Beskrivning
Do you want to contribute to top quality medical research?Overview of the Position
The Strategic Research Programme in Diabetes (SRP Diabetes) at Karolinska Institutet is funding a prestigious fellowship programme for postdoctoral research fellows. The Programme is focused on research in diabetes and its comorbidities. With this postdoctoral programme SRP Diabetes aims to support the next generation of exceptional young scientists within the diabetes area, including both experimental and clinical research. As part of this programme, we are looking to recruit 5 outstanding postdoctoral research fellows. Full details on each project and contact information to the PIs can be found at:http://ki.se/en/srp-diabetes/postdoctoral-fellowships
Based at Karolinska Institutet, fellows will undertake a cutting-edge research project in a competitive lab and be part of the SRP Diabetes dynamic research environment where several events will be held throughout the year such as high-profile lectures, symposia, internal retreat, etc. giving the fellows lot of opportunities to make new connections both within Karolinska Institutet and internationally within the field of diabetes and metabolism.
The fellowships are fully funded, and salary is provided for a 2-year period. It is our intention that the positions will start in the fall 2026, though some flexibility with the start date might be possible.
Short running title of project:mTORC1 signalling in insulin resistant human skeletal muscle
Research Project: "Mechanistic dysregulation of insulin responsive mTORC1 signalling in insulin resistant human skeletal muscle"
Insulin resistance in skeletal muscle is a core defect in type 2 diabetes, resulting in reduced glucose disposal and hyperglycaemia. Insulin resistance is also linked to altered muscle remodelling, reduced metabolic flexibility, and impaired adaptation to diet and exercise. We have recently taken an unbiased approach to deconvolute insulin signalling in skeletal muscle. Specifically, we applied deep proteomics and phosphoproteomics in human skeletal muscle during fasting and during hyperinsulinaemic euglycaemic clamps in a large, well phenotyped cohort across the insulin sensitivity spectrum. Strikingly, a key and unexpected pattern emerged. Several insulin-stimulated mTORC1 substrates tracked tightly with insulin sensitivity, whereas many AKT substrates remained insulin responsive even in insulin resistant muscle (Cell, 2025). This points to selective uncoupling of insulin signalling to mTORC1 rather than global proximal insulin signalling failure. Thus the aim of this post-doctoral project is to
Define an insulin responsive mTORC1 signature in human skeletal muscle across insulin sensitivity. Identify upstream regulators reducing mTORC1 signalling in insulin resistance Test causality in primary human skeletal muscle cells from insulin sensitive and insulin resistant donors.
mTORC1 is a central integrator of insulin, nutrients, growth factors, energy status, and cellular stress. It controls translation initiation, ribosomal biogenesis, autophagy, and aspects of intermediary metabolism. In skeletal muscle, mTORC1 also contributes to protein turnover and thus to muscle quality and function. In insulin resistant states, mTORC1 may be altered in two nonexclusive ways. First, insulin may fail to engage mTORC1 due to impaired coupling between AKT and the TSC complex, altered RPTOR based scaffolding, or altered localisation of the complex. Second, stress and nutrient sensing inputs may dominate over insulin input, shifting the operating point of the pathway. In vivo data from human studies that resolve these possibilities are scarce. One of mTOR's key roles is to regulate protein synthesis. Interestingly we have recently identified reduced expression of TMEM9-AS1 in skeletal muscle from people with type 2 diabetes, a lncRNA that appears necessary for adequate protein synthesis.
Key responsibilities of the selected applicant:
Plan, manage and conduct an agreed academic research project and associated activities.

Meritorious
Each Fellowship is for two years. To be eligible for employment as a post-doctor a doctoral degree or a foreign degree deemed to be equivalent to a doctoral degree is required. This eligibility requirement must be fulfilled at the latest at the time of the employment decision. It is considered as an advantage if you have completed your doctoral degree within the last three years, if there are special reasons, your degree may have been completed earlier.
What do we offer?
A creative and inspiring environment with wide-ranging expertise and interests. Karolinska Institutet is one of the world's leading medical universities. At Karolinska Institutet, we conduct successful medical research and hold the largest range of medical education in Sweden. At KI, you get to meet researchers working with a wide range of specialisms and methods, giving you ample opportunity to exchange knowledge and experience with the various scientific fields within medicine and health. It is the crossover collaborations, which have pushed KI to where it is today, at the forefront of global research. Several of the people you meet in healthcare are educated at KI. A close relationship with the health care providers is important for creating groundbreaking top quality education and research. Karolinska Institutet is also a state university, which entitles you to several benefits through our collective agreement.
