Current Protocols: Approaches for Mapping and Analysis of R-loops (Bishop Lab)

April 29, 2024

Pramiti Mukhopadhyay, Henry Miller, Aiola Stoja, Alexander J. R. Bishop Abstract R-loops are nucleic acid structures composed of a DNA: RNA hybrid with a displaced non-template single-stranded DNA. Current approaches to identify and map R-loop formation across the genome employ either an antibody targeted against R-loops (S9.6) or a catalytically inactivated form of RNase H1 (dRNH1), a nuclease [...]

Journal of the American Chemical Society: ights into Molecular Diversity within the FUS/EWS/TAF15 Protein Family: Unraveling Phase Separation of the N-Terminal Low-Complexity Domain from RNA-Binding Protein EWS (Libich Lab)

April 8, 2024

Abstract The FET protein family, comprising FUS, EWS, and TAF15, plays crucial roles in mRNA maturation, transcriptional regulation, and DNA damage response. Clinically, they are linked to Ewing family tumors and neurodegenerative diseases such as amyotrophic lateral sclerosis. The fusion protein EWS::FLI1, the causative mutation of Ewing sarcoma, arises from a genomic translocation that fuses [...]

Frontiers in Cell and Developmental Biology: Editorial: RNA-binding proteins in cancer: advances in translational research (Penalva)

March 27, 2024

Caterina Mancarella1* Nadine Bley2 Luiz O. F. Penalva3,4 RNA-binding proteins (RBPs) regulate RNA metabolism, processing, and translation by establishing highly dynamic interactions with hundreds of coding and non-coding target RNAs within ribonucleoprotein complexes (Van Nostrand et al., 2020). Alterations in RBP expression levels or function contribute to several pathological conditions, including cancer. Though underappreciated in the [...]

Genes & Cancer: Roles of USP1 in Ewing sarcoma (Shiio Lab)

February 13, 2024

Panneerselvam Jayabal1, Xiuye Ma1 and Yuzuru Shiio1,2,3 ABSTRACT Ewing sarcoma is a cancer of bone and soft tissue in children and young adults that is driven by the EWS-ETS fusion transcription factor, most commonly EWS-FLI1. We previously reported that Ewing sarcoma harbors two populations of cells, the CD133high population displaying higher growth rate and the CD133low population displaying [...]
