Disease relevance of BRCA1

 

High impact information on BRCA1

 

Biological context of BRCA1

 

Anatomical context of BRCA1

  • The present study examined immunohistochemically the expression and intracellular distribution of BRCA1 protein in two normal, seven dysplastic and 44 neoplastic canine mammary glands and its relationship with clinical and pathological variables and other prognostic parameters [4].
  • Strong nuclear immunolabelling of BRCA1 protein was observed in the epithelial cells of the normal mammary glands and mammary dysplasias [4].
 

Analytical, diagnostic and therapeutic context of BRCA1

  • The biological function of BRCA1 and factors affecting expressivity, such as gene-environment and gene-gene interactions, may be more effectively studied in appropriate animal models [1].
