    Generation of Luciferase-expressing Tumor Cell Lines
    Authors:  Todd V. Brennan, Liwen Lin, Xiaopei Huang and Yiping Yang, date: 04/20/2018, view: 19, Q&A: 0
    Murine tumor models have been critical to advances in our knowledge of tumor physiology and for the development of effective tumor therapies. Essential to these studies is the ability to both track tumor development and quantify tumor burden in vivo ...
    3D Co-culture System of Tumor-associated Macrophages and Ovarian Cancer Cells
    Authors:  Lingli Long, Mingzhu Yin and Wang Min, date: 04/20/2018, view: 25, Q&A: 0
    Ovarian cancer is fairly unique in that ovarian carcinoma cells can detach and spread directly through peritoneal cavity. It has been unclear, however, how detached cancer cells survive in the peritoneum and form spheroid structure. We have recently ...
    FACS-based Glucose Uptake Assay of Mouse Embryonic Fibroblasts and Breast Cancer Cells Using 2-NBDG Probe
    Authors:  Shengli Dong and Suresh K Alahari, date: 04/20/2018, view: 22, Q&A: 0
    This is a flow cytometry-based protocol to measure glucose uptake of mouse embryonic fibroblasts (MEFs) and breast cancer cells in vitro. The method is a slightly modified and updated version as previously described (Dong et al., ...
    Generation of Luciferase-expressing Tumor Cell Lines
    Authors:  Todd V. Brennan, Liwen Lin, Xiaopei Huang and Yiping Yang, date: 04/20/2018, view: 19, Q&A: 0
    [Abstract] Murine tumor models have been critical to advances in our knowledge of tumor physiology and for the development of effective tumor therapies. Essential to these studies is the ability to both track tumor development and quantify tumor burden in vivo. For this purpose, the introduction of genes that confer tumors with bioluminescent ...
    3D Co-culture System of Tumor-associated Macrophages and Ovarian Cancer Cells
    Authors:  Lingli Long, Mingzhu Yin and Wang Min, date: 04/20/2018, view: 25, Q&A: 0
    [Abstract] Ovarian cancer is fairly unique in that ovarian carcinoma cells can detach and spread directly through peritoneal cavity. It has been unclear, however, how detached cancer cells survive in the peritoneum and form spheroid structure. We have recently reported that there is a strong correlation between Tumor-associated macrophages (TAMs)-associated ...
    FACS-based Glucose Uptake Assay of Mouse Embryonic Fibroblasts and Breast Cancer Cells Using 2-NBDG Probe
    Authors:  Shengli Dong and Suresh K Alahari, date: 04/20/2018, view: 22, Q&A: 0
    [Abstract] This is a flow cytometry-based protocol to measure glucose uptake of mouse embryonic fibroblasts (MEFs) and breast cancer cells in vitro. The method is a slightly modified and updated version as previously described (Dong et al., 2017). Briefly, the target cells are incubated with the fluorescently tagged ...
    Centromere Chromosome Orientation Fluorescent in situ Hybridization (Cen-CO-FISH) Detects Sister Chromatid Exchange at the Centromere in Human Cells
    Author:  Simona Giunta, date: 04/05/2018, view: 232, Q&A: 0
    [Abstract] Human centromeres are composed of large tandem arrays of repetitive alpha satellite DNA, which are often sites of aberrant rearrangement in cancers (Mitelman et al., 1997; Padilla-Nash et al., 2001). To date, annotation of the human centromere repetitive sequences remains incomplete, greatly hindering in-depth functional studies ...
    Primary Cultures from Human GH-secreting or Clinically Non-functioning Pituitary Adenomas
    Authors:  Roberto Würth, Alessandra Pattarozzi, Federica Barbieri and Tullio Florio, date: 04/05/2018, view: 138, Q&A: 0
    [Abstract] Pituitary adenomas are among the more frequent intracranial tumors usually treated with both surgical and pharmacological–based on somatostatin and dopamine agonists–approaches. Although mostly benign tumors, the occurrence of invasive behaviors is often detected resulting in poorer prognosis. The use of primary cultures from human pituitary ...
    Detection and Analysis of Circular RNAs by RT-PCR
    Authors:  Amaresh C Panda and Myriam Gorospe, date: 03/20/2018, view: 762, Q&A: 0
    [Abstract] Gene expression in eukaryotic cells is tightly regulated at the transcriptional and posttranscriptional levels. Posttranscriptional processes, including pre-mRNA splicing, mRNA export, mRNA turnover, and mRNA translation, are controlled by RNA-binding proteins (RBPs) and noncoding (nc)RNAs. The vast family of ncRNAs comprises diverse regulatory ...
    Quantitative Live-cell Reporter Assay for Noncanonical Wnt Activity
    Authors:  Edith P. Karuna, Michael W. Susman and Hsin-Yi Henry Ho, date: 03/20/2018, view: 412, Q&A: 0
    [Abstract] Noncanonical Wnt signaling functions independently of the β-catenin pathway to control diverse developmental processes, and dysfunction of the pathway contributes to a number of human pathological conditions, including birth defects and metastatic cancer. Progress in the field, however, has been hampered by the scarcity of functional assays for ...
    FACS-based Isolation of Neural and Glioma Stem Cell Populations from Fresh Human Tissues Utilizing EGF Ligand
    Authors:  Jessica Tome-Garcia, Fiona Doetsch and Nadejda M. Tsankova, date: 12/20/2017, view: 1147, Q&A: 0
    [Abstract] Direct isolation of human neural and glioma stem cells from fresh tissues permits their biological study without prior culture and may capture novel aspects of their molecular phenotype in their native state. Recently, we demonstrated the ability to prospectively isolate stem cell populations from fresh human germinal matrix and glioblastoma ...
    In vivo Leukemogenesis Model Using Retrovirus Transduction
    Authors:  Hiroshi Okuda and Akihiko Yokoyama, date: 12/05/2017, view: 738, Q&A: 0
    [Abstract] Various genetic alterations such as chromosomal translocation cause leukemia. For examples, gene rearrangements of the mixed-lineage leukemia (MLL) gene generate MLL fusion genes, whose products are potent oncogenic drivers in acute leukemia. To better understand the mechanism of disease onset, several murine leukemia models ...
    Myeloid Progenitor Transformation Assay
    Authors:  Hiroshi Okuda and Akihiko Yokoyama, date: 12/05/2017, view: 738, Q&A: 0
    [Abstract] Numerous oncogenes have been identified to cause leukemia. For example, chromosomal translocation generates various fusion genes of the mixed-lineage leukemia (MLL) gene and a partner gene in leukemia, whose gene products transform primary myeloid progenitors into an immortalized state. To characterize the transforming ability of leukemic ...
