[...]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 [...]Cell Reports: Nitric Oxide Suppression by Secreted Frizzled-Related Protein 2 Drives Retinoblastoma (Shiio & Houghton Labs)

Salvador Alejo, Bridgitte E Palacios, Prabhakar Pitta Venkata, Yi He, Wenjing Li, Jessica D Johnson, Chen Yihong, Sridharan Jayamohan, Uday P Pratap, Kyra Abstract Background Efficient DNA repair in response to standard chemo and radiation therapies often contributes to GBM therapy resistance. Understanding the mechanisms of therapy resistance and identifying the drugs that enhance the [...]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.

January 3, 2023
Nicole R. Hensch, Kathryn Bondra, Long Wang, Prethish Sreenivas, Xiang R. Zhao, Paulomi Modi, Angelina V. Vaseva, Peter J. Houghton, Myron S. Ignatius Abstract In fusion-negative rhabdomyosarcoma (FN-RMS), a pediatric malignancy with skeletal muscle characteristics, >90% of high-risk patients have mutations that activate the RAS/MEK signaling pathway. We recently discovered that SNAI2, in addition to [...]Genes & Cancer: Slit2 signaling stimulates Ewing sarcoma growth
