Granular component sub-phases direct ribosome biogenesis in the nucleolus

Priyanka Dogra, Mylene C. Ferrolino, Suparna Khatun, Qi Miao, Michele Tolbert, Aaron Pitre, Shondra M. Pruett‐Miller, Swarnendu Tripathi, David W. Baggett, Jaison John, George E. Campbell, Katelyn Jackson, Richa Bajpai, Toler Freyaldenhoven, Eric B. Gibbs, , Richard W. Kriwacki

The paper uses super-resolution microscopy to show that nucleolus granular component sub-phases are organized into multiphase condensates that facilitate ribosome subunit assembly.

PARP1 directly disassembles nucleosomes to regulate DNA repair

Ashish Verma, Changlei Zhu, Bernadette Truong, Silvija Bilokapić, Rebekah DeVries, Aaron Pitre, Anang A. Shelat, Mario Halić, Hai Thanh Dao

This study identifies PARP1's direct role in evicting histone dimers from nucleosomes to generate open chromatin intermediates that facilitate DNA repair.

Suppression of non-canonical autophagy induces endothelial and cardiac dysfunction

Joëlle Magné, Suresh Poudel, Rona J. Strawbridge, Luigi Mari, Maria Sabater‐Lleal, Clifford S. Guy, Thomas Confer, Melissa Johnson, Mia Panlilio, Jaison John, Nicolas Denans, Pashupati Prasad Mishra, Joey Ward, Aaron Pitre, Aaron Taylor, , Douglas R. Green

This study shows that disrupting non-canonical autophagy (LANDO) impairs endothelial and cardiac function by disrupting VEGFR2 recycling and Hb- expression.
