    Imaging VIPER-labeled Cellular Proteins by Correlative Light and Electron Microscopy
    [Abstract] Advances in fluorescence microscopy (FM), electron microscopy (EM), and correlative light and EM (CLEM) offer unprecedented opportunities for studying diverse proteins and nanostructures involved in fundamental cell biology. It is now possible to visualize and quantify the spatial organization of cellular proteins and other macromolecules by FM, ...
    Implementing VIPER for Imaging Cellular Proteins by Fluorescence Microscopy
    Authors:  Julia K. Doh, Caroline A. Enns and Kimberly E. Beatty, date: 11/05/2019, view: 541, Q&A: 0
    [Abstract] Genetically-encoded tags are useful tools for multicolor and multi-scale cellular imaging. Versatile Interacting Peptide (VIP) tags, such as VIPER, are new genetically-encoded tags that can be used in various imaging applications. VIP tags consist of a coiled-coil heterodimer, with one peptide serving as the genetic tag and the other (“probe ...
    Generation of CoilR Probe Peptides for VIPER-labeling of Cellular Proteins
    Authors:  Julia K. Doh, Savannah J. Tobin and Kimberly E. Beatty, date: 11/05/2019, view: 587, Q&A: 0
    [Abstract] Versatile Interacting Peptide (VIP) tags are a new class of genetically-encoded tag designed for imaging cellular proteins by fluorescence and electron microscopy. In 2018, we reported the VIPER tag (Doh et al., 2018), which contains two elements: a genetically-encoded peptide tag (i.e., CoilE) and a probe peptide (i.e., ...
    Total RNA Isolation from Separately Established Monolayer and Hydrogel Cultures of Human Glioblastoma Cell Line
    Authors:  Manasi P Jogalekar and Elba E Serrano, date: 07/20/2019, view: 1332, Q&A: 0
    [Abstract] Astrocytoma is an invasive carcinoma occurring in the nervous system and currently lacks effective treatment options. A deeper understanding of the mechanisms of tumorigenesis and tumor progression is needed in order to develop novel therapeutic strategies. Recent advances in in vitro culture systems have demonstrated that the use of ...
    3D Co-culture System of Mouse Prostatic Wild-type Fibroblasts with Human Prostate Cancer Epithelial Cells
    Authors:  Veronica R. Placencio-Hickok, Manabu Kato and Neil A. Bhowmick, date: 05/05/2019, view: 1426, Q&A: 0
    [Abstract] Heterogeneous prostatic carcinoma-associated fibroblasts (CAF) contribute to tumor progression. This was established using transgenic mouse models. Paracrine interactions between fibroblasts and epithelial cells were further interrogated using isolated 2D cell culture systems, but 3D culture systems currently being developed can better mimic ...
    Unbiased Screening of Activated Receptor Tyrosine Kinases (RTKs) in Tumor Extracts Using a Mouse Phospho-RTK Array Kit
    Authors:  Julian Naipauer, Lucas E. Cavallin and Enrique A. Mesri, date: 04/20/2019, view: 1256, Q&A: 0
    [Abstract] Kaposi’s sarcoma (KS) herpesvirus (KSHV) is a virus that causes KS, an angiogenic AIDS-associated spindle-cell neoplasm, by activating host oncogenic signaling cascades through autocrine and paracrine mechanisms. Many host signaling cascades co-opted by KSHV including PI3K/AKT/mTORC, NFkB and Notch are critical for cell-specific mechanisms of ...
    Cluster Analysis of Endogenous HER2 and HER3 Receptors in SKBR3 Cells
    [Abstract] The Human Epidermal Growth Factor Receptor (HER) family of receptor tyrosine kinases consists of four, single pass, transmembrane receptor homologs (HER1-4) that act to regulate many critical processes in normal and tumor cells. HER2 is overexpressed in many tumors, and the deregulated proliferation of cancerous cells is driven by cooperation with ...
    In vitro NLK Kinase Assay
    Authors:  Sungho Moon, Jiyoung Kim and Eek‐hoon Jho, date: 11/05/2017, view: 5605, Q&A: 0
    [Abstract] This protocol provides step by step instructions to perform an in vitro kinase assay for nemo-like kinase. In addition, this protocol also describes an efficient method using mild lysis buffer for expression and purification of Glutathione S-transferase (GST) fusion proteins.
    High Fat Diet-induced Breast Cancer Model in Rat
    Authors:  Meng Ju Wu and Chun Ju Chang, date: 07/05/2016, view: 5270, Q&A: 0
    [Abstract] Obesity has been linked to breast cancer progression but the underlying mechanisms remain obscure. Being overweight or obese for a woman at the time she is diagnosed with breast cancer is linked to a high risk of recurrence regardless of treatment factors. In rodents, high body weight is also associated with increased incidence of spontaneous and ...
    Capturing the Driving Role of Tumor-host Crosstalk in a Dynamical Model of Tumor Growth
    Authors:  Sebastien Benzekry, Afshin Beheshti, Philip Hahnfeldt and Lynn Hlatky, date: 11/05/2015, view: 5901, Q&A: 0
    [Abstract] In 1999, Hahnfeldt et al. proposed a mathematical model for tumor growth as dictated by reciprocal communications between tumor and its associated vasculature, introducing the idea that a tumor is supported by a dynamic, rather than a static, carrying capacity. In this original paper, the carrying capacity was equated with the variable ...
