SALT LAKE CITY, November 22, 2010 — Researchers from Huntsman Cancer Institute (HCI) at the University of Utah report that they have identified a previously undiscovered trigger mechanism for a quality control checkpoint at the very end of the cel…
CHICAGO — Natural killer cells are major weapons in the body’s immune system. They keep the body healthy by knocking off tumors and cells infected with viruses, bombarding them with tiny lethal pellets. But natural killer cells are powerless agai…
By tracking the fate of a group of immature cells that persist in the adult brain and spinal cord, Johns Hopkins researchers discovered in mice that these cells undergo dramatic changes in ALS, also known as Lou Gehrig’s disease.
A study reported N…
HOUSTON – Red-blood-cell-boosting drugs used to treat anemia may undermine breast cancer treatment with Herceptin, a targeted therapy that blocks the cancer-promoting HER2 protein, researchers from The University of Texas MD Anderson Cancer…
Fear arises in the almond-shaped brain structure known as the amygdala. It is the amygdala which processes the strange noise, shadowy figure or scary face and not only triggers palpitations or nausea but can also cause us to flee or freeze. That muc…
LOS ANGELES (Nov. 4, 2010) — Nine years ago, scientists at Cedars-Sinai’s Maxine Dunitz Neurosurgical Institute detected a subtle shift occurring in the molecular makeup of the most aggressive type of brain tumors, glioblastoma multiforme. With fu…
BOSTON (3:00 p.m. ET, November 1, 2010) — A class of compounds that interferes with cell signaling pathways may provide a new approach to cancer treatment, according to a study published online this week in the Proceedings of the National Academy…
If there is one thing that recent advances in genomics have revealed, it is that our genes are interrelated, “chattering” to each other across separate chromosomes and vast stretches of DNA. According to researchers at The Wistar Institute, many…
Researchers from Mount Sinai School of Medicine have identified a mechanism controlling the function of a protein that binds to DNA during embryonic development and may function to prevent abnormal tumor growth. When the protein, TCF3, is modified b…
BOSTON — The discovery that a protein called Rictor plays a key role in destroying a close cousin of the AKT oncogene could provide scientists with a new molecular target for treating certain cancers, including breast cancer. Described in the Sept…
Montreal, October 28, 2010 — A team of scientists at the Institut de recherches cliniques de Montréal (IRCM) led by Dr. Jean-François Côté, Director of the Cytoskeletal Organization and Cell Migration research unit, identified a novel molecula…
PHILADELPHIA – A recently identified immune cell that directs other cells to fight infection plays a critical role in regulating the immune system in both health and disease. Researchers from the University of Pennsylvania School of Medicine h…
