Elusive HIV shape change revealed; Key clue to how virus infects cells

Structural biologists at Children's Hospital Boston and Harvard Medical School have shown how a key part of the human immunodeficiency virus (HIV) changes shape, triggering other changes that allow the AIDS virus to enter and infect cells. Their findings, published in the Feb. 24 issue of the journal Nature, offer clues that will help guide vaccine and treatment approaches. Researchers led...

Iron Deficiency Sparks Dramatic Changes In Gene Expression

Researchers at Duke University Medical Centerhave demonstrated for the first time what happens inside a cell when itis deprived of the essential nutrient iron. Iron is found abundantly inred meats, shellfish dried fruits, whole grains, spinach, seeds andother foods.Their study in yeast cells demonstrated that iron-starved cellspreserve the little iron they possess by shutting down the major...

New Study from Affymetrix Laboratories Points to Changing View of How Genome Works

Scientists at Affymetrix, Inc. (Nasdaq: AFFX) reported today in Science magazine online that they have completed a high-resolution scan of structure and function for nearly 30 percent of the human genome sequence. In collaboration with the National Cancer Institute, the research team used high-density GeneChip(R) microarrays to study every fifth base, on average, of 10 human chromosomes; they fou...

Researchers trace evolution to relatively simple genetic changes

In a stunning example of evolution at work, scientists have now found that changes in a single gene can produce major changes in the skeletal armor of fish living in the wild. "Our motivation is to try to understa...

Plants defy Mendel's inheritance laws, may prompt textbook changes

Contrary to inheritance laws the scientific world has accepted for more than 100 years, some plants revert to normal traits carried by their grandparents, bypassing genetic abnormalities carried by both parents. These mutant parent plants apparently have hidden templates containing genetic information from the preceding generation that can be transferred to their offspring, even though the...
