Role of the endocannabinoid system in the pathophysiology of endometriosis and therapeutic implications. J Cannabis Res 2022; 4:54. [PMID: 36207747 PMCID: PMC9540712 DOI: 10.1186/s42238-022-00163-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2022] [Accepted: 09/30/2022] [Indexed: 11/25/2022] Open
Abstract
Endometriosis patients experience debilitating chronic pain, and the first-line treatment is ineffective at managing symptoms. Although surgical removal of the lesions provides temporary relief, more than 50% of the patients experience disease recurrence. Despite being a leading cause of hysterectomy, endometriosis lacks satisfactory treatments and a cure. Another challenge is the poor understanding of disease pathophysiology which adds to the delays in diagnosis and overall compromised quality of life. Endometriosis patients are in dire need of an effective therapeutic strategy that is both economical and effective in managing symptoms, while fertility is unaffected. Endocannabinoids and phytocannabinoids possess anti-inflammatory, anti-nociceptive, and anti-proliferative properties that may prove beneficial for endometriosis management, given that inflammation, vascularization, and pain are hallmark features of endometriosis. Endocannabinoids are a complex network of molecules that play a central role in physiological processes including homeostasis and tissue repair, but endocannabinoids have also been associated in the pathophysiology of several chronic inflammatory diseases including endometriosis and cancers. The lack of satisfactory treatment options combined with the recent legalization of recreational cannabinoids in some parts of the world has led to a rise in self-management strategies including the use of cannabinoids for endometriosis-related pain and other symptoms. In this review, we provide a comprehensive overview of endocannabinoids with a focus on their potential roles in the pathophysiology of endometriosis. We further provide evidence-driven perspectives on the current state of knowledge on endometriosis-associated pain, inflammation, and therapeutic avenues exploiting the endocannabinoid system for its management.

Higher Risk of Anxiety and Depression in Women with Adenomyosis as Compared with Those with Uterine Leiomyoma. J Clin Med 2022; 11:jcm11092638. [PMID: 35566763 PMCID: PMC9099604 DOI: 10.3390/jcm11092638] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2022] [Revised: 04/28/2022] [Accepted: 05/05/2022] [Indexed: 02/06/2023] Open
Abstract
The main symptoms of adenomyosis may adversely affect physical and mental health and quality of life (QOL). However, studies are few on this topic. This study evaluated the effect of adenomyosis on anxiety, depression, and QOL. Participants with adenomyosis (n = 90) or leiomyoma (n = 59) completed questionnaires, including the visual analog scale (VAS) for pain, Hospital Anxiety and Depression Scale (HADS), and Short Form (SF)-36. HADS anxiety and depression positive rates, physical (PCS) and mental (MCS) component summary scores, and eight subscale scores of SF-36 were compared between the two groups. Among patients with adenomyosis, the incidence of anxiety symptoms was 28.9% (control group, 10.2%; OR = 3.589, 95%CI: 1.375–9.367), with 10% of patients showing moderate-to-severe symptoms. The incidence of depressive symptoms was 14.4% (control group, 3.4%; OR = 4.812, 95%CI: 1.044–22.168). The case group had significantly lower PCS and MCS scores than the control group. In patients with adenomyosis, being employed (OR = 6.393, 95%CI: 1.153–35.440) and perianal pain (OR = 25.419, 95%CI: 2.504–258.024) were risk factors for anxiety, and perianal pain (OR = 15.208, 95%CI: 3.050–75.836) was a risk factor for depression. Compared with leiomyoma, adenomyosis is associated with a higher risk of anxiety and depression, with a poorer QOL.

Abstract
OBJECTIF Fournir aux fournisseurs de soins de santé les meilleures données probantes sur l'utilisation de cannabis et la santé des femmes. Les domaines d'intérêt sont : les profils généraux d'utilisation du cannabis ainsi que la sécurité de la consommation; les soins aux femmes qui utilisent le cannabis; la stigmatisation; le dépistage, l'intervention brève et l'orientation vers le traitement; les effets sur la régulation hormonale; la santé reproductive, y compris la contraception et la fertilité; la fonction sexuelle; les effets sur les symptômes périménopausiques et postménopausiques; et l'utilisation dans le traitement des syndromes de douleur pelvienne chronique. POPULATION CIBLE La population cible comprend toutes les femmes qui consomment ou utilisent du cannabis ou qui envisagent de le faire. RéSULTATS: Un dialogue ouvert et fondé sur des données probantes relativement à l'utilisation et la consommation de cannabis, dialogue qui mènera à l'amélioration des soins aux patientes. BéNéFICES, RISQUES ET COûTS: L'exploration de l'utilisation et de la consommation de cannabis par une approche basée sur la connaissance des traumatismes donne l'occasion au fournisseur de soins et à la patiente de créer une solide alliance thérapeutique collaborative. Cette alliance permet aux femmes de faire des choix éclairés sur leurs propres soins. Elle facilite également le diagnostic et le traitement possible des troubles de l'usage du cannabis. Il ne faut pas stigmatiser la consommation, car la stigmatisation nuit à l'alliance thérapeutique (c'est-à-dire le partenariat entre la patiente et le fournisseur de soins). Plusieurs effets indésirables de la consommation de cannabis peuvent être confondus avec d'autres problèmes de santé. À l'heure actuelle, l'utilisation du cannabis pour traiter les problèmes de santé féminine n'est pas financée par le secteur public; par conséquent, les utilisatrices doivent assumer les coûts directs. Les coûts indirects de l'utilisation de cannabis sont inconnus. Ainsi, les fournisseurs de soins et les patientes doivent comprendre le rôle du cannabis dans les problèmes de santé féminine de sorte que les femmes puissent prendre des décisions éclairées. DONNéES PROBANTES: Des recherches ont été effectuées dans PubMed, Embase et la littérature grise pour recenser des études publiées entre le 1er janvier 2018 et le 18 février 2021 concernant l'utilisation du cannabis et ses effets sur l'infertilité, la contraception, les symptômes périménopausiques et postménopausiques et la douleur pelvienne. Toutes les publications des types suivants ont été incluses : essais cliniques, études observationnelles, revues (y compris les revues systématiques et les méta-analyses), directives cliniques et déclarations de conférences de consensus. Un survol des publications a été effectué pour en confirmer la pertinence. Les termes de recherche ont été définis à l'aide des termes MeSH (Medical Subject Headings) et mots clés (et variantes) suivants : cannabis, cannabinoids, marijuana, dexanabinol, dronabinol et tetrahydrocannabinol. À ces termes ont été combinés les termes suivants afin de cerner la santé des femmes : estrogen, estradiol, medroxyprogesterone acetate, vaginal contraception, oral contraceptives, fertilization, amenorrhea, oligomenorrhea, pelvic pain, dysmenorrhea, endometriosis, interstitial cystitis, vulvodynia et menopause. MéTHODES DE VALIDATION: Les auteurs ont évalué la qualité des données probantes et la force des recommandations en utilisant l'approche d'évaluation, de développement et d'évaluation (GRADE).

Abstract
OBJECTIVE To provide health care providers with the best evidence on cannabis use with respect to women's health. Areas of focus include general patterns of cannabis use as well as safety of use; care for women who use cannabis; stigma; screening, brief intervention, and referral to treatment; impact on hormonal regulation; reproductive health, including contraception and fertility; sexual function; effects on perimenopausal and menopausal symptoms; and use in chronic pelvic pain syndromes. TARGET POPULATION The target population includes all women currently using or contemplating using cannabis. OUTCOMES Open, evidence-informed dialogue about cannabis use, which will lead to improvement in patient care. BENEFITS, HARMS, AND COSTS Exploring cannabis use through a trauma-informed approach provides the health care provider and patient with an opportunity to build a strong, collaborative, therapeutic alliance. This alliance empowers women to make informed choices about their own care. It also allows for the diagnosis and possible treatment of cannabis use disorders. Use should not be stigmatized, as stigma leads to poor "partnered care" (i.e., the partnership between the patient and care provider). Multiple side effects of cannabis use may be mistaken for other disorders. Currently, use of cannabis to treat women's health issues is not covered by public funding; as a result, individual users must pay the direct cost. The indirect costs of cannabis use are unknown. Thus, health care providers and patients must understand the role of cannabis in women's health issues, so that women can make knowledgeable decisions. EVIDENCE PubMed, EMBASE, and grey literature were searched to identify studies of "cannabis use and effect on infertility, contraception, perimenopause and menopausal symptoms, and pelvic pain" published between January 1, 2018 and February 18, 2021. All clinical trials, observational studies, reviews (including systematic reviews and meta-analyses), guidelines, and conference consensus statements were included. Publications were screened for relevance. The search terms were developed using the Medical Subject Headings (MeSH) terms and keywords (and variants), including cannabis, cannabinoids, marijuana, dexanabinol, dronabinol, tetrahydrocannabinol; the specific terms to capture women's health were estrogen, estradiol, medroxyprogesterone acetate, vaginal contraception, oral contraceptives, fertilization, amenorrhea, oligomenorrhea, pelvic pain, dysmenorrhea, endometriosis, interstitial cystitis, vulvodynia, and menopause. VALIDATION METHODS The authors rated the quality of evidence and strength of recommendations using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. See online Appendix A (Tables A1 for definitions and A2 for interpretations of strong and weak recommendations). INTENDED AUDIENCE All heath care providers who care for women. SUMMARY STATEMENTS RECOMMENDATIONS.

Abstract
Abstract
Purpose of the Review
The purpose of this review is to provide a synopsis of all the mechanisms involved in the pathogenesis of adenomyosis. It will summarize recent advances in the field, discussing current controversies, and considering potential future directions.
Recent Findings
Adenomyosis pathogenesis is still a topic under investigation, however advancements in the understanding of disease development and mechanisms have been made. New data coming from new next generation sequencing-based studies and more-in-depth acquisitions on sex hormones imbalance, neuroangiogenesis, inflammation, fibrosis and cell proliferation have been obtained.
Summary
Adenomyosis is a uterine disorder that affects women of reproductive age, characterized by a benign invasion of the endometrium basalis (glands and stroma) within the myometrium.
So far, three theories for the pathophysiology of adenomyosis have been proposed:
An invagination of the endometrial basalis into the myometrium by tissue injury and repair.
The development from adult stem cells or displaced embryonic müllerian remnants.
An “invasion from outside to inside”.
In order to invade and develop, endometrial cells require a series of pathogenetic mechanisms which drive to adenomyosis. Altered sex steroids hormones receptors may be the primary event which causes increased endometrial cell proliferations and differentiation from epithelial to mesenchymal cells. Once invaded the myometrium, an inflammatory reaction is displayed, probably driven by local immune changes. The processes of neuroangiogenesis and fibrosis are also involved in the adenomyosis development and may explain some of the associated clinical symptoms (dysmenorrhea, abnormal uterine bleeding, and infertility).

N-Acyl Dopamines Induce Apoptosis in Endometrial Stromal Cells from Patients with Endometriosis. Int J Mol Sci 2021; 22:ijms221910648. [PMID: 34638988 PMCID: PMC8509064 DOI: 10.3390/ijms221910648] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2021] [Revised: 09/07/2021] [Accepted: 09/24/2021] [Indexed: 01/13/2023] Open
Abstract
Endometriosis is characterized by the formation and development of endometrial tissues outside the uterus, based on an imbalance between proliferation and cell death, leading to the uncontrolled growth of ectopic foci. The potential target for the regulation of these processes is the endocannabinoid system, which was found to be involved in the migration, proliferation, and survival of tumor cells. In this paper, we investigated the effect of endocannabinoid-like compounds from the N-acyl dopamine (NADA) family on the viability of stromal cells from ectopic and eutopic endometrium of patients with ovarian endometriosis. N-arachidonoyldopamine, N-docosahexaenoyldopamine, and N-oleoyldopamine have been shown to have a five-times-more-selective cytotoxic effect on endometrioid stromal cells. To study the mechanisms of the toxic effect, inhibitory analysis, measurements of caspase-3/9 activity, reactive oxygen species, and the mitochondrial membrane potential were performed. It was found that NADA induced apoptosis via an intrinsic pathway through the CB1 receptor and downstream serine palmitoyltransferase, NO synthase activation, increased ROS production, and mitochondrial dysfunction. The higher selectivity of NADA for endometriotic stromal cells and the current lack of effective drug treatment can be considered positive factors for further research of these compounds as possible therapeutic agents against endometriosis.

Abstract
Adenomyosis (ADS) is an estrogen-dependent gynecological disease with unspecified etiopathogenesis. Local hyperestrogenism may serve a key role in contributing to the origin of ADS. Talin1 is mostly identified to be overexpressed and involved in the progression of numerous human carcinomas through mediating cell proliferation, adhesion and motility. Whether Talin1 exerts an oncogenic role in the pathogenesis of ADS and puts an extra impact on the efficacy of estrogen, no relevant data are available yet. Here we demonstrated that the adenomyotic eutopic and ectopic endometrial stromal cells (ADS_Eu_ESC and ADS_Ec_ESC) treated with β-estradiol (β-E2) presented stronger proliferative and pro-angiogenetic capacities, accompanied by increased expression of PCNA, Ki67, VEGFB and ANGPTL4 proteins. Meanwhile, these promoting effects were partially abrogated by Fulvestrant (ICI 182780, an estrogen-receptor antagonist). Aberrantly upregulation of Talin1 mRNA and protein level was observed in ADS endometrial specimens and stromal cells. Through performing functional experiments in vitro, we further determined that merely overexpression of Talin1 (OV-Talin1) also enhanced ADS stromal cell proliferation and pro-angiogenesis, while the most pronounced facilitating effects were found in the co-intervention group of OV-Talin1 plus β-E2 treatment. Results from the xenograft nude mice model showed that the hypodermic endometrial lesions from co-intervention group had the highest mean weight and volume, compared with that of individual OV-Talin1 or β-E2 treatment. The expression levels of PCNA, Ki67, VEGFB and ANGPTL4 in the lesions were correspondingly elevated the most in the co-intervention group. Our findings unveiled that overexpressed Talin1 might cooperate withβ-E2 in stimulating ADS endometrial stromal cell proliferation and neovascularization, synergistically promoting the growth and survival of ectopic lesions. These results may be beneficial to provide a new insight for clarifying the pathogenesis of ADS.

Cannabis and Cannabinoids in Reproduction and Fertility: Where We Stand. Reprod Sci 2021; 29:2429-2439.

Abstract
Although cannabis use is increasing in general population, their prevalence among young adults is remarkably high. In recent years, their medical use gained a renewed interest. However, it can underline the reputation of cannabis being a harmless drug. Between cannabinoids, uniquely found on the cannabis plant, Δ9-tetrahydrocannabinol (THC) is the well-studied compound. It is responsible for the psychoactive effects via central cannabinoid receptors. Nevertheless, cannabinoids interact with other chemical signalling systems such as the hypothalamic-pituitary-gonadal axis. THC indirectly decreases gonadotropin-releasing hormone (GnRH) secretion by the hypothalamus. The consequences are diverse, and several key hormones are affected. THC disturbs important reproductive events like folliculogenesis, ovulation and sperm maturation and function. Although generally accepted that cannabinoid consumption impacts male and female fertility, prevailing evidence remains largely on pre-clinical studies. Here, we introduce cannabinoids and the endocannabinoid system, and we review the most prominent clinical evidence about cannabis consumption in reproductive potential and teratogenicity.

Abstract
Adenomyosis (ADS) is a commonly encountered benign gynecological disorder. Epithelial-mesenchymal transition (EMT) may serve a pivotal role in the pathogenesis of ADS. Talin1 has been identified to be implicated in multiple human carcinomas, probably through inducing EMT process. However, available data on the precise molecular mechanism of Talin1 in the pathogenesis of ADS remain extremely scanty. In the present study, we aim to investigate the clinical roles of Talin1 and its effects on uterine endometrial cell migration, invasion, and EMT in ADS. Relative mRNA expression of Talin1, microRNA-145-5p (miR-145-5p), and EMT-related markers was determined by qRT-PCR. Immunohistochemistry and immunofluorescence were performed to examine the distribution of Talin1 in ADS endometrium. Protein levels of Talin1, EMT-related markers, and wnt/β-catenin pathway were measured by western blot. Wound healing assay and transwell assay were utilized for evaluating cell migration and invasion respectively. Dual-luciferase reporter assay was performed to verify the relationship between Talin1 and miR-145-5p. We found Talin1 was markedly overexpressed in ADS endometrial tissue and cells, whereas miR-145-5p was downregulated. Elevated Talin1 mRNA level might be closely related to some clinicopathological features of ADS. Through functional experiments, we demonstrated that overexpression of Talin1 induced EMT and enhanced migration and invasion ability of ADS eutopic and ectopic endometrial epithelial cells (ADS_Eu_EEC and ADS_Ec_EEC) in vitro through activating the canonical wnt/β-catenin pathway. From a mechanistic perspective, Talin1 was inversely regulated by miR-145-5p as a direct target. Our findings unveiled that under the regulation of miR-145-5p, Talin1 might promote endometrial cell migration and invasion through inducing EMT, presenting a novel insight for elucidating the pathogenesis of ADS.

Abstract
Therapeutic agents used for non-small cell lung cancer (NSCLC) have limited curative efficacy and may trigger serious adverse effects. Cannabinoid ligands exert antiproliferative effect and induce apoptosis on numerous epithelial cancers. We confirmed that CB1 receptor (CB1R) is expressed in NSCLC cells in this study. Arachidonoylcyclopropylamide (ACPA) as a synthetic, CB1R-specific ligand decreased proliferation rate in NSCLC cells by WST-1 analysis and real-time proliferation assay (RTCA). The half-maximal inhibitory concentration (IC50) dose of ACPA was calculated as 1.39 × 10-12 M. CB1 antagonist AM281 inhibited the antiproliferative effect of ACPA. Flow cytometry and ultrastructural analyzes revealed significant early and late apoptosis with diminished cell viability. Nano-immunoassay and metabolomics data on activation status of CB1R-mediated pro-apoptotic pathways found that ACPA inhibited Akt/PI3K pathway, glycolysis, TCA cycle, amino acid biosynthesis, and urea cycle and activated JNK pathway. ACPA lost its chemical stability after 24 hours tested by liquid chromatography-mass spectrometry (LC-MS/MS) assay. A novel ACPA-PCL nanoparticle system was developed by nanoprecipitation method and characterized. Sustained release of ACPA-PCL nanoparticles also reduced proliferation of NSCLC cells. Our results demonstrated that low dose ACPA and ACPA-PCL nanoparticle system harbor opportunities to be developed as a novel therapy in NSCLC patients that require further in vivo studies beforehand to validate its anticancer effect.

Abstract
Simple Summary Cancers of the female reproductive system are common and are responsible for a large number of deaths in women. The exact reasons why some of these cancers occur are unknown. It is, however, known that for most of these cancers, several factors interact for them to happen. These interactions involve factors external and internal to the woman. An understanding of some of the internal factors involved in how these cancers arise will not only help drive preventive strategies, but will speed the development of new treatment approaches. The endocannabinoid system is a family including chemicals (known as endocannabinoids) produced in the body that are similar to those derived from the cannabis plant. This system, which is widely distributed in the body, has been shown to be involved in various functions. Its disruption has been shown to lead to various diseases, one of which is cancer. In this review, we summarise current knowledge of this system, its various constituents, and how they are involved in reproductive events and their pathologies, especially cancers. Furthermore, we discuss the role of the endocannabinoid system in these cancers and how targeting it could lead to new approaches to diagnosis and treatment of cancers of the female reproductive system. Abstract Gynaecological cancers can be primary neoplasms, originating either from the reproductive tract or the products of conception, or secondary neoplasms, representative of metastatic disease. For some of these cancers, the exact causes are unknown; however, it is recognised that the precise aetiopathogeneses for most are multifactorial and include exogenous (such as diet) and endogenous factors (such as genetic predisposition), which mutually interact in a complex manner. One factor that has been recognised to be involved in the pathogenesis and progression of gynaecological cancers is the endocannabinoid system (ECS). The ECS consists of endocannabinoids (bioactive lipids), their receptors, and metabolic enzymes responsible for their synthesis and degradation. In this review, the impact of plant-derived (Cannabis species) cannabinoids and endocannabinoids on gynaecological cancers will be discussed within the context of the complexity of the proteins that bind, transport, and metabolise these compounds in reproductive and other tissues. In particular, the potential of endocannabinoids, their receptors, and metabolic enzymes as biomarkers of specific cancers, such as those of the endometrium, will be addressed. Additionally, the therapeutic potential of targeting selected elements of the ECS as new action points for the development of innovative drugs will be presented.

Abstract
The endocannabinoid system (ECS) is one of the most crucial systems in the human organism, exhibiting multi-purpose regulatory character. It is engaged in a vast array of physiological processes, including nociception, mood regulation, cognitive functions, neurogenesis and neuroprotection, appetite, lipid metabolism, as well as cell growth and proliferation. Thus, ECS proteins, including cannabinoid receptors and their endogenous ligands’ synthesizing and degrading enzymes, are promising therapeutic targets. Their modulation has been employed in or extensively studied as a treatment of multiple diseases. However, due to a complex nature of ECS and its crosstalk with other biological systems, the development of novel drugs turned out to be a challenging task. In this review, we summarize potential therapeutic applications for ECS-targeting drugs, especially focusing on promising synthetic compounds and preclinical studies. We put emphasis on modulation of specific proteins of ECS in different pathophysiological areas. In addition, we stress possible difficulties and risks and highlight proposed solutions. By presenting this review, we point out information pivotal in the spotlight of ECS-targeting drug design, as well as provide an overview of the current state of knowledge on ECS-related pharmacodynamics and show possible directions for needed research.
