Project title:

Mitochondrial double-stranded RNA: its origin, turnover and involvement in human diseases.

The project is carried out within the FIRST TEAM programme of the Foundation for Polish Science


Project description:

A postdoc position is available in the Laboratory of RNA Biology and Functional Genomics, Institute of Biochemistry and Biophysics of Polish Academy of Sciences in Warsaw. The laboratory is located in one of the best research institutions in Poland. The home institute is very well-equipped and localized in the Ochota research campus, where other life sciences institutes are placed.


We are looking for a highly motivated candidate who would like to join a mitochondrial research group working under the supervision of dr. Roman Szczesny. The main aim of the project is to gain insight into double-stranded RNA metabolism in human mitochondria.

In collaboration with a few other teams we have recently found that the transcription of the mitochondrial genome is a major source of dsRNA in humans (Dhir, Borowski…. Szczesny & Proudfoot, Nature, 2018). We discovered that dsRNA can be released from mitochondria, which results in activation of the innate immune system and can contribute to human disease. We revealed that the mitochondrial degradosome, a complex of RNA helicase SUV3 and ribonuclease PNPase, is responsible for controlling the levels of mitochondrial dsRNA (mt-dsRNA). To identify other proteins involved in mt-dsRNA metabolism we conducted a genome-wide siRNA screen, where the level of mt-dsRNA was measured by high-throughput fluorescent microscopy. This resulted in the identification of several putative factors related to mt-dsRNA, including known mtRNA players as well as proteins whose link to mtRNA metabolism was unexpected.

The project mostly builds on our yet unpublished results and will be the continuation of our research into dsRNA of mitochondrial origin. Our long term goal is to understand the molecular mechanisms of dsRNA metabolism in human mitochondria and explore potential links between mt-dsRNA and human diseases.


We offer ambitious scientific goals, friendly and stimulating scientific environment, well-equipped laboratory, ability to apply various research strategies (including high-throughput siRNA screenings, proteomics, NGS-based studies), strong support from the technical staff
