Enhanced luminal breast tumor response to antiestrogen therapy

Breast cancer can be divided into 4 major subtypes using molecular and genetic information from the tumors. Each subtype is associated with different prognosis and should be taken into consideration when making treatment decisions. In this issue of the Journal of Clinical Investigation, Rebecca Cook and colleagues at Vanderbilt University, found that expression of an oncogene, ERBB3, was enhanced in luminal breast cancers compared to other breast cancer subtypes. Addition of the ERBB3 protein to cultured luminal breast cancer cells increased the growth of the cells; however, depletion of this protein with an antibody promoted cancer cell death, and decreased tumor growth in vitro. The authors also demonstrated that ERBB3 was upregulated in luminal tumor samples and in cancer cell cultures that were treated with the cancer drug fulvestrant. Furthermore, the authors found that fulvestrant treatment in combination with anti-ERBB3 decreased both tumor cell survival and growth. These data suggests that ERBB3 could be a target for treatment of fulvestrant resistant breast cancers.

Peritoneal dialysis as an intervention for stroke patients

Ischemic stroke is characterized by an interruption of the blood supply to the brain, which can lead to brain damage and even death. Excess amounts of the excitatory neurotransmitter glutamate are released during stroke events and further exacerbate brain cell death. Currently, there are no effective strategies for combatting the effects ischemic stroke. In this issue of the Journal of Clinical Investigation, José Sánchez-Prieto and colleagues at the Universidad Complutense demonstrate that peritoneal dialysis is an effective treatment for reducing glutamate levels in the blood following a stroke event. In a rat model of ischemic stroke, peritoneal dialysis reduced tissue damage in the brain. Furthermore, the authors found that peritoneal dialysis was able to reduce blood glutamate levels in humans undergoing dialysis for chronic kidney disease, Together, these data suggest that peritoneal dialysis immediately following ischemic stroke may help preserve brain tissue and function.
