Off-pore Nup98 condensates mobilize heterochromatic breaks and exclude Rad51
Merigliano et al. identified a non-canonical, “off-pore” role for nucleoporins in genome stability and in the spatial regulation of homologous recombination in multicellular eukaryotes. Nup98 condensates form at DNA breaks within pericentromeric heterochromatin to prevent aberrant recombination by excluding Rad51, while promoting the mobilization of repair sites through immiscibility with heterochromatin protein 1 (HP1) condensates.

This RNA modification drives prostate cancer progression
Our recent study reveals that m6A RNA modification promotes prostate tumour growth and relapse. Specifically, it boosts the production of a cell movement molecule to aid cancer metastasis.
