Reprod Biomed Online 2023; 46:225-233. [PMID: 36396534 DOI: 10.1016/j.rbmo.2022.10.003] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2022] [Revised: 10/01/2022] [Accepted: 10/07/2022] [Indexed: 11/09/2022]
Abstract
RESEARCH QUESTION What is the molecular function of hsa_circ_0001550 in decidualization? DESIGN Human endometrial stromal cells (HESC) were isolated from the endometrium tissues to build an in-vitro decidualization model. Different concentrations of medroxyprogesterone acetate (MPA) were used to observe whether the expression level of hsa_circ_0001550 was related to progesterone. Biological characteristics and distribution of hsa_circ_0001550 were determined by RNase R, actinomycin D (Act D) assay and cytoplasmic/nuclear fraction assay. Then the overexpression of hsa_circ_0001550 was achieved by adenovirus vector. Cell proliferation was determined by Cell Counting Kit-8 (CCK-8) assays. The cell cycle was assessed by flow cytometry analyses. Cell apoptosis was determined by annexin-V/propidium iodide double staining experiment and western blotting. RESULTS The expression of hsa_circ_0001550 was decreased in decidua and decidualized HESC (P < 0.001, P = 0.014). Hsa_circ_0001550 is a covalently closed RNA molecule that was verified by RNase R assay and Act D assay (P = 0.012). Nuclear and cytoplasmic separation experiments confirmed that hsa_circ_0001550 was mainly distributed in the cytoplasm. Overexpression of hsa_circ_0001550 inhibited decidualization of HESC (P < 0.0001). Furthermore, overexpression of hsa_circ_0001550 inhibited proliferation by decreasing the number of S phase cells (P = 0.033). Annexin-V/propidium iodide double staining experiment and western blotting revealed that overexpression of hsa_circ_0001550 promoted HESC apoptosis (P < 0.001, P = 0.0139). CONCLUSIONS Hsa_circ_0001550 impairs decidualization of HESC. Progesterone decreases the expression of hsa_circ_0001550. The results may provide new insights into the cause of decidualization.

Abstract
Endometriosis is a condition that is influenced by hormones and involves stroma and glands being found outside the uterus; there are increases in proliferation, invasion, internal bleeding, and fibrosis. Matrix metalloproteinases (MMPs) have been suggested to be crucial in the progression of invasion. The MMP family includes calcium-dependent zinc-containing endopeptidases, some of which not only affect the process of cell invasion but also participate in other physiological and pathological processes, such as angiogenesis and fibrosis. MMPs act as downstream-targeted molecules and their expression can be regulated by numerous factors such as estrogen, oxidative stress, cytokines, and environmental contaminants. Given their unique roles in endometriosis, MMPs may become effective biomarkers of endometriosis in the future. In the present review, we summarize the current literature on MMPs regarding their classification, function, and potential value for endometriosis, which may contribute to our knowledge of MMPs and MMP-targeted interventions.

Exp Ther Med 2020; 20:2191-2199. [PMID: 32765695 PMCID: PMC7401479 DOI: 10.3892/etm.2020.8914] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2019] [Accepted: 04/17/2020] [Indexed: 11/05/2022] Open
Abstract
The optimal protocol for endometrial preparation in patients with infertility remains unclear. Due to this, the current study retrospectively analyzed 1,589 patients with infertility and regular menstrual cycles to assess reproductive outcomes per embryo transferred and per embryo transfer (ET) cycle following the transfer of frozen-thawed embryos (FET) in a modified natural cycle (mNC) or hormone therapy cycle (HT) with or without gonadotropin-releasing hormone agonist (GnRHa)-induced pituitary suppression. The molecular mechanisms involved were also studied using tissues from endometrial biopsies. Patients who underwent FET were assigned to 5 groups as follows: Group A underwent a mNC (n=276); group B (n=338) received estradiol (E2) and progesterone (P4); group C received 1 cycle of GnRHa, E2 and P4 (n=323); group D received 2 cycles of GnRHa, E2 and P4 (n=329); and group E received 3 cycles of GnRHa, E2 and P4 (n=323). Tissues from endometrial biopsies of 91 patients performed on the day of ET were tested for endometrial receptivity marker mRNA expression and microRNA (miR)-223-3p mRNA. Furthermore, endometrial stromal cells (ESCs) were used for an in-depth study of the molecular mechanisms involved. Among the 5 groups of patients, implantation rates, clinical pregnancy rates and live birth rates were not significantly different. However, endometrial receptivity was enhanced in group E when compared with groups A-D, which was associated with endometrial leukemia inhibitory factor (LIF), osteopontin, vascular endothelial growth factor, integrin β3 and homeobox gene 10 and 11 mRNA upregulation, and miR-223-3p miRNA downregulation. Transfection of ESCs with an miR-223-3p mimic significantly reduced levels of LIF mRNA and protein. In addition, pre-treating ESCs with GnRHa upregulated mRNA and protein expression of the decidualization markers prolactin and insulin-like growth factor binding protein-1 in a time-dependent manner. In conclusion, these results indicated that HT with GnRHa may be a potential endometrial preparation protocol for FET.

Estrogen receptor β upregulates CCL2 via NF-κB signaling in endometriotic stromal cells and recruits macrophages to promote the pathogenesis of endometriosis. Hum Reprod 2020; 34:646-658. [PMID: 30838396 DOI: 10.1093/humrep/dez019] [Citation(s) in RCA: 54] [Impact Index Per Article: 13.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2018] [Revised: 01/24/2019] [Accepted: 02/08/2019] [Indexed: 12/14/2022] Open
Abstract
STUDY QUESTION How is the activation of estrogen receptor β (ERβ) in endometriotic stromal cells (ESCs) involved in macrophage recruitment to promote the pathogenesis of endometriosis? SUMMARY ANSWER ERβ modulates the production of C-C motif chemokine ligand 2 (CCL2) via nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) signaling in ESCs and thus recruits macrophages to ectopic lesions to promote pathogenesis. WHAT IS KNOWN ALREADY Macrophages are mainly recruited to the peritoneal cavity to promote the pathogenesis of endometriosis. Recent studies have demonstrated that ERβ plays an important role in the progression of endometriosis through modulating apoptosis and inflammation. STUDY DESIGN, SIZE, DURATION An observational study consisting of 22 cases (women with endometriosis, diagnosed by laparoscopy and histological analysis) and 14 controls (without endometriosis) was carried out. PARTICIPANTS/MATERIALS, SETTING, METHODS Tissues and stromal cells that were isolated from 22 patients with ovarian endometrioma and deeply infiltrating endometriosis were compared with tissues and stromal cells from 14 patients with normal cycling endometrium using immunohistochemistry, quantitative PCR, Western blot, cell migration assay and cloning formation assay. P values < 0.05 were considered significant, and experiments were repeated in at least three different cell preparations. MAIN RESULTS AND THE ROLE OF CHANCE We observed that accumulated macrophages were recruited to the ectopic milieu and mainly adopted an alternatively activated macrophage (M2) phenotype. To reveal the underlying mechanism for this, we conducted a series of experiments and found that high expression of ERβ led to the production of CCL2 via NF-κB signaling and macrophages were recruited to the ectopic milieu. An in vitro co-culture assay also suggested that the recruited macrophages in turn could promote the proliferation and clonogenic ability of ESCs. Overall, the activation of ERβ in ESCs is involved in macrophage recruitment via NF-κB/CCL2 signaling and subsequently appears to promote the pathogenesis of endometriosis. LARGE SCALE DATA N/A. LIMITATIONS, REASONS FOR CAUTION Due to the limitations of obtaining surgical specimens, endometrioma tissues were collected mainly from women diagnosed with middle to late stage endometriosis. We identified the predominant presence of M2 macrophages in the samples used in our study, but the underlying mechanism of how recruited macrophages acquire the M2 phenotype is undefined. WIDER IMPLICATIONS OF THE FINDINGS This work provides novel insight into the mechanism by which ERβ may modulate macrophage infiltration and promote pathogenesis, which may provide a new therapeutic target for endometriosis. STUDY FUNDING/COMPETING INTEREST(S) This study was supported by the National Natural Science Foundation of China (81671430). The authors have no conflicts of interest.

Abstract
PURPOSE To review the clinical, multimodality imaging, and pathologic characteristics of abdominal wall endometriosis (AWE), the most common type of extra-pelvic endometriosis. METHODS 116 women with histopathologically confirmed extragenital endometriosis diagnosed between 2/2014 and 6/2017 were evaluated retrospectively. Of these, 26 (22.4%) were found to have AWE and 18/26 met inclusion criteria for imaging. Available imaging studies were re-reviewed by two expert radiologists. Data regarding clinical features, histopathologic findings, and management were collected through medical record review. RESULTS 21 pathology-proven AWE deposits were identified by imaging in 18 women [mean age at diagnosis of 38.5 years (range 31-48)]. Prior C-section was present in 15/18 (83.3%) and pelvic endometriosis in 3/18 (16.7%) patients. Patients presented with abdominal pain in 14/18 (77.8%) cases, which was cyclical in 8/14; palpable mass in 12/18 (66.7%); fluid discharge in 2/18 (11.1%); and local skin discoloration in 2/18 (11.1%). Of the 21 lesions, 15 were evaluated with US, 10 with CT, and 5 with MRI. Mean lesion dimensions were 2.5 × 2.2 × 2.6 cm, and deposits were predominantly located at midline or left hemiabdomen [22/30 (73.3%)], were either stellate [15/30 (50%)] or round [15/30 (50%)] in shape, had ill-defined margins [21/30 (70%)], were heterogenous in appearance [27/30 (90%)], and involved both deep and superficial abdominal wall layers [17/30 (56.7%)]. On US, lesions were mainly isoechoic/hyperechoic [7/15 (46.7%)], and scarcely vascular [8/15 (53.3%)] with a peripheral vascular pattern [8/13 (61.5%)]. On CT, AWEs were hypervascular and homogeneous [8/10 (80%)], superiorly located to scar tissue, and on MRI lesions appeared hyperintense [4/5 (80%)] to muscle with T2 cystic and T1 hemorrhagic foci [4/5 (80%)]. In 23/27 (85.1%) original reports, there was at least one known mass prior to imaging; AWE was correctly diagnosed in only 7/23 (30.4%) cases. In those with no prior knowledge of a mass, the lesion was detected in 3/4 (75%), but AWE was only diagnosed in a single case. Median time between onset of symptoms and histopathology was 24.41 moths (IQR 15.18-47.33). CONCLUSIONS AWE is a challenging clinical entity frequently diagnosed with a significant delay and easily misinterpreted despite multimodality imaging. Familiarity with its radiologic features holds the potential for positively impacting diagnosis.

Abstract
One of the rarest forms of endometriosis is abdominal wall endometriosis (AWE), which includes caesarean scar endometriosis. AWE remains a challenging condition because some issues related to this topic are still under debate. The increasing number of caesarean sections and laparotomies will expect to increase the rate of AWE. The current incidence in obstetrical and gynaecological procedures is still unknown. The disease is probably underestimated. The pathogenic mechanism involves local environment at the implant site including local inflammation and metalloproteinases activation due to local growth factors, estrogen stimulation through estrogen receptors and potential epigenetic changes. However, the underlying mechanisms are not fully explained, and we need more experimental models to understand them. The clinical presentation is heterogeneous; the patient may be seen by a gynaecologist, an endocrinologist, a general surgeon, an imaging specialist, or even an oncologist. No particular constellation of clinical risk factors has been identified, and the histological report is the major diagnostic tool for confirmation. Surgery is the first line of therapy. Further on we need protocols for multidisciplinary investigations and approaches.
