    Mutations in BRCA1 result in predisposal to breast and ovarian cancers, but many variants exist with unknown clinical significance (VUS). One is BRCA1 c.4096+3A>G, which affects production of the full-length BRCA1 transcript, while augmenting transcripts ...

    Germline mutations in BRCA2 increase the risk of breast and ovarian cancer. The BRCA2 protein is involved in maintaining genomic stability through its roles in DNA double strand break repair and protection of stalled replication forks. The BRCA2 gene ...

    Human breast cancer is believed to arise in luminal progenitors within the normal breast. A subset of these are double positive (DP) for basal and luminal keratins and localizes to a putative stem cell zone within ducts. We here present a new protocol ...

    Circular RNAs (circRNAs) are a class of RNAs that is under increasing scrutiny, although their functional roles are debated. We analyzed RNA-seq data of 348 primary breast cancers and developed a method to identify circRNAs that does not rely on unmapped ...

    Estrogen receptor-positive breast cancer is subdivided into subtypes LuminalA and LuminalB, based on different expression patterns. MicroRNA-190b has been reported to be up-regulated in estrogen receptor-positive breast cancers. In this study we aimed ...

    Recent studies indicate that lifestyle factors in early life affect breast cancer risk. We therefore explored the association of high consumption of meat, milk, and whole grain products in adolescence and midlife, on breast cancer risk. We used data ...
  • Kristbjornsdottir, Adalbjorg (University of Iceland, School of Health Sciences, Faculty of Medicine, 2016-12)
    Background and aims: Previous studies in geothermal and volcanic areas have shown high risk of certain types of cancers. The aim was to study the association between residence in geothermal areas and the incidence and mortality of cancer in ...

    The microenvironment is increasingly being recognized as a key player in supporting cancer progression. Therefore, investigating heterotypic interactions between cancer cells and their microenvironment is important for improving our understanding ...

    Background: Fusion genes result from genomic structural changes, which can lead to alterations in gene expression that supports tumor development. The aim of the study was to use fusion genes as a tool to identify new breast cancer (BC) genes with a ...

    Breast cancer (BC) is the most prevalent type of cancer in women in western countries. BC mortality has not declined despite early detection by screening, indicating the need for better informed treatment decisions. Therefore, a novel noninvasive ...

    Epithelial to mesenchymal transition (EMT) has implications in tumor progression and metastasis. Metabolic alterations have been described in cancer development but studies focused on the metabolic re-wiring that takes place during EMT are still limited. ...

    Metastatic progression is the leading cause of mortality in breast cancer. Invasive tumor cells develop invadopodia to travel through basement membranes and the interstitial matrix. Substantial efforts have been made to characterize invadopodia molecular ...
