Genomic Analysis Uncovers New Targets for HIV Vaccine

... knowledge of why patients differ in how well they can control the virus that causes AIDS. These findings represent only the first of what investigators said will be a series of future genome-wide studies to pinpoint additional targets for HIV vaccines. In the new analysis, patients with specific gene v...

Birds can tune in to classics like Vivaldi’s “Concert in D Major,” Miles Davis’s “Blue and Green,” and Led Zepplin’s “Kasmir.” They may also hear songs about the winged life like “Marching Jaybird” by Etta Baker, “Birds” by Neil Young, and “I’m a Cuckoo” by Be...

Common cancer gene sends death order to tiny killer

...a great deal of evidence that microRNAs themselves can act to either promote cancer or to stop cancer spread." To test their idea, the team first chemically damaged the DNA of two sets of colon cancer cells, one missing p53 and the other containing healthy p53. They then looked for any of the 500 know...

Researchers discover inherited mutation for leukemia

...lence unneeded genes. But abnormal DNA methylation can turn off genes that control cell growth, and that lead to tumor growth. "Our findings identify for the first time a gene that appears to be associated with hereditary CLL," says coauthor John C. Byrd, professor of internal medicine and a CLL spec...

Agent slows aging in mice

Miller reports early results from a mouse study his lab and two others are conducting for the National Instit...

Enzyme delivered in smaller package protects cells from radiation damage

...ished radioprotection to cells. "Because we now can deliver MnSOD in this very small vector, we will be able to get this radioprotective enzyme more efficiently into all of the cells of the body and give patients receiving total body radiation for systemic cancers better long-term outcomes. This also ...

Brain inflammation may be friend, not foe, for Alzheimer's patients

...It’s the first use of an organism where scientists can boost IL-1beta in select areas and then watch what happens as the process unfolds. The team expected to see the telltale clumps of material known as amyloid plaques, made up of the peptide amyloid beta, worsen. Instead, to the team’s surprise, the...

Pregnant mom's exposure to flu vaccine kick-starts fetal immune system

Some researchers have hypothesized that the fetus can be exposed to and mount an immune response against allergens to which the mother has been exposed, and this may have an effect on the development of allergic sensitivity (e.g. eczema and asthma) later in an infant’s life. However this hypothesis has ...
