Summary
Metabotropic glutamate receptor 5 (mGlu5) is a major therapeutic target for depression and schizophrenia. The proposed studies will improve our understanding of how drug-like chemicals interact with mGlu5 and therefore change the activity of these receptors and in turn the activity of brain cells leading to therapeutic effectiveness. The research undertaken in this program will allow us to be smarter in developing new mGlu5 drugs that are both effective and have minimal side effects.
Understanding The Physiological Consequences Of Biased Signalling Mediated By The Glucagon-like Peptide-1 Receptor

Summary
The glucagon-like peptide 1 receptor is a major target for treatment of Type 2 diabetes and obesity. However, the development of drugs targeting this receptor is challenging as activation by different ligands can result in distinct signalling biases, a paradigm for which there is limited understanding of the physiological consequences. This project will address this critical knowledge gap and may allow for development of novel drugs with improved therapeutic outcomes.

Summary
We will investigate NDRG1, a novel molecular target that has been demonstrated to inhibit the progression of numerous cancers. We aim to better understand the underlying function of NDRG1 in pancreatic cancer and how we can potentially target this gene with novel therapeutics being developed in our lab. We hope that this new approach will lead to promising treatments and a better outcome for those suffering from pancreatic cancer.

Summary
Hearts respond to stimulation by activation of cell surface receptors. We have found that two very closely related receptors have opposing effects on the heart; one is beneficial and the other promotes disease. The planned studies will investigate exactly what explains this difference. This will identify critical factors that protect or damage the heart and is expected to provide suitable targets for drug development.
The Importance Of Receptor Trafficking For Signalling Of Pain And Inflammation

Summary
Inflammation and pain are normal processes that are essential for survival: inflammation fights infections and pain allows avoidance of danger. These processes are normally tightly controlled and are transient. During disease, they become dysregulated and chronic. By understanding the normal processes of inflammation and pain, and by determining how dysregulation causes disease, we aim to develop new treatments for diseases that are a major cause of human suffering.
Engendering Biased Signalling At The Human Calcium Sensing Receptor (CaSR) To Correct Pathophysiology

Funding Amount
$633,860.00
Summary
The human calcium sensing receptor (CaSR) has been targeted therapeutically in hyperparathyroidism and osteoporosis, but current CaSR therapeutics exhibit problematic side effects or are ineffective. Thus, the current research proposal seeks to understand the specific properties of CaSR drugs required to selectively control whole body calcium and bone mineral metabolism, to identify ligands that can mediate desired therapeutic effects at the exclusion of adverse effects.
Investigating The Impact Of Coincident Modulation Of Adenosine And Glutamate Receptors On Neuronal Activity – Implications For CNS Drug Discovery

Summary
Dementia in particular Alzheimer's disease, is one of the leading causes of death. There remains a need for new drugs to treat both symptoms and disease progression. Two receptors in the brain, the adenosine A1 (A1AR) and metabotropic glutamate 5 (mGlu5) are suggested to be promising new drug targets for dementia. In order to better develop drugs that target these receptors, we will develop a better understanding of activity of these receptors under conditions of health and disease.

Summary
G Protein-Coupled Receptors (GPCRs) form the largest family of receptors and drug targets in living organisms. Currently, the major reason that new drugs fail to reach the clinic is lack of appropriate drug effect (approx. 30%). Thus, we need a better understanding of how GPCRs work and how this relates to disease. Our Program addresses this knowledge gap, using GPCR models that are relevant to treatment of metabolic, inflammatory, cardiovascular and central nervous system disease.

Aurora Kinase: Molecular, Cellular And Functional Studies Deciphering Its Role In Stroke Injury

Funding Amount

Summary
In stroke patients, oxygen deprivation indirectly induces massive nerve cell death by activating an enzyme called aurora kinase A (AURKA). We aim at unravelling (i) how AURKA is activated by oxygen deprivation, (ii) where the activated AURKA is localised in cells, and (iii) how the activated AURKA induces nerve cell death.The study will benefit development of therapeutic strategies to protect against brain damage in stroke since this is novel and different target for drug targeting.
