Antibody-based Inhibition Of ADAM10 As Cancer Immunotherapy

Funding Amount
$652,788.00
Summary
Despite our advances in understanding the molecular basis of cancer, treatments for metastatic cancers are limited, emphasising an urgent need for strategies targeting several oncogenic pathways. We generated monoclonal antibodies effectively blocking the activity of ADAM10, an oncogenic cell surface protease that activates tumour growth, invasion and metastasis through multiple pathways. Here we describe the strategies that progress these antibodies as lead therapeutics for clinical testing.
EphA3 Is A Marker Of Glioma Stem/progenitor Cells And A Potential Target For Therapy.

Summary
EphA3 is a cell surface marker which is enriched on glioma ‘propagating’ stem cells (GSCs) and furthermore has a functional role in regulating GSC differentiation and fate determination. EphA3 therefore provides a novel therapeutic target for high-grade glioma.
Novel Dual Domain Targeting Strategies Against ErbB Receptors

Funding Amount
$711,216.00
Summary
This project will develop innovative strategies to treat cancer through novel antibodies to erbB growth factor receptors, and identify ways to improve conventional treatments.
This Fellowship will focus on the development of novel therapeutics for cancer, and identify mechanisms for selection of treatments best suited to individual patients. It will also develop innovative strategies to identify cancer through molecular imaging techniques.
ADAM Metalloprotease Inhibition For Treatment Of Colorectal Cancer

Summary
Colorectal cancer (CRC) causes over 4000 deaths/year, typically from developing drug resistance and spreading to other organs (metastasis). These processes involve tumour cells called cancer stem cells (CSCs), which rely on specific cell surface proteins for survival and function. We are developing antibodies against one of these type of proteins, to test in mouse models of CRC. These already show promise in targeting CSCs and inhibiting drug-resistance and metastasis in mice.
Inhibiting Tumour Growth By Targeting EphA3 And Disrupting Tumour Stromal And Vascular Microenvironment

Funding Amount
$645,136.00
Summary
Tumours consist of cancer cells, tumour blood vessels and connective tissue, all of which are different to normal tissues. Many of the cells making up tumour vessels and connective tissue are recruited, during initial growth and subsequent spreading of tumours, from the bone marrow. Our research will examine the presence and function of the EphA3 receptor on these cells during tumour development and assess how our anti-EphA3 antibody inhibits tumour growth by targeting stroma and vasculature.
Therapeutic Targeting Of MYCN Oncoprotein Stability In Neuroblastoma

Funding Amount
$590,206.00
Summary
A high level of MYCN protein is a major indicator of aggressive neuroblastoma (NB) but unfortunately there have been many barriers to the design of targeted therapies. We have identified a protein called PA2G4 which is a cofactor for MYCN in promoting cancer cell growth. We have developed a compound which inhibits PA2G4 and MYCN protein levels and reduces tumour growth. We will examine how PA2G4 cause aggressive tumour characteristics and test new methods to block PA2G4.
The critical role of the class III histone deacetylase SIRT2 in stabilizing N-Myc oncoprotein. Cancer is the commonest cause of death from disease in children. Neuroblastoma is the commonest solid tumor in early childhood. This project will investigate the critical roles of SIRT2 protein in increasing the expression of N-Myc oncoprotein and consequently inducing neuroblastoma, and SIRT2 inhibitors as anticancer agents.
Mitochondrially targeted anti-cancer drugs modulate the mitochondrial genome. Successful cancer management requires novel therapeutical approaches. This project will test the effect of a new class of compounds that target mitochondria, the powerhouse of the cells, where they suppress expression of mitochondrial genes. By this mechanism, cancers that are resistant to apoptosis induction can be inhibited.
Towards Better Treatments For Acral Melanoma Through Functional Genomics

Summary
Acral melanoma is an uncommon melanoma subtype with bad prognosis that has been poorly characterised at the molecular level. The project will conduct comprehensive analysis of acral melanoma at the DNA, RNA and protein levels. Through subsequent functional follow-up studies of key drivers of this cancer type we will identify novel drug targets to treat this disease.
