The structural features of an ancient ribonuclease from Salmo salar reveal an intriguing case of auto-inhibition.

Int J Biol Macromol 2021 Apr 10. Epub 2021 Apr 10.

Department of Biology, University of Naples Federico II, Complesso Universitario di Monte Sant'Angelo, Via Cintia, I-80126 Naples, Italy.

The superfamily of vertebrate ribonucleases, a large group of evolutionarily related proteins, continues to provide interesting structural and functional information. In particular, the crystal structure of SS-RNase-2 from Salmo salar (SS2), here presented, has revealed a novel auto-inhibition mechanism that enriches the number of inhibition strategies observed in some members of the family. Within an essentially unmodified RNase folding, the SS2 active site cleft is in part obstructed by the collapse of an extra pentapeptide inserted in the C-terminal region. Read More

Undiagnosed acromegaly as an underlying cause of sudden death.

Forensic Sci Med Pathol 2021 Apr 13. Epub 2021 Apr 13.

Department of Forensic Medicine, Section of Forensic Pathology, University of Copenhagen, Copenhagen, Denmark.

Improvement in plasma D-dimer level in severe SARS-CoV-2 infection can be an indicator of fibrinolysis suppression: Case reports.

Medicine (Baltimore) 2021 Apr;100(15):e25255

Department of Pathology and Laboratory Medicine, Cedars-Sinai Medical Center, Los Angeles, CA.

Rationale: Fibrinolysis shutdown associated with severe thrombotic complications is a recently recognized syndrome that was previously seldom investigated in patients with severe severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. It presents a unique therapeutic dilemma, as anticoagulation with heparin alone is insufficient to address the imbalance in fibrinolysis. And while the use of fibrinolytic agents could limit the disease severity, it is often associated with bleeding complications. Read More
