Disease Focus: Toxicity

Understanding Chemotherapy-Induced Peripheral Neuropathy Mechanisms using CRISPRi and Chemical Screens in Human iPSC-Derived Sensory Neurons

Research Objective The research objectives are to identify causal genes for chemotherapy-induced mitochondrial toxicity and neurodegeneration in sensory neurons and drugs that target this toxicity. Impact These studies will open the possibility for genetic or drug targeting to prevent and treat drug-induced peripheral neuropathies and possibly neuropathies caused by disease or inherited. Major Proposed Activities […]

Human Cardiac Chip for Assessment of Proarrhythmic Risk

Research Objective This proposal will develop patient specific ‘heart-on-a-chip’ devices that will significantly impact early screening of drugs to accurately predict drug-induced proarrhythmia and toxicity. Impact Patient specific ‘heart-on-a-chip’ device will significantly reduce the cost of bringing a new drug candidate to market while improving efficacy. Major Proposed Activities To improve the maturity of human […]

Cell Villages and Clinical Trial in a Dish with Pooled iPSC-CMs for Drug Discovery

Translational Candidate Human stem cells in a dish engineered into heart cells to supplement, refine, reduce, and/or ultimately replace human clinical trials. Area of Impact Increase genetic diversity of preclinical studies in human samples to derisk clinical trials and save time and costs. Mechanism of Action We will have several non-invasive human-derived stem cells collected […]

A Novel, Robust and Comprehensive Predictive Tool Using Human Disease-Specific Induced Pluripotent Stem Cells for Preclinical Drug Screening

Translational Candidate A library of induced pluripotent stem cell-derived cardiomyocytes from healthy subjects as well as patients with common hereditary cardiac disorders Area of Impact Preclinical toxicity screening and drug discovery Mechanism of Action Patients with pre-existing cardiac conditions are more susceptible to drug-induced cardiotoxicity than general population. Including iPSCs derived from this subset of […]

Development of an hES Cell-Based Assay System for Hepatocyte Differentiation Studies and Predictive Toxicology Drug Screening

Drug-induced liver toxicity, including that from FDA-approved drugs, is the leading cause of liver failure in the US. One of the biggest road blocks to testing drug-induced liver toxicity prior to clinical studies or release of the drug into the market is the absence of a good model of human drug metabolism in the liver. […]

Induced Pluripotent Stem Cells for Cardiovascular Diagnostics

Our objective is to use induced pluripotent stem (iPS) cell technology to produce a cell-based test for long QT syndrome (LQTS), a major form of sudden cardiac death. Nearly 500,000 people in the US die of sudden cardiac death each year. LQTS can be triggered by drug exposure or stresses. Drug-induced LQTS is the single […]

Bruce Conklin Talks About Screening Drugs for Toxicity with Human Stem Cells

Jack Hubbard One possible use for pluripotent stem cells is to screen drugs for toxic side effects. The idea is that researchers could grow those stem cells into mature cell types such as heart, liver, or brains cells, expose them to new drugs or potential environmental hazards, then look for toxic side effects. Dr. Bruce […]
