Good communication in English language, spoken and written.Project description:Paediatric high-grade gliomas that occur in the brainstem are one of the leading causes of cancer-induced mortality in children. A significant problem in the treatment of these tumours is the exclusion of surgery, as it would pose a great risk of disturbing the structures of the brainstem and potential loss of basic vital functions in patients. The main method of treatment is radiotherapy, i.e. precise ionizing radiation to the affected brain/tumour area, which damages the rapidly dividing cancer cells. However, radiotherapy only temporarily stops the disease, and in most cases, it recurs after a few months. Therefore, there is a great need to aid radiation therapy by developing drugs that would allow the complete elimination of cancer cells with minimal side effects for the patient.The mutation detected in histone H3 (termed H3K27M mutation) in childhood diffuse midline gliomas (H3K27-altered, DMGs) significantly disrupts H3 epigenetic modifications and thereby globally alters chromatin characteristics in these tumors, causes aberrant gene expression, which supports tumor growth. At the stage of diagnosis, DMGs are already very big, and have extensive regions with low oxygen levels, called hypoxia. Based on the research in other tumour types, we know that hypoxia has a huge impact on the epigenetic modification of histones and, ultimately, the packaging of DNA as well as the activation of individual genes. It is very important to understand the cellular responses to hypoxia in detail, as clinical data show that the greater the hypoxia of a tumour, the smaller are chances of the patient’s survival. The presence of hypoxia is also of particular importance in tumours treated with radiotherapy, as the lack of oxygen significantly reduces the harmfulness of ionizing radiation for cancer cells, which overall reduces the effectiveness of the therapy. Importantly, the role of hypoxia in tumorigenesis and therapy response has not been extensively studied in DMGs. In our project, we will focus on identifying the weak points in DMGs that depend on the presence of H3K27M oncohistone and are additionally important for the glioma cells in hypoxia. For this purpose, we will analyse the effect of hypoxia on epigenetic changes in histones, in DNA packaging and in the activation of gene expression in DMG cells with H3K27M. The laboratory has established collaboration with clinicians from the Warsaw Children’s Health Centre (IPCZD, Prof. Wiesława Grajkowska, Prof. Joanna Trubicka, extensive expertise with DMGs), as well as with international specialists in epigenetics (Prof. Jakub Mieczkowski, GUMED), in DMGs (Prof. Javad Nazarian, Zurich) and in H3K27M mutation (Prof. Jacek Majewski, Montreal).Scope of tasks:

• Characterization of chromatin reprogramming in response to hypoxia in DMG cells,
• Analysis of chromatin accessibility (ATACseq), selected histone modifications (CUT&RUN), DNA methylation and chromatin contacts (HiC), which are disturbed by hypoxia and the presence of H3K27M,
• Data analysis and keeping records of performed work,
• Keeping up to date with the new literature related to the project,
• Participation in writing manuscripts as well as presenting results at seminars and scientific conferences,
• Iindependent and creative undertaking of research challenges related to the project as well as working together with other team members.

Employment conditions:

• fixed-term employment contract (possibility of extension up to 5 years),
• starting date: from June 2025.
