Thrombosis Research: A cohort study on blood coagulation in childhood cancer survivors (Aune)

May 5, 2023

                   Andrew D. Meyer a, Tyler B. Hughes a, Anjana R. Rishmawi a, Patty Heard a, Shafqat Shah b, Gregory J. Aune b c Highlights Anticoagulants decrease thrombotic events in adults receiving cancer therapy. Survivors of childhood cancer have an increased risk of a thromboembolic stroke. Elevated coagulation protein levels are sensitive biomarkers of thrombosis risk. Our study identified that childhood survivors have chronically elevated [...]

PLOS GENETICS: Hepatic ribosomal protein S6 (Rps6) insufficiency results in failed bile duct development and loss of hepatocyte viability; a ribosomopathy-like phenotype that is partially p53-dependent (Chen)

April 6, 2023

 Sarah A. Comerford, Elizabeth A. Hinnant, Yidong Chen, Robert E. Hammer Sarah A. Comerford, Elizabeth A. Hinnant, Yidong Chen, Robert E. Hammer Abstract Defective ribosome biogenesis (RiBi) underlies a group of clinically diverse human diseases collectively known as ribosomopathies, core manifestations of which include cytopenias and developmental abnormalities that are believed to stem primarily from [...]

Biopolymers: Biochemical and biophysical characterization of the nucleic acid binding properties of the RNA/DNA binding protein EWS

March 21, 2023

 Emily E. Selig,  Roohi Bhura,  Matthew R. White,  Shivani Akula,  Renee D. Hoffman,  Carmel N. Tovar,  Xiaoping Xu,  Rachell E. Booth,  David S. Libich Abstract EWS is a member of the FET family of RNA/DNA binding proteins that regulate crucial phases of nucleic acid metabolism. EWS comprises an N-terminal low-complexity domain (LCD) and a C-terminal RNA-binding domain (RBD). The RBD is further divided [...]

Structure: Order and disorder bound together in SARS-CoV-2 Nsp1 suppress host translation (Libich Lab)

February 6, 2023

 David S Libich 1, Antoine Baudin 2 Abstract In this issue of Structure, Wang et al. investigate the interplay between folded and disordered regions of the SARS-CoV-2 non-structural protein 1 (Nsp1) that promotes the suppression of host protein translation. Their investigation will lead to novel avenues to target critical viral functions necessary for host immune-response suppression therapeutically. Read [...]
