  • NFKB1-miR-612-FAIM2 pathway regulates tumorigenesis in neurofibromatosis type 1
    on June 13, 2019 at 12:00 am

    Abstract Neurofibromatosis type I (NF1) is a carcinoma mainly featured by malignant peripheral nerve sheath tumor (MPNST). Dysregulated microRNAs (miRNAs) play decisive roles in tumor initiation and development. Our study sought for the possible roles of miR-612 in NF1. RT-qPCR estimated the expression of nuclear factor kappa B subunit 1 (NFKB1), miR-612, and Fas apoptotic inhibitory molecule 2 (FAIM2) in NF1, separately. Cell proliferation and migration were detected by CCK-8 and transwell experiments. Cell apoptosis was measured via flow cytometry and detection of the expression and activity of caspase 3/8/9. Luciferase reporter, ChIP, and RIP assays testified the interplay between studied genes. Rescue and in vivo assays affirmed the whole mechanism of miR-612 in NF1. We indicated that miR-612 was significantly low in tumor tissues and cells. Mechanism experiments confirmed that miR-612 promotion repressed cell proliferation and migration, and induced cell […]

  • Development and characterization of a stable bovine intestinal sub-epithelial myofibroblast cell line from ileum of a young calf
    on June 10, 2019 at 12:00 am

    Abstract Intestinal sub-epithelial myofibroblasts (ISEMFs) are mesenchymal cells that do not express cytokeratin but express α-smooth muscle actin and vimentin. Despite being cells with diverse functions, there is a paucity of knowledge about their origin and functions primarily due to the absence of a stable cell line. Although myofibroblast in vitro models for human, mouse, and pig are available, there is no ISEMF cell line available from young calves. We isolated and developed an ileal ISEMF cell line from a 2-d-old calf that expressed α-smooth muscle actin and vimentin but no cytokeratin indicating true myofibroblast cells. To overcome replicative senescence, we immortalized primary cells with SV40 large T antigen. We characterized and compared both primary and immortalized ileal ISEMF cells for surface glycan and Toll-like-receptor (TLR) expression by lectin-binding assay and real-time quantitative PCR (RT-qPCR) assay respectively. SV40 […]

  • LncRNA TUG1 contributes to cardiac hypertrophy via regulating miR-29b-3p
    on June 10, 2019 at 12:00 am

    Abstract Cardiac hypertrophy with maladjusted cardiac remodeling is the leading cause of heart failure. In the past decades, long non-coding RNAs (lncRNAs) and microRNAs (miRNAs) have been proved to exert multiple functions in cellular biological behaviors; however, their role in cardiac hypertrophy remains largely unclear. Presently, we first obtained hypertrophic H9c2 cells by treating with angiotensin II (Ang II) and uncovered upregulation of lncRNA taurine upregulated gene 1 (TUG1) in such H9c2 cells. Then, we demonstrated that silencing TUG1 attenuated Ang II–induced cardiac hypertrophy. Besides, a strong interactivity of TUG1 with miR-29b-3p at the putative sites was validated, suggesting that TUG1 was an endogenous sponge of miR-29b-3p in H9c2 cells. Additionally, the expression of miR-29b-3p was strikingly reduced by TUG1 upregulation and also inhibited under Ang II treatment, whereas it was restored after silencing TUG1 in hypertrophic cells. Also, we […]

  • A simple culture method for liver and intestinal tissue-resident macrophages from neonatal mice
    on June 1, 2019 at 12:00 am

    Abstract The liver and intestine contain a remarkably large portion of tissue-resident macrophage cells representing a phenotype that downregulates inflammation and initiates tissue repair. Here, liver and intestinal tissues obtained from neonatal mice were minced, enzymatically digested, and incubated in RPMI1640-based media. In a 2-wk culture, spherical floating cells emerged on a fibroblastic sheet. These cells showed phagocytic activity and F4/80+-CD11b+-CD206+-Arg1+-iNOS−-CD209a− phenotype, suggesting that these cells are tissue-resident macrophages. These macrophages proliferated in the co-culture system in the presence of fibroblastic feeder cell layer and absence of supplemental cytokines; the co-culture system did not cause a significant change in the phenotype of cells grown in a 4-wk culture. On the feeder cells, macrophage density was approximately 1.5 × 104/cm2 and the doubling time was approximately 70 h. Based on […]

  • Synthesis and biological evaluation of quercetin–zinc (II) complex for anti-cancer and anti-metastasis of human bladder cancer cells
    on June 1, 2019 at 12:00 am

    Abstract Bladder cancer is the 13th leading cause of cancer death worldwide, and its mortality rate is highly associated with the motility of the malignant cells. Although the techniques of urothelial cancer treatment have been continuously advanced in the last decade, the invasive bladder cancer remains incurable and the mean survival time of the patients with high-grade malignancy after cancer relapse is still < 6 months, indicating a new strategy which can reduce bladder cancer cell motility and/or progression is urgently needed. Quercetin is a polyphenolic flavonoid with approved anti-tumor effect. However, the drawbacks of quercetin, including low absorption, extensive metabolism, and rapid elimination, severely hamper its availability in the clinic. In this study, we aim to synthesize the quercetin–zinc complex (Q-ZnCPX) and explore its anti-cancer and anti-metastasis efficacies on human bladder cancer cells in vitro. Based on the results […]

  • BATF2 reverses multidrug resistance of human gastric cancer cells by suppressing Wnt/β-catenin signaling
    on June 1, 2019 at 12:00 am

    Abstract Gastric cancer (GC) is a commonly occurring neoplasm worldwide. The occurrence of multidrug resistance (MDR) in GC cells is the main obstacle to effective GC chemotherapy. The aim of the present study was to reveal the functional role and the underlying mechanisms of basic leucine zipper ATF-like transcription factor 2 (BATF2), a novel tumor suppressor, on MDR in GC cells. Here, we first found that SGC7901/VCR and SGC7901/ADR cells had higher drug resistance than SGC7901 cells using methylthiazol tetrazolium (MTT) and flow cytometry analysis. Moreover, MDR-related proteins and Wnt/β-catenin pathway markers were all upregulated in SGC7901/VCR cells compared to SGC7901 cells by quantitative reverse transcription-PCR (qRT-PCR) and western blot analyses. Subsequently, we observed BATF2 was downregulated in SGC7901/VCR cells and BATF2 overexpression significantly induced cell cycle G0/G1 phase arrest and apoptosis. Furthermore, overexpression of BATF2 […]

  • Targeted induction of bone marrow mesenchymal stem cells to have effectiveness on diabetic pancreatic restoration
    on June 1, 2019 at 12:00 am

    Abstract Although bone marrow-derived mesenchymal stem cells (BMSCs) have been reported to be effective for the attenuation of diabetes, they have limitations. Whether BMSCs can be target-induced by pancreatic stem cells (PSCs) to have effectiveness for the restoration of diabetic islet injury was unknown. In this study, based on their successful isolation and cultivation, BMSCs were co-cultured with PSCs. The pancreatic stem cells markers, Nestin and Neurogenin3 in co-cultured BMSCs were detected to evaluate the target-induction effects. After the diabetic rats were intravenously injected with the target-induced BMSCs, general indicators and islet morphology were detected. The islet insulin generation, and serum insulin and C-peptide contents were measured. It was found that after co-culture, the mRNA expressions, protein contents and distributions of Nestin and Neurogenin3, were dramatically high in BMSCs, indicating that they were successfully target-induced to […]

  • LIN28A-stabilized FBXL19-AS1 promotes breast cancer migration, invasion and EMT by regulating WDR66
    on June 1, 2019 at 12:00 am

    Abstract Breast cancer ranks as the top reason for the oncologic mortality for female around the world. The occurrence rate of breast cancer is rapidly rising, especially in China. Although the therapeutic regimes for breast cancer are diverse, the treatment outcome in patients remains dismal. Long non-coding RNAs have been greatly reported as important participators in cancer progression during the past decades. FBXL19 antisense RNA 1 (FBXL19-AS1) has been identified as a novel oncogene in colorectal cancer recently, but its role in breast cancer remains unknown. Present study attempted to explore the functional role and mechanism of FBXL19-AS1 in breast cancer progression. Expression of FBXL19-AS1, lin-28 homolog A (LIN28A), and WD repeat domain 66 (WDR66) were detected by qPCR and Western blotting. Transwell assay was used to detect cell migration and invasion. RIP assay was used to examine interaction between LIN28A and FBXL19-AS1. First, FBXL19-AS1 was highly […]

  • A simple method for the generation of insulin producing cells from bone marrow mesenchymal stem cells
    on June 1, 2019 at 12:00 am

    Abstract To produce insulin-producing cells (IPCs) from bone marrow mesenchymal stem cells (BM-MSCs) using a simple and cost effective method. During the initial 7 days of three-dimensional (3D) culture, BM-MSCs were cultured on 1% agar or agarose to form multicellular spheroids. Spheroids and spheroid-derived single cells (SS and SSC, respectively) were cultured in the absence of any proteinaceous growth factor in a simple specific medium for a further 7 d. The insulin content of the differentiated cells was evaluated at the mRNA and protein levels. Furthermore, the expression of pancreatic beta cells-related genes other than INS as well as the in vitro responses of IPCs to different glucose concentrations were investigated. Cellular clusters generated on agar and SS conditions (agar+SS-IPCs) stained better with beta cell specific stains and were more reactive to serum-containing insulin reactive antibodies compared with agarose-SS-IPCs. Gene expression […]
