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 […]

Here, we generated tp53 deleted […]

Technology Networks: Link Discovered Between BRCA1 Protein and Aggressive Pediatric Cancer

March 8, 2018

Scientists with the Greehey Children’s Cancer Research Institute at UT Health San Antonio have discovered a surprising connection between a breast cancer protein, BRCA1, and pediatric cancer called Ewing sarcoma. Their findings, reported March 7 in the journal Nature, reveal a completely new mechanism by which BRCA1 can be rendered dysfunctional. “The observations raise many new […]


UT Health SA Newsroom: Greehey Institute team finds link between BRCA1 and Ewing sarcoma

March 7, 2018

A mutant oncogene in Ewing traps BRCA1 and prevents it from repairing genetic damage. Scientists with the Greehey Children’s Cancer Research Institute at UT Health San Antonio have discovered a surprising connection between a breast cancer protein, BRCA1, and a pediatric cancer called Ewing sarcoma. Their findings, reported March 7 in the journal Nature, reveal a completely new mechanism […]
