PHILADELPHIA (February 18, 2019) — John Krais, PhD, a postdoctoral researcher at Fox Chase Cancer Center, recently received a two-year, $75,000 grant from the Ovarian Cancer Research Alliance (OCRA) for his investigation into DNA repair processes in BRCA1 mutant cancers.
Krais works in the lab of Neil Johnson, PhD, an associate professor at Fox Chase. His research will focus on the RNF168 protein, which is involved in repair of DNA damage. RNF168 recruits BRCA1 and another protein, 53BP1, to the site of DNA damage. 53BP1 blocks the BRCA1-dependent repair process, resulting in pathways that lead to more mutations in BRCA1 mutant cancers.
Preliminary research found reduced recruitment of 53BP1 to DNA damage in cases of BRCA1 mutation, allowing the cancer to grow. These same circumstances yielded a low presence of RNF168. By delving more into the role of RNF168, Krais will provide a better overall understanding of the DNA repair process in BRCA1 mutant cancers.
The BRCA1 and BRCA2 mutations are the strongest known genetic risk factors for epithelial ovarian cancer.
“I am grateful to the Ovarian Cancer Research Alliance and Phil and Judy Messing for enabling me to generate information that we hope will ultimately lead to accurate predictions of therapy response and novel therapeutic approaches,” said Krais.
