HIV drug could treat Alzheimer’s, age-associated disorders

Researchers have found that blocking retrotransposon activity with a generic HIV/AIDS medication significantly reduces age-related inflammation in old mice and senescent human cells, providing hope for treating age-associated disorders.

Male Y chromosomes not ‘genetic wastelands’

Researchers have found a way to sequence a large portion of the Y chromosome in the fruit fly Drosophila melanogaster — the most that the Y chromosome has been assembled in fruit flies. The research provides new insights into the processes that shape the Y chromosome, adding to the evidence that, far from a genetic wasteland, Y chromosomes are highly dynamic and have mechanisms to acquire and maintain genes.

Cancer cells’ plasticity makes them harder to stop

Researchers have created a basic framework of how cancer cells adapt when their attempts to metastasize are blocked by drugs or the body’s immune system. Understanding the cells’ strategies could someday help scientists design therapies that keep them in check.

Brain protein crucial to recovery from stroke

Researchers have identified a brain protein at the root of how the brain recovers from stroke. The finding offers a promising avenue for developing therapies that could work even when given beyond the first few hours after a stroke.

Another early-onset Alzheimer’s gene mutation found, and traced back to Africa

For some of us, they carry the bright blue of our grandfather’s eyes. For others they result in the characteristic cleft chin or the familial tendency toward color blindness. But in some families, the genetic mutations handed down from generation to generation aren’t as benign. And for one family in particular, the mutation results in early-onset Alzheimer’s disease.

How well can H7N9 and H5N8 genetically mix with a seasonal strain?

Emory scientists have been probing the RNA packaging factors that limit reassortment between avian H7N9/H5N8 strains and a well-known strain (H3N2) that has been dominating the last few human flu seasons in the United States. Mix and match still occurred at a low level, particularly with H5N8.

Common virus in early childhood linked to celiac disease in susceptible children

A common intestinal virus, enterovirus, in early childhood may be a trigger for later celiac disease in children at increased genetic risk of the condition, finds a small study.

Genetic variations in a fourth gene linked to elevated leukemia risk in Hispanic children

Progress reported on understanding why Hispanic children are more likely to develop acute lymphoblastic leukemia and to die of the disease.
