    Uncovering ADP-ribosylation signaling pathways: implications for PARP7 in cancer
    Host: Lea Sistonen (

    Coffee and sandwich at 11:45, first come first served!


    Six PhD researchers and early-career postdocs are welcome to have a lunch in restaurant Mauno and discuss with Prof. Hottiger after the seminar. This is a great possibility to learn hosting skills in friendly environment and create connections for future. Everyone is welcome to join, BioCity Turku will offer the lunch.

    Hottiger lab investigates inflammatory signaling (e.g. oxidative stress) with special focus on the role of post-translations modifications (PTM) such as ADP-ribosylation in the regulation of inflammation. PTMs of proteins are thought to contribute to the observed complexity of cellular processes in animal and man. PTMs may help to explain the differences between e.g. worm and man, considering that the number and the nucleotide sequences of genes is rather comparable among animal species. Hottiger lab studies the patterns of ADP-ribosylation using cutting-edge systems biology approaches such as ADP-ribosyl-specific high-resolution and quantitative mass spectrometry that are developed in house or in collaboration with various colleagues worldwide. Furthermore, Hottiger lab investigates the players involved, such as writers, readers and eraser of ADP-ribosylation, as well as their target proteins that carry this PTM using state-of-the-art proteomics methods.
