Abstract
PURPOSE One of the most common causes of infertility in adult women is polycystic ovary syndrome (PCOS) which has been identified with symptoms such as chronic hyperandrogenism, anovulation, and polycystic ovaries. Adiponectin modulates steroidogenesis and the expression of ovulation-related genes. Herein, we assessed the effect of AdipoRon (adiponectin agonist) in the PCOS model mice. METHODS The PCOS model was induced with letrozole in the adult female mice and the animals received intraperitoneal injection of AdipoRon (5 mg/kg) for 10 days. Expression of CYP11A, CYP17A, and CYP19A genes, StAR protein, and histomorphology of the ovary were evaluated using real-time RT-PCR, western blotting, and histochemistry methods, respectively. RESULTS Although administration of letrozole caused an increase in the expression of CYP11A, CYP17A, and StAR and a decrease in the CYP19A1 expression, injection of AdipoRon reversed these changes. Moreover, AdipoRon treatment resulted in an improvement of folliculogenesis and a reduction of cysts compared to the letrozole-treated mice. CONCLUSION It is likely that AdipoRon has protective effects on the PCOS through modulation of cytochrome P450-related genes and steroidogenesis but needs further study to be sure.

Abstract
INTRODUCTION Endometrial thickness is an important parameter to evaluate endometrial receptivity. An appropriate endometrial thickness is necessary for both embryo implantation and maintaining normal pregnancy. Women with thin endometrium are one of the critical challenges in the clinic, and current therapeutic strategies for thin endometrium remain suboptimal. The stromal vascular fraction (SVF) derived from adipose tissue contains a variety of cells, mainly adipose-derived stem/stromal cells and adipose cells. Recently, adipose tissue-derived SVF showed tremendous potential for treating thin endometrium due to its capacity to repair and regenerate tissues. The application of SVF in animal models for treating thin endometrium has been investigated. However, limited evidence has demonstrated the efficacy and safety of autologous SVF in patients with thin endometrium. METHODS AND ANALYSIS This study is a single-centre, longitudinal, prospective self-control study to investigate the preliminary efficacy and safety of autologous SVF in improving the pregnancy outcome of infertile patients with thin endometrium. Thirty patients diagnosed with thin endometrium will be recruited based on the inclusion and exclusion criteria. The SVF suspension will be transferred into the uterine cavity via an embryo transfer catheter. Then, comparisons between pretreatment and post-treatment will be analysed, and the outcomes, including endometrial thickness, menstrual volume and duration, frequency and severity of adverse events and early pregnancy outcomes, will be measured within a 3-month follow-up, while late pregnancy outcomes and their offspring will be followed up via telephone for 2 years. The proportion of patients with improved symptoms will be calculated and compared. ETHICS AND DISSEMINATION This study was approved by the Ethics Committee of Peking University Third Hospital (reference number: REC2020-165). Written informed consent will be provided for patients before being included. The results will be presented at academic conferences and a peer-reviewed journal. TRIAL REGISTRATION NUMBER ChiCTR2000035126.

JOURNAL OF HAZARDOUS MATERIALS 2021; 412:125234.

Abstract
Silica nanoparticles (SiNPs) have drawn considerable attention due to their environmental health effects, while enhanced understanding of metabolic disorders has provided insight into related diseases. To investigate the impacts of SiNPs exposure on reproduction and reveal their pathogenic mechanisms, this study was designed and conducted from a metabolic perspective. First, fluorescein isothiocyanate (FITC)-SiNPs were chemically synthesized and applied to track SiNPs in vitro and in vivo. Next, 30 pregnant mice were intratracheally instilled with 1.25 mg of SiNPs/mouse, then sacrificed 24 h post-treatment. We found that SiNPs penetrated the trophoblast membrane, triggering apoptosis and inhibiting cell proliferation, invasion, and tube formation in a dose-dependent manner. Mechanistically, SiNPs dysregulated phosphofructokinase (Pfkl) and fructose-bisphosphatase 2 (Fbp2) and induced glucose depletion and pyruvate accumulation via the pentose phosphate pathway. Besides, the downregulation of caspase-3 suggested a causal relationship between pyruvate accumulation, pentose phosphate pathway activation, and cell apoptosis. Pfkl and Fbp2 was also dysregulated in vivo, and the uterine inflammation aggravated in a time-dependent manner. In conclusion, SiNPs triggered acute cytotoxicity and uterine inflammation by inducing glucose depletion and pyruvate overload in trophoblasts, which were mediated in part by Pfkl and Fbp2 via the pentose phosphate pathway.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2021; 762:143152.

Abstract
Exposure to silica nanoparticles (SiNPs) has been suggested to cause physical disorders, yet the effects of SiNPs on female reproduction have not been illustrated. This study was implemented to explore the reproductive toxicity of SiNPs on female and reveal its underlying mechanisms. Methodologically, the fluorescein isothiocyanate (FITC)-SiNPs were synthesized by coupling with FITC and then used to track the biodistribution of SiNPs in vitro and in vivo. In total, 30 mice were intratracheally injected 0.25 g of FITC-SiNPs, and 6 mice injected with the same volume of saline were used as controls. The results showed that SiNPs penetrated the cellular membrane, triggering apoptosis and inhibiting proliferation, tube formation, and invasion of trophoblast. Mechanistically, SiNPs was demonstrated to dysregulate Fbp2, Cpt1a, Scd1, and Pfkl, and further induced accumulation of pyruvate and fatty acid in mitochondria through the AMPK signaling pathway, which finally activated the Caspase-3-dependent apoptosis. Consistently, the similar alterations of these genes were detected in vivo, and the uterine inflammatory infiltration aggravated with the extension of the observation duration. These results suggested that SiNPs induced trophoblast apoptosis and uterine inflammation, and ultimately caused acute reproductive toxicity on female. The underlying mechanism might be explained by the dysregulation of Fbp2/Cpt1a/Pfkl/Scd1 axis, which promoted the overload of glucose and lipid through the AMPK signaling pathway. These findings were of great significance to guide a comprehensive understanding of the reproductive toxicity of SiNPs as well as the development of environmental standards.

Comparison of the regenerative effects of bone marrow/adipose-derived stem cells in the Asherman model following local or systemic administration. J Assist Reprod Genet 2020; 37:1861-1868. [PMID: 32535814 DOI: 10.1007/s10815-020-01856-w] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2020] [Accepted: 06/09/2020] [Indexed: 12/17/2022] Open
Abstract
PURPOSE Cell therapy is a promising strategy for the treatment of Asherman's syndrome (AS), but the origin of these cells and injection route influence the therapeutic effect and complications of cell therapy. Herein, we compared the effects of systemic or local intrauterine injection of bone marrow or adipose-derived mesenchymal stem cells (BMSCs/AMSCs) on the endometrium in a rat model of AS. METHODS After induction of AS in adult Wistar rats, the CM-Dil-positive BMSCs or AMSCs were injected either locally or intravenously. After 3 weeks, endometrial thickness, collagen deposition, cell migration, and VEGF expression were evaluated using histochemistry/immunofluorescence studies. RESULTS In all stem cell-treated groups, an ameliorative effect on the damaged endometrium was noted. Collagen deposition diminished in both groups (IV and local injection) compared to the AS model. In rats injected locally with MSC, fibrosis decreased compared to the other groups. Moreover, endometrial thickness increased in the groups that received local injection of BMSCs and AMSCs more than the IV-transplanted AMSCs group. Immunofluorescent staining demonstrated that although the systemic transplantation of BMSCs was more effective than the other groups on VEGF expression, it led to the lowest number of CM-Dil+ stem cells in the damaged endometrium. CONCLUSION Stem cell transplantation may reconstruct the damaged endometrium, but it is recommended to select the most effective stem cells and injection route. Because the removal of the fibrosis and the replacement of the epithelia cells is an effective therapeutic strategy for AS, in this study, we conclude that the local injection of AMSCs is more appropriate than BMSCs to treat AS.
