Description
In this episode of the Epigenetics Podcast, we caught up with Claudia Keller Valsecchi from the Institute for Molecular Biology in Mainz to talk about her work on gene dosage alterations in evolution and ageing.
Claudia Keller-Valsecchi's team focuses on understanding the fundamental mechanisms of how cellular function in eukaryotes is influenced by gene copy number variation. Recent findings indicate that precise MSL2-mediated gene dosage is highly relevant for organismal development. Since 2020 Claudia Keller-Valsecchi runs her own lab at the IMB in Mainz, Germany, where she tries to understand from a molecular mechanistic point of view how gene dosage compensation works, with projects in mosquitoes and in Artemia franciscanagene, as well as dosage regulation in the mammalian system regarding development and disease.
