Lymphatic vessel and lymph node function are restored with growth factor treatment

The frequent spread of certain cancers to lymph nodes often necessitates surgery or radiation therapy that damages the lymphatic system and can cause lymphedema, a condition of localized fluid retention that often increases susceptibility to infections.

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.

Adding water-soluble polymer to anti-cancer drug helps reach brain tumors

Bioengineers at Yale and Cornell have created a modified chemotherapy that more effectively reaches and remains at the site of brain tumors — by adding a water-soluble polymer to the anti-cancer drug, according to a report in the November-December issue of Bioconjugate Chemistry.
