Elderly Liver Grafts are More Susceptible to Ischemia‐Reperfusion After Prolonged Cold Ischemia than Grafts from Young Donors—An Ex Vivo Liver Machine Perfusion Analysis in Sprague Dawley Rats

Advanced Therapeutics, EarlyView.
This study investigates how donor age and cold ischemia time influence liver perfusion parameters and injury markers. Older livers are more susceptible to longer ischemia times displaying more tissue damage, and higher expression of oxidative stress and apoptosis‐related proteins than livers with shorter ischemia times.

A role for SUMO modification in transcriptional repression and activation [PDF]

, 2007
Since the discovery of the SUMO (small ubiquitin-like modifier) family of proteins just over a decade ago, a plethora of substrates have been uncovered including many regulators of transcription.

Phase‐Separation of YAP Mediates AJUBA Super Enhancer Activation to Promote Aberrant Mitosis in Breast Cancer

Advanced Science, EarlyView.
YAP undergoes phase separation to activate the AJUBA super‐enhancer, driving aberrant mitosis through spindle checkpoint dysregulation in breast cancer. This study uncovers a mechanistic link between YAP condensates, super‐enhancer activation, and aneuploidy formation.

Excessive DNA Double‐Strand Breaks–Associated 3D Genome Reorganization Contributes to Neural Tube Defects with Folate Deficiency

Advanced Science, EarlyView.
Neural tube defects (NTDs) are among the most common congenital malformations. However, the underlying etiology and mechanism remain elusive. Here, the role of DNA double‐strand breaks (DSBs) in 3D genome organization within the NTDs with folate deficiency is reported.

Characterization of Agrobacterium tumefaciens DNA ligases C and D

Nucleic Acids Research, 2007
Agrobacterium tumefaciens encodes a single NAD+-dependent DNA ligase and six putative ATP-dependent ligases. Two of the ligases are homologs of LigD, a bacterial enzyme that catalyzes end-healing and end-sealing steps during nonhomologous end joining ...

Arginyltransferase, Its Specificity, Putative Substrates, Bidirectional Promoter, and Splicing-derived Isoforms [PDF]

, 2006
Substrates of the N-end rule pathway include proteins with destabilizing N-terminal residues. Three of them, Asp, Glu, and (oxidized) Cys, function through their conjugation to Arg, one of destabilizing N-terminal residues that are recognized directly by

Flavin Biosynthesis Enhances Extracellular Electron Transfer in Bioengineered Escherichia coli

Advanced Science, EarlyView.
Microbial electronics are promising for energy, sensing, environmental, and synthesis applications. E. coli are engineered with extracellular electron transfer (EET) pathways from a microbe that naturally produces current to enable bioelectronics based on E. coli.

How SUMOylation Fine-Tunes the Fanconi Anemia DNA Repair Pathway

Frontiers in Genetics, 2016
Fanconi Anemia (FA) is a rare human genetic disorder characterized by developmental defects, bone marrow failure and cancer predisposition, primarily due to a deficiency in the repair of DNA interstrand crosslinks (ICLs).
