Breast cancer: Luminal cells with an identity crisis

Breast cancer: Luminal cells with an identity crisis

Gemma K. Alderton

Abstract
Inherited mutations in BRCA1 seem to specifically increase the risk of developing basal-like breast cancers; so, Proia and colleagues investigated how BRCA1 might promote the formation of this subtype of breast cancer.Using samples from reduction mammoplasty (BRCA1+/+) and prophylactic mastectomy from individuals with BRCA1 mutations (BRCA1mut/+), Proia and colleagues transformed cell suspensions with four tumorigenic genes (TP53R175H, CCND1, PI3KCA and KRASG12V) that are

Abstract
Medicine will move from a reactive to a proactive discipline over the next decade—a discipline that is predictive, personalized, preventive and participatory (P4). P4 medicine will be fueled by systems approaches to disease, emerging technologies and analytical tools. There will be two major challenges to achieving P4 medicine—technical and societal barriers—and the societal barriers will prove the most challenging. How do we bring patients, physicians and members of the health-care community into alignment with the enormous opportunities of P4 medicine? In part, this will be done by the creation of new types of strategic partnerships—between patients, large clinical centers, consortia of clinical centers and patient-advocate groups. For some clinical trials it will necessary to recruit very large numbers of patients—and one powerful approach to this challenge is the crowd-sourced recruitment of patients by bringing large clinical centers together with patient-advocate groups.
