Mitochondrial donation in fertilised eggs is a possible therapy for avoiding mitochondrial DNA disease, but there are major safety concerns, such as mutant mitochondrial carryover. To address these concerns, we will develop two new methods to eliminate carryover risk, then translate our findings to human eggs. Also, we will determine if the mitochondrial donation procedure affects offspring health. Our findings will serve as a guide for adopting the technology.

Summary
Mitochondrial DNA (mtDNA) diseases are transmitted from a mother's eggs to her children. However, the levels of affected mtDNA differ amongst her eggs. Consequently, a carrier would not know if the newborn child were to suffer from these diseases. Mitochondrial Donation offers couples the potential to have an unaffected child. We will undertake the most comprehensive study of mitochondrial donation using one of its associated approaches to determine if it produces healthy embryos and offspring.
The Collagen-rich Matrix As A Driver Of Breast Cancer Progression And Resistance To Therapy

Summary
The extracellular matrix or 'matrix' surrounds all cells and is very important in controlling cell behaviour. In cancer, the matrix is dramatically altered, making cancer more aggressive. We recently developed a new way to study the matrix in breast cancer, and have analysed the matrix at different stages (Early/Mid/Late). We have uncovered exciting new matrix targets associated with more aggressive tumours. This project will validate their potential as therapeutic targets in breast cancer.
Harnessing Extracellular Matrix Remodelling By Cancer-Associated Fibroblasts To Increase T Cell Infiltration Of Solid Tumours

Summary
The ability of killer T cells to find and eliminate tumour cells is the basis for adoptive transfer immunotherapies, which thus far only work well with blood-borne cancers. There is limited success with solid tumours, which T cells do not readily infiltrate, notably because of remodelling by fibroblasts. We have discovered that T cells migrate in tunnels dug in the tumour matrix by fibroblasts. Here, we will harness this discovery to improve tumour infiltration and rejection of solid tumours.
Casting The Net: A New Approach To Identify Therapeutics To Treat Type-2 Diabetes

Summary
The discovery of treatments for type-2 diabetes (T2D) is a national health priority. In T2D, cells in the brain become 'insulin resistant' resulting in dangerously high blood sugar levels. There are no treatments for brain insulin resistance. The extracellular structures that surround brain cells undergo change in T2D, resulting in insulin resistance. By furthering understanding of these extracellular brain structures, this proposal will identify new drug targets to treat T2D.
