New understanding of DNA repair may pave way to cancer treatments

...xpected to disturb the otherwise conserved balance between its role in gene regulation and the DNA damage response. We need to find out which of the two functions is more dominant under these circumstances in order to devise ways to regain the proper balance," he said. The Ronai lab's work on ATF2 was start...

Cerebral navigation: How do nerve fibers know what direction to grow in?

...o engulf the ephrin-Eph complex, breaking the bond between the two and repelling the axon, causing it to turn away. When mice were genetically modified to lack Vav2 and the related Vav3, thereby eliminating this repellent signal, the mice had abnormal axon projections and defects in neural circuitry formatio...

Live vaccines more effective against horse herpes virus

...th. The virus is spread mainly by intimate contact between horses. Once infected, a horse carries the virus for the rest of its life in a "latent" (dormant) state. The same symptoms from the initial infection can be reactivated by stress later in life. Osterrieder will present his new findings on vaccine ef...

"Both serum and saliva exhibited unique genetic profiles," said Wong. "The risk model yielded a predictive power of 95 percent by using only the salivary transcri...

Mouse gene shows new mechanism behind cardiac infarction in man

At long last, scientists figure out how plants grow

"Nihal was able to get that to work in a test tube, but the interaction would only occur if he added auxin to the solution." Auxin may stick around awhile, but it is eventually broken down by natural cell proce...

One gene flags virus-infected cells for destruction, the other gene allows our Natural Killers cells to recognize and terminate them. "This is a new concept in natural disease resistance," notes Dr. Vidal. "Our research suggests there are ...

"Everyone knows that the salt is not good for the environment, but salting roads is a huge safety issue in a part of the country that gets 10 to 12 feet of snow every winter." Silver's research does show a larg...
