Transgenic animals produced using cultured sperm

...erapeutic options." Past efforts to genetically modify sperm cells in animals prior to fertilization have been stymied by the failure of these cells to mature under in vitro growth conditions. Drawing upon the cell culture expertise of Noriyoshi Sakai, Ph.D., and Kayoko Kurita, of Fukui Prefectural Unive...

Pew report finds GM insects may offer benefits, but clear regulatory oversight is lacking

... Scientists are currently working to genetically modify insects to address important economic and human health concerns. If successful, GM insects could dramatically improve public health and enhance agricultural production. Examples include: Mosquitoes incapable of transmitting malaria, which is...

Transgenic mosquitoes are less fertile than their counterparts in nature

... who leads a major research program to genetically modify mosquitoes to combat mosquito-borne disease, was not surprised that there was a fitness cost associated with transgenesis, but was surprised with the magnitude of it. "Once we determine the genetic basis of these fitness costs it should be possible t...

New roles for protein modifications in cell migration

...hough Golgi NDPases such as MIG-23 can conceivably modify a number of other secreted proteins, the Nishiwaki study indicates that the effects of the NDPase dysfunction are especially prominent in the abnormal glycosylation and function of an ADAM family protease, suggesting that glycosylation may play a mor...

Symbiotic fungi promote invasion into diverse plant communities (Rudgers et al.)

...ay investigated whether these endophytic fungi can modify how diverse communities resist invasion. Their model predicts that endophyte-infection of a grass invader will weaken the ability of diverse communities to resist invasion and reduce the correlation between diversity and community productivity. Their...

Emory scientists use enzymes to enhance regeneration of damaged peripheral nerves in mice

...s to regenerate, the Emory scientists attempted to modify this inhibitory environment following peripheral nerve injury in mice. They treated the peripheral portion of severed nerves with each of three enzymes that degrade specific types of proteoglycans. During the first two weeks after the injury, axon...

Salk news: Gene chips and crop yield

...hnology may lead to the development of new ways to modify plants to grow faster, produce more food and resist disease. The study, which appears in the Oct. 31 issue of Science, led by Joe Ecker, Salk professor of plant biology, and Athanasios Theologis, adjunct professor at UC Berkeley and senior scientist ...

US develops lethal new viruses

...sts might be more tempted to use the same trick to modify a pox virus that infects humans. Such a disease, like anthrax, would infect only those directly exposed to it. It would not spread around the world and rebound on the attackers. But there is no guarantee that other pox viruses modified in a similar w...

Research finds tumor preventive qualities, damage reversal, in green tea
