Research project objectives
The DC3 research project will focus on the evaluation of glycosyltransferases inhibitors and targeted approaches in gastrointestinal cancer models.
1) Analysis of the effects of the selected inhibitors in the glycan biosynthesis mediated by the targeted glycosyltransferases using glycoengineered cancer cell models.
2) Characterization and monitoring of the glycomic and glycoproteomic features induced by the inhibitors in advanced cancer models,
3) Evaluation of the functional biological effect of the glycosyltransferases inhibitors in cancer cells.
4) Analysis of the glycan-based therapeutic efficacy on the cancer models.
Instituto de Investigação e Inovação em Saúde (i3S)
The host laboratories (i3S) are equipped with modern equipment and facilities for analysis of the functional effects in the tumour biology and their potential therapeutic applications. Cell culture, molecular and genetic engineering, protein biochemistry, flow cytometry and FACS, confocal and electron microscopy, HPLCs, Mass (ESI/MS) spectrometers, proteomics, high-throughput screening and animal model facilities. Full access to the literature databases.
