Cellular & Molecular Metabolism

Research focus

Our research is focused on identifying genes, proteins and pathways that are important in metabolic disease and certain types of obesity related cancer, and then to develop pharmaceutical therapies that either activate or block the pathway of interest. We currently have several drug candidates that we are exploring.

Together with N-Gene Pharmaceuticals, we have developed a drug (BGP-15) that has anti-inflammatory and anti-fibrotic properties. BGP-15 is currently in Phase 2B clinical trials for the treatment of type 2 diabetes, but has also shown efficacy in pre-clinical experiments for the treatment of Duchenne Muscular Dystrophy, Heart Failure, and non-alcoholic steatohepatitis (NASH) principally due to its anti-fibrotic effects.

Almost a decade ago, work from our lab showed that cytokines from the gp130 family of cytokines (IL-6 and CNTF) can protect against obesity and insulin resistance by activation of the fuel sensing kinase, AMPK. With our collaborator Professor Stefan Rose John at the University of Kiel, this led to the development of IC7, a designer cytokine which is a chimera of CNTF and IL-6. IC7 is showing promise as a drug to treat obesity and type 2 diabetes and we have recently commenced pre-clinical development. We hope to start first in human trials within 24 months.

Finally, together with the University of Kiel, we recently showed that a drug that can block IL-6 “trans-signalling” (sgp130Fc) can markedly prevent inflammation. Phase 1 human clinical trials for sgp130Fc have recently been completed and we are now focusing on the role of sgp130Fc for the treatment of Rheumatoid Arthritis, NASH and other diseases where inflammation and fibrosis are major mediators.

Significant findings include:

  • Identification that muscle is an endocrine organ: IL-6 the first myokine
  • Identification that activation of HSP72 can result in protection against insulin resistance
  • Discovery that the mechanism of action of gp130 receptor ligands CNTF and IL-6 in protecting against obesity and insulin resistance is via the activation of skeletal muscle AMPK
  • The chemical chaperone BGP-15 can improve the pathology and functional capacity of skeletal muscle in muscular dystrophy and cardiac muscle in heart failure
  • Blocking IL-6 trans-signalling can prevent high fat diet-induced inflammation

Current laboratory groups and projects

The MUP-uPA mouse model of NASH mimics human disease (from Febbraio et al Cell Metabolism 2019).

Project 1  Obesity, NASH & liver cancer
(Project leader Dr Ebru Boslem)

Hepatocellular carcinoma (HCC) is one of the most fatal and fastest growing cancers. In recent years, non-alcoholic steatohepatitis (NASH) has been recognized as a major HCC catalyst. However, it is difficult to decipher the molecular mechanisms underlying the pathogenesis of NASH and understand how it progresses to HCC by studying humans. Consequently, progress in this field depends on the availability of reliable preclinical models that are amenable to genetic and functional analyses and exhibit robust NASH to HCC progression. Together with our collaborators at UCSD, we have developed a mouse model of NASH driven HCC that mimics human disease. We are uncovering novel pathways and therapies to treat this condition.

Project 2  Nexus between ceramides, metabolism and inflammation
(Project leader Dr Sarah Turpin-Nolan)

Ceramide accumulation represents a hallmark in the manifestation of numerous obesity-associated diseases such as type 2 diabetes mellitus and atherosclerosis. Until recently, ceramides were viewed as a homogenous class of sphingolipids. However, it has now become clear that ceramides exert fundamentally different effects depending on the specific fatty acyl-chain lengths that are integrated into ceramides by a group of enzymes known as (dihydro)ceramide synthases (CerS), as exemplified by distinct phenotypes of CerS-deficient mice. In addition, alterations of ceramide synthesis, trafficking and metabolism in specific cellular compartments exert distinct consequences on metabolic homeostasis. We are examining the emerging concept of how the intracellular location of acyl-chain length ceramides can regulate glucose metabolism, thus emphasising their targeting potential in the development of novel and specific therapies for obesity and obesity-associated diseases.

Project 3  Developing novel chimeric cytokine proteins for the treatment of metabolic disease (Project leader Prof Mark Febbraio)

IC7 is a novel chimeric cytokine that protects against metabolic disease.

Previous work from our laboratory demonstrated that the gp130 receptor cytokines interleukin-6 (IL-6) and ciliary neurotrophic factor (CNTF) can improve metabolic disease, but due to the known pro-inflammatory effects of IL-6 and the antigenic response to the clinically used form of CNTF (AxokineTM), both proteins were shown to have limited therapeutic utility for treatment of type 2 diabetes (T2D). Accordingly, we are engineering novel chimeric gp130 ligands to treat metabolic disease. We have shown that some of these new proteins significantly improve glucose tolerance and hyperglycemia and prevent weight gain and liver steatosis in both obese mice and in non-human primates. We hope to develop a realistic next-generation biological for the treatment of obesity, T2D, and age-associated sarcopenia, disorders that are currently pandemic.

Project 4  Development of novel drugs to treat age-related diseases
(Project leader Dr Peter Keov)

Together with N-Gene Pharmaceuticals, our group has been involved in the development of the small molecule named BGP-15, which is currently in two separate Phase 2 clinical trials for the treatment of type 2 diabetes (T2D) and idiopathic cardiomyopathy respectively. The drug has been shown to be extremely safe in five previous human intervention studies. We have demonstrated BGP-15 to be effective in treating a variety of pathologies including type 2 diabetes, muscular dystrophy, heart disease, and in the restoration of oocyte quality and embryo development. Our research indicates that BGP-15 is a promising drug for conditions in which mitochondrial function is impaired such as age-related sarcopenia. Mitochondrial function declines with age and is thought to contribute to many diseases associated with aging. Therefore, any therapeutic target that could improve the quality of life of aged Australians would have an enormous social and economic benefit for our country.

BGP-15 is antifibrotic and improves the pathology and lifespan of mice with muscular dystrophy (from Gehrig et al Nature 2012).

Project 5  Role of exercise and exosomes in age-related diseases
(Project leader Prof Mark Febbraio)

Small vesicles are released into the circulation with exercise, and participate in tissue cross-talk to prevent disease progression (from Whitham et al Cell Metabolism 2018).

Exercise represents a highly complex perturbation of homeostasis in a wide number of tissues, largely consequential of the increasing metabolic demands of contracting skeletal muscle. The integrated responses to these demands not only restore homeostasis in the short term, but when challenged regularly, produce adaptations associated with improved health and wellbeing. Indeed, poor exercise capacity is the most powerful predictor of mortality and there is evidence for the prescription of exercise as therapy for musculoskeletal, metabolic, cardiovascular, neurological and pulmonary diseases, as well as some cancers. Despite this, the mechanisms behind the therapeutic effects of exercise are not well understood and seem to go beyond simple management of energy balance and body weight. Over 15 years ago, we demonstrated that the pleiotropic cytokine interleukin-6 (IL-6) is released from skeletal muscle during exercise, resulting in the inception of the ‘myokine’ concept, that skeletal muscle functions as an endocrine organ. Inspired by the growing recognition that proteins can circulate packaged in extracellular vesicles (EV), we have taken the innovative approach of screening plasma taken from humans after exercise, focussing entirely on the EV fraction. We, therefore, have preliminary evidence describing an entirely novel mechanism by which tissue cross-talk occurs with exercise, that being via newly released exosomes. Accordingly, we have potentially uncovered an intriguing pathway by which exercise exerts its protective effects against many diseases including Alzheimer’s disease, liver disease and breast cancer.
