Using Structural Biology to Understand Cell Signalling
Welcome to the Guettler Lab! We employ biochemistry, structural biology and cell biology to study the molecular mechanisms of Wnt/beta-catenin signalling and telomere homeostasis, with a particular focus on how poly(ADP-ribosyl)ation (PARylation) controls both processes. Besides understanding fundamental mechanisms of cell function, we aim to uncover novel potential therapeutic avenues in cancer.Selected Publications

Pathways to Independence and Dean’s Award to Postdoctoral Fellow Michael Ranes
Postdoctoral Fellow Michael Ranes has been awarded a place at the prestigious Pathways to Independence training programme, a joint initiative by the ICR, Sanger, MRC, and Cancer Research UK institutes and the Babraham Institute. The programme provides training for future scientific leaders. Michael has also received a £5,000 Dean’s Award to develop his independent research programme. Congratulations Michael!
Welcome William and Oviya!
Our lab is growing. We welcome Oviya Inian and William (Billy) Fisher into the lab. Oviya is a Postdoctoral Fellow who joins our telomere team. Billy joins us for a two-month summer project funded by a Lister Institute Summer Studentship.
