Tailoring mathematical models to stem-cell derived cardiomyocyte lines can improve predictions of drug-induced changes to their electrophysiology (2017)
Journal Article

Human induced pluripotent stem cell derived cardiomyocytes (iPSC-CMs) have applications in disease modeling, cell therapy, drug screening and personalized medicine. Computational models can be used to interpret experimental findings in iPSC-CMs, prov...

Uncertainty quantification reveals the importance of data variability and experimental design considerations for in silico proarrhythmia risk assessment (2017)
Journal Article

The Comprehensive in vitro Proarrhythmia Assay (CiPA) is a global initiative intended to improve drug proarrhythmia risk assessment using a new paradigm of mechanistic assays. Under the CiPA paradigm, the relative risk of drug-induced Torsade de Poin...

Nonclinical cardiovascular safety of pitolisant: comparing International Conference on Harmonization S7B and Comprehensive in vitro Pro-arrhythmia Assay initiative studies (2017)
Journal Article

Background and purpose: We evaluated the concordance of results from two sets of nonclinical cardiovascular safety studies on pitolisant. Experimental approach: Nonclinical studies envisaged both in the ICH S7B guideline and Comprehensive in vitro P...

Early afterdepolarisation tendency as a simulated pro-arrhythmic risk indicator (2017)
Journal Article

Drug-induced Torsades de Pointes (TdP) arrhythmia is of major interest in predictive toxicology. Drugs which cause TdP block the hERG cardiac potassium channel. However, not all drugs that block hERG cause TdP. As such, further understanding of the m... Read More about Early afterdepolarisation tendency as a simulated pro-arrhythmic risk indicator.

Systems Toxicology: Real World Applications and Opportunities (2017)
Journal Article

Systems Toxicology aims to change the basis of how adverse biological effects of xenobiotics are characterized from empirical end points to describing modes of action as adverse outcome pathways and perturbed networks. Toward this aim, Systems Toxico... Read More about Systems Toxicology: Real World Applications and Opportunities.

Hierarchical Bayesian inference for ion channel screening dose-response data [version 2; peer review: 2 approved] (2017)
Journal Article

Dose-response (or 'concentration-effect') relationships commonly occur in biological and pharmacological systems and are well characterised by Hill curves. These curves are described by an equation with two parameters: the inhibitory concentration 50...

High resolution structural evidence suggests the Sarcoplasmic Reticulum forms microdomains with acidic stores (lysosomes) in the heart (2017)
Journal Article

Nicotinic Acid Adenine Dinucleotide Phosphate (NAADP) stimulates calcium release from acidic stores such as lysosomes and is a highly potent calcium-mobilising second messenger. NAADP plays an important role in calcium signalling in the heart under b...
