Summary
Lymphatic vessels control tissue fluid drainage, inflammatory processes and cancer progression. We have used genetic approaches to discover an unexpected role for a family of factors (transcription factors) that regulate new lymphatic vessel formation. This project will investigate this biological function of these genes in detail in vascular formation. The project aims to generate important knowledge for vascular biology, vascular pathologies, cancer spread and future therapeutics.
Decoding The Transcriptional Program Of Vessel Growth In Health And Disease

Summary
Lymphatic vessels are essential to maintain fluid balance in most tissues of the human body. Further the lymphatic vasculature plays a central role during cancer and contributes to tumour metastasis. Despite this integral function in health and disease little is known about the molecular programs that coordinate gene expression to build a functional vasculature. This research project will address this gap in our knowledge and will open up new therapeutic avenues for lymphatic vascular disorders
Defining The Role Of GATA2 In Lymphatic Vascular Development As A Means To Understanding How GATA2 Mutations Predispose To Human Lymphedema.

Funding Amount

Summary
We have discovered that mutations in the transcription factor GATA2 result in human primary lymphedema, a debilitating disorder resulting from the failure of lymphatic vessels to return tissue fluid to the bloodstream. The goal of this application is to define the role of GATA2 in lymphatic vessels, in order to understand how GATA2 mutations cause lymphedema. Ultimately, we aim to identify targets to which desperately needed therapeutics for the treatment of lymphedema could be generated.
Characterisation Of A Newly Identified, Indispensible, Transcriptional Regulator Of Lymphangiogenesis

Summary
Lymphatic vessels form via lymphangiogenesis: growth of lymphatics from pre-existing vessels. This process is amenable to therapeutic intervention during metastasis because lymphatics support tumour spread. We discovered a gene that is essential for lymphangiogenesis to occur. We will investigate the control of lymphangiogenesis by this new factor. We aim to understand how it controls lymphatic vessel formation and identify genes within this pathway that have novel therapeutic potential.

Role Of Plzf – Sall4 Interactions In Germline Progenitor Function And Development

Summary
PLZF and SALL4 are critical stem cell factors and mutations in these genes are associated with developmental defects and cancer. SALL4 mutations are responsible for the malformation disease Duane-radial ray syndrome, while PLZF mutations lead to severe defects in the skeleton and gonads. We surprisingly found that PLZF and SALL4 interact and oppose each other’s functions. Our study of PLZF–SALL4 crosstalk will provide important insight into infertility, developmental disorders and cancer.
Lymphangiogenesis From Development To Disease: Analysis Of SOX18 Function In The Control Of Lymphatic Remodeling

Funding Amount

Summary
Cancers are lethal mainly because they spread (metastasise) to other parts of the body via blood vessels and lymphatic ducts. Pilot studies suggest that suppressing the function of a gene, SOX18, reduces tumour metastasis. We now propose to confirm these findings and study this effect in detail, with the ultimate aim of developing new therapies able to complement already existing anti-cancer treatments.
