About the Project
We have identified tensin as a crucial regulator of the trafficking of cell adhesion receptors of the integrin family, which promotes ECM endocytosis. We hypothesise that the adhesion protein tensin 3 (TNS3) is a key mediator of the transition from DCIS to IDC, through the regulation of ECM dynamics. This is particularly important considering the fact that 20-50% of DCIS lesions progress to IDC, but to date reliable indicators of invasive progression are missing 5. Importantly, despite the clear indication that ECM remodelling accompanies DCIS to IDC transition, the underlying molecular mechanisms have not been investigated 5. The findings of this study will significantly progress our understanding of breast cancer progression, guiding and contributing to the development of the field of cell-ECM adhesion.
Using advanced imaging techniques and 3D cell culture systems, this project will:
- Characterise the role of TNS3 in controlling ECM uptake and breast cancer cell invasive migration
- Elucidate how TNS3 controls ECM organisation and invasive carcinoma progression
- Define whether TNS3 expression correlates with breast cancer progression in humans
The outcomes of this project will determine whether targeting TNS3-dependent integrin trafficking may represent a novel strategy to limit invasive breast cancer.
