When the gene was experimentally overexpressed in mice, levels of HDL cholesterol - the "good" cholesterol - dropped to nearly undetectable levels, a condition associated with high cardiovascular disease risk in humans.
Investigators at UT Southwestern Medical Center at Dallas have developed a new way to isolate purified cancer cells - an important advance that will help unravel the mysteries of tumor biology and cancer development.
Harvard Medical School/Howard Hughes Medical Institute researchers have found that the transferrin cycle has a more limited role in iron transport than previously believed. The findings may lead to improved diagnosis and treatment of iron metabolism disorders.

Good insect moms ferociously protect their young by fanning their wings and charging predators--but only when they must pin all their hopes on a single batch of eggs, a University of Delaware scientist reports in the new issue of the journal, Animal Behaviour. Bug moms who lay multiple batches are far more likely to "turn tail and run" from egg-munching predators, says Douglas W. Tallamy.
