About the Project

Osteosarcoma (OS) is the most common bone malignancy that predominately affects children and adolescents, with a secondary peak of incidence in older adulthood. Patients with non-metastatic disease have a 5-year survival rate of close to 70%; however, those with metastatic disease have a 5-year survival rate as low as 19%. Metastasis is a big clinical problem as 15-20% of OS patients present with metastases at diagnosis and 40% will eventually develop metastases. The membrane protein leucine-rich repeat containing 15 (LRRC15) is a novel type I membrane protein, which displays a restricted expression pattern in normal tissue but is highly expressed in many solid tumours. It is highly expressed on the cell surface of both the tumour cells and stromal fibroblasts in mesenchymal-derived tumours, including OS, where there is a potential association between high LRRC15 expression and poor prognosis. There is a particular need for targeted or novel agents that can be used to prevent and/or treat metastatic disease.    

Aims / Approach:

This project aims to investigate the role of LRRC15 in OS. Firstly, we will determine whether LRRC15 is required for migration and invasion of OS cells by manipulating LRRC15 levels and performing migration and invasion assays, that will include standard endpoint transwell assays, as well as more advanced microfluidic-based 3D cell culture chips with chemically defined hydrogels at around 1250Pa stiffness. Such a functional assay assesses directional cell movement in real-time using fluorescently labelled cells and offers significant advantages over the traditional assay. Secondly, we will determine the signalling changes downstream of LRRC15 in OS cells using cutting-edge third generation mRNA sequencing and bioinformatics. Thirdly, we will characterize expression of LRRC15 in FFPE OS samples with linked clinical outcome.
