NSF awards 22 new projects for plant genome research
...utheastern states. A number of functional genomics studies
will look at how genes contribute to the internal workings of an organism. A project at Pennsylvania State University, for example, will study the molecular genetic interactions between the rootstocks and scions of apple trees that affect the disease...
Certain genes boost fish oils' protection against breast cancer
...nd postmenopausal women. Interestingly, laboratory studies
have shown that cancer growth is suppressed by n-3 fatty acid byproducts, and the suppression is enhanced by drugs that increase lipid peroxidation. When antioxidants are introduce to battle the effects of peroxidation, though, the cancer continues t...
$2.7 million grant to support creation of virtual zebrafish atlas

of gene functions and disease. The comparisons to the images of healthy zebrafish will allow investigators to quickly detail the anatomical abnormalities associated with a variable manipulated in their experiments. The zebrafish, a common home-aqua...
ORNL's Delmau joins Technology Review's list of top young innovators

with two major pharmaceutical companies and is scheduled to ship its first systems to two preeminent research universities this week. According to Rimm, "AQUA is completely objective it takes the subjectivity out of pathology diagnosis." Rana ...
Research suggests new avenue for stopping, preventing colon cancer
...DuBois is internationally known for his pioneering studies
linking the development of colorectal cancer to the cyclooxygenase-2 (COX-2) enzyme. COX-2 is a major target for drugs that relieve the pain and inflammation of arthritis, but COX-2 gene expression is also elevated in a variety of malignancies includ...
Prion propagation: Avoiding the toxic oligomer

will have to explore this question, along with the issues of how oligomers figure into the process and how they cause disease. Weissman and colleagues raise the possibility that creating conditions that favor fiber growth while inhibiting oligomer fo...

with HhAntag offer the hope that such precise, targeted molecular interventions could spare children...
New anti-inflammatory strategy for cancer therapy identified by UCSD researchers
...Rebecca and John Moores UCSD Cancer Center. The studies
in mice with colon or breast cancer showed that cancer metastasis, the growth of malignant tumors beyond the original site, was halted with inhibition of either one of two naturally occurring substances, a pro-inflammatory protein called nuclear fact...

Picking prostanoids to provide protection
...rostanoids in inflammation is well known, based on studies
of aspirin-like non-steroidal anti-inflammatory drugs, which act to inhibit the action of COX. Two prostenoids called PG I2/prostacyclin (PGI2) and thromboxane A2 (TXA2), are ele-vated in individuals with atheroscle-rosis, but their roles in the ini...
