Nature Communications: MiR-584-5p potentiates vincristine and radiation response by inducing spindle defects and DNA damage in medulloblastoma

October 31, 2018

Nourhan Abdelfattah, Subapriya Rajamanickam, Subbarayalu Panneerdoss, Santosh Timilsina, Pooja Yadav, Benjamin C. Onyeagucha, Michael Garcia, Ratna Vadlamudi, Yidong Chen, Andrew Brenner, Peter Houghton & Manjeet K. Rao Abstract Despite improvements in overall survival, only a modest percentage of patients survive high-risk medulloblastoma. The devastating side effects of radiation and chemotherapy substantially reduce the quality of life for surviving patients. Here, using genomic screens, we identified miR-584-5p as a […]

Hinckley,1,11 Peter J. Houghton,3 and Ryan D. Roberts1,2,4 Abstract: Osteosarcoma (OS), a malignant tumor of bone, kills through aggressive metastatic spread almost exclusively to the lung. Mechanisms driving this tropism for lung tissue remain unknown, though likely invoke [...]

CRISPR – Journal: CRISPR-Based Editing Reveals Edge-Specific Effects in Biological Networks

August 1, 2018

 Yi Li, Chance M. Nowak, Daniel Withers, Alexander Pertsemlidis, Leonidas Bleris Abstract Unraveling the properties of biological networks is central to understanding both normal and disease cellular phenotypes. Networks consist of functional elements (nodes) that form a variety of diverse connections (edges), with each node being a hub for multiple edges. Herein, in contrast to node-centric network perturbation [...]
