The Effect of Selenium Nanoparticles on the Osteogenic Differentiation of MC3T3-E1 Cells. NANOMATERIALS 2021; 11:nano11020557. [PMID: 33672352 PMCID: PMC7926403 DOI: 10.3390/nano11020557] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/16/2021] [Revised: 02/10/2021] [Accepted: 02/17/2021] [Indexed: 12/13/2022]
Abstract
Reactive oxygen species (ROS) regulate various functions of cells, including cell death, viability, and differentiation, and nanoparticles influence ROS depending on their size and shape. Selenium is known to regulate various physiological functions, such as cell differentiations and anti-inflammatory functions, and plays an important role in the regulation of ROS as an antioxidant. This study aims to investigate the effect of selenium nanoparticles (SeNPs) on the differentiation of osteogenic MC3T3-E1 cells. After fabrication of SeNPs with a size of 25.3 ± 2.6 nm, and confirmation of its oxidase-like activity, SeNPs were added to MC3T3-E1 cells with or without H2O2: 5~20 μg/mL SeNPs recovered cells damaged by 200 μM H2O2 via the intracellular ROS downregulating role of SeNPs, revealed by the ROS staining assay. The increase in osteogenic maturation with SeNPs was gradually investigated by expression of osteogenic genes at 3 and 7 days, Alkaline phosphatase activity staining at 14 days, and Alizarin red S staining at 28 days. Therefore, the role of SeNPs in regulating ROS and their therapeutic effects on the differentiation of MC3T3-E1 cells were determined, leading to possible applications for bone treatment.

Abstract
Selenium (Se) is an essential trace element that has several functions in cellular processes related to cancer prevention. While the cancericidal effect of Se has been reported in liver cancer, the mechanism has not been clarified. MiR-29a has widely been reported as a tumor suppressor; however, it also acts as a carcinogenic agent by increasing cell invasion in human epithelial cancer cells and hepatoma cells. In a previous study, we found that miR-29a-3p is a Se-sensitive miRNA. However, its effect in the chicken hepatocellular carcinoma cell line (LMH) is still unknown. In the present study, we found that the expression of miR-29a-3p in LMH cells was decreased by Se supplementation and increased under Se-deficient conditions. Flow cytometry and CCK-8 results suggested that Se decreased LMH cell proliferation induced by miR-29a-3p overexpression. Transwell and gap-closure assays implied that Se mediated LMH cell invasion and migration by downregulating miR-29a-3p. Quantitative real-time polymerase chain reaction and Western blotting results suggested that Se mitigated miR-29a-3p overexpression-induced LMH cell proliferation by downregulating CDK2, cyclin-D1, CDK6, and cyclin-E1. We further demonstrated that collagen type IV alpha 2 (COL4A2) is a target gene of miR-29a-3p. COL4A2 activates the RhoA/ROCK pathway to promote LMH cell invasion and migration. In conclusion, Se mediated miR-29a-3p overexpression induced LMH cell invasion and migration by targeting COL4A2 to inactivate the RhoA/ROCK pathway.

Abstract
Sphingolipids are a class of novel lipid bioregulatory molecules that play important roles in regulating cell growth, differentiation, proliferation, and apoptosis. Sphingolipid metabolism disorders could induce the development of various diseases including hepatocellular carcinoma (HCC). With the development of lipidomics, it has been demonstrated that sphingolipids play an increasingly essential role in the occurrence, development, and outcome of HCC. Studies have shown that sphingolipids can be used as a new biomarker for the diagnosis of HCC, and regulation of the sphingolipid metabolism pathway may be a potential target for the treatment of HCC. This paper reviews the current progress in research of sphingolipids with regard to their classification, metabolic pathways, role in the development of HCC, and the possibility as a target for diagnosis and treatment of HCC.

Abstract
Carcinogenesis is thought to be a multistep process, with clonal evolution playing a central role in the process. Clonal evolution involves the repeated 'selection and succession' of rare variant cells that acquire a growth advantage over the remaining cell population through the acquisition of 'driver mutations' enabling a selective advantage in a particular micro-environment. Clonal selection is the driving force behind tumorigenesis and possesses three basic requirements: (i) effective competitive proliferation of the variant clone when compared with its neighboring cells, (ii) acquisition of an indefinite capacity for self-renewal, and (iii) establishment of sufficiently high levels of genetic and epigenetic variability to permit the emergence of rare variants. However, several questions regarding the process of clonal evolution remain. Which cellular processes initiate carcinogenesis in the first place? To what extent are environmental carcinogens responsible for the initiation of clonal evolution? What are the roles of genotoxic and non-genotoxic carcinogens in carcinogenesis? What are the underlying mechanisms responsible for chemical carcinogen-induced cellular immortality? Here, we explore the possible mechanisms of cellular immortalization, the contribution of immortalization to tumorigenesis and the mechanisms by which chemical carcinogens may contribute to these processes.

Mitochondrial thioredoxin reductase inhibition, selenium status, and Nrf-2 activation are determinant factors modulating the toxicity of mercury compounds. Free Radic Biol Med 2014; 73:95-105. [PMID: 24816296 DOI: 10.1016/j.freeradbiomed.2014.04.030] [Citation(s) in RCA: 77] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/11/2014] [Revised: 04/21/2014] [Accepted: 04/27/2014] [Indexed: 01/21/2023]
Abstract
The thioredoxin system has essential functions in the maintenance of cellular redox homeostasis in the cytosol, nucleus, and mitochondria. Thioredoxin (Trx) and thioredoxin reductase (TrxR) are targets for mercury compounds in vitro and in vivo. This study aimed at understanding mechanistically how the mitochondrial and cytosolic thioredoxin systems were affected by mercurials, including the regulation of TrxR transcription. The effects of coexposure to selenite and mercurials on the thioredoxin system were also addressed. Results in HepG2 cells showed that TrxR1 expression was enhanced by Hg(2+), whereas exposure to MeHg decreased expression. Selenite exposure also increased the expression of TrxR1 and resulted in higher specific activity. Coexposure to 2 µM selenite and up to 5 µM Hg(2+) increased even further TrxR1 expression. This synergistic effect was not verified for MeHg, because TrxR1 expression and activity were reduced. Analysis of Nrf-2 translocation to the nucleus and TrxR mRNA suggests that induction of TrxR1 transcription was slower upon exposure to MeHg in comparison to Hg(2+). Subcellular fractions showed that MeHg affected the activity of the thioredoxin system equally in the mitochondria and cytosol, whereas Hg(2+) inhibited primarily the activity of TrxR2. The expression of TrxR2 was not upregulated by any treatment. These results show important differences between the mechanisms of toxicity of Hg(2+) and MeHg and stress the narrow range of selenite concentrations capable of antagonizing mercury toxicity. The results also highlight the relevance of the mitochondrial thioredoxin system (TrxR2 and Trx2) in the development of mercury toxicity.

Abstract
This study was performed to determine the hepatotoxicity of di(2-ethylhexyl)phthalate (DEHP) in relation to selenium status. In 3-week-old Sprague-Dawley rats, selenium deficiency was induced by a ≤0.05 selenium mg/kg. A selenium supplementation group was given 1 mg selenium/kg diet for 5 weeks. Di(2-ethylhexyl)phthalate-treated groups received 1000 mg/kg dose by gavage during the last 10 days of the experiment. Histopathology, peroxisome proliferation, catalase (CAT) immunoreactivity and activity and apoptosis were assessed. Activities of antioxidant selenoenzymes [glutathione peroxidase 1 (GPx1), glutathione peroxidase 4 (GPx4), thioredoxin reductase (TrxR1)], superoxide dismutase (SOD), and glutathione S-transferase (GST); aminotransferase, total glutathione (tGSH), and lipid peroxidation (LP) levels were measured. Di(2-ethylhexyl)phthalate caused cellular disorganization while necrosis and inflammatory cell infiltration were observed in Se-deficient DEHP group (DEHP/SeD). Catalase activity and immunoreactivity were increased in all DEHP-treated groups. Glutathione peroxidase 1 and GPx4 activities decreased significantly in DEHP and DEHP/SeD groups, while GST activities decreased in all DEHP-exposed groups. Thioredoxin reductase activity increased in DEHP and DEHP/SeS, while total SOD activities increased in all DEHP-treated groups. Lipid peroxidation levels increased significantly in SeD (26%), DEHP (38%) and DEHP/SeD (71%) groups. Selenium supplementation partially ameliorated DEHP-induced hepatotoxicity; while in DEHP/SeD group, drastic changes in hepatic histopathology and oxidative stress parameters were observed.
