Wisconsin scientists grow critical nerve cells
...ovide critical guideposts for scientists trying to repair damaged or diseased nervous systems. Motor neurons transmit messages from the brain and spinal cord, dictating almost every movement in the body from the wiggling of a toe to the rolling of an eyeball. The new development could one day help victims...Deficient DNA Repair Capacity Associated With Increased Risk Of Breast Cancer

"It's a steeper challenge that would require additional technology such as light-activated gene therapy (LAGT) to site-specifically target the genes to the edge of the damaged cartilage during arthroscopic surgery, but we're looking to use t...Molecular machine may lead to new drugs to combat human diseases
...targeted trans-splicing technique has been used to repair hemoglobin infected with sickle cell anemia. The new structure provides scientists with tools to expand on ways to harness this molecular machine, Golden said. The other researchers on this study were Hajeong Kim, graduate student, and Elaine Chase,...Vital step in cellular migration described by UCSD medical researchers
...ent of cells within the body during growth, tissue repair and the body's immune response to invading pathogens, has been demonstrated by researchers in the University of California, San Diego (UCSD) School of Medicine.

...d with the regulation of DNA itself, including the repair of DNA damage. "These new steps indicate there is more to RNAi than RNA destruction," says Kim. "And the connection to DNA damage pathways, which was totally unexpected, suggests a potential connection between RNAi and the control of cell division in...Gene Therapy For Parkinson's Disease Moves Forward In Animals

They have already visualized the dots' journey from the area surrounding the nucleus to inside the nucleus, a feat that opens the door for real-time observations of nuclear trafficking mechanisms. They also hope to target other...DNA Recombination and Repair—A New Twist to RecA Function
