MGH researchers find way of regenerating cells key to hearing

...st types of acquired hearing loss. Cells grow and divide through a process called the cell cycle, and many proteins have been indentified as controllers of the different cell cycle phases. Chen's group started by carrying out a comprehensive assessment of which genes are active in the developing mouse ear...

Scientists identify protein critical to melanoma growth

...e it's been previously shown that normal cells can divide and grow normally without CDK2 (other types of CDK molecules apparently can take over the job) "this is good news, because it means there may be little toxicity to a person who would receive a CDK2 inhibitor to treat melanoma," says Fisher, who is al...

Researchers describe how human blood stem cells transform themselves to repair injured animal hearts

...ork by allowing a cell to enter the cell cycle and divide and produce new progeny, but all of this is new and needs to be studied further," Yeh says. Cells that line the many vessels of the heart, however, developed differently in this experiment, Yeh says. More than 97 percent of endothelial cells with a ...

Novel drugs help solve Gleevec resistance

...n multiple signals that tell the cells to grow and divide in an uncontrolled manner leading to overt leukemia. Gleevec binds to the abnormal enzyme (Bcr-Abl) and shuts down its activity, often leading to the death of the leukemia cell. AMN107 is up to 30 times more potent than Gleevec because it was designe...

NCI scientists create model that predicts follicular lymphoma survival

... The two signature model allowed NCI scientists to divide patients into four equal groups with disparate average survival rates of 3.9, 10.8, 11.1, and 13.6 years. For the 75 percent of patients with survival rates 10 years or longer, "watchful waiting is appropriate," Staudt said. "These patients would b...

Chemoprevention backgrounder: Working for a future of cancer chemoprevention

Longterm immune memory cells cells do not develop during chronic viral infections

When the chronic memory CD8 T cells were transferred back into chronically infected mice where they re-encountered antigen, the cells began to recover. The scientists also compared other important qualities of mem...

Researchers shed light on cancer susceptibility using 'supermice'

In addition, the animals developed cancers at a much lower rate upon treatment with different types of carcinogens. The presence of an extra copy of these genes...

Several new techniques show promise for spinal cord repair

Switch of a gene turns cancer cells healthy in mice, Stanford scientists find

'Hedgehog' signal distinguishes lethal from localized prostate cancers

Exactly how the Hedgehog signal is involved in other cancers, including pancreatic and stomach cancers and medulloblastoma, a childh...

Study raises concerns about tablet splitting

This may place them at an ...

Discovery sheds light on how cancer cells grow and divide

...ow normal and cancer cells are organized; how they divide and how they might grow and die -- which is an important part of cancer," says Mark McNiven, Ph.D., the cell biologist who led the Mayo Clinic research team's investigation. "A lot of cancers, you could argue, don't grow faster; they just don't die. ...
