Accelerating virtual patient generation with a Bayesian optimization and machine learning surrogate model

open access: yesCPT: Pharmacometrics &Systems Pharmacology, Volume 14, Issue 3, Page 486-494, March 2025.
Abstract The pharmaceutical industry has increasingly adopted model‐informed drug discovery and development (MID3) to enhance productivity in drug discovery and development. Quantitative systems pharmacology (QSP), which integrates drug action mechanisms and disease complexities to predict clinical endpoints and biomarkers is central to MID3.

Neuronal reprograming of protein homeostasis by calcium-dependent regulation of the heat shock response. [PDF]

open access: yesPLoS Genetics, 2013
Protein quality control requires constant surveillance to prevent misfolding, aggregation, and loss of cellular function. There is increasing evidence in metazoans that communication between cells has an important role to ensure organismal health and to ...

Pathogenic CaV1.1 Variants Cause Hyperpolarizing Shift of Depolarization-Induced Ca2+ Release in Malignant Hyperthermia Susceptibility

open access: yesCommunications Biology
Malignant hyperthermia (MH) is a potentially fatal genetic disorder triggered by certain anesthetics, leading to excessive calcium release in skeletal muscle. While most MH-associated mutations affect the type 1 ryanodine receptor, a Ca2+ release channel

Disturbances in Calcium Homeostasis Promotes Skeletal Muscle Atrophy: Lessons From Ventilator-Induced Diaphragm Wasting

open access: yesFrontiers in Physiology, 2020
Mechanical ventilation (MV) is often a life-saving intervention for patients in respiratory failure. Unfortunately, a common and undesired consequence of prolonged MV is the development of diaphragmatic atrophy and contractile dysfunction.

The Ryanodine Receptor/Calcium Release Channel and its Interaction Partners

open access: yesMicroscopy and Microanalysis, 1998
Abstract Ryanodine receptors (RyRs) function as the major intracellular calcium release channels in striated muscle, where they also play a central role in excitation-contraction (e-c) coupling, the signal transduction process by which neuron-induced depolarization of the muscle plasma membrane leads to release of Ca from the ...

Compartmentalisation in cAMP signalling: A phase separation perspective

open access: yesBritish Journal of Pharmacology, EarlyView.
Cells rely on precise spatiotemporal control of signalling pathways to ensure functional specificity. The compartmentalisation of cyclic AMP (cAMP) and protein kinase A (PKA) signalling enables distinct cellular responses within a crowded cytoplasmic space.

Mice null for calsequestrin 1 exhibit deficits in functional performance and sarcoplasmic reticulum calcium handling. [PDF]

open access: yesPLoS ONE, 2011
In skeletal muscle, the release of calcium (Ca(2+)) by ryanodine sensitive sarcoplasmic reticulum (SR) Ca(2+) release channels (i.e., ryanodine receptors; RyR1s) is the primary determinant of contractile filament activation.

Inhibition of late sodium current prevents pathological hyperactivation of calcium/calmodulin‐dependent protein kinase IIδ in a murine model of acute doxorubicin‐related cardiotoxicity

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Doxorubicin (DOX) is a highly effective anthracycline, whose clinical application for cancer is limited by cardiotoxicity. The mechanisms underlying doxorubicin‐induced toxic cardiomyopathy (DICM) involve electrophysiological remodelling with intracellular Na+ overload because of increased late INa and hyperactivation of

Voltage sensing mechanism in skeletal muscle excitation-contraction coupling: coming of age or midlife crisis?

open access: yesSkeletal Muscle, 2018
The process by which muscle fiber electrical depolarization is linked to activation of muscle contraction is known as excitation-contraction coupling (ECC).
