Breast cancer patients could find out whether they will respond positively to chemotherapy treatment by testing for the activity of certain genes. In a study published today in the Open Access journal, Journal of Translational Medicine, researchers analysed the genes expressed in the tumours of eighty-three patients with primary breast cancer. The researchers were able to predict which breast tumours would improve from chemotherapy in all cases of partial remission and nearly three quarters...

CHAMPAIGN, Ill. -- Using newly available biological technology, researchers have developed the first molecular portrait of multiple gene activity in diseased heart tissue taken from dogs near death from a devastating disease. The discovery sheds new light on the heart's response to dilated cardiomyopathy (DCM), a disease of large-breed dogs. New microscopic technology allows researchers to place tens of thousands of genes on 1.5-inch-square slides known as a microarray. In this case,...

CAMBRIDGE, Mass. - Just as the printing press revolutionized the creation of reading matter, a "nano-printing" technique developed at MIT could enable the mass production of nano-devices currently built one at a time. The most immediate candidate for this innovation is the DNA microarray, a nano-device used to diagnose and understand genetic illnesses such as Alzheimer's, viral illnesses such as AIDS, and certain types of cancer. The ability to mass produce these complex devices would make...
