Barazzuol group

Radiotherapy is an essential and highly effective part of the treatment of many cancers, including paediatric and adult brain tumours. Irradiation of normal brain tissue is, however, unavoidable and can result in major impairments of neurocognitive functioning and reduced quality of life. Similar effects occur after chemotherapy for brain and non-intracranial tumours.

Lara Barazzuol’s group focuses on assessing the effect of radiation (and chemotherapy) on the brain and aims to achieve an improved biological and molecular understanding of cancer treatment-induced neurocognitive dysfunction.

  • When using radiotherapy in the treatment of primary and metastatic brain tumours, damage of normal brain tissue is an unavoidable side effect. This can severely compromise cancer patients’ quality of life by diminishing their neurocognitive function, especially in cases of childhood brain tumours. The underlying mechanisms are not fully understood and, at present, there is no effective treatment.

    Lara Barazzuol’s lab, by using a combination of methodologies (ranging from brain organoids, bioinformatics, in vivo imaging and behavioural tests), aims to understand the underlying biological and molecular mechanisms of radiotherapy-induced neurocognitive dysfunction; and, to elucidate the effect of genetic variation on the pattern and severity of neurocognitive outcome based on clinical data.

    Another interest of Lara Barazzuol’s lab is investigating how defects in DNA repair impact on human health, with a particular focus on neurodegenerative diseases, and understanding how this knowledge can be exploited in the clinic.
