Nanoparticles bearing inhibitory RNA may have potential for stopping premalignant breast lesions from progressing to invasive cancers, report scientists from several Boston-based institutions (Brock A et al. Sci Transl Med. 2014;6:217ra2.)
Using computer analyses to screen gene expression patterns and identify changes that occur during tumorigenesis in mammary tissue, the researchers identified the HoxA1 gene as a driver of early breast cancer progression. Past work also suggests that this gene might play an important role in breast cancer development.
