Areas of research


Proteotoxic stress and metabolism

Myeloma cells are characterised by a unique sensitivity to inhibitors of the proteasome, which is responsible for the controlled degradation of most cellular proteins that have become damaged or are otherwise unwanted. Nevertheless, resistance to proteasome inhibitors occurs in essentially all patients to varying degrees. Accumulation of misfolded proteins in the endoplasmic reticulum (ER), which triggers proteotoxic ‘ER stress’, is widely believed to be the main mechanism of action of proteasome inhibitors. However, data from our lab and other research groups suggest complex interactions between proteasomal protein degradation and multiple metabolic processes. Our aim is to find metabolic and proteostatic vulnerabilities that we can exploit therapeutically.


Tissue biophysics in myeloma biology

Several important aspects of cancer cell biology are influenced by mechanical cues from the surrounding tissue. In particular, mechanical interactions and matrix remodelling have been shown to govern cancer cell metabolism. Tissue stiffness also impacts on normal haematopoiesis, and mechanical cues are known to modulate therapeutic responses. Moreover, we have shown that proteostasis-targeting drugs can alter tissue physical properties. We aim to understand how tissue stiffness and nutrient availability act together to rewire metabolic networks and regulate drug responses in myeloma.

AB - In 2008, we published the first set of guidelines for standardizing research in autophagy. Since then, this topic has received increasing attention, and many scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Thus, it is important to formulate on a regular basis updated guidelines for monitoring autophagy in different organisms. Despite numerous reviews, there continues to be confusion regarding acceptable methods to evaluate autophagy, especially in multicellular eukaryotes. Here, we present a set of guidelines for investigators to select and interpret methods to examine autophagy and related processes, and for reviewers to provide realistic and reasonable critiques of reports that are focused on these processes. These guidelines are not meant to be a dogmatic set of rules, because the appropriateness of any assay largely depends on the question being asked and the system being used. Moreover, no individual assay is perfect for every situation, calling for the use of multiple techniques to properly monitor autophagy in each experimental setting. Finally, several core components of the autophagy machinery have been implicated in distinct autophagic processes (canonical and noncanonical autophagy), implying that genetic approaches to block autophagy should rely on targeting two or more autophagy-related genes that ideally participate in distinct steps of the pathway. Along similar lines, because multiple proteins involved in autophagy also regulate other cellular pathways including apoptosis, not all of them can be used as a specific marker for bona fide autophagic responses. Here, we critically discuss current methods of assessing autophagy and the information they can, or cannot, provide. Our ultimate goal is to encourage intellectual and technical innovation in the field.
