A recent study, published in Autophagy, sheds light on the connection between autophagy and polyploidy and reveals that cells with several copies of DNA experience higher levels of autophagy, which can trigger programmed cell death.
Led by researchers at IRB Barcelona, the study offers insights into the biological processes shaping organisms during early development. Understanding the implications of polyploidy for embryonic development has significant potential impact on medicine, as it occurs in many species, including humans.

Progenitor cells, which can differentiate into various cell types, were studied in the Drosophila melanogaster fly model. In this organism, progenitor cells without polyploidy (a single copy of chromosomes) can survive metamorphosis and contribute to the adult organism. On the other hand, cancer cells often exhibit polyploidy, potentially conferring resistance to treatments like chemotherapy.
The research focused on the trachea of the Drosophila fly as a model, which contains different cell types, some with polyploidy and others without. By comparing cells of the same type with and without polyploidy, the researchers observed how polyploidy correlates with cell death during metamorphosis. The team is now working to determine whether polyploid cells respond better to stress and the mechanisms underlying this response.
