Army of In Silico Tuberculosis Agents Must Battle to Win Over Experimentalists 6/03/04

June 3, 2004 11:49 am | Articles | Comments

by Catherine Shaffer Treatment for tuberculosis (TB) involves a grueling course of antibiotics that can last a year or more, and there is no effective vaccine. Because the disease manifests differently in humans than in animals, there are also no practical animal models for testing new treatments or vaccines. Now a team of scientists from the University of Michigan, Ann Arbor, Mich., have created a mathematical model of this intractable bacterial...

Chaperone Protein Dissolves Amyloid Plaques 6/02/04

June 2, 2004 8:23 am | Articles | Comments

by Catherine Shaffer Researchers at the Whitehead Institute for Biomedical Research, Cambridge, Mass., have reported in Science Express that yeast chaperone Hsp104 regulates the formation of amyloid fibers by Sup35, a translation termination factor. Sup35 converts to a prion, and the prion form aggregates into beta-sheet-rich amyloid fibers.

Researchers Eye Protein Suspects in Cell Death 06/01/04

June 1, 2004 12:54 pm | Articles | Comments

By Mark Terry Cells have a finite number of divisions, and at each division, chromosome ends, or telomeres, shorten. When the telomeres diminish to a certain length, a number of complex pathways are triggered that halt cell division. In cancer, though, this signaling pathway is disrupted, resulting in unrestrained cell growth.

Cilia May Provide Targets for Obesity and Other Diseases 5/27/04

May 27, 2004 12:01 pm | Articles | Comments

by Catherine Shaffer Two groups of researchers, working independently and using comparative genomic methods, identified a host of genes involved in the formation of cilia and flagella. Defects in these microtubule-based structures, which humans share with all animals and many unicellular organisms such as the algae Chlamydomonas, are blamed for various disorders, such as poor sperm motility, respiratory disorders, kidney disease, and blindness. The...

Drug Resistance Gene May Be Linked to Alzheimer’s Disease Onset 5/26/04

May 26, 2004 11:58 am | Articles | Comments

by Mark Terry Researchers at the Fox Chase Cancer Center, Philadelphia, linked Alzheimer's disease (AD) to a protein that helps cancer cells resist anti-tumor drugs. The protein, ABCA2, is associated with resistance to the cancer drug estramustine. It has also been linked to myelination and nervous system development. Involved in cellular transport, ABCA2 has also been associated with cholesterol loading. A recent report suggests there may be a...

Visualization Tool with Gene Expression Levels Planned for MetaCyc Database 5/25/04

May 25, 2004 11:18 am | Articles | Comments

by Jill Taylor With help from a grant from the National Institute of General Medical Sciences, the MetaCyc database, a metabolic pathway database that allows researchers to visualize metabolic pathways from more than 230 organisms, will soon be expanding both its content and the supporting software tool kit to provide additional querying capabilities, and a richer set of visualizations.

Enzyme Singles Out Misfolded Proteins 5/24/04

May 24, 2004 12:06 pm | Articles | Comments

by Elizabeth Tolchin Researchers identified an enzyme that plays a key role in the recognition of misfolded proteins. The finding, say the researchers, may offer a potential target for several degenerative diseases, including cystic fibrosis, diabetes, and Alzheimer's disease.

Inverse Relationship Between pRb2 and VEGF Expression May Diagnose Liver Cancer 5/20/04

May 20, 2004 11:54 am | Articles | Comments

by Mark Terry Researchers identified a relationship between the inverse expression of pRb2/p130 and vascular endothelial growth factor (VEGF) and tumor aggressiveness. Together, they may act as a biomarker for hepatocarcinoma (HCC) or liver cancer.
