Sickle Cell Disease was the first molecular disease described in man, and is the most prevalent. In some African countries, India and the Middle East, up to 20% of the population carry the sickle gene mutation. In developing countries, 90% of children die before 5 years of age. In developed countries, patients suffer a lifetime of chronic pain and die ~20 years early. We will employ new gene editing approaches to repair the mutation or recruit fetal hemoglobin to cure SCD in human samples.
Molecular Characterisation Of The DBHS Proteins In Telomerase Assembly

Summary
Telomerase is an enzyme that is active in over 90% of cancers. Telomerase activity allows cancer cells to divide an indefinite number of times. We have identified a novel role for the DBHS protein family in regulating telomerase activity. We aim to investigate the mechanisms by which these proteins function to assemble and transport telomerase to its site of action in the cell. We then aim to develop chemical inhibitors of these proteins, and test their utility in preventing cancer cell growth.
Targeting PD-1 Expressing T-peripheral Helper (Tph) Cells And Dysregulated Checkpoint Molecules: Improving Outcomes In Rheumatoid Arthritis

Summary
Rheumatoid arthritis is a chronic disease, causing pain, swelling and irreversible deformity of the joints. We propose to investigate the immune cell environment that drives this disease. In particular, we will focus on a new type of cell called Tph cells and related immune pathways. We will also study how they may be used as therapeutic targets or as markers to monitor disease activity. Our findings may translate into clinical practice and form a basis for new therapeutic strategies.

Summary
Genetic information underpins all life on earth and is processed to make proteins, which determine the characteristics of an organism. However, only about 2% of our whole genome is made up of genes that encode proteins; the other 98% is non-coding and its function remains poorly understood. This proposal aims to utilize cutting edge genomic technologies to generate new knowledge about how the non-coding genome regulates the expression of protein coding genes in human autoimmune disease.
About one in eight known genetic disorders involve DNA alteration that activates a cellular quality control mechanism that disables the affected gene. This mechanism is more efficient in some individuals than others. It can influence disease outcomes and severity. We will engineer and apply tools and models to measure and manipulate this crucial cellular mechanism. This will allow us to predict disease severity as well as to intervene where a manipulation of this mechanism will be beneficial.
Discovering The Cell Of Origin For Rare Ovarian Cancers

Funding Amount
$599,438.00
Summary
Ovarian cancer has many different varieties, and even though they all grow at the ovary, for some types we don't know the cell where the cancer starts. Using novel sequencing methods, this study will find the tissue of origin for two rare subtypes. This finding will help us to develop appropriate pre-clinical models that we can use to test emerging cancer therapies. Identifying the cell of origin will provide key insights into early detection or even prevention of these rare but deadly diseases.
Exploiting Messenger RNA Export As A Novel Therapeutic Strategy To Treat Cancer

Summary
Novel therapies for cancers represent an area of unmet clinical need. We have identified a new biological pathway implicated in cancer, namely selective mRNA export. Compounds inhibiting other steps of the gene expression pathway are promising therapeutic candidates for cancer, yet mRNA export inhibitors do not exist. We propose to develop first-in-class inhibitors of mRNA export that selectively target transcriptionally addicted cancers with dysregulated RNA processing.
Reprogramming Human Fibroblasts Into Induced Trophoblast Stem Cells

Funding Amount

Summary
We have been able to generate artificial human trophectoderm which is the tissue that creates the placenta. This will allow us to do research in how the genes control the fate of these cells without the need of human embryos or placenta. We anticipate that the derivation and characterising these cells will revolutionise placenta research, which in turn will contribute to the establishment of new therapies for placenta disease and infertility.
Hybrid Optical-electrical Stimulation For Precise Neural Stimulation

Summary
In world-first research, we have evidence that combining electrical stimulation with optical stimulation significantly and safely improves precision of neural activation for devices such as cochlear and retinal implants. In this proposal we will use gene therapy to make nerves responsive to light in pre-clinical animal models to establish proof of concept that hybrid stimulation will significantly improve outcomes for recipients of cochlear and retinal implants.
Repeat Expansions In Neurological Disease: Discovery, Interpretation And Enhanced Diagnostics

Summary
Identifying the mutation or genetic cause of disease in an individual is the first step in the provision of appropriate clinical care and treatment. This diagnostic process is being revolutionised through the ability to sequence the entire human genome in a time and cost effective manner. This project will enable identification of novel and known repeat expansion using whole genome sequencing, providing rapid diagnoses and better clinical care for individuals with neurogenetic disorders.
