Peptide loaded gold nanospheres find, penetrate, then fuel burning of melanoma

Hollow gold nanospheres equipped with a targeting peptide find melanoma cells, penetrate them deeply, and then cook the tumor when bathed with near-infrared light, a research team led by scientists at The University of Texas M. D. Anderson Cancer Center reported in the Feb. 1 issue of Clinical Cancer Research.

Stat3 signaling tips the balance of immunity in favor of cancer

New research reveals how a cancer-associated protein enables tumor cells to evade the immune system by both suppressing antitumor influences and promoting tumor-enhancing conditions, in essence turning the immune system to the dark side of the force.

Shortened gene region linked to breast cancer

Reza Zarnegar and colleagues, at the University of Pittsburgh, Pittsburgh, have determined that genetic variation in a piece of DNA that regulates activity of the HGF gene might be a useful marker to identify individuals with an increased risk of developing breast cancer.
