Research Group Mechanisms of Cell Death and Drug Resistance

Hamed Alborzinia
Group Leader

It is now widely accepted that apoptosis is not the sole form of cell death, and additional modalities of cell death have been discovered in recent decades, including necroptosis, pyroptosis, and ferroptosis. The existence of multiple distinct non-apoptotic cell death pathways has raised numerous fundamental questions, which may help explain previously surprising observations that inactivating the apoptotic machinery does not entirely suppress cell death. This is particularly interesting in states relevant to cancer progression, driven, for example, by the oncogene MYC, or in drug-tolerant cancer cells that have been demonstrated to be sensitive to ferroptosis while resistant to apoptosis. One of our goals is to comprehend ferroptosis, a form of cell death distinguished by oxidative and metabolic processes, which involve selenocysteine uptake and metabolism. Selenocysteine is indispensable for the function of selenoproteins, such as GPX4, a vital regulator of ferroptosis that serves to inhibit lipid peroxidation. This could serve as a therapeutic strategy to selectively target drug-tolerant cancer cells, a subject of our research across various preclinical cancer models. Furthermore, we conduct multiple CRISPR screens across diverse cancer models in vitro and in vivo to elucidate drug resistance mechanisms. Utilizing cellular and animal models, we seek to unravel the complexity and heterogeneity of drug resistance in cancer. This comprehensive approach enables us to pinpoint novel targets for drug development and devise innovative therapeutic strategies, ultimately aiming to improve cancer patients' overall quality of life.

 

The group's primary aims include:

  • Unraveling the mechanisms associated with selenocysteine metabolism and ferroptosis.
  • Developing novel ferroptosis inducers.
  • Exploring the molecular mechanisms underlying drug resistance in cancer cells.
