Natural glucose byproduct may prevent brain damage and cognitive impairment after diabetic coma

...tivation of an enzyme called PARP-1, which in turn prevents neurons from metabolizing glucose into pyruvate, which is used to power cells. Deprived of pyruvate, the neurons starve and die. In the current study, Swanson and Suh discovered they could circumvent the action of PARP-1 and keep neurons alive by adm...

Keeping cancer in check

...activated protein kinase (AMPK) is turned on, it prevents cells from replicating. It acts as a sensor to detect energy levels in a cell. When the cell experiences energy-limiting conditions, which is typified by low glucose, it uses more energy than it produces and enters into an energy-deficit state. In es...

Combating antibiotic resistance

...hers also demonstrated that blocking LexA cleavage prevents mutation and results in bacteria that are unable to evolve antibiotic resistance. Thus, developing novel therapeutic agents that target LexA or the associated SOS pathway may prove a promising strategy for controlling the spread of the superbugs....

Innovative coating could give medical implants a longer life

...rthwestern, which sticks securely to a surface and prevents cell and protein buildup, works for a long period of time. In laboratory studies, the new coating provided effective fouling resistance for more than five months, which Phillip B. Messersmith, associate professor of biomedical engineering in the McCo...

"Every year the grant will also support several pilot projects that are intriguing, but still need basic data," said Cotman, who is also a professor of neurology and professor of ...

New understanding of DNA repair may pave way to cancer treatments

... role in DNA repair, an intracellular process that prevents formation of genetic mutations, including those that lead to cancer. "This is the first time we've seen a protein which has been implicated in gene regulation possess an independent function--in DNA repair--while both functions are uncoupled from o...

Technique may allow cancer patients to freeze eggs, preserving fertility before starting treatment

... the egg is thawed, ice crystals cause damage that prevents the egg from being fertilized. U-M researchers looked beyond traditional techniques to a method of freezing cells called vitrification. This cryopreservation technique allows the eggs to be cooled fast enough that the transformation from liquid to so...

The frozen eggs can then be safely stored in the Cryoleaf until it is ready for use, at which point it is carefully thawed, then fertilized. To date, 15 patients at the McGill Rep...

Virus uses tiny RNA to evade the immune system

...h larger messenger RNAs (mRNAs). That interference prevents mRNAs from making proteins. Scientists do not know which genes are hushed by the microRNAs in people, but the new study bolsters growing evidence that the little molecules can play important roles not only in normal human cells but in infected cells ...

Suppressing growth hormone in early adulthood may prevent cancer

... blood-borne factor that increases cell growth and prevents cell death and has been proposed to be a factor in the initiation of cancer. "Elevated IGF-1 levels in pre-menopausal women have been demonstrated to be a risk factor for breast cancer as well as numerous other cancers," said Sonntag, professor of p...

Cancer research finds targets for new cholesterol-lowering therapies

... removal, combining a statin with a treatment that prevents Fbw7/SREBP interaction would likely be of more benefit to some patients than statins alone." Dr. Ericsson said that the team also found that the Fbw7/SREBP interaction may also be connected to diabetes, as insulin signaling inhibited Fbw7's ability ...

Once given 'no respect,' cells' tiny RNAS take driver's seat

...rence -- a biological phenomenon that specifically prevents RNA from being used to make proteins. Accompanying the Hopkins paper are two reports looking specifically at microRNAs in cancer -- one in humans, one in mice. One report shows that human tumors' microRNA "fingerprints" -- patterns showing which of t...

Cancer drug could aid premature labour

...e womb to produce a muscle relaxant, which in turn prevents contractions and keeps the uterus in a relaxed state. It is known that decreases in hCG receptor levels may lead to contractions in the womb and labour. Women whose babies are born prematurely experience an acute drop in the numbers of the CG/LH re...

Tetanus toxin found to have therapeutic properties

This is why the scientists believe the harmless toxin fragment could be more effective than neurotrophins as protection against neurodegenerative disorders such as Parkinson's d...
