New role for miRNA in leukemia discovered

Scientists here have found that mini-molecules called micro-RNA may play a critical role in the progression of chronic myeloid leukemia (CML) from its more treatable chronic phase to a life-threatening phase, called blast crisis.

New understanding of biological effects of alcohol on genes within cells

Alcohol triggers the activation of a variety of genes that can influence the health and activity of brain cells, and new research from Weill Cornell Medical College in New York City sheds light on how that process occurs.

Chikungunya in La Reunion - new findings

Researchers have discovered the key to how a mysterious mosquito-borne viral outbreak swept over the Indian Ocean island of La Reunion in 2005 and 2006, infecting about 266,000 people and causing at least 260 deaths — the first fatalities to be reported in connection with the virus, known as chikungunya.

Improprieties revealed at California Stem Cell Institute

More apparent conflict of interest violations in applications for research grants in California's $6 billion stem cell program were revealed and the Foundation for Taxpayer and Consumer Rights (FTCR) called for all the tainted applications to be rejected.

Mechanism for regulation of growth and differentiation of adult muscle stem cells is revealed

During muscle regeneration, which is a natural response to injury and disease, environmental cues cause adult muscle stem cells (satellite cells) to shift from dormancy to actively building new muscle tissue.

More good Gleevec news

Gleevec, the targeted cancer pill that has saved more than 100,000 lives, now is saving more children with a dire leukemia, as well as preventing disease progression with long term use in adults with chronic myeloid leukemia.

Missing brain protein may be one of the culprits behind autism and other brain disorders

The protein helps synapses develop. Synapses--through which neurons communicate with one other-underlie our ability to learn and remember. Now Li-Huei Tsai, Picower Professor of Neuroscience at MIT, has uncovered an enzyme that is key to that protein's activity.

Implanting embryonic cardiac cells prevents arrhythmias

When researchers at Cornell, the University of Bonn and the University of Pittsburgh transplanted living embryonic heart cells into cardiac tissue of mice that had suffered heart attacks, the mice became resistant to cardiac arrhythmias, thereby avoiding one of the most dangerous and fatal consequences of heart attacks.
