Mechanisms of MAP kinase activation after diverse stress stimuli.
The molecular mechanisms responsible for activation of p38 and JNK after stress stimuli are vastly understudied compared to the mechanisms governing activation of these kinases after extra-cellular receptor-mediated stimulation. In an attempt to fill this gap in our understanding of cellular stress responses, we are working to identify the unknown or poorly studied signalling components working upstream of MAP kinases. To this end we employ siRNA screens and high-content microscopy techniques combined with a range of biochemical and cell biological techniques.

Identification of novel stress signaling pathways.
Employing proteomics, we are continuously searching for new cellular target of p38 and JNK signalling. We have uncovered a number of such targets, and we are currently undertaking detailed investigation of their biological ramifications. Several of these projects focus on RNA-binding proteins, and regulation of post-transcriptional gene regulation is a common denominator for many effector pathways in cellular stress as well as inflammatory responses.

Requirement of cellular stress responses for cancer development and tumour cell maintenance.
Cancer cells are more metabolically active than normal healthy cells, and consequently they have an increased requirement for functional stress signalling pathways to combat the detrimental effects of reactive oxygen species and other metabolic by-products. We hypothesize that these pathways will represent future targets for therapeutic intervention in cancer therapy. We are investigating these ideas in both cell culture and mouse models.
