The strengths and limitations of three nonclinical repolarization assays used to define the risk of clinical drug-induced delayed ventricular repolarization (a surrogate marker of the rare but potentially lethal arrhythmia Torsades de Pointes) were compared during a retrospective analysis of an anonymized database of 150 drugs submitted to the U.S. Food and Drug Administration (FDA) and characterized by a HESI Consortium.
The HESI Translational Biomarkers of Neurotoxicity Committee conducted a pilot study to identify noninvasive, fluidic biomarkers of neurotoxicity.
Proteins are fundamental to life and exhibit a wide diversity of activities, some of which are toxic. Therefore, assessing whether a specific protein is safe for consumption in foods and feeds is critical. Simple BLAST searches may reveal homology to a known toxin, when in fact the protein may pose no real danger.
