-producing hepatoma receptor…

Ethnopharmacological relevanceCalligonum comosum is a desert plant that is applied in traditional folkloric medicine for the treatment of abnormally heavy or prolonged menstruation and menstrual cramps. Moreover, it has been suggested for t…

Accumulating evidence indicates that there is an interaction between the gut microbiota and endometriotic lesions. The new formation of these lesions is associated with stem cell recruitment, angiogenesis and inflammation, which may affect …

BACKGROUND: Vascularization is a major hallmark in the pathogenesis of endometriosis. An increasing number of studies suggests that multiple mechanisms contribute to the vascularization of endometriotic lesions, including angiogenesis, vasc…

The incorporation of endothelial progenitor cells (EPCs) into newly developing blood vessels contributes to the vascularization of endometriotic lesions. We analyzed whether cyclooxygenase (COX)-2 signaling regulates this vasculogenic proce…

BACKGROUND AND PURPOSE: Telmisartan suppresses the development of endometriotic lesions. However, the drug also up-regulates the expression of COX-2, which has been suggested to promote the progression of endometriosis. Accordingly, in the …

Angiogenesis is essential for the engraftment and growth of endometriotic lesions. In this study, we analyzed whether this process is regulated by Notch signaling. Endometriotic lesions were induced by endometrial tissue transplantation int…

Current endocrine therapeutics for the estrogen-dependent disease endometriosis often lead to considerable side-effects as they act by reducing estrogen action systemically. A more recent approach takes advantage of the fact that the weak e…

The incorporation of endothelial progenitor cells (EPCs) into microvessels contributes to the vascularization of endometriotic lesions. Herein, we analyzed whether this vasculogenic process is regulated by estrogen. Estrogen- and vehicle-tr…

BACKGROUND: The development and long-term survival of endometriotic lesions is crucially dependent on an adequate vascularization. Hyaluronic acid (HA) through its receptor CD44 has been described to be involved in the process of angiogenes…

Endometriosis is a frequent gynecologic disease with a complex, multifactorial cause. It is characterized by the cyclic estrogen-driven proliferation and bleeding of endometriotic lesions (ie, ectopic endometrial glands and stroma) outside …

STUDY QUESTION: Is telmisartan effective in the treatment of endometriosis? SUMMARY ANSWER: Combined blockade of angiotensin II type 1 receptor (AT1R) and activation of peroxisome proliferator-activated receptor (PPAR)-γ by telmisartan inhi…

In endometriosis research, endometriosis-like lesions are usually induced in rodents by transplantation of isolated endometrial tissue fragments to ectopic sites. In the present study, we investigated whether this approach is affected by th…

Endometriosis is a frequent gynecological disease, which is characterized by the presence of endometriotic lesions, i.e. ectopic endometrial glands and stroma, outside the uterine cavity. Most of these lesions are located in the peritoneal …

STUDY QUESTION: Does the phytochemical compound resveratrol inhibit vascularization of endometriotic lesions? SUMMARY ANSWER: Resveratrol suppresses the development of new microvessels in endometriotic lesions by inhibiting endothelial cell…

OBJECTIVE: To study the effect of combretastatin A4 phosphate (CA4P) on the vascularization of endometriotic lesions. DESIGN: Intravital microscopic, histologic, and immunohistochemical study. SETTING: University institute. ANIMAL(S): BA…

BACKGROUND Angiogenesis, i.e. the development of new blood vessels from pre-existing ones, represents an integral part in the pathogenesis of endometriosis. During the last decade, an increasing number of studies have therefore focused on t…

Endometriosis is a frequent gynecological disease, which is crucially dependent on the process of angiogenesis. However, the underlying regulatory mechanisms of blood vessel development are still poorly understood. CK2 is a pleiotropic prot…
