Dr. Sendoel has had a long-term interest in the principles underlying tumor formation and cancer progression.  Dr. Sendoel studies the regulation of protein synthesis in cancer stem cells.  The synthesis of proteins from the messenger RNA code is referred to as translation; this is a key cellular process because the types and levels of proteins in a cell controls the cell’s function and health.  Dr. Sendoel uncovered a unique switch that hijacks this process during tumor formation and progression, forcing the cell to preferentially synthesize cancer-promoting proteins.  Interestingly, one of the genes involved in this switch is frequently amplified in patients with squamous-cell carcinomas, with higher levels correlating with shorter survival.  Motivated by these findings and his clinical experience, Dr. Sendoel is now developing drugs to block cells from making this switch in translation, which could lead to new strategies for cancer treatment and prevention.

“Cancer is still one of the leading causes of death. Although remarkable advances have been made in the last decade, there is still the need for novel insights and novel concepts that could be translated into novel cancer therapies. My long-term vision is to obtain a comprehensive understanding of how translational regulation determines cell fate in homeostasis and disease and translate this knowledge into novel strategies to treat human disease.”
