Research Interests
1. Physiology and Pharmacology of the Gastrointestinal Tract and Smooth Muscles: Potassium channels in the gastrointestinal tract and vascular smooth muscle (in vitro and in vivo models).
2. Cell-Based Biosensors, Pharmacology and Physiology, Drug Profiling, Disease Models (cardiac and neuronal hypoxia) in vitro: Electrophysiology, cell-integrated microelectrode arrays (MEAs) and field effect transistors in pharmacological and biomedical research, and disease model development.
3. Neuroscience and Cell Guidance: Micro-contact printing, neuronal cell patterning/organised formation of live neural network, synaptic formation, and neural toxicity.
4. Ophthalmology and Vision Research: Corticosteroids and other substances (e.g. Traditional Chinese Medicines) on retinal pigment epithelial cells, in vivo model of myopia, cell and molecular biology of the eye, cell transplantation, and toxicology of the eye.
Specific Projects
(1) Cardiac Pathophysiology
Two ischaemia models have already been established on the MEA for the study of the effects of KATP channels, especially mitoKATP and sarcKATP channels, on compromised cardiac functions and the significance of preconditioning. This research direction helps us to understand the processes involved in cardiac myocyte functions, and how we can alleviate the physiological changes that take place in ischaemia and hypoxia.
(2) Live Neural Network
The assembly of cultured mammalian neurons can help us unravel how neurons are organised, and whether the application of certain pharmacological agents could enhance synaptic formation. With this in mind, special chips that can ‘manipulate’ neurite outgrowth and synaptic formation (i.e. memory and strength of connectivity) have been designed and manufactured. Using the experience gained in cardiac ischaemia, I will also be examining ways to alleviate neuronal hypoxic damage.
(3) Gastrointestinal Motility
My PhD studies of how potassium channels affect GI motility involved the use of both in vitro and in vivo approach. Recently, I have again begun working on this important aspect of intestinal function using radiotelemetry, which provides very important physiological data such as wavefront propagation, as well as heart rate and body temperature that are often associated with emetic reflex.
(4) Immunopharmacology
I am the first to incorporate the use of MEA in the study of mast cell degranulation and histamine release (induced by compound 48/80, anti-IgE) and its relationship with potassium channel modulators (e.g. pinacidil, diazoxide, glibenclamide) and calcium channel blockers (e.g. verapamil and nifidepine). This research theme enables us to look into the control of immunological responses and how we can better control allergies such as asthma. We are currently in the process of applying an industrial grant for this line of research.
