Spatio-Temporal Alterations in Chromosome Dynamics (Jane Skok)

In this episode of the Epigenetics Podcast, we caught up with Jane Skok from New York University School of Medicine to talk about her work on spatio-temporal alterations in chromosome dynamics.

Studies demonstrating that nuclear organization and long-range chromatin interactions play essential roles in gene regulation have been the focus of the Skok Lab, where the team has played a leading role. Their initial studies focused on lymphocyte development and the control of V(D)J recombination, a key part of generating the diverse repertoire of B-cell antibodies and T-cell receptors. The Skok Lab was among the first to demonstrate the possibility of chromatin forming dynamic loops which lead to the formation of reversible intra-locus loops in the immunoglobulin and T-cell receptor loci and to a profound impact on the ability of B and T cells to generate receptor diversity.
