[PMID: 38694046 PMCID: PMC11061727 DOI: 10.1016/j.heliyon.2024.e30079] [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: 09/12/2023] [Revised: 04/18/2024] [Accepted: 04/18/2024] [Indexed: 05/03/2024] Open
Abstract
Objective To investigate the protective effects against abnormal uterine bleeding (AUB) and possible mechanisms of Xue Ping tablets (XPT) using a rat model. Methods A total of 58 unmated female and 25 male SPF SD rats aged 8-9 weeks were selected. Eight unmated female rats were selected as the blank control group according to the complete random method. The other 50 rats were mated in a female/male ratio of 2:1. In the morning after mating, vaginal smears were collected. Presence of vaginal plug or sperm was regarded as the first day of pregnancy. All pregnant rats were given 8.3 mg/kg of mifepristone by gavage at 8:00 a.m. and 100 μg/kg misoprostol by gavage at 6:00 p.m. on the seventh day of pregnancy to induce incomplete abortion, thereby establishing a rat model of AUB. Forty rats were randomly divided into model, low- (220 mg/kg), medium- (441 mg/kg), high-dose (882 mg/kg) XPT, and positive control groups. The positive group was given 130 mg/kg Gong Xue Ning (GXN). The model group and the blank group were given an equal amount of distilled water. Results Compared with the model group, the volume of bleeding in the positive and middle- and high-dose XPT groups decreased (P < 0.05). Moreover, compared with the model group, the progesterone levels in the positive and XPT groups were significantly increased. Immunohistochemistry showed that XPT significantly decreased the expression levels of VEGF, p-ERK, NF-κB, SAA, MMP-2, MMP-9, TIMP-1, TIMP-2 and TIMP-3. WB results showed that XPT significantly decreased the expression levels of p-ERK, MMP-9, NF-κB, MMP-2 and VEGF. QRT-PCR results showed that XPT significantly decreased the expression levels of VEGF, NF-κB, SAA, MMP-2, TIMP-1, TIMP-2 and TIMP-3 (P < 0.05). Conclusions XPT could reduce AUB by inhibiting the inflammatory factors involved in the VEGF-ERK1/2 pathway.

Abstract
Intrauterine adhesions (IUAs) caused by mechanical damage or infection increase the risk of infertility in women. Although numerous physical barriers such as balloon or hydrogel are developed for the prevention of IUAs, the therapeutic efficacy is barely satisfactory due to limited endometrial healing, which may lead to recurrence. Herein, a second near-infrared (NIR-II) light-responsive shape memory composite based on the combination of cuprorivaite (CaCuSi4 O10 ) nanosheets (CUP NSs) as photothermal conversion agents and polymer poly(d,l-lactide-co-trimethylene carbonate) (PT) as shape memory building blocks is developed. The as-prepared CUP/PT composite possesses excellent shape memory performance under NIR-II light, and the improved operational feasibility as an antiadhesion barrier for the treatment of IUAs. Moreover, the released ions (Cu, Si) can stimulate the endometrial regeneration due to the angiogenic bioactivity. This study provides a new strategy to prevent IUA and restore the injured endometrium relied on shape memory composite with enhanced tissues reconstruction ability.

Abstract
Endometriosis (EM), the presence of functional endometrial glands and stroma outside the uterine cavity, is a common gynecological disorder. At present, the pathogenesis of EM has not been fully elucidated, so there is still a lack of effective therapy. The present study aimed to explore the role of C-C motif chemokine ligand 28 (CCL28) and its underlying mechanism in endometrial stromal cells to propose a novel therapy for EM treatment. The expression of CCL28 and CC chemokine receptor 10 (CCR10) were examined. After CCL28 knockdown or overexpression by lentivirus infection, cell proliferation and invasion were measured. It was revealed that compared with normal, the expression levels of CCL28 and CCR10 were significantly elevated in endometrial tissues of patients with EM. Knockdown of CCL28 in endometrial stromal cells significantly suppressed cell proliferation and invasion, and this was accompanied by significantly reduced expression levels of CCR10, MMP2, MMP9, integrin β1 (ITGB1) and phosphorylated (p)-ERK/ERK ratio. The addition of the CCL28 recombinant protein had an opposite effect to CCL28 downregulation. Furthermore, the ERK inhibitor, PD98059, reduced CCL28-induced cell proliferation and invasion, as well as the expression levels of MMP2, MMP9, ITGB1 and p-ERK. Therefore, the present study indicated that CCL28 may contribute to the progression of EM by regulating MMP2, MMP9 and ITGB1 expression and function via the activation of the ERK signaling pathway.

Abstract
Endometrial cancer is one of the most common gynecological malignancies, yet the molecular mechanisms that lead to tumor development and progression are still not fully established. Matrix metalloproteinases (MMPs) are a group of enzymes that play an important role in carcinogenesis. They are proteases involved in the degradation of the extracellular matrix (ECM) that surrounds the tumor and the affected tissue allows cell detachment from the primary tumor causing local invasion and metastasis formation. Recent investigations demonstrate significantly increased metalloproteinase and metalloproteinase inhibitor levels in patients with endometrial cancer compared to those with normal endometrium. In this review, we aim to show their clinical significance and possible use in the diagnosis and treatment of patients with endometrial cancer. We have critically summarized and reviewed the research on the role of MMPs in endometrial cancer.

Abstract
Background Ferulic acid (FA) and icariin (ICA), as the active compounds derived from Angelica sinensis and Epimedium brevicornum Maxim, respectively, have been shown to promote blood circulation, regulate menstruation, exhibit anti-inflammatory effects, and modulate estrogen levels. The aim of this study was to elucidate the possible mechanism of FA, ICA, and FA-ICA on estrogen-induced mammary gland hyperplasia (MGH) in rats. Methods Hematoxylin and eosin (HE) staining was performed to record the pathological changes in breast tissue, and enzyme-linked immunosorbent assay (ELISA) was utilized to determine the serum levels of luteinizing hormone (LH), PRL (prolactin), testosterone (T), estradiol (E2), follicular stimulating hormone (FSH), and progesterone (P). The message RNA (mRNA) expression levels of extracellular signal-regulated kinase 1 (ERK1), extracellular signal-regulated kinase 2 (ERK2), estrogen receptor (ER), and progesterone receptor (PR) were detected by real-time reverse transcription-polymerase chain reaction (RT-PCR) analysis. Furthermore, ER, phosphorylated-ER, PR, p-PR, ERK1/2, and p-ERK1/2 protein factors in the ERK signaling pathway were evaluated by Western blotting. Simultaneously, changes in breast height, diameter, body weight, and organ index were all recorded. Results We found that FA and ICA could modulate the degree of breast swelling, and reduce the body weight, thymus index, and uterus index. Furthermore, it could also block the pathological changes of MGH, including the number of mammary lobules, and the proliferation or expansion of acini and ducts. Moreover, treatment with FA and ICA remarkably down-regulated the serum expression levels of LH, PRL, T, and E2, as well as the mRNA expression levels of ERα, PR, ERK1, and ERK2. Additionally, protein levels of ERα, p-ERα, PR, p-PR, ERK1/2, and p-ERK1/2 in breast tissue were down-regulated, however the serum content of FSH and P was up-regulated. Conclusions Our outcomes revealed that FA and ICA might potentially inhibit ERα, PR, ERK1/2, and their phosphorylated proteins via the ERK signaling pathway, thus indicating a positive feedback control for the degree of breast hyperplasia.

Abstract
The bone marrow (BM) vascular niche microenvironments harbor stem and progenitor cells of various lineages. Bone angiogenesis is distinct and involves tissue-specific signals. The nurturing vascular niches in the BM are complex and heterogenous consisting of distinct vascular and perivascular cell types that provide crucial signals for the maintenance of stem and progenitor cells. Growing evidence suggests that the BM niche is highly sensitive to stress. Aging, inflammation and other stress factors induce changes in BM niche cells and their crosstalk with tissue cells leading to perturbed hematopoiesis, bone angiogenesis and bone formation. Defining vascular niche remodeling under stress conditions will improve our understanding of the BM vascular niche and its role in homeostasis and disease. Therefore, this review provides an overview of the current understanding of the BM vascular niches for hematopoietic stem cells and their malfunction during aging, bone loss diseases, arthritis and metastasis.

Abstract
Vascular endothelial growth factor (VEGF) is the most important regulator of angiogenesis which serves to provide sufficient blood supply, and can trigger both physiological and pathological angiogenesis. Recent studies have shown that VEGF increases in gynecological diseases (such as endometriosis, ovarian, and endometrial cancers) and is a prognostic factor in these pathologies. Therefore, VEGF should be maintained at appropriate levels. Magnesium is used in many gynecological practices (such as eclampsia, preeclampsia, dysmenorrhea, and climacteric symptoms) and the mechanisms of action are still under investigation. Redox status, which can be regulated by magnesium, was shown to affect VEGF expression. The aim of this study was to evaluate the effects of chronic magnesium use on VEGF and oxidative status in the uterus. Magnesium sulfate was administered to rats at doses of 30 mg/kg (intramuscular) for 2 weeks. VEGF, Superoxide dismutase (SOD), Glutathione peroxidase (GPx), and Malondialdehyde (MDA) levels were measured using ELISA; vascular and cellular alterations were determined by histology in the uterine tissue at the metoestrus phase. In the uterine tissue of Mg-treated subjects, magnesium levels increased while VEGF, SOD, GPx, and MDA levels decreased without histological changes. There was a negative correlation between uterine tissue magnesium levels and VEGF, SOD, GPx, and MDA levels. Consequently, the results of this study demonstrated that regular magnesium use decreased VEGF levels in uterus. Decreased VEGF levels were associated with decreased uterine oxidative stress. Chronic magnesium usage may protect the uterine tissue from certain diseases in which angiogenesis is critical.

Abstract
The study aimed to investigate the antitumor effects of Trapa acornis husks (TAH) extract on SK-BR-3 cells of Her2-positive breast cancer. The bioactive compounds of TAH extracts were analyzed qualitatively and quantitatively by Ultra-Performance Liquid Chromatography/Mass Spectrometry (UPLC-MS)/high-performance liquid chromatographic system (HPLC). The effects of TAH extracts on cell proliferation, cell cycle, and apoptosis of SK-BR-3 cells were determined by CCK-8 and flow cytometry. Besides, the In Vivo antitumor effect of TAH extracts was detected. UPLC-MS/HPLC showed that the main bioactive compounds of TAH were gallic acid and galloylglucose derivatives. TAH extracts significantly inhibited the proliferation of SK-BR-3 cells in a dose- and time-dependent manner (P < 0.01). With the increase of TAH extracts concentration, cells in G2/M stage were increased and cell apoptosis was significantly increased. Immunohistochemical analysis showed that TAH extracts can significantly reduce the positive expression rate of Ki67 and Factor VIII index in tumor tissues. The mRNA expression levels of VEGF, MMP2, MMP9, and uPA were reduced after TAH extracts intervention (P < 0.01). TAH extracts also decreased the protein expression of p-Her2, p-ERK1/2, VEGF, MMP2, MMP9, and uPA (P < 0.01). In conclusion, polyphenol-enriched extracts from TAH might inhibit breast cancer cell proliferation and In Vivo tumor angiogenesis.

Abstract
Background Vascular development, including vasculogenesis and angiogenesis, is involved in many diseases. Cystatin C ( CST 3) is a commonly used marker of renal dysfunction, and we have previously reported that its expression level is associated with variations in the gerbil circle of Willis. Thus, we hypothesized that CST 3 may affect endothelial function and angiogenic capacity. In the current study, we sought to determine the influence of CST 3 on endothelial function and explore its potential regulatory pathway. Methods and Results We analyzed CST 3 and vascular endothelial growth factor A ( VEGFA) levels in different developmental stages of gerbils using ELISA s and immunofluorescence (to examine the relationship between CST 3 and VEGFA . We used a real-time cell analyzer, cytotoxicity assays, and the chorioallantoic membrane assay to investigate the function of CST 3 in endothelial cells and the chorioallantoic membrane. Additionally, we used Western blotting to explore the downstream targets of CST 3. The expression levels of both CST 3 and VEGFA were at their highest on day 10 of the embryonic stage. CST 3 inhibited endothelial cell proliferation, migration, tube formation, and permeability, as well as vascular development in the chorioallantoic membrane. Blocking of VEGFA dose-dependently increased CST 3 expression in arterial and venous endothelial cells. Furthermore, overexpression and knockdown of CST 3 significantly affected the protein levels of p53 and CAPN10 (calpain 10), suggesting that CST 3 might play a role in vascular development through these proteins. Conclusions CST 3 may be associated with vascular development and angiogenesis, and this effect could be promoted by blocking VEGFA .

In this study, we showed the beneficial effects of casticin on the inhibition of prostate cancer cell metastasis. Casticin reduced total viable cell number, thus, we selected low doses of casticin for following experiments. Casticin decreased cell mobility, suppressed cell migration and invasion, and reduced cell gelatinolytic activities of MMP-2/-9. Furthermore, casticin inhibited the protein levels of AKT, GSK3 αβ, Snail, and MMPs (MMP-2, -9, -13, and -7) at 24 and 48 hr treatment. Casticin diminished the expressions of NF-κB p65, GRB2, SOS-1, MEK, p-ERK1/2, and p-JNK1/2 at 48 hr treatment only. However, casticin reduced the level of E-cadherin at 24 hr treatment but elevated at 48 hr. The novel findings suggest that casticin may represent a new and promising therapeutic agent for the metastatic prostate cancer. PRACTICAL APPLICATIONS: Casticin derived from natural plants had been used for Chinese medicine in Chinese population for thousands of years. In the present study, casticin attenuated metastatic effects, including decreasing viable cell number, inhibiting the migration, invasion, and adhesion, and reducing matrix metalloproteinases activity on human prostate DU 145 cancer cells. In addition, the results also provided possible pathways involved in casticin anti-metastasis mechanism. We conclude that casticin may be an aptitude anticancer agent or adjuvant for the metastatic prostate cancer in the future.

Abstract
AIM To analyze the effects of high ovarian response on endometrial collagen synthesis and related gene expression during the peri-implantation period in patients undergoing in vitro fertilization-embryo transfer. METHODS Peripheral blood and endometrial biopsies were obtained from infertile women on day 6 after oocytes retrieval or ovulation in 16 stimulated cycles (SC) and 16 natural cycles (NC) respectively. Serum estrogen (E2 ), progesterone (P4 ), histological staging, endometrial collagen, matrix metalloproteinases (MMP2, 9) and tissue inhibitors of metalloproteinases (TIMP1, 3) were assayed. RESULTS Serum levels of both E2 and P4 were significantly higher in the SC group than those in the NC group. All endometrial samples were in the secretory phase. The collagen in the stroma of the SC group was more dense and higher than that in the NC group. MMP2 and MMP9 were detected significantly lower in the SC group than those in the NC group, while TIMP1 and TIMP3 were significantly higher. MMP2, 9 expressions are increased by estrogen and reduced by progesterone in dose-dependent manner through estrogen receptor and progesterone receptor. Correspondingly, TIMP1, 3 expressions decreased by estrogen dose-dependently while progesterone played the opposite role. CONCLUSION High levels of P4 could stimulate excessive synthesis of collagen in peri-implantation endometrium of women with high ovarian response, and the mechanisms may be related to the decrease of MMP2, 9 and the increase of TIMP1, 3 through P4 receptor.

Abstract
Aberrant regulation of matrix metalloproteinases (MMPs) may be the primary cause of endometrial lesion formation in a group of predisposed women. Prospect for the genuine origin of endometriosis is ongoing, since retrograde menstruation leads to presence of endometrial debris in peritoneal cavity of many women, which do not experience endometriosis. Tissue remodeling is regulated precisely by a balance of MMPs and their inhibitors. Interplay between factors enhancing and suppressing matrix turnover is crucial for cyclic preparation of endometrium for embryo implantation, and endometrial shedding and renewal in physiology of primates. Disorders of the regulation of matrix remodeling leads to augmentation of implantation and invasive growth of ectopic endometrial tissue. Moreover, endometriosis-induced changes in the matrix balance leads to adhesion formation, ovulatory dysfunction and fertility impairment. The review summarizes the current knowledge regarding the regulation of extracellular matrix turnover in the physiology of the endometrial cycle and in the development of endometriosis, as well as the pathophysiology of ovulatory dysfunction in endometriotic women. Therapeutic modalities utilizing modulation of tissue remodeling were discussed.

Abstract
OBJECTIVE Matrix metalloproteases (MMPs), particularly MMP2 and MMP9 increase tumor invasion and edema in meningiomas. Although lesser recognized, MMPs may also enhance cell growth via liberating growth factors or via cleaving inactive growth factors into active isoforms. However, there exist very few studies, which investigated correlation of MMPs with growth fraction in meningiomas. Meningiomas are seen more frequently in women and their growth accelarate during pregnancy. However, no study examined whether MMP-expressions in meningioma differ with gender. PATIENTS AND METHODS In a pilot immunohistochemical study, we analyzed the correlation of MMP9 expression with Ki67 index and whether gender influences MMP9 expression. We retrospectively selected 24 meningioma cases including 10 cases with WHO Grade-1 tumors and 7 cases each with WHO Grade-2 and 3 tumors, respectively. RESULTS We separately determined the intensity and area of MMP9 staining and also calculated an expression index by multiplying these two parameters. Spearman correlation analyses revealed that MMP9 staining intensity, staining area and expression index significantly correlated with Ki67 proliferation index. MMP9 staining indices were significantly higher in women specimens. CONCLUSION If these findings will be confirmed in larger series, MMP-inhibitors and female hormone receptor-antagonists may be combined to augment chemotherapy efficacy and to attenuate invasion in high-grade meningiomas.

Abstract
Deguelin, a rotenoid, is isolated from a natural plant species, and has biological activities including antitumor function. In the present study, we investigated the effect of deguelin on the cell adhesion, migration and invasion of NCI-H292 human lung cancer cells in vitro. Cell viability was analyzed by using flow cytometer. Cell adhesion was determined by using the cell-matrix adhesion assay. Wound healing assay was used to examine cell migration. Cell migration and invasion were investigated using a Boyden chamber assay. The protein expression was measured by Western blotting and confocal laser microscopy. The electrophoretic mobility shift assay was used to measure NF-[Formula: see text]B p65 binding to DNA.We selected the concentrations of deguelin at 0, 0.5, 1.0, 1.5, 2.0 and 2.5[Formula: see text][Formula: see text]M and we found that those concentrations of deguelin did not induce significant cytotoxic effects on NCI-H292 cells. Thus, we selected those concentrations of deguelin for metastasis assay. We found that deguelin inhibited cell adhesion, migration and invasion in dose-dependent manners that was assayed by wound healing and transwell methods, respectively. Deguelin decreased the expression of MMP-2/-9, SOS 1, Rho A, p-AKT (Thr308), p-ERK1/2, p-p38, p-JNK, NF-[Formula: see text]B (p65) and uPA in NCI-H292 cells. Deguelin suppressed the expression of PI3K, SOS 1, NF-[Formula: see text]B (p65), but did not significantly affect PKC and Ras in the nuclei of NCI-H292 cells that were confirmed by confocal laser microscopy. We suggest that deguelin may be used as a novel anticancer metastasis of lung cancer in the future.

Abstract
Mammary gland hyperplasia (MGH) is a pathological condition that affects the majority of women at the child-bearing stage. The hormone and endocrinal therapy are typically used to treat MGH. Nevertheless, there are still some certain side effects accompanied with the benefits, which negatively affect the life quality of patients. Therefore, plant-derived agents that are effective against MGH development and with fewer side effects should be developed. The aim of this study was to investigate the protective effects and underlying mechanism of total saponins of Phytolaccae (TSP) against MGH in vivo. The results showed that treatment with TSP could significantly correct the disorder of serum sex hormones levels in rats with MGH, and eliminate the formation of MGH. Moreover, TSP significantly protected estrogen and progesterone-induced MGH histological changes, inhibited the swelling of the nipple, and improved the organ coefficient of uterus in rats with MGH. Mechanistically, TSP treatment not only effectively suppressed the mRNA and protein expression of ERα and PR in mammary gland, but also simultaneously up-regulated ERβ expression, and thus blocked sex hormones from interacting with their receptors. TSP treatment markedly suppressed mammary phosphorylation levels of ERK1/2, as well as reduced the mRNA and protein overexpression of VEGF and bFGF in mammary of rats. In addition, TSP treatment substantially down-regulated the expression of Bcl-2 and Ki-67, as well as elevated the expression of Bax. These findings indicated that TSP could potentially be used for effective treatment of MGH.

Abstract
OBJECTIVE Vaginal mesh exposure is the most common complication from mesh use in prolapse and incontinence surgery. Angiogenesis is an essential component of tissue healing, and defective angiogenesis plays a role in chronic wounds. We hypothesized that patients with exposures will have impaired angiogenesis as evidenced by altered tissue vascular endothelial growth factor A (VEGFA) expression and microvessel density. The study objective was to compare angiogenesis in women with vaginal mesh exposures, those with vaginal mesh without exposures, and in women who were mesh-naive. METHODS Patients undergoing polypropylene mesh removal and patients without mesh undergoing urinary incontinence or prolapse surgery were recruited. Full-thickness vaginal epithelial biopsies were obtained. The relative abundance of VEGFA RNA was measured with reverse transcription-polymerase chain reaction. The VEGFA and CD31 immunohistochemistry were also performed. RESULTS Ninety-two subjects were enrolled and biopsied. Mean age (SD) was 57.2 (12.8) years, 16 (17.4%) were smokers, and 68 (73.9%) were postmenopausal.The VEGFA RNA expression did not differ between subjects with mesh exposure and with mesh but no exposure (P = 0.89). However, compared with subjects with no mesh, vaginal VEGFA expression was decreased in subjects with any implanted mesh (relative expression, 0.72; P = 0.02). Microvessel density was increased in subjects with mesh exposure compared with subjects with no mesh (P < 0.01). The VEGFA expression by immunohistochemistry was significantly lower in postmenopausal subjects without estrogen treatment compared with premenopausal and postmenopausal subjects being treated with estrogen (P = 0.02). CONCLUSIONS The presence of polypropylene mesh and hormonal status are associated with evidence of altered angiogenesis.

Abstract
Changes in endometrial cell morphology and function are absolutely necessary for successful embryo implantation. In this study, miR-26a was widely expressed in dairy goats, and was found to be regulated by β-estradiol (E2) and progesterone (P4) in endometrial epithelium cells (EECs) as well as stromal cells (ESCs). Furthermore, miR-26a played a role in the regulation of cells proliferation and apoptosis by directly regulating PTEN and indirectly regulating the PI3K/AKT pathway in EECs but not in ESCs of dairy goats in vitro. In addition, miR-26a regulated the expression of osteopontin (OPN), vascular endothelial growth factor (VEGF), Cyclooxygenase-2 (COX-2), and prolactin (PRL) in endometrial cells. Therefore, we could get a conclusion that miR-26a had very complex and diverse functions in the endometrial cells during the development of endometrial receptivity in dairy goats. This study provided an efficient platform for studying the regulatory effect of miR-26a on endometrial cells during the development of endometrial receptivity in dairy goats.

Abstract
The aim was to obtain experimental evidence of cervical collagen degradation in anoestrous Corriedale adult ewes induced to ovulate with progesterone (P) and gonadotrophin-releasing hormone (GnRH), at the expected time of induced ovulation and early luteal phase. In Experiment 1, anoestrous ewes were treated with P for 10 days (P, n = 4), with nine micro-doses of GnRH followed by a GnRH bolus injection (GnRH, n = 4) or with P plus GnRH treatments (P+GnRH, n = 3), and cervices were obtained either without treatment (A, n = 4), when P was removed, or 24 h after the GnRH bolus injection. In Experiment 2, cervices were obtained 1 (group P+GnRH, n = 5) or 5 (P+GnRH 5, n = 6) days after the GnRH bolus injection with P pretreatment. MMP-2 activity was detected in all samples; however, MMP-9 activity was only detected in 15% of the samples. The activity of the latent (L) form of MMP-2 in the cranial zone of group A was higher than in the cranial zone of groups P, GnRH and P+GnRH, and was also higher than that in the caudal zone of the same group (P < 0.05). The collagen concentration was lower in group P+GnRH 1 than in group P+GnRH 5 (P < 0.04). The activity of the activated (A) form of MMP-2 and the A/L MMP-2 ratio were higher in group P+GnRH 1 than in group P+GnRH 5 (P < 0.05). Data suggest that the L form of MMP-2 was expressed mainly in a constitutive form in the cervix of anoestrous ewes and that an oestrogen-dependent activation mechanisms due to the GnRH treatment may be responsible for the lowest collagen content at the moment of the induced ovulation. This work provides evidence about cervical collagen remodelling in anoestrous ewes treated with P + GnRH.

Abstract
Angiogenesis (the growth of new blood vessels) is essential in most of the body’s physiological processes, such as in the normal functioning of the endometrium during and after the menstrual cycle. Vascular endothelial growth factor (VEGF) and matrix metalloproteinase (MMP) are the mostly expressed angiogenic factors, especially, during the process of endometrial degeneration and remodeling. In carcinogenesis, tumor hypoxia-induced factors, through the process of “angiogenic switch”, stimulate the production of angiogenic factors, particularly VEGF and MMP. Subsequently, these angiogenic factors are associated with degradation, differentiation, proliferation, and migration of vascular endothelial cells, enhancing the formation of new blood vessels to supply the tumor with oxygen and nutrients. This process is equally significant for tumor development and metastasis. Hence, like in other cancers, the overexpression of MMP and VEGF in endometrial cancer (EC) seems to play a significant role in its tumorigenesis and metastasis. This research will discuss the influence of MMP and VEGF on angiogenesis, metastasis, and the prognosis of EC as well as the clinical importance of the factors in the diagnosis of EC.

Abstract
Mammary gland hyperplasia (MGH) occurs with high frequency among middle-aged women and is closely related to breast cancer. The treatment of this disease has become a research hotspot. Many patients with MGH are worried about the potential side effects of the synthetic drugs they are on. Thus, they seek alternative therapy, such as traditional Chinese medicine (TCM). In recent years, along with the Chinese herbs and its active ingredients, TCM compounds have been widely accepted and implemented in the treatment of MGH, whose mechanism hitherto is not completely clear. In this paper, we elaborate the mechanism of TCM in the treatment of MGH from the perspectives of sexual hormone levels, the expression of ER and PR, hemorheology, free radical activity and lipid peroxidation, VEGF and BFGF, cell proliferation activities, anti-apoptosis gene BcL-2, promoting apoptosis gene Bax, ERK, and tumor suppressor gene. In conclusion, TCM appears to be promising for MGH treatment. This paper will provide an overview of the mechanism of TCM in the treatment of MGH. In the near term, a better understanding of TCM will be achieved through comprehensive studies of its molecular mechanism.

Abstract
OBJECTIVE To investigate the effect of radiotherapy plus recombinant human endostatin (RH-endostatin) on esophageal cancer and its mechanism. METHODS A total of 50 nudemice were equally randomized into control group, radiotherapy group, and combined therapy group I, II, and III after inoculating with Eca109 cell suspension (1 × 10(7) cells/mL). On the day of grouping, control group and radiotherapy group were injected normal saline, while radiotherapy group and 3 combined therapy groups received radiotherapy; besides, combined therapy group I, II, and III was injected RH-endostatin of 2.5, 5, 10 mg/kg respectively. After 3-week therapy, the tumors of each group were collected and microvessel density and VEGF expression in tumors were determined. In vitro, Eca109 cells were divided into control group, radiotherapy group, and combined therapy group. Forty-eight hours after treatment, cell cycle distribution and apoptosis rate were detected, and the activity of VEGF signal paths was semiquantitatively analyzed. RESULTS Since the 6th day of treatment, the relative tumor proliferation rate of combined therapy group II was lower than radiotherapy group (P < 0.05) and ≤40% since the 15th day. Average microvessel density and EGFR expression in combined therapy group II were lower than radiotherapy group (P < 0.05). In vitro, the cell percentage in S and G2/M phase of combined therapy group cells was lower than that in radiotherapy group cells, while the apoptosis rate and the expression of VEGF, AKT, p-AKT, ERK1/2 and p-ERK1/2 in combined group were higher than that in radiotherapy group (P < 0.05). CONCLUSIONS RH-endostatin promotes the efficacy of radiotherapy on esophageal cancer, which may be partly realized by inhibiting the activity of VEGF related signal paths.

Abstract
Several previous studies including one of them co-authored by our group have revealed that serum and psoriatic plaque expression of matrix metalloproteinase-9 (MMP-9) was significantly upregulated in psoriasis. The aim of this study was to investigate the association of three single nucleotide polymorphisms (SNPs) and haplotypes of MMP-9 (rs3918242, rs3918254 and rs4810482) with psoriasis vulgaris in a Chinese Han population. The serum levels of MMP-9 in 245 psoriasis vulgaris cases and 256 healthy controls were assessed using ELSA kits, and the three SNPs were genotyped using polymerase chain reaction-ligation detection reaction (PCR-LDR) method. Four haplotypes based on the three SNPs were also analyzed. Our study showed that the serum MMP-9 levels in patients with psoriasis vulgaris were significantly higher than that in controls (P<0.05). However, the three SNPs were not significantly associated with psoriasis vulgaris susceptibility (all P>0.05). Similar results were found in further subgroup analysis based on gender, age of onset, family history, and serum MMP-9 levels, except that a protective effect of psoriasis vulgaris was detected among female subjects with the CT genotype of rs3918254 (OR=0.47, 95% CI=0.23-0.96, P=0.038), but this association did not survive after Bonferroni correction (P(adj)=0.076). The haplotype analysis also failed to show any association with psoriasis vulgaris. We found no evidence for the association between the MMP-9 polymorphisms and psoriasis vulgaris susceptibility in a Chinese Han population.

Estrogen receptor (ER)-α, β and progesterone receptor (PR) mediates changes in relaxin receptor (RXFP1 and RXFP2) expression and passive range of motion of rats' knee. ENVIRONMENTAL TOXICOLOGY AND PHARMACOLOGY 2015; 40:785-791. [PMID: 26447688 DOI: 10.1016/j.etap.2015.09.004] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/27/2015] [Revised: 09/04/2015] [Accepted: 09/05/2015] [Indexed: 06/05/2023]
Abstract
PURPOSE The high risk of knee injuries in female may be associated with sex-steroid hormone fluctuations during the menstrual cycle by its effect on ligaments and tendons stiffness. This study examined changes in knee range of motion in presence of estrogen and progesterone and investigated the interaction of their antagonists to relaxin receptors. METHOD Sixty WKY rats were divided into 10 different groups receiving 17β-estradiol (0.2, 2, 20 and 50 μg/kg), progesterone (4 mg/kg), estrogen receptor (ER) antagonist ICI 182/780, ERβ antagonist PHTPP, ERα antagonist MPP, and mifepristone in presence of estrogen and progesterone. Physiologic dose were injected subcutaneously 30 min before of hormone injection for 3 days consequently. Sham group received peanut oil (vehicle) also for 3 consecutive days. Following the treatment administrations, the knee range of motion and RXFP1/RXFP2 mRNA and protein expression were examined in the patellar tendon, lateral collateral ligament, and hamstring muscle. RESULTS Our data showed that the knee range of motion was significantly increased in progesterone and high doses estrogen treatment but not significantly increased in low doses of estrogen treatment. The range of motion was decreased in the presence of estrogen receptor (ER) antagonist ICI 182/780, ERβ antagonist PHTPP, ERα antagonist MPP, and mifepristone, independently. CONCLUSION Progesterone and high doses of estrogen treatment resulted in the highest range of knee laxity correlated to expression of both relaxin receptor isoforms in knee tissues. Our findings thus suggested that female subjects are more vulnerable toward non-traumatic knee injury due to estrogen and progesterone fluctuation as compared to male subjects.

Abstract
OBJECTIVES To describe the effect of combined oral contraceptives (COCs) on matrix metalloproteinases MMP-2 and MMP-9 activity and compare MMP activity in women taking a COC with or without doxycycline. STUDY DESIGN Subjects (n=20) underwent endometrial biopsies (1) in the late luteal phase of a baseline cycle prior to initiating COCs, (2) on days 19-21 while taking COCs in a standard 28-day cycle (7-day hormone-free interval) and (3) on days 26-28 while taking active COCs continuously for a 28-day cycle. During the continuous COC cycle, they were randomized to receive daily subantimicrobial dose doxycycline 40mg or placebo. RESULTS Compared to baseline, COC treatment increased MMP-2 (p<.001) and MMP-9 (p<.001). MMP activity was lower in subjects taking a COC with doxycycline compared to those receiving placebo although only significantly lower for MMP-2 latent form (p=.002). CONCLUSIONS Unscheduled bleeding with COCs may be the result of increased endometrial MMPs. Sample size limitations prevent us from determining how doxycycline affects MMP activity in COC users.

Abstract
Neuropilin 1 (NRP1), a receptor of vascular endothelial growth factor (VEGF), promotes angiogenesis, tumor growth, tumor invasion and metastasis. However, the function of NRP1 in melanoma progression, as well as the effect of NRP1 expression on the prognosis of patients with melanoma remains unknown. In the present study, NRP1 expression was examined in 460 cases of melanocytic lesions (28 common nevi, 51 dysplastic nevi, 250 primary melanoma and 131 metastatic melanoma) at different stages, using a tissue microarray. The correlation of NRP1 expression with melanoma progression, and its prognostic value in patients with melanoma was examined. In addition, the correlation between matrix metalloproteinase 2 (MMP2) and NRP1 expression in patients with melanoma was analyzed. The results demonstrated that NRP1 expression was significantly increased in primary (56%) and metastatic melanoma (62%), compared with common nevi (11%) and dysplastic nevi (24%). Notably, increased NRP1 expression was correlated with a poorer overall, and disease-specific, 10-year survival (P=0.03 and P=0.002, respectively). Multivariate Cox regression analyses indicated that NRP1 is an independent prognostic marker for melanoma. Furthermore, a significant positive correlation between NRP1 and MMP2 expression in melanoma biopsies was observed, and their concomitant expression was closely correlated with melanoma patient survival, further supporting the hypothesis that the expression of NRP1 is associated with melanoma invasion and metastasis. In conclusion, increased NRP1 expression is associated with disease progression and reduced survival in patients with melanoma, and is a promising prognostic molecular marker for this disease.

Abstract
Angiogenesis plays an important role in cancer growth, invasion and metastasis. It has been confirmed that metadherin (MTDH) is associated with angiogenesis. However, the detailed mechanism of MTDH on angiogenesis has not yet been reported. In this study, we demonstrate the anti-angiogenic function of MTDH in breast cancer. With RNA interference strategies, we found that knockdown of MTDH inhibits cellular angiogenesis both in vitro and ex vivo. Furthermore, we revealed that ERK1/2 pathway is involved in the anti-angiogenic function of MTDH, and the function can be partially reversed via upregulation of microRNA-21 (miR-21). In conclusion, knockdown of MTDH can inhibit angiogenesis in breast cancer. These results show that MTDH is a viable therapeutic target for anti-angiogenesis in breast cancer.

Abstract
Numerous epidemiological and experimental animal studies have indicated that chronic psychological stress may promote tumor development. However, the underlying molecular mechanisms by which chronic stress promotes tumorigenesis remain to be fully elucidated and animal models have not yet been well established. In the present study, an established mouse model of repeated social defeat stress (RSDS), was generated and used to investigate the effect of stress on tumor growth and metastasis. C57BL/6 mice were exposed to RSDS for 10 days, followed by subcutaneousl inoculation with Lewis lung carcinoma cells for seven days. The tumor weight and volume as well as the number of the lung metastatic nodules were then determined. Vascular endothelial growth factor (VEGF) serum levels were measured using ELISAs. In addition, expression levels of VEGF receptor (VEGFR) and L1 cell adhesion molecule (L1CAM) messenger (m)RNA were confirmed using reverse transcription quantitative polymerase chain reaction. Furthermore, protein expression levels of phosphorlyated extracellular signal-regulated kinase (pERK), matrix metalloproteinase (MMP)-2 and MMP-9 were examined using western blot analysis. The results showed that RSDS significantly increased the weight and the volume of the primary tumor as well as the number of the lung metastatic nodules. Serum VEGF levels were significantly higher in the tumor-stress group compared with those of the unstressed tumor mice. In addition, tumors in stressed animals demonstrated markedly enhanced expression of VEGFR-2 and L1CAM mRNA as well as pERK, MMP-2 and MMP-9 protein expression. In conclusion, these results suggested that RSDS contributed to lung cancer progression, angiogenesis and metastasis, which was partially associated with increased VEGF secretion and therefore the activation of the ERK signaling pathway, resulting in the induction of MMP-2 and MMP-9 protein expression.

Abstract
Background Kaempferol has been proposed as a potential drug for cancer chemoprevention and treatment because it is a natural polyphenol contained in plant-based foods. Recent studies have demonstrated that kaempferol protects against cardiovascular disease and cancer. Based on this finding, we investigated the mechanisms by which kaempferol produces the anti-metastatic effect in human tongue squamous cell carcinoma SCC4 cells. Methodology/Principal Findings In this study, we provided molecular evidence associated with the anti-metastatic effect of kaempferol by demonstrating a substantial suppression of SCC4 cell migration and invasion. This effect was associated with reduced expressions of MMP-2 and TIMP-2 mRNA and protein levels. Analysis of the transcriptional regulation indicated that kaempferol inhibited MMP-2 transcription by suppressing c-Jun activity. Kaempferol also produced an inhibitory effect on the phosphorylation of ERK1/2. Conclusions These findings provide new insights into the molecular mechanisms involved in the anti-metastatic effect of kaempferol, and are valuable in the prevention of oral cancer metastasis.
