St. Jude projects 90 percent cure rate for ALL

...nt improvements promise to continually improve the survival rate of ALL, Evans said. For example, new drugs directed against the proteins made by genes linked to ALL will add to the options for treating this disease. "Multiple breakthroughs at St. Jude and elsewhere have transformed ALL from a virtual death ...

'Genetic network' guards against lethal DNA damage

...6,000 genes, of which about 1,000 are essential to survival and 5,000 are not, Boeke said. Specifically, 1,000 of the 5,000 non-essential genes are important enough so that the yeast grows slowly if any one of them is absent. And any of the 4,000 other genes can be deleted from the cell without interfering wi...

Losing sleep undoes the rejuvenating effects new learning has on the brain

Plant-derived vaccines safeguard against deadly plague

...gs vaccinated with V antigen alone had the highest survival rates. "This study provided validation of our plant expression system, that it can produce the bacterial antigens in a native form that will allow for an appropriate immune response against a bacterial pathogen." Mason. Critical to the success o...

New test to detect rare proteins in blood

... a lower response rate to chemotherapy and shorter survival time after relapse. The Greene lab developed mouse models that carry cancer cells overexpressing Her2/neu. When these cells are implanted into animals they form tumors exactly like breast tumors in humans. Using ELISA, the researchers could not det...

Study: Paramedics save more lives when they don't follow the rules

Hopkins researchers discover genetic switch that turns off an oxygen-poor cell's combustion engine

... a target for cancer drugs because a cancer cell's survival depends on it to convert glucose to lactic acid through glycolysis even in the presence of ample oxygen. Disruption of the switch by a drug may cause cancer cells to pollute themselves with toxic oxygen molecules and undergo apoptosis or cell death. ...

Scientists discover new genetic subtypes of common blood cancer

Molecular force field helps cancer cells defend against attack

...l cancer therapy." "FAK plays a major role in the survival of tumor cells in their normal attached state, and, when over-expressed or hyperactivated, it opens a molecular gate that allows tumor cells to detach and metastasize," Frisch said. "The Cance lab's new observations on the VEGFR3-FAK interaction are ...

Don't hold your breath: Carp can manage without oxygen for months

...n where evolution has solved the problem of anoxic survival millions of years ago, something that medical science has struggled with for decades with limited success", says Professor Göran Nilsson who will be presenting his latest results at the Annual Meeting for the Society for Experimental Biology on Frida...

Enzyme crystal structure reveals 'unexpected' genome repair functions

...each day, making NER critically important for cell survival and protection against mutations. NER is a critical defense mechanism that removes DNA lesions caused by the mutating effects of sunlight (ultraviolet light) and toxic chemicals. In addition, NER is critical to the success of the anticancer drug ci...

Study may help slay 'Yellow Monster'

...pi may not get cancer to a greater extent, but the survival rate is lower than the general population." Stearns said the lower survival rate might be more the result of limited access to care or cultural boundaries that may prevent peop...

Study finds 60 new genes controlled by DNA snippet

...e during the copying process. Some mutations bring survival advantages and others cause disease. Most known genetic diseases identified to date result from a mutation within a gene that directs protein construction, but that may soon change. "We believe more and more disease-causing mutations will be found...

...y other similar objects that are critical to human survival and communication." Riesenhuber hopes that integrative research of this kind will help scientists better understand the neural bases of object recognition deficits in mental disorders, such as autism, dyslexia or schizophrenia. People with autism, f...

Mutation in blood stem cells provides clues to cancer development

Working with specific inhibitors developed by local pharmaceutical companies, the UCSD and Stanford researchers plan to conduct clinical trials in the near fut...

Radiotherapy advance points way to noninvasive brain cancer treatment

...years. Currently, the only treatments that stretch survival limits are exceptionally invasive surgeries to remove the tumor and radiation treatment with the maximum tolerated dose - all of which leads to a painfully low quality of life. Because of this, researchers are racing to find better therapies to stop ...

'Prosthetic' retinal cells let blind mice see light

...geneous as to the time course of the degeneration, survival cell types, and, possibly, their functional state. Therefore, further studies are required to evaluate what types of retinal degenerative diseases and/or what disease stages are suitable for this potential treatment strategy," they wrote. However, n...
