Mitochondria induce nuclear deformation

In a paper being presented in two American Physiological Society sessions at Experimental Biology 2006, a joint Estonian-French team demonstrated "for the first time that mitochondria are able to induce nuclear deformation, suggesting that mitochondria may mechanically regulate nuclear function."

Enzyme released by cardiac mast cells during heart attack contributes to arrhythmia

In times of cardiac crisis, mast cells in the heart secrete a powerful enzyme, renin, that indirectly triggers dangerous arrhythmias, according to a team of researchers at the Weill Medical College of Cornell University in New York City.

Nicotine and chemotherapy not a good mix

Researchers in the U.S. say that preliminary research has suggested that nicotine can prevent chemotherapy drugs such as taxol from killing lung cancer cells.

Proteomics yields new drug targets for treating cardiogenic shock

When it comes to cell signaling and bioregulation, it's tough to find a more important molecule than nitric oxide (NO). Dysfunction of NO-mediated signaling is thought to be a culprit in lethal cardiovascular conditions such as angina, and septic, cardiogenic and hemorrhagic shock; it may play a role in many other illnesses as well.

Gene key to infection-fighting immune cells identified

Every time the human body encounters a virus, bacteria or other infectious agent, immune cells called B-lymphocytes multiply in lymph nodes and then swing into action to fight off the intruders.

Weill Cornell experts publish review of genetic medicine

In an article published in the April issue of Nature Reviews Genetics, two experts at the Weill Medical College of Cornell University sum up the achievements, challenges and promise of a burgeoning field: genetic medicine.

Special education data provide misleading trends of changing autism prevalence

If statistics compiled by the U.S. Department of Education are to be believed, in 1992 the state of Illinois had only 322 diagnosed cases of autism among school children. In 2003, according to the same statistical source, Illinois had more than 6,000 children diagnosed as autistic.

Expecting enough bird flu vaccine for everyone is a big ask

According to researchers an experimental vaccine produced to offer protection against the H5N1 strain of bird flu presently causing havoc across the world, only appears to work at the very highest doses.

Scientists use bacteria found naturally in soil to produce new antibiotics in the fight against drug-resistant "Super-bugs"

Antibiotic resistance is a major problem worldwide and there is an urgent need for new antibiotics to be developed. Potential new drugs are usually made in the lab which is complicated and time-consuming.

Scientists identify a new gene that causes the spread of cancer

Professor Philip Rudland, Dr Guozheng Wang and Dr Roger Barraclough from the University’s Cancer and Polio Research Fund Laboratories have discovered an additional member of the S100 family of protein genes - S100P - that causes the spread of cancerous cells from an original tumour to other parts of the body.

New evidence questions the simple link between prion proteins and vCJD

While newly published research confirms that under laboratory circumstances prion-protein can be absorbed across the gut, it also shows that this is unlikely to occur in real life.

Weill Cornell researchers identify tumor-suppressor gene important to diffuse large B-cell lymphomas

Inactivation of a "tumor suppressor" gene could be a major cause of a class of blood cancers called diffuse large B-cell lymphomas, reports a team of researchers at the Weill Medical College of Cornell University.

Researchers develop new tool to find gene control regions

Researchers at the McKusick-Nathans Institute of Genetic Medicine at Johns Hopkins have invented a cost-effective and highly efficient way of analyzing what many have termed "junk" DNA and identified regions critical for controlling gene function.

New way of targeting proteins to exosomes - potential for melanoma, Alzheimer's disease

Researchers at the University of Pennsylvania School of Medicine have discovered how a protein called Pmel17 is sorted by pigment cells in the skin and eye to make a fiber matrix that eventually sequesters melanin, the dark pigment found in skin, hair, and eyes.
