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 […]

Nature: EWS–FLI1 increases transcription to cause R-loops and block BRCA1 repair in Ewing sarcoma

March 7, 2018

Aparna Gorthi, July Carolina Romero, Eva Loranc, Lin Cao, Liesl A. Lawrence, Elicia Goodale, Amanda Balboni Iniguez, Xavier Bernard, V. Pragathi Masamsetti, Sydney Roston, Elizabeth R. Lawlor, Jeffrey A. Toretsky, Kimberly Stegmaier, Stephen L. Lessnick, Yidong Chen & Alexander J. R. Bishop Abstract Ewing sarcoma is an aggressive pediatric cancer of the bone and soft tissue. It results from a chromosomal translocation, predominantly t(11;22)(q24:q12), that fuses the N-terminal transactivation domain of […]

Cell Death & Disease: miR-195 targets cyclin D3 and survivin to modulate the tumorigenesis of non-small cell lung cancer

February 7, 2018

Xiaojie Yu, Yiqiang Zhang, David Cavazos, Xiuye Ma, Zhenze Zhao, Liqin Du & Alexander Pertsemlidis Abstract miR-195 has recently been reported to function as a tumor suppressor in various cancers, including non-small cell lung cancer (NSCLC). However, the mechanisms by which miR-195 represses the tumorigenesis of NSCLC cells are not fully understood. We performed a high-throughput […]

Childhood Obesity: Characterization of the Stool Microbiome in Hispanic Preschool Children by Weight Status and Time

February 1, 2018

Emily B Hollister 1 2, Byron A Foster 3, Mahmoud Dahdouli 1 2, Jesica Ramirez 4, Zhao Lai 5 Abstract Background: Variations in gut microbiota composition and diversity have been associated with childhood adiposity, although most studies describing this have been cross-sectional in nature. Our objective was to evaluate associations between body weight and the gut microbiota over time in obese preschool-age children. Methods: Obese, preschool-age, Hispanic children […]
