Disease relevance of BRCA1

  • The performance characteristics of the amplified label-free electrochemical detection of DNA hybridization are reported in connection to measurements of nucleic-acid segments related to the breast-cancer BRCA1 gene [1].
  • CONCLUSIONS: In general, OC use, childbearing and breastfeeding do not differ between BRCA1/2 carriers and non-carriers with ovarian cancer [2].

High impact information on BRCA1

  • These results provide evidence that phosphorylation and nuclear relocalization are highly conserved features of the BRCA1 response to genotoxic stress [3].
  • Interestingly, when tested in the GAL4 transcriptional activation assay, full-length bovine and human BRCA1 lacked any ability to act as transcriptional activators and the CTD of bovine BRCA1 had five-fold lower activity when compared to the more acidic human C-terminus [3].
  • Human BRCA1 has a genetically demonstrated role in DNA repair, and has been proposed to act as a transcriptional activator in a limited number of specialized settings [3].
  • Expression was characteristically low and diffuse in the nucleus of G1/G0 cells, followed by increasing BRCA1-positive nuclear speckles in late S phase and G2/M phase cells [3].
