Temporal Profiling of PyMT Tumour Matrisome during Progression


ABSTRACT: In this study, through coupling of our ISDoT tissue decellularisation technology with quantitative mass spectrometry, we explored the changing tumour matrisome during mammary tumourigenesis in the PyMT breast cancer model compared to age-matched healthy control mammary gland

The tumour stroma, and in particular the extracellular matrix (ECM), is a salient feature of solid tumours that plays a crucial role in shaping their progression. Many desmoplastic tumours including breast cancer involve the significant accumulation of type I collagen. However, recently it has become clear that the precise distribution and organisation of matrix molecules such as collagen I is equally as important in the tumour as their abundance. Cancer-associated fibroblasts (CAFs) coexist wit  ...[more]
