Phenotype Image Detail

Caption Deletion of Brca2 from prostate epithelia results in hyperplasia and low-grade prostate intraepithelial neoplasia (LG PIN). (A) Haematoxylin and eosin stained sections of dorsolateral prostate (DLP), ventral prostate (VP) and anterior prostate (AP) of control and Brca2tm1Brn/Brca2tm1Brn Tg(Pbsn-cre)4Prb/0 (Brca2F/F;PBCre4)) mutants. Control (Brca2F/F) and Brca2 heterozygous (Brca2F/+;PBCre4) prostates do not have PIN. Prostate-specific homozygous deletion of Brca2 (Brca2tm1Brn/Brca2tm1Brn Tg(Pbsn-cre)4Prb/0) results in focal hyperplasia and LG PIN (indicated with arrows). Black box shows the area shown in higher magnification in the panel below. (B) Detail of LG PIN in the DLP of Brca2 mutant prostates. Left panel shows a lumen with tufting pattern and right panel shows cribiform pattern. Arrowheads indicate atypical cells.
