Biography
I am Senior Lecturer/Associate Professor in the School of Cancer Sciences and the CRUK Beatson Institute, University of Glasgow, U.K., with an interest in hematopoietic stem cell ageing, consequences on immune cell composition and senescence alongside age-associated clonal haemopoiesis on a functional, metabolic, and transcriptional level. We recently paved the way towards a predictor for clonal haematopoiesis outcomes by following the Lothian Birth cohort participants longitudinally over 15 years, showing that gene-specific fitness can outweigh inter-individual variability (Robertson et al 2022 Nature Medicine, Robertson et al Current Biology 2019). Moreover, we demonstrated functional diversity in senescence using single cell RNA-sequencing approaches. We show that primary and secondary senescence are distinct molecular endpoints with a blunted secretory phenotype and the induction of fibrillar collagens in secondary senescence pointing towards functional diversification (Teo et al 2019, Cell Reports).
I also lead the Single Cell Advanced Technologies facility at the School of Cancer Sciences, University of Glasgow.
I obtained my Ph.D. from the University of Edinburgh, characterising one of the first DNA damage-dependent premature ageing mouse models (Kirschner et al. DNA repair 2007, AntiCancer Res 2010). During my post-doc at the CRUK Cambridge Institute, I revealed previously unanticipated levels of complexity in p53’s response to stress, identifying specific transcriptional patterns in senescence (Kirschner et al. PLOS Genetics 2015). Seeking a more readily translatable disease model and appreciating the pioneering history of leukaemia studies for understanding cancer I joined Prof. Anthony Green’s lab at the University of Cambridge. Ageing is the biggest single cause for cancer, and I therefore combined my expertise in ageing and cancer leading the way in identifying JAK/STAT driven transcriptional clonal haemopoiesis by single cell RNA-seq (Kirschner et al. 2017 Cell Rep). I was also the experimental lead to develop now widely used tool for single cell RNA-seq data analysis (Kiselev, Kirschner et al, Nat Methods 2017).
Research interests
Kristina is interested in the interplay between stem cell ageing and cancer, using a variety of model systems.
Current research themes are:
- Elucidating metabolic vulnerabilities in HSCs from in myeloproliferative disease (Ph.D. student)
- 2. Age-related clonal haemopoiesis in the Lothian Birth Cohorts (Ph.D. student)
We combine single cell omics and metabolomics approaches to interrogate properties of haematopoietic stem cells in vitro and in vivo in myeloproliferative disease context.
Clonal hematopoiesis of indeterminate potential (CHIP) in healthy individuals increases rapidly from age 60 onwards and has been associated with increased risk for malignancy. CHIP is driven by somatic mutations in stem cells that are implicated in leukemia. We elucidate differences in stem cell fitness caused by different mutations on the molecular and functional level in vitro and in vivo.
- 3. Tumour microenvironment in acute lymphoblastic leukaemia (post-doc)
- 4. Pathways to senescence heterogeneity (Ph.D. student)
Our overarching purpose is to understand better how stromal cells influence and are influenced by cancer cells. We interrogate the relationship between cancer-associated fibroblasts from bone marrow mesenchymal stromal cells and acute lymphoblastic leukaemia in vitro and in vivo.
By using co-culture in vitro approaches and advanced mouse models of secondary senescence, we aim to define molecular signatures of primary and secondary senescence.
- Senescence heterogeneity in liver cancer (Ph.D. student)
We investigate the role of stromal cell primary and secondary senescence in liver cancer initiation, progression and resistance to chemotherapy in the context of therapy induced senescence using single cell omics approaches, in vitro co-culture models and advanced mouse models.
