Electronic Thesis and Dissertation Repository
Transforming growth factor-β (TGFβ) signalling regulates growth, proliferation, immunity, and development. Although TGFβ typically antagonizes tumour formation, tumour cells often acquire mutations within the TGFβ signalling pathway that activate epithelial-mesenchymal transition (EMT). During EMT, epithelial tumour cells lose epithelial-like properties and acquire mesenchymal-like characteristics, which allows tumour cells to detach from the primary tumour and establish metastatic colonies. In addition to EMT, TGFβ augments tumourigenesis by increasing the degradation of damaged macromolecules and organelles via autophagy. Autophagy contributes to radiotherapy and chemotherapy resistance by mitigating the damages inflicted on tumour cells. Currently, there is a growing interest in the relationship …
