- A study by the MUHC and McGill University opens a new door to understanding cancer
08-09-2007 · EurekAlert!
An in-depth understanding of the mechanisms that trigger cancer cell growth is vital to the development of more targeted treatments for the disease. An article published in the Aug. 3 issue of Molecular Cell provides a key to these mechanisms that may prove crucial in the future. The paper is co-authored by Dr. Morag Park, director of the MUHC Molecular Oncology Group, and Dr. Kalle Gehring, head of the Nuclear Magnetic Resonance Laboratory of the McGill University biochemistry department.

- OHSU Cancer Institute research discovery opens new window to understanding chronic myeloid leukemia
12-09-2007 · EurekAlert!
Oregon Health & Science University Cancer Institute researchers have opened a new window into the roots of chronic myeloid leukemia (CML). "We are looking under the surface of CML to understand better where the cancer is coming from. We have discovered abnormal cells in the early stem cell population in some CML patients, which don't belong to the CML clone. These are abnormal cells that are not part of the CML clone," said Thomas Bumm, M.D., OHSU Cancer Institute member.

- Researchers find 'zip code' spurs cargo transport in neurons
10-24-2006 · EurekAlert!
Getting molecular cargo from the cell body to the synapse of nerve cells is crucial for learning and memory, even for survival of the cell itself. New research conducted at Brown University and the Marine Biological Laboratory in Woods Hole, Mass., shows that a single peptide can load and direct this biological material. This peptide "ZIP Code" comes from amyloid precursor protein, the principal player in the development of Alzheimer's disease.

- Weizmann Institute scientists discover a key player in embryonic muscle development
04-11-2007 · EurekAlert!
In the final stage of muscle fiber development, the cell membranes of attached myoblasts open up and fuse together, forming one large, unified cell. It is known how myoblasts identify other myoblasts and cling together, but the way that the cell membranes fuse into one has remained a mystery. Scientists have now discovered that a protein called WIP plays a key role in muscle cell fusion.

- Tsunami-recording in the deep sea
11-19-2007 · EurekAlert!
In order to extend alert times and avoid false alarms, a new seafloor pressure recording system has been designed to detect tsunamis shortly after their development in the open ocean. The project is directed by scientists of the working group 'Marine Observation Systems' at the Alfred Wegener Institute for Polar and Marine Research, part of the Helmholtz Association.

- UGA scientists unravel 'molecular inch-worm' structure of walking-pneumonia bacterium
10-23-2006 · EurekAlert!
Researchers at the University of Georgia, using glow-in-the-dark proteins and microcinematography, have helped unravel the development and function of a complex organelle in the bacterium that causes "walking pneumonia."The researchers have described in new, precise detail the unique cell extension that forms on one end of the bacterium Mycoplasma pneumoniae. This structure, called a "terminal organelle," performs several tasks for this pervasive bacterium and even acts as a "molecular inch-worm," helping the microorganism move.

- Modern brains have an ancient core
06-29-2007 · EurekAlert!
Researchers from the European Molecular Biology Laboratory now reveal that the hypothalamus and its hormones are not purely vertebrate inventions, but have their evolutionary roots in marine, worm-like ancestors. In this week's issue of the journal Cell they report that hormone-secreting brain centres are much older than expected and likely evolved from multifunctional cells of the last common ancestor of vertebrates, flies and worms.
