Chiu CSC, Yeh LY, Pan SH, Li SH. Transcriptomic Analysis Reveals Intrinsic Abnormalities in Endometrial Polyps. Int J Mol Sci 2024; 25:2557. [PMID: 38473810 DOI: 10.3390/ijms25052557] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2024] [Revised: 02/08/2024] [Accepted: 02/19/2024] [Indexed: 03/14/2024] Open
Abstract
Endometrial polyps (EPs) are benign overgrowths of the endometrial tissue lining the uterus, often causing abnormal bleeding or infertility. This study analyzed gene expression differences between EPs and adjacent endometrial tissue to elucidate intrinsic abnormalities promoting pathological overgrowth. RNA sequencing of 12 pairs of EPs and the surrounding endometrial tissue from infertile women revealed 322 differentially expressed genes. Protein-protein interaction network analysis revealed significant alterations in specific signaling pathways, notably Wnt signaling and vascular smooth muscle regulation, suggesting these pathways play critical roles in the pathophysiology of EPs. Wnt-related genes DKK1 and DKKL1 were upregulated, while GPC3, GREM1, RSPO3, SFRP5, and WNT10B were downregulated. Relevant genes for vascular smooth muscle contraction were nearly all downregulated in EPs, including ACTA2, ACTG2, KCNMB1, KCNMB2, MYL9, PPP1R12B, and TAGLN. Overall, the results indicate fundamental gene expression changes promote EP formation through unrestrained growth signaling and vascular defects. The intrinsic signaling abnormalities likely contribute to clinical symptoms of abnormal uterine bleeding and infertility common in EP patients. This analysis provides molecular insights into abnormal endometrial overgrowth to guide improved diagnostic and therapeutic approaches for this troublesome women's health condition. Confirmation of expanded cohorts and further investigations into implicated regulatory relationships are warranted.

[PMID: 37603513 PMCID: PMC10443758 DOI: 10.1097/md.0000000000034864] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/02/2023] [Accepted: 07/31/2023] [Indexed: 08/23/2023] Open
Abstract
Endometrial hyperplastic processes (EHPs) encompass various morphological changes, characterized by an increased ratio of endometrial glands to stroma. These changes manifest as endometrial hyperplasia (EH) and endometrial polyps. The objective of this study was to investigate the expressions of ER and Cyclooxygenase-2 (COX2) in EH and endometrial polyps, and determine their correlation with histological and anthropometric parameters. Tissue samples were obtained during hysteroresectoscopy and divided into 3 groups: non-atypical EH, glandular EP, and glandular-fibrous EP. We examined the immunoprofile of epithelial and stromal cells using rabbit polyclonal anti-COX2 antibodies and rabbit monoclonal anti-ER antibodies (clone SP1). Our results indicate that there is no association between the expressions of ER and COX2 and the type of EHP. Furthermore, the expression levels of ER and COX2 are not influenced by the patients anthropometric parameters. However, tissues with EHPs exhibited significantly higher COX2 expression compared to intact tissues. We also observed a direct correlation between ER and COX2 expression in the endometrial epithelium. The variability in ER and COX2 expressions observed in hyperplastic processes of the endometrium potentially suggests their synergistic involvement in the initiation and progression of EHPs, as well as their potential role in subsequent tumor transformation.

Abstract
OBJECTIVE The aim of this study was to compare Ki-67 expression in endometrial polyps that present with different abnormal uterine bleeding patterns. STUDY DESIGN A total of 120 women diagnosed with endometrial polyps were included in the study. In this prospective study, tissue samples taken by hysteroscopic polypectomy method between September 2019 and September 2020 at Bursa City Hospital were examined. The main study groups were determined as premenopausal and postmenopausal patients. The patients' complaints at first admission to the hospital, demographic, histopathological and immunohistochemical features were recorded. RESULTS Ki-67 glandular and stromal expressions were higher in the premenopausal patient group (p = 0.016 and p = 0.005 respectively). Median Ki-67 gland and stroma measurements; was higher in patients with heavy menstrual bleeding (HMB) than in patients with intermenstrual bleeding (IMB), patients with postmenopausal bleeding (PMB), and patients who were asymptomatic [(p = 0.012, p = 0.011 and p = 0.009 respectively); (p < 0.001, p < 0.001 and p = 0.004 respectively)]. The median Ki-67 stroma measurement was found to be higher in the patient group whose complaint persisted after polypectomy (p = 0.034). In the estimation of response to treatment, the cut-off value for Ki-67 stromal expression was determined as ≤ 6%. CONCLUSION High Ki-67 expression in endometrial polyps is associated with HMB and may predict the continuation of abnormal uterine bleeding after polypectomy.

Effect of Hysteroscopic Polypectomy Combined with Mirena Placement on Postoperative Adverse Reactions and Recurrence Rate of Endometrial Polyps: Based on a Large-Sample, Single-Center, Retrospective Cohort Study. BIOMED RESEARCH INTERNATIONAL 2022; 2022:1232495. [PMID: 35528176 PMCID: PMC9071880 DOI: 10.1155/2022/1232495] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 02/25/2022] [Revised: 03/22/2022] [Accepted: 03/28/2022] [Indexed: 11/17/2022]
Abstract
Objective. To investigate the effect of hysteroscopy surgery combined with Mirena on postoperative adverse reactions and recurrence rate of endometrial polyps (EP). Methods. A total of 312 patients who underwent hysteroscopic polypectomy of EP in our hospital from June 2017 to November 2020 were enrolled retrospectively. Among them, 42 patients did not take any treatment after the operation (control group), 156 patients were treated with levonorgestrel intrauterine birth control system (Mirena group), and 114 patients were treated with oral spironolone ethinylestradiol tablets (oral group). The clinical data of 312 patients were recorded and followed up regularly. All patients were followed up through an outpatient clinic or telephone to 12 months after the operation. The patients’ age, disease course, number of pregnancies, clinical manifestations, endometrial thickness before the operation, duration of operation, amount of bleeding during the operation, and number and size of polyps were analyzed. The recurrence and postoperative side effects of EP in the three groups were followed up within 12 months after the operation. Results. There was no significant difference in endometrial thickness among the three groups before treatment (
). After 3 months, 6 months, and 12 months of treatment, the endometrial thickness of the three groups decreased, while the decrease in the Mirena group and the oral group was better compared to the control (
). The decrease in the Mirena group was better than that in the oral group (
). There was no significant difference in hemoglobin levels among the three groups before treatment (
). After 3, 6, and 12 months of treatment, the hemoglobin levels of the three groups increased to varying degrees, while the levels of the Mirena group and oral group were better compared to the control (
). Three months after the operation, the improvement of clinical symptoms was similar in the three groups, and there was no significant difference among the three groups (
). At 6 and 12 months after the operation, the improvement of clinical symptoms in the oral group and Mirena group was better compared to the control group (
), but there was no significant difference between the oral group and Mirena group (
). After the operation, some patients had complications such as lower abdominal pain, breast distension pain, irregular vaginal bleeding, and abnormal liver function. There was no significant difference in the number of complications among the three groups (
). During the follow-up to 12 months after the operation, the recurrence rate in the oral group and Mirena group was lower compared to the control (
), and the recurrence rate in the Mirena group was lower than that in the oral group (
). Conclusion. Placing Mirena immediately after hysteroscopic polypectomy of EP can reduce the recurrence rate of endometrial polyps, increase the level of hemoglobin, and reduce the thickness of the endometrium, which can be employed and popularized according to the condition of patients in clinical work.

Abstract
This review describes cyclooxygenase (COX), which synthesizes prostanoids that play an important role in living things. The authors conducted a national and international literature review on the subject. The COX enzyme uses arachidonic acid to form prostanoids, which play a role in several physiological and pathological conditions. This enzyme has different isoforms, mainly COX-1 and COX-2. The constitutive isoform is COX-1, while COX-2 is the inducible isoform. Both are expressed in different tissues and at different levels, but they may also coexist within the same tissue. Both isoforms show essentially the same mode of action, but their substrates and inhibitors may differ. The COX-1 isoform, which plays a role in the continuation of physiological events, has an increased expression level in various carcinomas, and the COX-2 isoform, which is increased in inflammatory conditions, is typically expressed at low physiological levels in some tissues such as the brain, kidney, and uterus. In addition to investigating the efficacies of the COX-1 and COX-2 isoforms, the discovery of potential new COX enzymes and their effect continues. This review also looks at the roles of the COX enzyme in certain physiological and pathological conditions.

Endometrial polyps: Is the prediction of spontaneous regression possible? Obstet Gynecol Sci 2020; 64:114-121. [PMID: 33321559 PMCID: PMC7834764 DOI: 10.5468/ogs.20242] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2020] [Accepted: 11/05/2020] [Indexed: 12/11/2022] Open
Abstract
Objective Endometrial polyps have been considered as a hyperplastic growth of endometrial stromal and glandular tissues. Even asymptomatic polyps in premenopausal women are usually removed as soon as they are diagnosed, although it is still unknown how often endometrial polyps disappear spontaneously. The aim of this study was to investigate the regression rate of endometrial polyps and the possible factors related to their spontaneous regression. Methods A total of 197 women with endometrial polyps were treated with operative hysteroscopy between January 2017 and April 2019 at our tertiary center. Of these, 123 patients who preferred conservative follow-up were enrolled in the study. Clinical and pathological data were obtained from electronic medical records. Results Patients with endometrial polyps were followed up for a median period of 62 days (range 30–360 days). Most women with endometrial polyps (84%) were reported to have gynecologic symptoms. Spontaneous polyp regression was observed in 28 (23%) patients who underwent surgery reevaluation. Patient age (<45 years), premenopausal period, and polyp size (<2 cm) were found to be associated with spontaneous endometrial polyp regression (P<0.05). We also observed more polyp regression in women with abnormal uterine bleeding (P=0.05). Second-look hysteroscopy showed that all postmenopausal women had persistent endometrial polyps. Conclusion Patient age (<45 years), premenopausal period, polyp size (<2 cm), and abnormal uterine bleeding may be associated with spontaneous endometrial polyp regression.

Abstract
Primary prostate cancer, also known as prostate adenocarcinoma (PCa), is a devastating cancer in men worldwide. Europe and developing countries of Asia have fewer reported cases of prostate cancer compared to increasing cases in the United States with higher incidence in Black men. Risk factors associated with prostate cancer are aging, genetics, lifestyle, high body mass index as well as carcinogenic exposure to carbon-containing fuels, tobacco, and charbroiled meats. Hormone therapy and radical prostatectomy are commonly implemented treatments. The >20.000 prostate cancer deaths of 2013 suggest that there exists a need for enhanced chemopreventive and therapeutic agents for prostate cancer treatment. Fruits, vegetables, and red wines contain high levels of polyphenolic levels. Consumption of these products may provide chemoprevetion of PCa. Curcumin, the major compound from the turmeric rhizome Curcuma longa has long been used for medicinal purposes as an antiseptic and wound healing. This review focuses on curcumin's therapeutic effectiveness in vitro and in vivo in prostate cancer models. The review will highlight the mechanisms of actions of curcumin in the signaling pathways of prostate cancer.

Abstract
OBJECTIVE The aim of the study was to investigate the prevalence of endometrial polyps in patients with uterine fibroids and associated factors of coexistence of these two pathologies. MATERIALS AND METHODS The medical records of 772 patients who underwent hysterectomy because of uterine fibroids were retrospectively reviewed. Patients were divided into two groups according to the presence of endometrial polyps in the histopathologic examination. Demographic, clinical and histopathologic findings of the patients with and without endometrial polyps were compared. Student's t-test, Mann-Whitney U test, Pearson's Chi-square test, and logistic regression analysis were used for statistical analysis. RESULTS The prevalence of the endometrial polyps in uterine fibroid cases was found 20.1% (n=155). Age ≥45 years (odds ratio [OR] 1.61; 95% confidence interval [CI]: [1.06-2.44]; p=0.014), presence of hypertension (23.9% vs. 17.5%; p=0.047), endometrial hyperplasia (OR 4.00; 95% CI: [1.92-8.33]; p<0.001) and cervical polyps (OR 3.13; 95% CI: [1.69-5.88]; p<0.001) were significantly associated with the coexistence of endometrial polyps and uterine fibroids. Endometrial polyps were more common in patients with ≥2 fibroids (p=0.023) and largest fibroid <8 cm (p=0.009). A negative correlation was found between condom use and endometrial polyps (8.1% vs. 3.9%; p=0.044). CONCLUSIONS The prevalence of the endometrial polyps coexisting with uterine fibroids was 20.1%. Age, hypertension, endometrial hyperplasia, cervical polyps, and number of fibroids were positively correlated; condom use and size of largest fibroid were negatively correlated with the coexistence of these two pathologies.
