Discovery of key acute myeloid leukemia gene

A gene called N-Myc leads a double life in certain white blood cells, helping to trigger a cancer called acute myeloid leukemia (AML) under some conditions while triggering apoptosis, or cell suicide, under other conditions, according to results of a mouse study done by investigators at St. Jude Children's Research Hospital.

Insulin regulates the secretion of the antiaging hormome Klotho

Dr. Carmela Abraham, a professor of biochemistry and medicine at Boston University School of Medicine (BUSM), reports this week in the Proceedings of the National Academy of Sciences new findings on Klotho, an anti-aging gene that is associated with life span extension in rodents and humans.

Link between tooth infection and hair loss

There is a close relationship between infection outbreaks on teeth and the presence of alopecia areata or localized alopecia, a type of hair loss which has an unknown origin.

Fast way of spotting multidrug resistant bacteria could help stop outbreaks in hospitals

A type of bacterium widely found on our skin and in the environment has now become a major threat in hospitals where it can cause serious infections, such as pneumonia in severely ill patients.

Blood-vessel blocker aids cancer-killing virus

Cancer-killing viruses are a promising therapy for incurable brain tumors, but their effectiveness has been limited in part because immune cells rapidly move in and eliminate them.

New disease model for Huntington's

Huntington's disease is a genetic time bomb: Programmed in the genes, it appears at a predictable age in adulthood, causing a progressive decline in mental and neurological function and finally death.

Ozone response greater with increasing BMI

A new study provides the first evidence that people with higher body mass index (BMI) may have a greater response to ozone than leaner people.

Study of Mexican Americans shows that polymorphisms of the CYP2E1 gene enhance susceptibility to alcoholism

Mexican Americans make up 66 percent of the U.S. Hispanic population and, when compared to other ethnic groups, show high rates of heavy drinking and alcohol-related problems.

New genetic evidence supports theory migration from Siberia gave rise to native peoples of North and South America

Did a relatively small number of people from Siberia who trekked across a Bering Strait land bridge some 12,000 years ago give rise to the native peoples of North and South America?

Flip-flopping gene expression can be advantageous

One gene for pea pod color generates green pods while a variant of that gene gives rise to the yellow-pod phenotype, a feature that helped Gregor Mendel, the 19th century Austrian priest and scientist, first describe genetic inheritance.

Problematic drinking and alcohol dependence linked to high number of sex partners

Previous studies have linked heavy drinking and conduct disorder to high-risk sexual behaviors that can, in turn, lead to unintended pregnancies, infection, and damage to reproductive health.
