Cell Reports: EWSR1 Maintains Centromere Identity (Kitagawa & Houghton labs)

May 30, 2023

Risa Kitagawa 1, Yohei Niikura 1 2, Argentina Becker 1 3, Peter J. Houghton 1, Katsumi Kitagawa 1 4 Highlights EWSR1 is required to maintain CENP-A at the centromere in interphase cells EWSR1 binds to CENP-A through the SYGQ2 region, important for phase separation EWSR1 binds to R loops in vitro through its RNA-recognition motif (RRM) EWSR1 protects CENP-A in the centromeric chromatin by binding to centromeric RNAs Summary The centromere is essential [...]

Nature Communications: Genomic disparities between cancers in adolescent and young adults and in older adults (Wang, Langevin, Houghton, & Zheng)

December 6, 2022

Xiaojing Wang, Anne-Marie Langevin, Peter J. Houghton & Siyuan Zheng Cancers cause significant mortality and morbidity in adolescents and young adults (AYAs), but their biological underpinnings are incompletely understood. Here, we analyze clinical and genomic disparities between AYAs and older adults (OAs) in more than 100,000 cancer patients. We find significant differences in clinical presentation between [...]
