Automation of a Novel Cell-Based ELISA for Cell Signaling Pathway Analysis
Wendy Goodrich, Peter Banks, Ron Osmond, Antony Sheehan

Monitoring and quantifying cell signaling pathways is critical for understanding the behavior of cell processes and many disease states. Monitoring and quantifying cell signaling pathways is critical for understanding the behavior of cell processes and many disease states.

Improving Cell-Mediated Cytotoxicity Assessment through the Use of an Automated Luminescent ADCC Assay
Brad Larson, Sumant Dhawan, Shalini Wadwani, and Peter Banks

Assays that can assess the ability of a biosimilar to act in a manner similar to the original biologic have seen increased interest. This poster describes the use of a non-radioactive luminescent chemistry to simplify the assay process and provide improved data quality.

Antigen Determination in Autoimmune Hepatitis Type1
Naveen L Gupta, S Nayak, S Shakeyavar

Objectives of this project were to exploit the database in indian setting to determine nuclear antigens as target for antinuclear antibodies (ANA) in patients of autoimmune hapatitis (AIH) type1.

High Content Analysis of Neural Stem Cell Expansion and Differentiation
Oksana Sirenko, Allan C. Powe, Steven L. Stice, Karen Cook, Nick Callamaras, Jayne Hesley, Xin Jiang and Evan F. Cromwell

Automated assay methods for monitoring neural stem cell expansion and differentiation using stem cell derived neural cell lines and high content imaging systems have been described.

Global Gene Expression Changes Induced In Primary Human Hepatocytes By Thiazolidinediones Upon Repeat Dosing of HepatoPac™ Cultures
Michael McVay and Salman R. Khetani

An assessment of global gene expression changes in HepatoPac, a micropatterned co-culture of hepatocytes and stromal cells.

High-Throughput Campaign to Identify Reversible Small Molecule Inhibitors of p97
Kelin Li, Tsui-Fen Chou, Kevin Frankowski, Brian E. Nordinc, Patrick Porubsky, Mathew P. Patricellic, Han-Jie Zhou, Sam Gerritz, Raymond J. Deshaies, Jeffrey Aubé, Frank J. Schoenen*

The AAA ATPase p97 is a critical factor in maintaining protein homeostasis in eukaryotic cells. Two probe compounds ML240 and ML241 were developed that both inhibit p97 ATPase activity with an IC50 of approximately 100 nM, and block degradation of p97-dependent proteasome substrate with an IC50 of approximately 900 nM and 3500 nM, respectively. They specifically targeted p97, exhibited markedly different potencies for activating executioner caspases and blocking cell growth.

Using the Promega GloSensor™ cAMP technology on the FLIPR® Tetra system for live cell Gi- and Gs- coupled GPCR second messenger assays
J. Pschorr, S. Lydford, C. Crittenden and Y.-W. Chen

Detection of Gs- and Gi-coupled GPCR second messenger signal activity has been traditionally accomplished using endpoint assays such as radioactive binding or cAMP assays that require cell lysis. This poster demonstrates the use of the modified luminescent firefly luciferase-based Promega GloSensor™ cAMP Assay on the FLIPR® Tetra system to enable detection of cAMP mediated Gs- and Gi-coupled GPCR activity in a true kinetic assay.

Neurotoxicity Assays Using iPSC-Derived Neurons and High Content Imaging
Oksana Sirenko, Susan DeLaura, Lucas Chase, Jayne Hesley and Evan F. Cromwell

Neurotoxicity can cause temporary or permanent damage of brain or peripheral nervous system and has been found to be a major cause of neurodegenerative diseases such as Alzheimer’s or Parkinson’s. Accordingly, there is a great interest in developing more predictive, disease relevant cell-based models and efficient screening tools for assessing the neurotoxicity of chemical compounds, drug candidates and environmental agents.

SpectraMax® Microplate Readers: A complete solution for Transcreener® assays
Cathleen Salono, Caroline Cardonnel, Kasia Proctor and Cathy Olsen

Transcreener® ADP2 Assays are homogenous assays with fluorescent readouts that enable the detection and screening of established drug targets including protein and lipid kinases, as well as emerging targets such as carbohydrate kinases, triphosphatases, heat shock proteins and other ATPases.

Research led by scientists at The University of Texas Health Science Center at Houston (UTHealth) has revealed a new electrical mechanism that can control these switches.
Signature of Microbiomes Linked to Schizophrenia
Studying microbiomes in throat may help identify causes and treatments of brain disorder.
Inflammation Linked to Colon Cancer Metastasis
A new Arizona State University research study led by Biodesign Institute executive director Raymond DuBois has identified for the first time the details of how inflammation triggers colon cancer cells to spread to other organs, or metastasize.
Structural Discoveries Could Aid in Better Drug Design
Scientists have uncovered the structural details of how some proteins interact to turn two different signals into a single integrated output.
Determining the Age of Fingerprints
Watch the imprint of a tire track in soft mud, and it will slowly blur, the ridges of the pattern gradually flowing into the valleys. Researchers have tested the theory that a similar effect could be used to give forensic scientists a way to date fingerprints.
Genetic Overlapping in Multiple Autoimmune Diseases May Suggest Common Therapies
CHOP genomics expert leads analysis of genetic architecture, with eye on repurposing existing drugs.
Surprising Mechanism Behind Antibiotic-Resistant Bacteria Uncovered
Now, scientists at TSRI have discovered that the important human pathogen Staphylococcus aureus, develops resistance to this drug by “switching on” a previously uncharacterized set of genes.
Tissue Bank Pays Dividends for Brain Cancer Research
Checking what’s in the bank – the Brisbane Breast Bank, that is – has paid dividends for UQ cancer researchers.
Researchers Publish Landmark “Basket Study”
Researchers from Memorial Sloan Kettering Cancer Center (MSK) have announced results from the first published basket study, a new form of clinical trial design that explores responses to drugs based on the specific mutations in patients’ tumors rather than where their cancer originated.
