  • Macrophage plays important role in cortisol and serotonin induced adipogenesis in vitro
    on August 5, 2020 at 12:00 am

    Abstract Psychological stress is an important cause to induce various metabolic disorders such as obesity, type II diabetes, and cardiovascular disorders by affecting the visceral adipose tissue. Pathophysiology of these diseases is often accompanied by the hyperactive immune system. The hyperactive immune system causes immune cells to infiltrate in the adipose tissue to increase the severity of metabolic disorders and to affect the levels of stress associated hormones, such as cortisol and serotonin. Cortisol and serotonin, alone or together, could regulate several aspects of the metabolic and immunological deregulations by manipulating the lipid accumulation or adipogenesis in cells. During adipogenesis, macrophages are recruited. Previous reports from the Aich laboratory established the roles of cortisol and serotonin to influence adipogenesis in pre-adipocytes 3T3-L1 in the presence and absence of macrophages. In the current study, we reported the role of […]

  • Cyanidin improves oocyte maturation and the in vitro production of pig embryos
    on August 4, 2020 at 12:00 am

    Abstract The objective of this study was to reduce the negative effects of oxidative stress by decreasing the levels of reactive oxygen species (ROS) through supplementation of the major antioxidants present in elderberries: kuromanin and cyanidin. Oocytes (n = 1150) were supplemented with 100 or 200 μM of kuromanin or cyanidin during maturation, and then evaluated for ROS levels or fertilized and evaluated for penetration, polyspermic penetration, male pronucleus formation, and embryonic development. The ROS levels and incidence of polyspermic penetration were lower (P < 0.05) in oocytes supplemented with 100 μM cyanidin when compared with other treatments. Supplementation of 100 μM cyanidin increased (P < 0.05) MPN and blastocyst formation compared with other treatments. However, supplementation of 100 μM kuromanin did not have significant effects on the criteria evaluated, and […]

  • MiR-506-3p regulates autophagy and proliferation in post-burn skin fibroblasts through post-transcriptionally suppressing Beclin-1 expression
    on August 4, 2020 at 12:00 am

    Abstract MicroRNAs (miRNAs) is involved in diverse biological processes of cells including dermal fibroblasts that contributed to wound healing and resulted in keloid scarring. MiR-506-3p has been identified as a tumor suppressor or oncogene in fibroblasts of various cancers, while the role of miR-506-3p in regulating functions of post-burn dermal fibroblasts is poorly known. In this study, miR-506-3p was confirmed to be significantly downregulated in burned tissues and heat-stimulated dermal fibroblasts. Expression levels of autophagy-related proteins suggested thermal stimulus promoting the autophagy in dermal fibroblasts. Then, miR-506-3p inhibition enhanced cell proliferation and cell cycle process in dermal fibroblasts after thermal stimulus, whereas overexpression of miR-506-3p showed the opposite effect. Western blot assay showed that inhibition of miR-506-3p resulted in the upregulation of the expression levels of LC3-II, ATG5, and structural protein collagen […]

  • Bone marrow mesenchymal stem cell-derived exosomes attenuate cardiac hypertrophy and fibrosis in pressure overload induced remodeling
    on August 3, 2020 at 12:00 am

    Abstract The multiple therapeutic effects of bone marrow mesenchymal stem cells (BM-MSCs) have been verified in ischemic and reperfusion diseases. Exosomes are thought to play vital roles in MSCs-related cardioprotective effects. Recently, more and more evidences indicated that apoptosis and fibrosis were crucial pathological mechanisms in cardiac remodeling. Whether MSCs-derived exosomes could regulate cardiac hypertrophy and remodeling need to be explored. Murine BM-MSCs-derived exosomes were isolated by differential gradient centrifugation method. The transverse aortic constriction (TAC) mice model was established to promote cardiac remodeling. Cardiac function and remodeling were assessed via echocardiography and histology analysis. Myocytes apoptosis was determined by TUNEL fluorescence staining. Meanwhile, premature senescence was detected by β-galactosidase (SA-β-gal) staining. Related proteins and mRNA alternation were assessed via western blotting […]

  • Screening of single-cell clonal lines from Papilio demoleus Linnaeus cell lines for exogenous protein expression and adaptation in serum-free culture
    on July 31, 2020 at 12:00 am

    Abstract In this paper, four established cell lines derived from newly hatched larvae of Papilio demoleus Linnaeus and 57 single-cell clones derived from the 3 lines were used as test materials. Recombinant β-galactosidase baculovirus AcMNPV-Gal was used to infect the P. demoleus L. cell lines and the single-cell clones, and recombinant protein expression in each cell line was detected and compared. Three clonal cell lines, RIRI-PaDe-1-C1, RIRI-PaDe-2-C6 and RIRI-PaDe-3-C52, which showed significantly higher β-galactosidase expression levels than those of the parental cell lines, were selected. Five types of commercial serum-free media for insect cells, Express Five SFM, Ex-Cell 405, Sf-900III SFM, Sf-900II SFM and HyClone Serum-Free Media, were used to adapt RIRI-PaDe-2-C6 cells and RIRI-PaDe-3-C52 cells to serum-free culture conditions, and the growth characteristics of the cells and the exogenous protein expression characteristics before and after […]

  • MiR-34a suppresses osteoblast differentiation through glycolysis inhibition by targeting lactate dehydrogenase-A (LDHA)
    on July 27, 2020 at 12:00 am

    Abstract Bone formation (osteogenesis) is mediated through recruitment of bone marrow mesenchymal stem cells (MSCs) with capacity to differentiate into osteoblasts, a process which is regulated by transcriptional and post-transcriptional mechanisms. Multiple studies have suggested that miRNAs might have important roles in osteoblast differentiation. Expressions of miR-34a were detected by qRT-PCR. Cellular glucose metabolism was assessed by measurements of glucose uptake and lactate production. mRNA expressions of glycolysis enzymes were detected by qRT-PCR. Osteogenic differentiation of human MSCs (hMSCs) was analyzed by alkaline phosphatase (ALP) activity and Alizarin red staining. Here, we report that microRNA-34a is upregulated during the osteoblast differentiation from hMSCs. miR-34a overexpressing inhibited late osteoblast differentiation of hMSCs in vitro. The ALP activity and Alizarin red staining were significantly decreased by miR-34a in hMSCs. Target […]

  • Distinct differences in hypoxic responses between human oral mucosa and skin fibroblasts in a 3D collagen matrix
    on June 25, 2020 at 12:00 am

    Abstract The differences between oral mucosa and skin wound healing involving hypoxic responses of fibroblasts are poorly elucidated. In this study, we aimed to study the different hypoxic responses between oral and skin fibroblasts embedded in a three-dimensional (3D) collagen matrix to address the early stage of wound healing. Primary oral mucosa fibroblasts (OMFs) obtained from the retromolar area and skin fibroblasts (SFs) obtained from the abdomen were cultured in the 3D ‘floating model’ under either 21%, 5% or 1% O2 for 2 days. Cell viability under hypoxia was higher in the OMFs than in the SFs. Collagen gel contraction was suppressed under hypoxic conditions in both fibroblasts, consistent with the reduction of alpha smooth muscle actin expression, except for SFs under 1% O2. Subsequently, their gene expression profiles between 21 and 1% O2 concentrations were compared via microarray technology, and the expression profiles of the extracellular […]

  • Screening of integrins localized on the surface of human epidermal melanocytes
    on June 23, 2020 at 12:00 am

    Abstract In vivo, melanocytes occupy three-dimensional (3D) space. Nevertheless, most experiments involving melanocytes are performed in a two-dimensional microenvironment, resulting in difficulty obtaining accurate results. Therefore, it is necessary to construct an artificial in vivo–like 3D microenvironment. Here, as a step towards engineering a precisely defined acellular 3D microenvironment supporting the maintenance of human epidermal melanocytes (HEMs), we examined the types of integrin heterodimers that are expressed transcriptionally, translationally, and functionally in HEMs. Real-time PCR and fluorescent immunoassay analyses were used to elucidate the expression of integrin α and β subunit genes at the transcriptional and translational levels, respectively. The functionality of the presumed integrin heterodimers was confirmed using attachment and antibody-inhibition assays. Among the genes encoding 12 integrin subunits (α1, α2, […]
