Abstract
Adenomyosis is a debilitating gynecological disease of the uterus with no medicinal cure. The tissue injury and repair hypothesis for adenomyosis suggests that uterine hyperperistalsis or dysperistalsis plays a pivotal role in establishing adenomyotic lesions. However, specific impairments in uterine peristalsis and the underlying cellular signals for these changes in adenomyosis remain elusive. Here, we report a precision-cut uterine slice preparation that preserves in vivo uterine architecture and generates peristalsis similar to that seen in the whole uterus. We found that uterine peristalsis in neonatal mice at day 14 and adult mice at day 55 presents as bursts with multiple peaks induced by intracellular Ca2+ oscillations. Using a mouse model of adenomyosis induced by tamoxifen, a selective estrogen receptor modulator, we discovered that uterine peristalsis and Ca2+ oscillations from adenomyotic uteri on days 14 and 55 become spikes (single peaks) with smaller amplitudes. The peak frequency of Ca2+ oscillations or peristalsis does not show a difference between control and adenomyotic mice. However, both the estimated force generated by uterine peristalsis and the total Ca2+ raised by Ca2+ oscillations are smaller in uteri from adenomyotic mice. Uteri from adenomyotic mice on day 14, but not on day 55, exhibit hyperresponsiveness to oxytocin. Embryo implantations are decreased in adenomyotic adult mice. Our results reveal a mode switch from bursts to spikes (rather than an increased peak frequency) of uterine Ca2+ oscillations and peristalsis and concurrent hyperresponsiveness to oxytocin in the neonatal stage are two characteristics of adenomyosis. These characteristics may contribute to embryo implantation impairments and decreased fertility in adenomyosis.

[PMID: 30445932 PMCID: PMC6240221 DOI: 10.1186/s12885-018-5027-9] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2018] [Accepted: 10/31/2018] [Indexed: 11/10/2022] Open
Abstract
Background The large-conductance, voltage-gated, calcium (Ca (2+))-activated potassium channel (BKCa) plays an important role in regulating Ca (2+) signaling and cell physiological function, and is aberrantly expressed in some types of cancers. The present study focuses on identifying the oncogenic potential and clinical significance of BKCa in endometrial adenocarcinoma, as well as exploring the mechanistic relevance by 17β -estradiol (E2) inducing aberrant activation of MEK1/2 and ERK1/2 via BKCa. Methods The expression of BKCa, ERK1/2 and p-ERK1/2 were examined by immunohistochemical staining in 263 cases, including 185 primary types I endometrial cancer tissues, 38 atypical endometrial hyperplasia tissues and 40 normal endometrium tissues. Cell growth, cycle, apoptosis rate, migration and invasion was separately tested in Ishikawa cells using siRNA-BKCa and/or E2 treatment, as well as the expression of these interested proteins by western blot analysis. Results We showed that expression of BKCa is significantly elevated in 185 types I endometrial adenocarcinoma tissues compared to those of the normal endometrium and atypical endometrial hyperplasia tissues. Furthermore, in vitro observations revealed that down-regulation of BKCa expression inhibited cell growth by both enhancing apoptosis and blocking G1/S transition, suppressed cell migration and invasion in Ishakiwa cells, and decreased the expression of p-MEK1/2 and p-ERK1/2. Additionally, RNAi-mediated knockdown of BKCa attenuated the increased cellular growth and invasion, as well as the elevated expression of p-MEK1/2 and p-ERK1/2 proteins, induced by E2 stimulation. More importantly, the aberrant expression of BKCa and p-ERK1/2 were closely related with poor prognostic factors in type I endometrial cancer, and up-regulated expression of p-ERK1/2 was significantly associated with shorter disease-free survival (DFS) and overall survival (OS) and was an independent prognostic factor in type I endometrial cancer patients. Conclusion Our results demonstrated that BKCa and the key downstream effectors p-ERK1/2 could be involved in important signaling pathways in initiation and development of endometrial adenocarcinoma and may provide a new therapeutic approach for women with endometrial cancer.

Abstract
Adenomyosis is a common gynecologic disorder characterized by the presence of endometrial glands and stroma within the myometrium. The present study investigated the effect of quercetin in neonatal Imprinting Control Region mice with tamoxifen-induced adenomyosis. The body weight and hotplate response latency of all mice was examined at 4, 8, 12 and 16 weeks after birth. The mice dosed with tamoxifen were divided into four groups: high- or low-quercetin group, valproic acid (VPA) group and untreated group. The group of mice that were neonatally administrated with the solvent only (no tamoxifen), received no treatment and served as a blank control group. After 3 weeks of drug treatment, the potential ability of quercetin to improve the generalized hyperalgesia in mice with induced adenomyosis was evaluated by determining the body weight, pain modulation, examining the myometrial infiltration by histology examination of the uterus and detecting the expression of transient receptor potential cation channel subfamily V member 1 (Trpv-1), phospho (p)-p38 mitogen activated protein kinase p-extracellular signal-regulated kinase (p-ERK) in DRG neurons via immunohistochemistry. The results demonstrated that treatment with quercetin improved the generalized hyperalgesia by extending the hotplate response latency, reduced myometrial infiltration and decreased the expression levels Trpv-1, p-p38 and p-ERK in dorsal root ganglion neurons. The results indicated that quercetin decreases the incidence of hyperalgesia in mice with tamoxifen-induced adenomyosis, and the potential mechanism is through reduced central sensitization, which may be a promising treatment for adenomyosis.

Abstract
Background: Adenomyosis is a gynecological disorder with symptoms most presenting as dysmenorrhea and heavy menstrual bleeding. However, the presence of lower urinary tract symptoms (LUTS) among women with adenomyosis remains unclear. This study was designed to determine the prevalence of LUTS and factors related to the severity of these symptoms in this population. Methods: From July 2016 to November 2016, a total of 298 untreated symptomatic adenomyosis patients and 280 age-matched controls were enrolled. Demographics, LUTS, pain symptoms, ultrasonographic uterine size, and serum CA125 level were recorded. LUTS were evaluated using the International Prostate Symptom Score (IPSS) questionnaire. Factors related to the severity of LUTS were detected using the logistic regression analysis presented as odds ratio (OR) and 95% confidence interval (CI). Results: Compared with the control group, patients with adenomyosis had a greater IPSS total (4 [2–8] vs. 2 [0–3], Z = –8.159, P < 0.001), IPSS storage (2 [1–4] vs. 1[0–2], Z = –7.361 P < 0.001), and IPSS voiding (2 [0–4] vs. 0 [0–1], Z = –7.194, P < 0.001). Of the patients with adenomyosis, 30.2% had moderate-to-severe lower urinary tract symptoms (IPSS ≥8). The most prevalent LUTS were daytime frequency (40.9%), followed by nocturia (24.8%), weak stream (24.2%), and incomplete emptying (23.5%). In study group, patients with an IPSS total score ≥8 had higher proportion of menorrhagia (51.1% vs. 30.8%, χ2 = 11.162 P = 0.025) and larger uterine volumes (183.3 [109.8–273.8] cm3 vs. 148.5 [96.4–262.7] cm3, Z = –1.441, P = 0.150) compared to patients with an IPSS total score <8. On multivariate logistic regression analysis, patients with menorrhagia were associated with an increased risk of an IPSS total score ≥8 (OR: 2.309, 95% CI: 1.310–4.070, P = 0.004), an IPSS storage subscore ≥4 (OR: 2.422, 95% CI: 1.395–4.206, P = 0.002), and an IPSS voiding subscore ≥5 (OR: 1.971, 95% CI: 1.176–3.302, P = 0.010). However, patients with uterine volume more than 180 cm3 had more than 2-fold risk of bearing IPSS total score ≥8 (OR: 2.437, 95% CI: 1.381–4.300, P = 0.002), IPSS storage subscore ≥4 (OR: 2.486, 95% CI: 1.433–4.314, P = 0.001), and IPSS voiding subscore ≥5 (OR: 2.700, 95% CI: 1.485–4.908, P = 0.001). Conclusions: Lower urinary tract symptoms are prevalent in patients with symptomatic adenomyosis and greatly affect patients’ quality of life. Menorrhagia and large uterine volume could be potential risk factors that increase the occurrence of moderate-to-severe LUTS.

Abstract
Cannabis and cannabinoids are known to affect female reproduction. However, the role of the endocannabinoid system in mouse uterine contractility in the dioestrus and oestrus phases has not been previously investigated. The present study aimed at filling this gap. Endocannabinoid (anandamide and 2-arachidonoylglycerol) levels were measured in mouse uterus at dioestrus and oestrus phases by liquid chromatography-mass spectrometry; quantitative reverse transcription-PCR and western blot were used to measured the expression of cannabinoid receptors and enzymes involved in the metabolism of endocannabinoids. Contractility was evaluated in vitro either on the spontaneous contractions or by stimulating the isolated uterus with exogenous spasmogens. The tissue concentrations of anandamide and 2-AG were reduced in the oestrus phase, compared to dioestrus. Uteri obtained in the dioestrus, but not oestrus, phase showed spontaneous phasic prostaglandin-mediated contractions that were reduced by ACEA (CB1 receptor agonist) and to a lower extent by JWH133 (CB2 receptor agonist). These inhibitory effects were counteracted by the corresponding selective antagonists. Neither ACEA nor JWH133 did affect the contractions induced by exogenous PGE2 in the uterus from the oestrus phase. The FAAH inhibitor JNJ1661010 and, to a lower extent, the MAGL inhibitor JZL184 also reduced spontaneous contractions. It is concluded that the endocannabinoid system undergoes to adaptive changes between the oestrus and dioestrus phases. CB1 and, to a lower extent, CB2 receptor activation results in selective inhibition of myometrial contractility, without un-specific relaxing effects on the smooth muscle. These results might be of interest for female marijuana smokers as well as for the design of novel tocolytic agents.
