Researchers genetically altered mesenchymal stem cells to create new stem cell lines that showed no signs of aging in culture, did not increase tumor production in animal studies and functioned as healthy mesenchymal cells do.
Neuroscience research published in September's Journal of Neuroscience suggests early life stresses may modify the GAD1 gene, which controls the production of GABA. Through their research on rats, researchers were able to note that those who experienced a lack of affection showed an obstruction within the DNA which controls the GAD1 gene. As it is believed that GABA deficits might be apparent within schizophrenic patients, researchers propose that the modification of GAD1 might determine a child's predisposition to mental illness.
Neuroscientists at USC have discovered that carbonated drinks set off the same pain sensors in the nasal cavity as mustard, albeit at a lower intensity. During experimentation, researchers flowed carbonated saline over a dish containing nerve cells taken from the sensory circuits in the nose and mouth. They discovered that the gas activated a specific cell which serve as general pain sensors and expresses the TRPA1 gene.
Researchers have discovered that disabling the RGS14 gene in mice can make them smarter. When the RGS14 gene was disabled within the CA2 region of the hippocampus, researchers found that mice were better able to remember objects they had explored and learn to navigate mazes better than regular mice.
Neuralstem has released a new report detailing positive results for stem cell treatments. Initial findings show that not only do implanted human spinal cord-derived stem cells survive, but also differentiate into neurons in rats brains affected by strokes. This finding could potentially provide new therapies for treating strokes.
New research proposes that academic performance of adolescents is linked to specific dopamine gene variations. Researchers also suggest a correlation exists between the variants of dopaminergic genes a student possesses and performance in specific subject areas.
New research points to a DNA sequence that causes the DUX4 gene to become more active in producing proteins that are toxic to muscle cells, leading to a form of muscular dystrophy.
A large risk genetic marker of schizophrenia has been discovered by scientists. The researchers found that a specific deletion at 3q29, which contains two genes already known to be associated with intellectual disabilities , PAK2 and DLG1, increased the odds of schizophrenia symptoms by nearly 17 times those with no deletion.
Genetics research into the emotional responses of bullying shows that many bullied victims that later experience more emotional problems have genetic similarities.
NT-020, a combination of nutrients, increased neural stem cell proliferation, neurogenesis and helped improve memory in the aging brains of mice.
