Funding Amount
$605,190.00
Summary
The Hippo pathway is a key regulator of tissue growth. It was first discovered in vinegar flies and plays a similar role in mammals. We aim to define the mechanism by which the Tao kinase controls tissue growth by regulating the Hippo pathway. These studies will be performed in flies and mammalian cell culture. Our studies will shed light on how tissue growth is controlled, and have the potential to inform the way that we treat human cancers and tissue growth disorders.

Summary
The PI3K/AKT signalling pathway drives many cancers and until recently was thought to do so by preventing cancer cell death. We have shown this pathway also regulates the synthesis of ribosomes, the cellular “factories” that make protein and by interfering with PI3K/AKT regulated ribosome synthesis, can kill cancer cells. We aim to establish the mechanisms underlying this regulation of ribosome synthesis and to test the hypothesis that ribosome biogenesis is a novel target for cancer treatment.

Summary
Cells in our bodies are able to accomplish an impressive array of functions. Diffusible factors (called growth factors) are important in regulating diverse cellular functions. We have identified a new molecular switch inside cells that acts as a master controller of cellular functions. This molecular switch relays information to instruct specific cellular functions. We have shown that these molecular switches are short-circuited in breast cancer promoting cell growth and survival.
Biology Of EGFR Mutations In Glioblastoma Multiforme

Summary
The epidermal growth factor receptor (EGFR) is a protein that has a critical role in the development of normal cells. In glioma, the most lethal of the brain cancers, the EGFR is altered. These alterations result in uncontrolled activation of the EGFR, causing signals that promote the growth and survival of brain cancer. This grant seeks to understand the nature of the signals mediated by the altered EGFR, in turn helping us develop better therapeutics for the treatment of this deadly cancer.
Understanding The Role Of The IL11-Stat3-Th17 Signaling Axis In Gastrointestinal Cancer

Funding Amount

Summary
Gastrointestinal cancers arise when abnormal cells grow out from otherwise normal tissue. The resulting tumours contain a number of different types of cells, some of which help the tumour to grow, and some of which fight the tumour. We are interested in understanding how soluble molecules called cytokines influence the cells that promote tumour growth. In particular, we will explore the role of a cytokine called Interleukin-11 in these processes to identify novel cancer therapies.
Characterisation Of Two New Kinases In The Hippo Tumour Suppressor Pathway

Summary
The Hippo pathway is a key regulator of tissue growth. It was first discovered in vinegar flies and plays a similar role in mammals. We aim to define the mechanism by which the Gish and Fray kinases control tissue growth by regulating the Hippo pathway. These studies will be performed in flies and mammalian cell culture. Our studies will shed light on how tissue growth is controlled, and have the potential to inform the way that we treat human cancers and tissue growth disorders.

Identifying Novel Genome Instability Signatures In Cancer

Funding Amount
$320,891.00
Summary
Cancer is the single biggest clinical problem facing the world. An underlying hallmark of cancer is the accumulation of errors in the genetic information of a cell which arises through genomic instability. This research project aims to investigate novel molecules identified by our screening that function in response to genomic instability in cancer. This study is expected to define roles for each molecule in the maintenance of genomic stability and predict for patient diagnosis and outcome.
Investigating The Cellular Requirement For STIM1 Phosphorylation And Store-operated Calcium Entry Suppression During Mitosis: Roles In Development And Cancer
Funder
National Health and Medical Research Council
Funding Amount
$344,900.00
Summary
Cells are constantly interacting with and modifying their surrounding environment. The intracellular calcium signal is one mechanism cells use to translate signals from the microenvironment into cellular responses. This proposal seeks to explore why a key calcium signalling pathway, known as store-operated calcium entry, is specifically silenced during cell division, and to determine how reversing this inhibition affects cell division during normal development and in cancer.
Investigation Into The Roles Of Ena/VASP-Like And Protein Phosphatase 4C In DNA Damage Repair Via Homologous Recombination

Summary
The repair of DNA damage is a critical cellular mechanism that exists to ensure genomic stability. This project aims to investigate the role of the proteins Ena/VASP-Like and Protein Phosphatase 4C in DNA damage repair via homologous recombination. The DNA damage response pathway is an important area in the study of cancer and ageing, and the potential role of PP4C and EVL in homologous recombination needs to be investigated further.
