How nuclear structure regulates transcription

Host: Subhash K. Tripathi (sukutr@utu.fi)

Our main goal is to unravel the nuclear events that drive peripheral activation of B lymphocytes. From genome-wide changes in epigenetics, chromatin architecture, and transcriptional activation, to recombination and hypermutation of antibody genes. Another major interest is to understand how deregulation of these mechanisms leads to B cell tumorigenesis. To achieve these goals, our team combines a wide range of cutting-edge technologies, including genome editing, nanoscopy, in situ Hi-C, cryo-EM, and bioinformatic tools.
