[HTML][HTML] Functional role of the microRNA-200 family in breast morphogenesis and neoplasia

B Hilmarsdottir, E Briem, JT Bergthorsson… - Genes, 2014 - mdpi.com
Branching epithelial morphogenesis is closely linked to epithelial-to-mesenchymal transition
(EMT), a process important in normal development and cancer progression. The miR-200 …

Different tumor types from BRCA2 carriers show wild-type chromosome deletions on 13q12–q13

J Gudmundsson, G Johannesdottir, JT Bergthorsson… - Cancer research, 1995 - AACR
In this study we examined loss of heterozygosity (LOH) on chromosome 13q12–13 in 50
tumors from BRCA2 carriers in five families showing strong evidence of linkage to BRCA2. In …

Functional analysis of BRCA1 C-terminal missense mutations identified in breast and ovarian cancer families

…, N Loman, JT Bergthorsson… - Human molecular …, 2001 - academic.oup.com
Germline mutations in the breast and ovarian cancer susceptibility gene BRCA1 are responsible
for the majority of cases involving hereditary breast and ovarian cancer. Whereas all …

Somatic deletions in hereditary breast cancers implicate 13q21 as a putative novel breast cancer susceptibility locus

…, G Johannesdottir, JT Bergthorsson… - Proceedings of the …, 2000 - National Acad Sciences
A significant proportion of familial breast cancers cannot be explained by mutations in the
BRCA1 or BRCA2 genes. We applied a strategy to identify predisposition loci for breast cancer …

S Ingthorsson, E Briem, JT Bergthorsson… - Journal of mammary …, 2016 - Springer
Understanding the complex events leading to formation of an epithelial-based organ such
as the breast requires a detailed insight into the crosstalk between epithelial and stromal …

[HTML][HTML] deltaNp63 has a role in maintaining epithelial integrity in airway epithelium

…, S Halldorsson, BE Benediktsdottir, JT Bergthorsson… - PloS one, 2014 - journals.plos.org
The upper airways are lined with a pseudostratified bronchial epithelium that forms a barrier
against unwanted substances in breathing air. The transcription factor p63, which is …
