MIT researchers uncover surprising difference in gene regulation in mouse and human liver cells

Scientists often study mice as a model for human biology and disease, because their basic biological processes are assumed to be essentially the same as those of humans.

Biologist hopes mosquito can break viral chain

Most people do their best to avoid mosquitoes. But this summer Rollie Clem will play the wary host to his own homegrown swarm of Aedes aegypti, the yellow fever mosquito. He's made a room ready for them, and even a menu.

Decoding gene expression in cancer tumors using noninvasive imaging

By correlating images of cancerous liver tissue with gene expression patterns, a research team led by a radiologist at the University of California, San Diego (UCSD) School of Medicine has developed tools that may some day allow physicians to view a CT image of a cancer tumor and discern its genetic activity.

Chemotherapy drug temozolomide shrinks brain tumors

Cancerous brain tumors appear to respond favorably to the drug temozolomide when used as primary chemotherapy after surgery, and the treatment appears to work best in people missing a certain gene, according to a study published in the May 22, 2007, issue of Neurology, the scientific journal of the American Academy of Neurology.

Computer science sheds light on animal development

By applying the techniques of computer engineering to a mechanistic diagram describing the development of the Nematode C. elegans, a group of researchers in Switzerland has been able to tease out what laboratory experiments have not how and when the crucial cross-talk between cellular signaling pathways takes place in order to determine the fates of individual cells.
