variants in BARD1 were associated with moderate risks of breast cancer.
NPM1 (show NPM1 Proteins) downregulation by P-STAT5 (show STAT5A Proteins) is mediated by impairing the BRCA1-BARD1 ubiquitin ligase, which controls the stability of NPM1 (show NPM1 Proteins). In turn, decreased NPM1 (show NPM1 Proteins) levels led to suppression of p53 (show TP53 Proteins) expression, resulting in enhanced cell survival.
In MCF-7 cells BARD1 variants do vary considerably their cellular distribution and in their ability to influence apoptotic response to cisplatin.
substitutions that create a structurally intact BRCA1/BARD1 heterodimer that is inactive in vitro with all E2 enzymes. Other substitutions in BRCA1 or BARD1 RING domains result in hyperactivity, revealing that both proteins have evolved attenuated activity. Loss of attenuation results in decreased product specificity, providing a rationale for why nature has tuned BRCA1 activity.
Findings suggest that the study of AtROW1 in plant may provide a model for elucidating the functional mechanism of BARD1 in mammals.
BRCA1-BARD1 ligase activity and subsequent SMARCAD1 (show SMARCAD1 Proteins)-dependent chromatin remodeling are critical regulators of DNA repair in cancer cells.
Results suggest that BRCA1-associated RING domain protein 1 (BARD1) rs7585356 G>A polymorphism may be associated with nephroblastoma risk.
BARD1 rs6435862 T>G and rs3768716 A>G single nucleotide polymorphisms contribute to increased susceptibility to neuroblastoma (show ARHGEF16 Proteins), especially for children at age >/=12 months in a Southern Chinese population.
BRCA pathway germline mutation (in BRCA1, BRCA2 (show BRCA2 Proteins) or BARD1 genes) was present in 10 of the 42 investigated triple-negative breast cancer patients rendering them susceptible to homologous recombination deficiency.
Study presents four different pathogenic BARD1 variants identified in ovarian cancer patients. Three of them result in incorrect splicing of the corresponding exons, which may prompt expression of specific BARD1 isoforms and carcinogenesis.
Suggest BARD1 as a driver of proliferation and of pulmonary fibrosis pathogenesis.
identification of BARD1 as mediator between proapoptotic stress and p53 (show TP53 Proteins)-dependent apoptosis
the developmental functions of Brca1 (show BRCA1 Proteins) and Bard1 are mediated by the Brca1 (show BRCA1 Proteins)/Bard1 heterodimer.
Data show that expression of truncated mouse or human BARD1 peptides capable of interacting with Brca1 results in a homologous-repair deficiency.
the ankyrin and BRCT motifs of BARD1 are each essential for both chromosome stability and homology-directed DNA repair.
The remarkable similarities between the mammary carcinomas of Bard1-, Brca1 (show BRCA1 Proteins)-, and Bard1/Brca1 (show BRCA1 Proteins)-mutant mice indicate that the tumor suppressor activities of both genes are mediated through the BRCA1 (show BRCA1 Proteins)/BARD1 heterodimer.
This gene encodes a protein which interacts with the N-terminal region of BRCA1. In addition to its ability to bind BRCA1 in vivo and in vitro, it shares homology with the 2 most conserved regions of BRCA1: the N-terminal RING motif and the C-terminal BRCT domain. The RING motif is a cysteine-rich sequence found in a variety of proteins that regulate cell growth, including the products of tumor suppressor genes and dominant protooncogenes. This protein also contains 3 tandem ankyrin repeats. The BARD1/BRCA1 interaction is disrupted by tumorigenic amino acid substitutions in BRCA1, implying that the formation of a stable complex between these proteins may be an essential aspect of BRCA1 tumor suppression. This protein may be the target of oncogenic mutations in breast or ovarian cancer.
