Do you want to contribute to top quality medical research?
To be a doctoral student means to devote oneself to a research project under supervision of experienced researchers and following an individual study plan. For a doctoral degree, the equivalent of four years of full-time doctoral education is required.
The research group
The position will be placed in the laboratory of Prof. Eckardt Treuter which conducts pre-clinical research at the crossroads between epigenomics, metabolism, inflammation and disease. Our research aims at better understanding how the epigenome controls metabolic and inflammatory pathways in the context of obesity, type 2 diabetes, fatty liver disease and atherosclerosis. Epigenetic alterations that trigger changes in epigenome activity and gene expression are fundamental reprogramming events that contribute to the development of these diseases. However, the underlying regulatory mechanisms, the critical components, and the causal relationship of these associations are currently poorly defined. With an emphasis on so-called coregulators we address these issues utilizing a multidisciplinary approach, including molecular biology, biochemistry, genomics and epigenomics approaches, genetically modified cell, tissue and mouse models, and collaborations with clinicians to study human material. We also develop proof-of-concept models for the therapeutic targeting of epigenome components, such as chromatin-modifying complexes and enhancers.
The laboratory is placed in the Department of Biosciences and Nutrition at Karolinska’s South Campus, a creative and open environment.
The doctoral student project and the duties of the doctoral student
AIM: This PhD project will investigate the role of macrophage epigenome alterations in the progression of atherosclerosis. Focus will be on two interconnected epigenome components, i.e. (1) a fundamental corepressor complex containing G-protein pathway suppressor 2 (GPS2), and (2) selected pro-atherogenic (inflammatory, metabolic) enhancers that are controlled by the complex (reviewed in Treuter et al. FEBS letters 2017).
RATIONALE AND HYPOTHESIS: Circulating monocytes and monocyte-derived tissue macrophages control inflammation and cholesterol efflux, key processes involved in atherogenesis. Previous work of the laboratory (e.g. Jakobsson et al. Mol Cell 2009, Venteclef et al. Genes Dev 2010; Fan et al. Nat Med 2016, Huang et al., FASEB J 2019; Liang et al Nat Comm 2019) has revealed that both processes are in part controlled by the subunit GPS2, within distinct corepressor sub-complexes, in macrophages. Epidemiological evidence suggests that obesity and type 2 diabetes are risk factors for developing cardiovascular diseases. Since our work additionally revealed that the expression and function of GPS2 in monocytes/macrophages is altered in obesity and type 2 diabetes, there could be a causal link between these alterations and epigenome/enhancer activity in re-programming gene expression to drive atherogenesis.
SIGNIFICANCE: The project is expected to increase our understanding of the atherogenic macrophage epigenome and the epigenetic mechanisms, including ‘memory’, that link obesity/type 2 diabetes and cardiovascular disease/atherosclerosis. Thereby, the project may contribute to the development of epigenome-based therapeutic strategies that specifically target pro-atherogenic pathways in monocytes/macrophages.
The PhD student will establish and manipulate human monocyte-derived macrophages in vitro to identify GPS2-dependent and -independent epigenome/enhancer alterations with an emphasis on relevance for atherogenic pathways in humans. This involves the application of latest CRISPR/Cas-9 techniques to modulate chromatin structure and activity, along with ChIP-seq, ATAC-seq, RNA-seq, ChIP-mass spectromentry and bioinformatics analysis. Ideally, the student will gain both wet and dry lab experience during the course of the PhD. At later project stages and in collaboration with postdocs, the student will also explore the in vivo role of the identified macrophage enhancers in atherogenic mouse models (ApoE ko, Ldlr ko, PCSK9).
