“What is the link between metabolic disease and cancer?” 

The prevalence of obesity is increasing worldwide, with one in eight people living with obesity in 2022, according to the World Health Organization. Obesity affects our body’s metabolic processes, and can lead to insulin resistance, type 2 diabetes, and cardiovascular diseases.
Obesity is also a risk factor for several types of cancer and a promoter of cancer progression, although the biological mechanisms underlying this link remain incompletely understood.
Our research focuses on investigating these links using the model organism fruit fly Drosophila melanogaster. We aim to use the insights from Drosophila models as a basis for developing future strategies in cancer prevention and treatment.
