Newest firstMaintaining a quiescent uterus until labor is of utmost importance for a successful pregnancy and still represents the most challenging issue in clinical practice. Despite the existence of standard approaches (short-term use of tocolytic agents or preventive use of vaginal progesterone), whose efficacy is still controversial, several natural molecules have garnered attention in recent years as an effective therape…
Open article record in new tab ↗In recent years, significant progress has been made in understanding the biological and molecular pathways that regulate the effects of ischemia-reperfusion (I/R) injuries. However, despite these developments, various pharmacological agents are still being tested to either protect against or mitigate the damage caused by the IR's harmful consequences. JWH133 is a CB2R-selective agonist and belongs to the class of…
Open article record in new tab ↗Background Early pregnancy events, including embryo implantation, are critical for maintaining a healthy pregnancy and facilitating childbirth. Despite numerous signaling pathways implicated in establishing early pregnancy, a comprehensive understanding of implantation remains elusive. Methods This paper provides a comprehensive review of the current research on lipids in the context of early pregnancy, with a par…
Open article record in new tab ↗The endocannabinoid (eCB) system has gained ground as a key modulator of several female fertility-related processes, under physiological/pathological conditions. Nevertheless, its modulation during reproductive aging remains unclear. This study aimed to investigate the expression levels of the main receptors (cannabinoid receptor 1,CB1; cannabinoid receptor 2, CB2; G-protein coupled receptor, GPR55; and transient…
The endocannabinoid system (ECS) is a cell-signaling system present in multiple organ systems and is an integral part of sustaining the microenvironment necessary for early pregnancy success and maintenance. It plays a significant role in embryo development, transport and implantation as well as placentation. The current theory behind the initiation of term labor is that it is a complex, multifactorial process inv…
Open article record in new tab ↗Background The denomyotic junctional zone (JZ) plays an important role in the pathogenesis of adenomyosis. Proliferating cell nuclear antigen (PCNA) is an important nuclear marker of cell proliferation. This study aimed to evaluate the effects of the cannabinoid receptor CB1 on proliferation and apoptosis in the JZ in women with and without adenomyosis. Methods JZ smooth muscle cells (JZSMCs) of the adenomyosis an…
Prostaglandins (PG) are effective abortifacients and are important mediators of lipopolisaccharide (LPS)-induced embryonic resorption (ER). Besides, anandamide (AEA) has been described as one of the major endocannabinoids present in the uterus suggesting that it might play a role in reproduction. It has been reported that high levels of AEA are associated with pregnancy failure and that LPS increases AEA productio…
Bioactive lipid molecules as lysophosphatidic acid (LPA), prostaglandins (PG) and endocannabinoids are important mediators of embryo implantation. Based on previous published data we became interested in studying the interaction between these three groups of lipid derivatives in the rat uterus during the window of implantation. Thus, we adopted a pharmacological approach in vitro using LPA, DGPP (a selective antag…
Nitric oxide production, catalyzed by nitric oxide synthase (NOS), should be strictly regulated to allow embryo implantation. Thus, our first aim was to study NOS activity during peri-implantation in the rat uterus. Day 6 inter-implantation sites showed lower NOS activity (0.19±0.01 pmoles L-citrulline mg prot(-1) h(-1)) compared to days 4 (0.34±0.03) and 5 (0.35±0.02) of pregnancy and to day 6 implantation sites…
