Rat model study reveals printer toner nanoparticles may change both genetic and metabolic profiles, making disease more likely. Read More
Teenage binge drinking is linked to altered gene expression in the brain, specifically the central nucleus of the amygdala. Adolescent rats exposed to alcohol had increased levels of miR-137, resulting in lower expression of proteins essential for healthy neuron growth. During adulthood, these rats displayed higher levels of anxiety and an increased preference for alcohol consumption. Read More
Study identifies a specific gene in rats that relates to physical inactivity. The gene could play a role in human sedentary behaviors. Read More
S1PR3, a receptor found on the surface of brain cells, may play a key role in stress resilience. Veterans with severe PTSD symptoms had lower levels of the S1PR3 protein in their blood than peers without the disorder. Read More
Oxytocin, a hormone commonly associated with love and bonding in humans, causes starfish to turn their stomachs inside-out to feed. The findings provide vital new evidence for the evolutionary role of oxytocin and vasopressin neuropeptides as regulators of feeding in animals. Read More
Stem cell study reveals a genetic defect associated with fragile X syndrome delays the production of neurons during a critical stage of embryonic development. Read More
The phosphatase Prl-1 plays a key role in specifying where to form the highest density of synaptic connections on a neuron. Read More
Functional olfactory receptors have been identified in human taste cells. The findings suggest olfactory receptors play a role in the taste system by interacting with taste receptors on the tongue. The brain, researchers say, combines input from taste, smell and other senses to create a multi-modal sensation of flavor. Read More
Increased kynurenic acid production has been implicated in the pathology of schizophrenia. The findings provide a new target for cell-specific treatments that help reduce the production of kynurenic acid and reduce symptoms of schizophrenia. Read More
Changes in gene expression help researchers identify ALS associated pathways and establish the key drivers of motor neuron degeneration in the disease. Read More
A new study reports chronic nicotine exposure during pregnancy alters the genetics and dopamine neurons of newborns. The findings could help researchers develop a possible cure for nicotine addiction. Read More
Researchers have developed a new approach that uses microRNA in combination with chemotherapy to help treat glioblastoma brain cancer. In preclinical models, the approach increases survival of the deadly brain cancer five fold. Read More
