Kaisa Irene Lehti

Om

With background in biochemistry and cell biology, as well as in developing and applying cutting-edge technologies for tissue profiling, primary cell isolation, and 3D in vitro, ex vivo & in vivo experimental models, the Lehti group at NTNU focuses on basic and translational cancer research, tumor/tissue microenvironment (TME)-dependent cell signalling and phenotypic plasticity in cell growth, invasion, and drug resistance. The group collaborates actively on different aspects of clinical cancer diagnosis and therapy development particularly in (but not limited to) ovarian cancer.

Previous research

Since graduate studies at the University of Helsinki, Lehti’s scientific interest has been in the general and context-dependent mechanisms of cell invasion and tissue remodeling, with particular focus on the underlying proteolytic effectors and signals in cancer and pathological angiogenesis.

The observations in her PhD thesis established fundamental regulatory features of the membrane-type matrix metalloproteinase, MT1-MMP in cancer cells. Her postdoctoral research with Stephen J Weiss at the University of Michigan revealed the first physical and functional interaction of this protease, earlier considered mainly as a downstream effector of pro-invasive signaling, with receptor tyrosine kinase complexes.

With her research groups at the University of Helsinki, Karolinska Institutet, and NTNU, Lehti has focused on uncovering the molecular mechanisms of cancer invasion, growth control, and apoptosis evasion in varying extracellular matrices (ECM) and TMEs. The results have revealed unique mechanisms of 1) coordination between ECM degradation, adhesion, and signaling connected with cytoskeletal dynamics in collective invasion as well as epithelial-to-mesenchymal transition-induced invasion and metastasis, and 2) collagen assembly, cell aggregation and lymphatic involvement associated with poor cancer prognosis as well as proliferative diabetic retinopathy.

The group has identified a clinically relevant, co-targetable mechanism of FGFR4 oncogenic activity via evasion from cell stress-associated Hippo MST1/2 kinase-induced apoptosis. Using an oncology drug library and FGFR4 inhibitor, their results showed that FGFR4 encompasses co-targetable vulnerabilities with intrinsic apoptosis or EGFR, AKT & mTORC1 pathways. Moreover, they revealed a robust mechanism, whereby ovarian cancer cells develop TME-dependent chemotherapy resistance via an adaptive RSK-EphA2-GPRC5A signalling switch.

Coupled with collaborative studies on for example cytoskeletal signaling in cancer-associated fibroblasts and carcinomas, as well as fibrosis and immuno-microenvironment in aggressive sarcomas and proliferative diabetic retinopathy, Lehti’s results add to the comprehensive understanding of cell invasion, growth, and apoptosis, as well as the related drug responses & treatment options in different cancers and other fibro-inflammatory conditions.
