Exploring Tumor Macrophage Interaction in Anaplastic Thyroid Cancer
| Resumo: | "Anaplastic thyroid cancer (ATC) is the most aggressive form of thyroid cancer, with very high mortality rate. Tumor-associated macrophages (TAMs) can represent up to 70% of ATC’s tumor mass, making them an interesting target for novel therapies. In this thesis, the aim was to further understand the crosstalk between ATC and TAMs. To achieve that, cell surface proteomics of two ATC cell lines (C3948 and T235), in mono- or co-culture with THP-1-derived macrophage-like cells, was performed. The protein Spry-4, an inhibitor of the MAPK-ERK pathway, was found to be downregulated in C3948 cells upon co-culture. Spry-4 protein levels were further evaluated by Western blot; only T235 in co-culture showed a trend for downregulation, although without statistical significance.(...)" |
