Cell Plasticity in Metastatic Colorectal Cancer

Project description

Unexplored aspects of the microenvironment in colorectal cancer

The tumour microenvironment (TME) is an integral part of tumours, with a central role in disease progression and prognosis. The TME consists of connective tissue and various non-malignant cells including fibroblasts, immune cells and mesenchymal stem cells. The EU-funded PLASTICAN project is interested to understand how the plasticity of stromal cells influences progression and metastasis in colorectal cancer. Researchers will study the mechanisms underlying the crosstalk between tumour and stromal cells and delineate the role of distinct cell types. Apart from fundamental knowledge in cancer biology, results have the potential to lead to novel therapeutic strategies for colorectal cancer.

Objective

Colorectal cancer (CRC) belongs to the most frequent tumor entities in both men and women. Although early detection and certain therapies have improved, the prognosis for patients with metastatic diseases is dismal and survival rates are below 10% at 5 years after diagnosis. Colorectal carcinogenesis is greatly dependent on the plasticity of both tumor cells as well as surrounding stromal cells within the tumor microenvironment. Among the latter, both T cells as well as mesenchymal cells substantially contribute to the survival prognosis. Importantly, mesenchymal cells are very heterogenous and various subtypes have been recently described in other tumor entities. Most likely these subtypes rather represent different activation states and have the capacity to interconvert, however, their precise functional role is unknown. Thus, a detailed mechanistic understanding about the cancer-stromal cross-talk as well as the stromal plasticity in CRC, particularly during late tumor stages and the relevance for metastasis development is lacking. Here we aim to perform well-defined hypothesis driven approaches to characterize the plasticity of both tumor and stromal cells and to develop innovative tools that will allow the functional analysis of distinct cell types in the stroma of primary tumors as well as in the pre-metastatic niche in the liver. This will be complemented by unbiased in vivo screens to identify novel pathways involved in plasticity of tumor epithelia and hepatocytes contributing to metastasis formation. Collectively, the combination of these comprehensive approaches that are based on sophisticated novel in vivo models as well as functional analysis of patient samples will ultimately aid the development of novel therapeutic strategies for late-stage CRC patients.

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Funding Scheme

Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.
