Abstract
MicroRNAs (miRNAs) play critical roles in the development of vascular diseases. However, the effects of miR-130a-5p and its functional targets on atherosclerosis (AS) are still largely unknown. In this regard, our aim is to explore the potentially important role of miR-130a-5p and its target gene during the progression of endothelial cell injury. We first found oxidized low-density lipoprotein (ox-LDL) induced FAS and cell apoptosis in HUVECs. Subsequently, miR-130a-5p expression was verified to be downregulated after ox-LDL treatment and negatively correlated with FAS, and FAS was identified as substantially upregulated in the ox-LDL-treated HUVEC cells. After that, the knockdown of FAS and overexpression of miR-130a-5p together were observed to aggregate ox-LDL-induced reduction of cell viability and apoptosis, cell cycle progression, cell proliferation, cell migration and invasion. In conclusion, we detected that miR-130a-5p contributed to the progression of endothelial cell injury by regulating of FAS, which may provide a new and promising therapeutic target for AS.

Abstract
The long non-coding FGD5-AS1 (LncFGD5-AS1) has been reported to be a novel carcinogenic gene and participant in regulating tumor progression by sponging microRNAs (miRNAs). However, the pattern of expression and the biological role of FGD5-AS1 in hepatocellular carcinoma (HCC) remains largely unknown. The expression level of FGD5-AS1 in tumor tissues and cell lines was measured by RT-qPCR. CCK-8, EdU, flow cytometry, wound healing and transwell chamber assays were performed to investigate the role of FGD5-AS1 in cell proliferation, apoptosis, migration, and invasion in HCC. Dual luciferase reporter, and RNA pull-down assays were performed to identify the regulatory interactions among FGD5-AS1, miR-873-5p and GTP-binding protein 4 (GTPBP4). We found that the expression of FGD5-AS1 was upregulated in HCC tissues and cell lines. Moreover, the knockdown of FGD5-AS1 suppressed cell proliferation, migration and invasion, and induced apoptosis in HCC cells. Further studies demonstrated that FGD5-AS1 could function as a competitive RNA by sponging miR-873-5p in HCC cells. Moreover, GTPBP4 was identified as direct downstream target of miR-873-5p in HCC cells and FGD5-AS1mediated the effects of GTPBP4 by competitively binding with miR-873-5p. Taken together, this study demonstrated the regulatory role of FGD5-AS1 in the progression of HCC and identified the miR-873-5p/GTPBP4 axis as the direct downstream pathway. It represents a promising novel therapeutic strategy for HCC patients.

Abstract
Background MicroRNAs (miRNAs) often appear as oncogenes or tumor suppressor genes. The aim of this research was to examine miR-132-3p and Kruppel-like factor 7 (KLF7) effects in the development of non-small cell lung cancer (NSCLC). Methods We used quantitative reverse transcription polymerase chain reaction (qRT-PCR) to determine miR-132-3p expression in tissue specimens and 6 cells (A549, H1650, H292, H1299, H1944, BEAS-2b). Luciferase report forecasted the targeting relationship between miR-132-3p and KLF7. The expression of KLF7 and interstitial protein was determined by western blot. Proliferation test and Transwell assay were adopted for examining cell development. The Cell Counting Kit-8 (CCK-8) colorimetric method was used to observe the effects of miR-132-3p and KLF7 on the proliferation, metastasis, and invasion of NSCLC tumor cells. In order to determine whether the metastasis of NSCLC tumor cells was epithelial-mesenchymal transition (EMT)-mediated, supplementary experiments with E-cadherin and vimentin were performed. Results An increased expression of miR-132-3p was detected in NSCLC. Its mimic promoted the proliferation of tumor cells. As an immediate site of miR-132-3p, KLF7 was reversely adjusted via miR-132-3p and restrained the development of tumor cells in NSCLC, the effects of which were attenuated via KLF7 over-expression. Besides, the presence of EMT-related diversions was confirmed in NSCLC. Conclusions By targeting KLF7, miR-132-3p was capable of promoting the proceeding of NSCLC tumor cells. We discovered miR-132-3p/KLF7 route may exhibit curative target for NSCLC.

Abstract
Ovarian cancer (OC) has a high mortality rate among women worldwide. However, even with the advances in detection and therapeutics, the number of cases is increasing worldwide. Increasingly, microRNAs (miRNAs), including miR-497-5p, have been implicated in the progression of many cancers, but the role of miR-497-5p in OC remains unknown. The purpose of this study was to investigate the underlying molecular mechanism of miR-497-5p in OC. Herein, we find that miR-497-5p is down-regulated in OC tissues, and overexpression of miR-497-5p enhances apoptosis in OC cells. The increased apoptosis was correlated with enhanced expression of apoptosis-related proteins. MiR-497-5p directly bound the 3'-untranslated region of metadherin (MTDH), leading to the reduction of MTDH in mRNA and protein levels. Moreover, MTDH knockout promoted the apoptosis of OC cells. Taken together, we conclude that miR-497-5p contributes to cell apoptosis in OC by regulating MTDH.

Abstract
Ovarian cancer (OC) is the one of the most common cancer in women globally. However, it still represents the most dangerous gynecologic malignancy even with the advances in detection and therapeutics. Thus, there is an urgent need in finding more effective therapeutic options for OC patients including cancer stem cells (CSC). MicroRNAs (miRNAs) are small, endogenous, and non-coding RNAs that play critical roles in the progression of various types of tumor. Our aim of this study was to find the regulatory function of microRNA-26 (miRNA-26b) on the cell proliferation and apoptosis of ovarian CSCs. Our studies show that miR-26b is under-regulated in human CD117+CD44+ ovarian CSCs. The miR-26b overexpression inhibits the cell proliferation and promotes cell apoptosis. Moreover, phosphatase and tensin homolog (PTEN) is found to be a functional target of miR-26b. Moreover, PTEN overexpression reversed the effects of miR-26b on the cell proliferation and apoptosis. PTEN overexpression remarkably accelerated the cell proliferation, and inhibited cell apoptosis. These results indicate that miR-26b regulates cell proliferation and apoptosis of CD117+CD44+ ovarian CSCs by targeting PTEN.>.

Abstract
Ovarian cancer (OC) is one of the most prevalent and deadly types of gynecological malignancy. Since current treatments are not effective against OC, it is imperative to develop novel potential therapeutic targets for managing OC. In this study, we aimed to uncover the underlying molecular mechanism of long non-coding RNA (lncRNA) GClnc1 related to p53 signaling pathway in OC. The expression of lncRNA H19 GClnc1 was markedly higher in OC samples than the related normal tissues. Next, we found that lncRNA GClnc1 inhibited p53. In addition, the lncRNA GClnc1 overexpression promoted the cell proliferation and migration in vitro. Subsequently, p53 silencing obligated the effect of lncRNA GCln1 knock down on cell proliferation and migration. To sum up, LncRNA GClnc1 contributes to the progression of OC by regulating p53 signaling pathway. Meanwhile, our findings also suggested that lncRNA GClnc1 may serve as a novel therapeutic target for OC patients.

Abstract
The purpose of our study was to investigate the inhibitory effect of carboplatin injection on human neuroblastoma human neuroblastoma cell (SK-N-SH) cells and to clarify its action mechanism. In this study, human neuroblastoma SK-N-SH cells were divided into two groups. The treatment group was intervened by carboplatin injection (25 μM), while the control group was intervened by drug solvent. After treating separately for 24 and 72 h, the cells were collected, and western blot (WB) and real-time PCR were used to detect the expression of the proliferation marker protein (Ki67); cells grown on cover slips were prepared and immunocytochemistry (ICC) and hematoxylin-eosin (HE) staining were adopted to observe the protein expression of Ki67 and the morphological changes of the cells; clone formation assay was used to detect the clonality of each cell group. The cytotoxicity of carboplatin on SK-N-SH cell was checked by AlamarBlue viability test. Both WB and PCR results showed that after cells were injected with carboplatin for 24 and 72 h, the expression levels of both Ki67 gene and protein were decreased, and they had a significant difference from those of the control group. Carboplatin injection inhibited the expression of Ki67, and the inhibitory effect was particularly significant as the action time prolonged. ICC results showed that the protein expression of Ki67 in the treatment group was lower than that in the control group, and there was a significant difference in expression between them. As shown by HE results, the number of cell necrosis and apoptosis in the treatment group was significantly higher than that in the control group, while the results of clone formation assay showed that in the treatment group, after being injected with carboplatin, the proliferation ability of cells was inhibited, so the number of cells was significantly reduced compared with that of the control group. Carboplatin at the tested concentration displayed no cytotoxicity on SK-N-SH cell. The conclusions are that carboplatin injection can inhibit human neuroblastoma SK-N-SH cells, and the longer it acts on SK-N-SH cells, the more obvious the inhibitory effect would be.

Abstract
Numerous studies have identified that microRNAs (miRs) play a crucial role in the tumorigenesis of non-small cell lung cancer (NSCLC). However, to the best of our knowledge, the physiological function of miR-103 in NSCLC is not fully understood. Experiments in the present study revealed that miR-103 expression was increased in NSCLC cell lines. In addition, a series of methods, including MTT, colony formation, 5-ethynyl-2′-deoxyuridine, Transwell, wound healing, flow cytometric, reverse transcription-quantitative PCR and western blot assays, were performed, which revealed that overexpression of miR-103 enhanced cell growth, migration, invasion and epithelial-mesenchymal transition (EMT), and suppressed apoptosis of A549 and H1299 cells. Additionally, a dual-luciferase reporter assay indicated that miR-103 directly targets the 3′-untranslated region of Kruppel-like factor 7 (KLF7), and KLF7 expression was negatively regulated by miR-103 expression. Furthermore, the present findings demonstrated that miR-103 promoted EMT via regulating the Wnt/β-catenin signaling pathway in NSCLC. Collectively, the current results demonstrated that miR-103 serves a tumorigenesis role in NSCLC development by targeting KLF7, at least partly via the Wnt/β-catenin signaling pathway. Consequently, these findings indicated that miR-103/KLF7/Wnt/β-catenin may provide a novel insight into underlying biomarkers for improving the diagnosis and treatment of NSCLC.

Abstract
Endometrial carcinoma (EC) is one of the most common gynecological cancers in many developing countries. Although tremendous advances have been made in the diagnosis and treatment of EC, there is still no adequate biomarker currently available for predicting the prognosis of this cancer. In this study, we found that miR-103 expression was significantly upregulated in EC tissues than their paired non-carcinoma tissues. Overexpression of miR-103 significantly promoted EC cell proliferation, while downregulation of miR-103 significantly suppressed EC cell proliferation. In addition, ZO-1 expression was significantly downregulated in the EC tissues than their paired non-carcinoma tissues. We also found an inverse correlation between ZO-1 and miR-103. Moreover, ZO-1 was validated as the direct target of miR-103. The downregulation of ZO-1 significantly enhanced EC cell proliferation. In conclusion, miR-103 could regulate EC cell proliferation through directly targeting ZO-1. Our results provide a potential development of microRNA-based targeted approaches for the treatment of EC.

Abstract
This study investigates the expression of phosphatase and tensin homolog (PTEN) and Inositol polyphosphate 4-phosphatase type II (INPP4B) in children with acute myeloid leukemia. The levels of PTEN and INPP4B in bone marrow, from 95 acute myelogenous leukemia (AML) patients and 84 controls, respectively, were assessed by immunohistochemistry, quantitative polymerase chain reaction (qPCR), and Western blot. The prognosis was followed up and investigated and the correlation analysis was made. We found that the expression levels of PTEN and INPP4B were significantly lower in the AML group than those in the control group ( P < 0.05). The survival time was lower in PTEN and INPP4B negative children relative to PTEN and INPP4B positive children ( P < 0.05). In AML patients, INPP4B and PTEN expression was positively correlated (r = 0.552, P = 0.000). In conclusion, the levels of INPP4B and PTEN were reduced significantly and correlated positively in AML patients accompanying with abnormal karyotypes. The current investigation of INPP4B and PTEN could give new insight into targeted therapy for AML.

Abstract
Estrogen evidently involves critically in the pathogenesis of gynaecological-cancers. Reports reveal that interference in estrogen-signalling can influence cell-cycle associated regulatory-processes in female reproductive-organs. The major determinants that influence E2-signallings are estrogen-receptor (ER), estrogen-sulfotransferase (SULT1E1), sulfatase (STS), and a formylglycine-generating-enzyme (FGE) which regulates STS activity. The purpose of this mini review was to critically analyze the correlation between oxidative-threats and redox-regulation in the process of estrogen signalling. It is extensively investigated and reported that oxidative-stress is linked to cancer. But no definite mechanism has been explored till date. The adverse effects of oxidative-threat/free-radicals (like genotoxic-effects, gene-regulation, and mitochondrial impairment) have been linked to several diseases like diabetes/cardiovascular-syndrome/stroke and cancer. However, a significant correlation between oxidative-stress and gynaecological-cancers are repeatedly reported without pointing a definite mechanism. For the first time in our study we have investigated the relationship between oxidative stress and the regulation of estrogen via estrogen metabolizing proteins. Reports reveal that ER, SULT1E1, STS and FGE are target-molecules of oxidative-stress and may function differently in oxidizing and reducing environment. In addition, estrogen itself can induce oxidative-stress. This fact necessitates identifying the critical connecting events between oxidative-stress and regulation of estrogen-associated-molecules (ER, SULT1E1, STS, and FGE) that favors tumorigenesis/carcinogenesis. The current review focus is on unique redox-regulation of estrogen and its regulatory-molecules via oxidative-stress. This mechanistic-layout may identify new therapeutic-targets and open further scopes to treat gynecological-cancers more effectively.

Li L, Ma L. Upregulation of miR-582-5p regulates cell proliferation and apoptosis by targeting AKT3 in human endometrial carcinoma. Saudi J Biol Sci 2018; 25:965-970. [PMID: 30108448 PMCID: PMC6088104 DOI: 10.1016/j.sjbs.2018.03.007] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2017] [Revised: 03/07/2018] [Accepted: 03/08/2018] [Indexed: 02/07/2023] Open
Abstract
The human endometrial carcinoma is one of the most common female malignancies, and there is an urgent requirement to explore new therapeutic strategies. There is accumulating evidence that microRNAs (miRNAs) can serve as potential diagnostic and prognostic biomarkers for various types of cancer, but the significance of miR-582-5p still remains largely unknown in the endometrial carcinoma. The aims of this study were to understand and identify the influence of miR-582-5p on the proliferation and apoptosis of human endometrial carcinoma and its relevant mechanism. First, quantitative real-time PCR (qRT-PCR) was used to detect miR-582-5p and AKT3 expression in human tissue samples and cells. Then, CyQuant assay and 2D colony assay were employed to evaluate cell proliferation. Western blotting was used to determine protein expression. Subsequently, the luciferase reporter assay was used to identify the target of miR-582-5p. Finally, Annexin V assay was used to detect cell apoptosis. We found that miR-582-5p expression was significantly decreased in human endometrial carcinoma tissues, and miR-582-5p upregulation in human endometrial carcinoma cells inhibit cell proliferation and promote apoptosis. Moreover, AKT3 was validated as a target of miR-582-5p and AKT3 expression was inversely correlated with miR-582-5p expression. Besides, AKT3 upregulation efficiently abrogates the effect of miR-582-5p on the cells. These results demonstrated that miR-582-5p regulates cell proliferation and apoptosis in human endometrial carcinoma via AKT3. Thus, miR-582-5p represents a potential therapeutic target in human endometrial carcinoma meriting further investigation.

[PMID: 30108432 PMCID: PMC6088105 DOI: 10.1016/j.sjbs.2017.09.015] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2017] [Revised: 09/28/2017] [Accepted: 09/30/2017] [Indexed: 02/07/2023] Open
Abstract
Small cell carcinoma of the prostate (SCCP) is a rare and the most aggressive variant of prostate cancer. There is no effective cure or treatment for SCCP. Therefore, there is an urgent need for new therapy to improve the prognosis of patients with SCCP. DUSP1 is a dual specific phosphatase with an increasingly recognized in tumor biology. Altered expression of DUSP1 induced changes in the expression of genes involved in various biological pathways, including cell-cell signaling and angiogenesis. To understand more about the role of DUSP1 in SCCP, we evaluated the biological function and associated regulatory mechanism of DUSP1. In this study, DUSP1 was significantly down-regulated in human SCCP compared with the non-carcinoma tissues (P < 0.05). Overexpression of DUSP1 was found to suppress MAPK signaling and cell proliferation in PC-3 cells. Additionally, silencing of DUSP1 enhanced MAPK signaling and PC-3 cell proliferation. Moreover, it was observed that DUSP1 blocked the phosphorylation of p38 MAPK induced by anisomycin. Taken together, this investigation suggests that DUSP1 is involved in the progression of SCCP and may provide a new therapeutic target for SCCP treatment.

Abstract
The present study aimed to evaluate the inhibitory effects of an irinotecan derivative, ZBH‑1208, on brain tumors, and to explore the underlying molecular mechanisms. To determine the effects of ZBH‑1208, a brain tumor mouse model was established by transplanting B22 cells. Subsequently, the visceral indices of immune organs and white blood cell counts were determined, and the effects of ZBH‑1208 on the expression levels of cell cycle‑related proteins were assessed by western blotting. The tumor inhibition rates of 20 and 40 mg/kg ZBH‑1208 were 11.7 and 54.1%, respectively. Compared with the negative control group, ZBH‑1208 barely affected visceral indices or white blood cell count. Furthermore, the expression levels of p53, p21, cyclin‑dependent kinase 7 (CDK7), Wee1, phosphorylated (p)‑cell division cycle 2 (CDC2) (Tyr15), p‑CDC2 (Thr161) and cyclin B1 proteins were upregulated, whereas the expression levels of cyclin E were downregulated, and those of CDC2, CDK2 and CDC25C were barely altered. In conclusion, the present study demonstrated that ZBH‑1208 suppressed the growth of B22 mouse brain tumor xenografts, but did not affect their visceral indices or white blood cell counts. It was suggested that ZBH‑1208 exerted its effects by regulating the expression of p53, p21, Wee1, p‑CDC2 (Tyr15) and cyclin E proteins.

Abstract
Objective: To evaluate the therapeutic effects of metformin and clomiphene in combination with lifestyle adjustment on infertility in women with obese polycystic ovarian syndrome (PCOS). Methods: A total of 101 infertile women with obese PCOS admitted to our hospital from July 2013 to July 2015 were randomly divided into an observation group (n=51) and a control group (n=50). The control group was treated with metformin plus clomiphene, based on which the observation group was also subjected to lifestyle adjustment. The body weight, body mass index (BMI) and waist-to-hip ratio (WHR) were measured before and after treatment. The changes of reproductive hormones, ovaries and endometrium were detected, and the rates of menstrual recovery, ovulation and pregnancy were observed. Results: The body weight and BMI of the observation group after treatment were significantly lower than those before treatment and of the control group (P<0.05). There was no significant difference in WHR between the two groups. In the observation group, there were significant differences in LH, T, LH/FSH, FINS and TG levels before and after treatment and from those of the control group after treatment (P<0.05). Both the left and right ovarian volumes of the observation group after treatment were significantly lower than those before treatment and of the control group after treatment (P<0.05). The menstrual recovery, ovulation and pregnancy rates of the observation group were significantly higher than those of the control group (P<0.05). Conclusion: Lifestyle adjustment combined with metformin and clomiphene can improve the reproductive endocrine and lipid metabolism of obese PCOS patients, decrease the volumes of left and right ovaries, and increase the menstrual recovery, ovulation and pregnancy rates.

Abstract
Objective: To explore the effects of letrozole (LE) in combination with low-dose intramuscular injection of human menopausal gonadotropin (HMG) on the ovulation induction and pregnancy of patients with polycystic ovary syndrome (PCOS). Methods: A total of 156 patients with PCOS infertility were randomly divided into an LE group, a clomiphene citrate (CC) group and an LE + HMG group (n= 52). LE and CC were orally taken according to the prescribed dosage on the 3rd-5th days of menstruation respectively, and 75 IU HMG was given through intramuscular injection. The ovulation induction parameters and pregnancy outcomes were observed. Results: The number of ovulation cycle of LE + HMG group was significantly higher than that of LE group (χ2=8.451, P<0.001). After injection of human chorionic gonadotropin, both endometrial thickness and number of mature follicles of LE + HMG group were significantly higher than those of other two groups (P<0.001), and the daily estradiol (E2) level was also higher (q=4.531, P<0.05). The pregnancy rate of LE + HMG group was 55.7%, which exceeded those of other two groups (compared to LE group, χ2=4.012, P<0.05). In LE + HMG group, the average medication cycle of clinically pregnant patients was (2.9 ± 0.3) weeks, which was significantly shorter than those of CC and LE groups (F=17.241, P<0.001). Conclusion: The regimen using LE in combination with low-dose intramuscular injection of HMG has satisfactory therapeutic effects on ovulation induction, short medication cycle and high clinical pregnancy rate, which is promising for treating patients with PCOS infertility.

Abstract
Objective: To evaluate the clinical therapeutic effects of mifepristone combined with gestrinone on patients with endometriosis. Methods: A total of 150 endometriotic patients treated in our hospital between January 2014 and December 2015 were randomly divided into a control group and a treatment group (n=75). The control group began to orally take gestrinone capsules on the second day after menstruation started (2.5 mg/time, twice/week). The treatment group orally took mifepristone tablets (12.5 mg/time, once/day), and the dosage and administration of gestrinone capsules were the same as those of the control group. After 24 weeks of consecutive treatment, the clinical therapeutic effects of the two groups were assessed, and the pelvic symptom score, clinical sign score, serum sex hormone levels and pregnancy outcomes were compared. Results: The total effective rates of control and treatment groups were 77.3% and 90.7% respectively, between which the difference was statistically significant (P<0.05). After treatment, the scores of pelvic symptoms (dysmenorrhea, dyspareunia, pelvic pain) and clinical signs (pelvic tenderness, induration) significantly reduced (P<0.05). Each score of the treatment group decreased more significantly than that of the control group did (P<0.05). The serum follicle hormone, luteinizing hormone, estrogen and progesterone levels were significantly lower than those before treatment (P<0.05). Each level of the treatment group dropped more significantly than that of the control group did (P<0.05). The pregnancy rates in the 6th and 12th months of follow-up were 28.0% and 13.3% in the control group respectively, and 42.7% and 29.3% in the treatment group respectively. Such rates of the two groups were significantly different at each follow-up time point (P<0.05). Conclusion: Mifepristone combined with gestrinone had satisfactory clinical therapeutic effects on endometriosis by reducing hormone levels and improving pregnancy outcomes. Therefore, this regimen is worthy of promotion and application in clinical practice.
