Scientists at Johns Hopkins have deciphered the genetic code for a type of pancreatic cancer, called neuroendocrine or islet cell tumors. The work, described online in the Jan. 20 issue of Science Express, shows that patients whose tumors have certa…
A University of Manchester scientist has revealed the mechanism that binds skin cells tightly together, which he believes will lead to new treatments for painful and debilitating skin diseases and also lethal heart defects.
Professor David Garrod,…
The difficult task of sorting and counting prized stem cells and their cancer-causing cousins has long frustrated scientists looking for new ways to help people who have progressive diseases.
But in a development likely to delight math teachers, U…
University of Rochester Medical Center orthopaedic scientists are a step closer to developing a vaccine to prevent life-threatening methicillin-resistant staphylococcus aureus (MRSA) infections following bone and joint surgery.
Other MRSA vaccine …
GALVESTON, Texas — When most people in the developed world think of measles, what comes to mind is only a dim memory of a vaccination at a pediatrician’s office. But while childhood vaccination has virtually eliminated measles from North America …
BETHESDA, Md., Jan. 11, 2011 — An international team of researchers is reporting that it has uncovered new information about human papillomavirus that one day may aid in the development of drugs to eliminate the cervical-cancer-causing infecti…
Scientists have identified the type of cell that is at the origin of brain tumors known as oligodendrogliomas, which are a type of glioma — a category that defines the most common type of malignant brain tumor.
In a paper published in the Decemb…
Tampa, Fla. (Dec. 23, 2010) — Two studies appearing in the current issue
of Cell Transplantation 19(10) discuss stem cells derived from adipose (fat) cells and their potential use in plastic surgery and tissue reconstruction. The studies are now…
PHILADELPHIA — Overexpression or hyperactivation of ErbB cell-surface receptors drives the growth of many breast cancers. Drugs, like Herceptin, that block the receptors’ signals halt tumor progression in some patients. However, not all pati…
PITTSBURGH — An international team of researchers led by Carnegie Mellon University’s Manojkumar Puthenveedu has discovered the mechanism by which signaling receptors recycle, a critical piece in understanding signaling receptor function. Wri…
A virus previously thought to be associated with chronic fatigue syndrome is not the cause of the disease, a detailed study has shown. The research shows that cell samples used in previous research were contaminated with the virus identified as XMRV…
AURORA, Colo. (Dec. 14, 2010) — A combination therapy for treating cancer discovered at the University of Colorado Cancer Center showed improved survival rates in patients with advanced non-small cell lung cancer (NSCLC), according to results from…
For patients with glioma, the most common primary brain tumor, new findings may explain why current therapies fail to eradicate the cancer. A UCSF-led team of scientists has identified for the first time that progenitor rather than neural stem cell…
Like an overprotective parent on the first day of school, a targeting factor sometimes needs a little push to let go of its cargo. Scientists at the European Molecular Biology Laboratory (EMBL) in Grenoble, France, have visualised one such hand-…
CINCINNATI — For the first time, scientists have created functioning human intestinal tissue in the laboratory from pluripotent stem cells.
In a study posted online Dec. 12 by Nature, scientists from Cincinnati Children’s Hospital Medical Center…
Scientists have discovered how a network of repair proteins enables bacteria to prioritise the repair of the most heavily used regions of the DNA molecules that carry the instructions necessary for living cells to function.
The research, carried o…
Johns Hopkins scientists have identified a previously unrecognized step in the activation of infection-fighting white blood cells, the main immunity troops in the body’s war on bacteria, viruses and foreign proteins.
“It’s as if we knew many of …
Athens, Ga. — Researchers at the University of Georgia have discovered a central switch that controls whether cells move or remain stationary. The misregulation of this switch may play a role in the increased movement of tumor cells and in the agg…
