The work described in this thesis aims to contribute to the knowledge on SUMO regulated oncogenesis, understanding the consequences of abolishment of SUMO signaling and exploiting the potential of SUMO E1 inhibitors. To this end, we describe SUMO as a potential biomarker for cancer aggressiveness and increase our understanding on SUMO’s role in cell cycle progression. We exploited the potential of SUMO E1 inhibition by combining with hypomethylating compound 5-Aza-2’ deoxycytidine, leading to increased cytostatic efficacy. Furthermore, we repurposed the SUMO E1 inhibitor TAK981 and hypomethylating drug 5-Aza-2’ deoxycytidine to improve engineered TCR (eTCR) T cell therapy and broaden our understanding of its immunomodulatory potential.
