Knockdown of miR-150-5p reduces hypoxia-induced autophagy and epithelial-mesenchymal transition of endometriotic cells via regulating the PDCD4/NF-κB signaling pathway. Cytokine 2023; 162:156086. [PMID: 36427469 DOI: 10.1016/j.cyto.2022.156086] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2021] [Revised: 10/18/2022] [Accepted: 11/10/2022] [Indexed: 11/23/2022]
Abstract
BACKGROUND Hypoxia is an important microenvironmental factor that induces Endometriosis (EMs), but its mechanism remains unclear. Our study aims to investigate the mechanisms of miR-150-5p on hypoxia-induced EMs. METHODS Ovarian endometriosis cyst wall stromal cell lines CRL-7566 cells were treated with hypoxia. Cell migration ability was measured by Transwell assay. qRT-PCR was performed to detect miR-150-5p and PDCD4 expression. The autophagy-related proteins (LC3-I, LC3-II, Beclin-1, and p62), epithelial-mesenchymal transition (EMT) related proteins (E-cadherin, N-cadherin, and Vimentin) and NF-κB signaling pathway related proteins p65 expression were measured by western blot. Dual-luciferase reporter gene assay verified the binding relationship between miR-150-5p and PDCD4. RESULTS After hypoxia treatment, the miR-150-5p expression was up-regulated in CRL-7566 cells, while the expression of PDCD4 was down-regulated. In CRL-7566 cells, autophagy, migration and EMT were increased after hypoxia treatment. The autophagy inhibitor 3-MA inhibited hypoxia-induced the autophagy, migration and EMT of CRL-7566 cells. Hypoxia-induced autophagy and EMT of CRL-7566 cells were inhibited after knocking down miR-150-5p. Then miR-150-5p negatively regulated PDCD4 expression. PDCD4 knockdown reversed the inhibitory effect of miR-150-5p silencing on hypoxia-induced autophagy and EMT of CRL-7566 cells. Inhibiting the NF-κB signaling pathway weakened the effect of PDCD4 knockdown on hypoxia-induced autophagy and EMT of CRL-7566 cells. CONCLUSION MiR-150-5p silencing inhibited hypoxia-induced autophagy and EMT of endometriotic cells by regulating the PDCD4/NF-κB signaling pathway.

Abstract
Adenomyosis is a chronic benign uterine disease characterized by the presence of endometrial glands and stroma within the myometrium. It is a heterogeneous disease, presenting various clinical forms, depending on the location of the ectopic lesions within the myometrium. Adenomyosis can be responsible for several symptoms such as dysmenorrhea, abnormal uterine bleeding and/or infertility. Its pathophysiology is a real conundrum and several theories have been proposed: development of adenomyosis lesion could initiate de novo from Mullerian rests or from stem cells. Moreover, multiple factors could be involved in initiating lesions, including specific hormonal, immune and/or genetic changes. The objective of this review is to provide an update on adenomyosis pathophysiology, in particular on the various theories proposed concerning the invasion of the myometrium by endometrial cells and the inducing mechanisms, and to study the link between the physiopathology, the symptoms and the medical treatments.

Immune cells and Notch1 signaling appear to drive the epithelial to mesenchymal transition in the development of adenomyosis in mice. Mol Hum Reprod 2021; 27:6360467.

Abstract
The epithelial to mesenchymal transition (EMT) has been implicated in the development of adenomyosis, along with dysregulated immune responses. Inflammation potentially induces Notch signaling, which could promote this EMT. The objective of this study was to investigate the involvement of immune cells and Notch1-mediated EMT in the development of adenomyosis. Adenomyosis was induced in 18 CD-1 mice by neonatal oral administration of tamoxifen (TAM group), while 18 neonates received vehicle only (Control group). Their uteri were sampled at 30, 60 or 90 days of age. Immune cell markers (Cd45, Ly6c1, Cd86, Arginine1, Cd19, Cd4, Cd8), Notch1 and its target genes (Hey1, Hey2, Hes1, Hes5) and biomarkers of EMT (E-Cadherin, Vimentin, Tgfb, Snail1, Slug, Snail3) were analyzed by quantitative RT-PCR and immunohistochemistry. Activated-Notch1 protein was measured by western blot. Aberrant expression of immune cell markers was observed in the uteri of mice as they developed adenomyosis. The expression of inflammatory cell markers, notably M1 macrophages and natural killer cells, was increased from Day 30 in the TAM group compared to controls, followed by an increase in the Cd4 marker (T cells) at Day 60. Conversely, expression of the Cd19 marker (B cells) was significantly reduced at all of the stages studied. Notch1 signaling was also highly activated compared to controls at Day 30 and Day 60. Concomitantly, the levels of several markers for EMT were also higher. Therefore, the activation of Notch1 coincides with aberrant expression of immune and EMT markers in the early development of adenomyosis.

Adenomyosis is associated with specific proton nuclear magnetic resonance ( 1H-NMR) serum metabolic profiles. Fertil Steril 2021; 116:243-254. [PMID: 33849709 DOI: 10.1016/j.fertnstert.2021.02.031] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2020] [Revised: 02/15/2021] [Accepted: 02/16/2021] [Indexed: 12/17/2022]
Abstract
OBJECTIVE To determine whether the adenomyosis phenotype affects the proton nuclear magnetic resonance (1H-NMR)-based serum metabolic profile of patients. DESIGN Cohort study. SETTING University hospital-based research center. PATIENTS Seventy-seven patients who underwent laparoscopy for a benign gynecologic condition. INTERVENTIONS Pelvic magnetic resonance imaging and collection of a venous peripheral blood sample were performed during the preoperative workup. The women were allocated to the adenomyosis group (n = 32), or the control group (n = 45). The adenomyosis group was further subdivided into two groups: diffuse adenomyosis of the inner myometrium (n = 14) and focal adenomyosis of the outer myometrium (n = 18). Other adenomyosis phenotypes were excluded. MAIN OUTCOME MEASURES Metabolomic profiling based on 1H-NMR spectroscopy in combination with statistical approaches. RESULTS The serum metabolic profiles of the patients with adenomyosis indicated lower concentrations of 3-hydroxybutyrate, glutamate, and serine compared with controls. Conversely, the concentrations of proline, choline, citrate, 2-hydroxybutyrate, and creatinine were higher in the adenomyosis group. The focal adenomyosis of the outer myometrium and the diffuse adenomyosis phenotypes also each exhibited a specific metabolic profile. CONCLUSION Serum metabolic changes were detected in women with features of adenomyosis compared with their disease-free counterparts, and a number of specific metabolic pathways appear to be engaged according to the adenomyosis phenotype. The metabolites with altered levels are particularly involved in immune activation as well as cell proliferation and cell migration. Nevertheless, this study did find evidence of a correlation between metabolite levels and symptoms thought to be related to adenomyosis. Further studies are required to determine the clinical significance of these differences in metabolic profiles.

Abstract
BACKGROUND Endometriosis is a common gynaecological disease characterized by growth of uterine endometrial tissue, outside the uterine cavity, on the ovaries, oviduct and pelvic peritoneum. Isoliquiritigenin (ISL) is a natural flavonoid isolated from the root of licorice (Glycyrrhiza uralensis) and shallot (Allium cepa). ISL has previously shown antioxidant, anti-inflammatory, anti-proliferation and anti-tumor activities. PURPOSE This study aimed to investigate the effects of ISL on endometriosis in vivo and in vitro. METHODS End1/E6E7 endometriosis cells were treated with ISL and β-estradiol. The MTT assay was used to detect cell viability. Cell migration was evaluated by the wound-healing assay. The expression of epithelial-to-mesenchymal transition (EMT)-related proteins were detected by western blot. Female Balb/c mice, surgically induced to have endometriosis by transplanting uterine tissue into the abdominal cavity, were treated with ISL or vehicle for 4 weeks. Lesion growth was subsequently analyzed by high-resolution ultrasound imaging. Serum and lesion inflammatory cytokines were measured by ELISA. EMT-related proteins and apoptosis-related proteins of endometriotic lesions were detected by western blot. RESULTS It was observed that ISL treatment inhibited the viability and migration of End1/E6E7. ISL treatment increased the expression of E-cadherin, and decreased the expression of N-cadherin, Slug and Snail. In the animal model, ISL treatment reduced the volume and weight of endometriotic lesions, decreased serum and lesion inflammatory cytokines, inhibited EMT, and induced apoptosis of the lesions. CONCLUSION ISL inhibited the viability, migration and EMT-related proteins of End1/E6E7 cells, reduced the volume and weight of endometriotic lesions, inhibited inflammatory cytokines and EMT, and induced apoptosis of the lesions to improve endometriosis.

Abstract
Adenomyosis is also called internal endometriosis and affects about 20% of reproductive‐aged women. It seriously reduces life quality of patients because current drug therapies face with numerous challenges. Long‐term clinical application of mifepristone exhibits wonderful therapeutic effects with mild side‐effects in many disorders since 1982. Since adenomyosis is a refractory disease, we investigate whether mifepristone can be applied in the treatment of adenomyosis. In this study, we investigated the direct effects of mifepristone on human primary eutopic endometrial epithelial cells and stromal cells in adenomyosis. We found that mifepristone causes cell cycle arrest through inhibiting CDK1 and CDK2 expressions and induces cell apoptosis via the mitochondria‐dependent signalling pathway in endometrial epithelial cells and stromal cells of adenomyosis. Furthermore, mifepristone inhibits the migration of endometrial epithelial cells and stromal cells through decreasing CXCR4 expression and restricts the invasion of endometrial epithelial cells via suppression of epithelial‐mesenchymal transition in adenomyosis. We also found that mifepristone treatment decreases the uterine volume, CA125 concentration and increases the haemoglobin concentration in serum for adenomyosis patients. Therefore, we demonstrate that mifepristone could serve as a novel therapeutic drug in the treatment of adenomyosis, and therefore, the old dog can do a new trick.

Abstract
OBJECTIVE To study the impact of integrin-linked kinase (ILK) in endometrial stromal cells (ESCs) during decidualization. DESIGN Laboratory study with the use of human endometrium. SETTING University hospital. PATIENT(S) Fertile reproductive-age women who had not received hormonal treatment for 3 months before tissue collection. INTERVENTION(S) Endometrium tissue collection, in vitro decidualization of isolated ESCs, and small interfering (si) RNA transfection. MAIN OUTCOME MEASURE(S) Immunohistochemistry, ELISA, Western blot analysis, methylthiazolyl tetrazolium assay, and immunofluorescence staining. RESULT(S) In vivo expression of ILK is significantly increased in distended-fusiform stromal cells of late secretory endometrium and in cobblestone-shaped decidual cells of early pregnancy. During in vitro decidualization for up to 8 days, confluent cultures of isolated ESCs consistently displayed increased ILK expression and morphologic transformation from fibroblast-like to polygonal cells. Subsequent ILK knockdown by siRNA transfection reversed this transformation, accompanied by decreased phosphorylation of glycogen synthase kinase (GSK) 3β and decreased viable cell numbers. Immunofluorescence staining of the decidualized ESCs demonstrated linkage of increased levels of ILK at the tips of the fan-shaped organization of actin stress fibers located in the submembranous area, which expanded the decidual cells into a typical polygonal appearance. Knock-down of ILK abrogated the polymerization and organization of actin fibers, which reverted the cells to their undecidualized morphology. CONCLUSION(S) During human endometrial decidualization, ILK is essential for morphologic transformation of ESCs through organization of the actin cytoskeleton; it may also function through subsequent GSK3β signaling, which requires further studies.

Decreased Endometrial Expression of Leukemia Inhibitory Factor Receptor Disrupts the STAT3 Signaling in Adenomyosis During the Implantation Window. Reprod Sci 2016; 24:1176-1186.

Abstract
BACKGROUND Adenomyosis was found to have negative impacts on embryo implantation. Leukemia inhibitory factor (LIF), proposed to be a molecular marker for endometrial receptivity, works through the LIF receptor (LIFR) on both the embryo and the endometrium. We aimed to evaluate the endometrial expression of LIF and LIFR and its subsequent signaling in patients with adenomyosis during the window of implantation (WOI). METHODS Endometrium was obtained during the WOI from patients with adenomyosis (age <45 years) who underwent hysterectomy and from age-matched controls who had no endometriosis or adenomyosis. The LIF and LIFR expressions were measured by polymerase chain reaction for messenger RNA expression, immunohistochemistry for protein intensity and localization, and immunofluorescent staining for colocalization. The ratio of signal transducer and activator of transcription 3 (STAT3) to extracellular signal-regulated kinase (ERK) phosphorylation was measured by Western blot of both the endometrium and the isolated human endometrial stromal cells (ESCs). RESULTS Patients with adenomyosis showed significantly and parallelly reduced LIF and LIFR expressions in the eutopic endometrium during WOI as compared with the control women and subsequently with remarkably reduced activation of STAT3 and ERK signaling. The significantly increased STAT3 and ERK phosphorylation induced by the LIF treatment in the cultured ESCs supported the linkage between the LIF-LIFR reaction and the signaling cascade. CONCLUSION Significant reduction in LIFR expression and the reduced activation of subsequent signaling strongly suggest a working model of how the implantation markers, LIF, may affect the endometrium of patients with adenomyosis. These molecular changes supported the declined implantation rates reported in patients with adenomyosis.
