Cancer at the cellular level, Cancer Research at Otago

Cancer biology, Department of Pathology

Cancer is a cell growth disease where cells undergo division many more times than normal. This makes the cells prone to replication errors—mistakes that occur during the copying of the DNA on the chromosomes that occurs in each cell division. If these mistakes or mutations are not repaired they accumulate. As more and more mutations accumulate they affect cell processes involving death, location, intercellular communication and others. Eventually these rogue cells become cancers.

The Department of Pathology, Dunedin School of Medicine, has a number of laboratories that work on different aspects of cancer biology.

Centre for Translational Cancer Research - Te Aho Matatū

Translational cancer research bridges the gap between laboratory-based science and treatment in the clinic. We now have sufficient knowledge in the fields of cancer biology, molecular biology, and immunology to make a significant impact on the treatment and management of cancer.

We're bringing about rapid improvements in cancer outcomes by addressing defined clinical problems. Our research is accelerating the development and testing of new drugs and diagnostic tools that directly assist clinicians and their patients.

Our research programmes include:

Clinical Genetics Group

Our group identified mutations in a gene called WTX as the cause of osteopathia striata congenita with cranial sclerosis (OSCS). This is an X-linked dominant disorder characterized by the accrual of dense, sclerotic bone throughout the skeleton, most especially the skull. Males who are hemizygous for a disease-causing mutation are severely affected—not only with skeletal manifestations, but also with malformations in multiple organ systems, which are often life-limiting.

Several surprising aspects have arisen out of this discovery. For instance, WTX is a negative regulator of WNT signaling and it has also been shown to be a tumour suppressor gene, implicated in the development of Wilms tumour, a kidney cancer which primarily affects children. Ongoing work in the laboratory is aimed at disentangling this developmental disease-cancer link in addition to addressing questions around how defects in WNT signaling can cause such widespread malformations in several organ systems.

Mackenzie Cancer Research Group

We are interested in the pathology of human tumours and in identifying the genetic changes that give rise to cancer. Our research focuses on the molecular regulation of tumour growth, metastasis and response to therapy.

Due to our close links with clinicians at Christchurch hospital and with the Cancer Society Tissue Bank, together with our laboratory expertise, we are able to carry out investigations that span from bench to bedside.

Microbiology and Immunology

The Department of Microbiology and Immunology has a large number of research programmes across the fields of microbiology, immunology and virology.

Cures for infectious and autoimmune diseases, as well as non-communicable diseases such as cancer and asthma, require knowledge of the immune response and how it can be manipulated.

Professor Alex McLellan is studying the immune response to cancer, specifically the roles of T cells, NK(natural killer) cells and extracellular vesicles in antigen presentation.

Professor Ros Kemp is looking at T cell and myeloid cell subsets in colorectal cancer and inflammatory bowel disease to improve diagnosis, prognosis and treatment.

Oral molecular and immunopathology

Our programme, at the Sir John Walsh Research Institute, aims to investigate the cellular, and molecular basis of oral diseases, and their treatment.

Oral mucosal diseases including oral squamous cell carcinoma are being investigated using single and double layer immunofluorescence and immunohistochemistry coupled with focused micro-arrays to determine gene expression profiles. Of major interest is regulation of the local immune response in oral mucosal lichen planus and in oral squamous cell carcinoma.

Angiogenesis, and endoplasmic reticulum stress are also being investigated in these lesions so as to develop a better understanding of the role of these mechanisms in the pathogenesis of mucosal lesions.

Pharmacology and Toxicology

In the Department of Pharmacology and Toxicology state-of-the-art technologies, including the use of in vivo disease models, are used to undertake integrative, cellular and molecular investigations aimed at understanding animal and human pathophysiology (and to delineate targets for novel drugs).

Dr Sarah Baird's group is interested in how the supportive area surrounding the cancer cells, the stroma, develops and functions. The lab also specializes in determining cell death mechanisms.

Professor John Ashton's group is currently investigating mechanisms of drug resistance to small molecule inhibitors in oncogene-dominant non-small cell lung cancer, and ALK positive lung cancer in particular. They also have an interest in modelling disease for drug testing, and are currently working on developing cancer spheroids for drug screening. In addition, his group is actively investigating the mechanism of action of the Sea-sponge derivative spiroleucettadine and the pharmacokinetics of camptothecin derivatives.

Many cancers are challenging to treat as they cannot be targeted by cytotoxics, and additionally they can acquire resistance to known cellular poisons. To solve this problem the Giles Group investigates redox active agents, a drug class that selectively destroys tumours based upon their redox status. The Group's work ranges from drug design through to the in depth pharmacological analysis of the mechanism-of-action of new therapeutics.

Protein biochemistry, structural biology and apoptosis

Many key events within cells are regulated by the appropriate interaction of two proteins. Understanding the molecular basis of protein-protein interactions is central to elucidation of these cellular processes and can lead to the development of new or improved therapeutic compounds.

Professor Catherine Day is interested in understanding how a number of proteins involved in apoptosis interact, and how this knowledge can be exploited for the development of improved anti-cancer compounds. Most recently, her group has focused on characterisation of processes that result in attachment of ubiquitin to proteins because the addition of ubiquitin regulates protein interactions and protein abundance—both of which regulate signalling pathways.

Structural biology of cellular signalling

Professor Peter Mace's lab aims to understand signalling networks that regulate how cells respond to stress or proliferative stimuli. Of particular interest are the mechanisms by which phosphorylation, ubiquitination and proteolysis act to control fundamental cellular processes such as proliferation and cell death.

Using a combination of structural biology, biochemistry and cell-based we aim to decipher how signalling proteins regulate these outcomes in normal cells, how signalling is disrupted in cancer, and how this understanding can be translated into more effective disease therapy.

Current projects in the lab include understanding stress-activated MAP kinase activation, and how ubiquitin regulates transcriptional networks in differentiating and cancerous states.
