Abstract
AIMS This study was to determine whether curcumin had any effect on the proliferation of neural stem cell (NSC), analyze the expression of glucocorticoid receptor (GR), signal transducer and activator of transcription 3 (STAT3), and Notch1 at transcription and protein level, and discuss the related mechanisms. METHODS AND RESULTS NSCs were harvested from E15 SD rat brain and cultured. All experiments were performed at the second passage. Cell cytotoxicity, cell viability, and proliferation assays were used to figure out the optimal concentration of curcumin, which can be used for the protein and mRNA studies. The results showed that by downregulation of GR and STAT3 expression, 0.5 μmol L-1 curcumin exhibited the most pronounced effect in promoting the proliferation of NSCs, which were also induced by antagonists of GR and STAT3, but was inhibited by GR agonist. CONCLUSION This study shows that low-dose curcumin stimulates the proliferation of NSCs, which is probably by inhibiting the mRNA and protein expressions of GR and directly or indirectly regulating the STAT3 via the synergistic effect of GR and STAT3 pathways and its related signal pathways.

DLEU1 contributes to ovarian carcinoma tumourigenesis and development by interacting with miR-490-3p and altering CDK1 expression. J Cell Mol Med 2017; 21:3055-3065.

Abstract
Recently, a large number of studies have focused on the important role of long non-coding RNAs (lncRNAs) in metabolism and development and have found that abnormal lncRNA expression is associated with the pathogenesis and development of many diseases. The lncRNA DLEU1 is involved in many solid tumours and haematological malignancies. However, its role in epithelial ovarian carcinoma (EOC) and the associated molecular mechanisms has not been reported. In this study, quantitative reverse transcription-PCR (qRT-PCR) demonstrated higher lncRNADLEU1 expression in EOC tissues than in normal tissues. Plasmid transfection of DLEU1 to up-regulate its expression in the ovarian cancer cell lines A2780 and OVCAR3 increased cell proliferation, migration, and invasion, while inhibited apoptosis. Nude mouse xenograft assay demonstrated that DLEU1 overexpression promoted tumour growth in vivo. QRT-PCR showed decreased miR-490-3p expression, while Western blotting demonstrated increased its target genes CDK1, cyclinD1 and SMARCD1, as well as matrix metalloproteinase-2 (MMP2), Bcl-xL and P70S6K protein expression, respectively. Short interfering RNA silencing of DLEU1 produced opposite results, where qRT-PCR showed increased miR-490-3p expression. The dual-luciferase reporter assay revealed a direct interaction between DLEU1 and miR-490-3p. MiR-490-3p plays a tumour suppressor role in epithelial ovarian cancer by targeting CDK1 regulation and influencing SMARCD1 and cyclin D1 (CCND1) expressions. Therefore, we suggest that through interaction with miR-490-3p, DLEU1 may influence the expression of CDK1, CCND1 and SMARCD1 protein, subsequently promoting the development and progression of EOC.

Abstract
MicroRNAs (miRNAs) are small non-coding RNAs that negatively regulate the translation of messenger RNAs by binding their 3′-untranslated region (3′ UTR). MiR-490-3p has been reported to be a suppressor in various human cancers; however, little is known about the biological functions of miR-490-3p in endometrial cancer (EC). In our study, we found that MiR-490-3p mRNA expression was significantly lower in ECs than in normal endometrial tissues. MiR-490-3p mRNA expression was also negatively associated with depth of invasion (mucosa vs. muscular and serosa) and lymph node metastasis (negative vs. positive) in EC. MiR-490-3p overexpression reduced proliferation; promoted G1 arrest and apoptosis; suppressed migration and invasion; and reduced TGFα, NF-kB, cyclin D1, survivin, matrix metalloproteinase 2 (MMP2) mRNA and protein expression, and improved Bax mRNA and protein expression. The dual-luciferase reporter assay indicated that miR-490-3p directly targeted TGFα by binding its 3′ untranslated region. MiR-490-3P transfection also suppressed tumor development and TGFα expression (as determined by immunohistochemistry and western blotting) in vivo in the xenograft mouse model. This is the first demonstration that miR-490-3P might act as a suppressor in EC tumorigenesis and progression by targeting TGFα. Our results provide a theoretical basis for the further study on the molecular target for endometrial cancer.

Abstract
AbstractEnvironmental pollution is a global problem; the lack of comprehensive toxicological assessments may lead to increased health risks. To fully understand the health effects of pollution, it is paramount to implement fast, efficient and specific toxicity screening that relies on human models rather than on time-consuming, expensive and often inaccurate tests involving live animals. Human stem cell toxicology represents a valid alternative to traditional toxicity assays because it takes advantage of the ability of stem cells to differentiate into multiple cell types and tissues of the human body. Thus, this branch of toxicology provides a possibility to assess cellular, embryonic, developmental, reproductive and functional toxicity in vitro within a single system highly relevant to human physiology. In this review, we describe the development, performance and future perspectives of stem cell toxicology, with an emphasis on how it can meet the increasing challenges posed by environmental pollution in the modern world.

Abstract
This study was undertaken to evaluate the possible role of several reproductive hormone receptors on the disruption of the hypothalamic-pituitary-testis (HPT) axis activity induced by perfluorooctane sulfonate (PFOS). The studied receptors are the gonadotropin-releasing hormone receptor (GnRHr), luteinizing hormone receptor (LHr), follicle-stimulating hormone receptor (FSHr), and the androgen receptor (Ar). Adult male rats were orally treated with 1.0; 3.0 and 6.0 mg of PFOS kg(-1) d(-1) for 28 days. In general terms, PFOS can modify the relative gene and protein expressions of these receptors in several tissues of the reproductive axis. At the testicular level, apart from the expected inhibition of both gene and protein expressions of FSHr and Ar, PFOS also stimulates the GnRHr protein and the LHr gene expression. The receptors of the main hormones involved in the HPT axis may have an important role in the disruption exerted by PFOS on this axis.

miR-98 and its host gene Huwe1 target Caspase-3 in Silica nanoparticles-treated male germ cells. Sci Rep 2015; 5:12938.

Abstract
Silica nanoparticles (NP) is one of the most commonly used nanomaterials with potential health hazards. However, the effects of Silica NP on germ cells and the underlying mechanisms are still unclear. In this study, GC-2 and TM-4, which are two different types of male germ cells were exposed to Silica NP for 24h, and then general cytotoxicity and multi-parameter cytotoxicity were evaluated. Our results showed that Silica NP could induce apoptosis in GC-2 cells. Transmission electron microscopy (TEM) results showed that Silica NP was localized in the lysosomes of GC-2 cells. High content screening (HCS) showed that Silica NP exposure could increased cell permeabilization and decreased mitochondrial membrane potential in GC-2 cells. The mRNA and protein levels of apoptosis markers (Bax, Caspase-3, Caspase-9) in GC-2 cells were significantly increased, while Bcl-2 was decreased. Accordingly, the expression level of miR-98, which can regulate Caspase-3, was significantly decreased. Huwe1, the host gene of miR-98, was positively associated with miR-98 expression after Silica NP exposure. Dual luciferase reporter assay suggested that miR-98 directly targets Caspase-3. These results suggest that Silica NP induces apoptosis via loss of mitochondrial membrane potential and Caspase-3 activation, while miR-98 plays key role in modulating this effect.

Abstract
The expression of microRNA-490-3P has been reported to regulate hepatocellular carcinoma cell proliferation, migration and invasion, and its overexpression significantly inhibits A549 lung cancer cell proliferation. Here, we demonstrated for the first time that miR-490 mRNA expression was significantly lower in ovarian carcinoma and borderline tumors compared to benign tumors, and lower in metastatic ovarian carcinoma (omentum) than primary ovarian carcinoma, and was negatively associated with differentiation and International Federation of Gynecology and Obstetrics (FIGO) staging. MiR-490-3P overexpression promoted G1/S or G2/M arrest and apoptosis; reduced cell proliferation, migration and invasion; reduced CDK1, Bcl-xL, MMP2/9, CCND1, SMARCD1 mRNA or protein expression; and induced P53 expression. Dual-luciferase reporter assay indicated miR-490-3P directly targeted CDK1. In vivo studies showed that miR-490-3P transfection suppressed tumor development and CDK1, Bcl-xL, MMP2/9 expression while inducing P53 expression. These findings indicate that miR-490-3P may target CDK1 and inhibit ovarian epithelial carcinoma tumorigenesis and progression.

Abstract
Gold nanorods (GNRs) are commonly used nanomaterials with potential harmful effects on male reproduction. However, the mechanism by which GNRs affect male reproduction remains largely undetermined. In this study, the metabolic changes in spermatocyte-derived cells GC-2 and Sertoli cell line TM-4 were analyzed after GNR treatment for 24 h. Metabolomic analysis revealed that glycine was highly decreased in TM-4 cells after GNR-10 nM treatment while there was no significant change in GC-2 cells. RT-PCR showed that the mRNA levels of glycine synthases in the mitochondrial pathway decreased after GNR treatment, while there was no significant difference in mRNA levels of glycine synthases in the cytoplasmic pathway. High content screening (HCS) showed that GNRs decreased membrane permeability and mitochondrial membrane potential of TM-4 cells, which was also confirmed by JC-1 staining. In addition, RT-PCR and Western blot indicated that the mRNA and protein levels of blood-testis barrier (BTB) factors (ZO-1, occludin, claudin-5, and connexin-43) in TM-4 cells were also disrupted by GNRs. After glycine was added into the medium, the GNR-induced harmful effects on mitochondria and BTB factors were recovered in TM-4 cells. Our results showed that even low doses of GNRs could induce significant toxic effects on mitochondria and BTB factors in TM-4 cells. Furthermore, we revealed that glycine was a potentially important metabolic intermediary for the changes of membrane permeability, mitochondrial membrane potential and BTB factors after GNR treatment in TM-4 cells.
