A new take on growth factor signaling in tamoxifen resistance

Differences in growth factor (GF) signaling may cause the poor prognosis in some breast cancer cases. A new study, published in the open access journal BMC Medical Genomics, suggests that some estrogen receptor-positive breast cancers respond poorly to tamoxifen because of increased GF signaling.

Scientists launch Gene Expression Atlas

Today, researchers at the European Molecular Biology Laboratory's European Bioinformatics Institute (EMBL-EBI) launch a new database, the Gene Expression Atlas, which allows scientists to search and compare gene expression data at unprecedented detail and scope. Observing how gene expression varies in different cell types, tissues and under disease conditions can help researchers understand gene function and to develop new drugs and therapies.

Drug derived from the hydrangea root shows promise for autoimmune disorders

A drug derived from the hydrangea root, used for centuries in traditional Chinese medicine, shows promise in treating autoimmune disorders, report researchers from the Program in Cellular and Molecular Medicine and the Immune Disease Institute at Children's Hospital Boston (PCMM/IDI), along with the Harvard School of Dental Medicine.

Cancer vaccine efficacy enhanced using anti-diabetic drug Metformin

After a vaccination or an infection, the human immune system remembers to keep protecting against invaders it has already encountered, with the aid of specialized B-cells and T-cells. Immunological memory has long been the subject of intense study, but the underlying cellular mechanisms regulating the generation and persistence of long-lived memory T cells remain largely undefined. Now, University of Pennsylvania School of Medicine researchers have found that a common anti-diabetic drug might enhance the effectiveness of vaccines. The findings are described this week in an advanced online publication of Nature.

Getting more from whole-transcript microarrays

The widely-used Affymetrix Whole-Transcript Gene 1.0 ST (sense target) microarray platform, normally used to assay gene expression, can also be utilized to interrogate exon-specific splicing. Research published today in the open access journal BMC Bioinformatics shows scientists how to monitor alternative splicing activity on a genome-wide scale, without investing in new exon microarray technologies.
