Some deadly breast cancers share genetic features with ovarian tumors

Posted: 23 Sep 2012 11:51 AM PDT

The most comprehensive analysis yet of breast cancer shows that one of the most deadly subtypes is genetically more similar to ovarian tumors than to other breast cancers. The findings suggest that most basal-like breast tumors and ovarian tumors have similar genetic origins and potentially could be treated with the same drugs.

Researchers solve puzzle of B-cell lymphoma development

Posted: 23 Sep 2012 11:51 AM PDT

In germinal centers, immune cells learn to fight pathogens with high specificity. Researchers have now identified subpopulations of B cells at the germinal centers which express the proto-oncogene Myc (red). They showed that Myc is essential for the formation and maintenance of germinal centers. Their findings have implications for the pathogenesis of B-cell lymphomas.

New chemistry technique reproduces nature's elusive complexity

Posted: 23 Sep 2012 11:18 AM PDT

Scientists have shown how to synthesize in the laboratory an important set of natural compounds known as terpenes. The largest class of chemicals made by living organisms, terpenes are made within cells by some of the most complex chemical reactions found in biology.

Researchers develop editing toolkit for customizing zebrafish genomes
