Top claims

  • ▪The Multiplexed Imaging of Nucleome Architectures (MINA) technique, developed by Siyuan Wang's lab, uses specialized microscopes to image DNA, RNA, and proteins together in intact ultrathin slices of tonsil tissue.
  • ▪Yale School of Medicine researchers are investigating which specific molecular factors are disrupted when somatic hypermutation goes haywire in B-cell lymphomas.
  • ▪When researchers rapidly degraded a protein holding the 3D chromatin loops together, somatic hypermutation in B cells completely stopped, though some looping interactions persisted and degraded more slowly.
