Pioneering Point-Of-Care Testing for Integration of Germline and Tumor Genetics in Breast Cancer Risk Management: A Vision for the Future of Translational Pharmacogenomics.

Research performed in South African (SA) breast, ovarian and prostate cancer patients resulted in the development of a rapid BRCA point-of-care (POC) assay designed as a time- and cost-effective alternative to laboratory-based technologies currently used for first-tier germline DNA testing. In this study the performance of the new assay was evaluated for use on a portable screening device (ParaDNA), with the long-term goal to enable rollout at POC as an inventive step to meet the World Health Organization's sustainable development goals for Africa. DNA samples for germline testing were obtained retrospectively from 50 patients with early-stage hormone receptor-positive breast cancer referred for genomic tumor profiling (MammaPrint).

Changes in differential gene expression during a fatal stroke.

We present a young woman (with an identical twin sister) who arrived at the Emergency Department (ED) within 1 hour of her initial stroke symptoms. Previous microarray studies have demonstrated differential expression of multiple genes between stroke patients and healthy controls. However, for many of these studies there is a significant delay between the initial symptoms and collection of blood samples, potentially leaving the important early activators/regulators of the inflammatory response unrecognised.

Genomic responses during acute human anaphylaxis are characterized by upregulation of innate inflammatory gene networks.

Background: Systemic spread of immune activation and mediator release is required for the development of anaphylaxis in humans. We hypothesized that peripheral blood leukocyte (PBL) activation plays a key role.

Objective: To characterize PBL genomic responses during acute anaphylaxis.
