Researchers find possible link between autism and nuclear receptor protein LXRβ

Research by University of Houston scientists discovered a possible link between nuclear receptor protein LXRβ (Liver X receptor Beta) and autism spectrum disorder. They found that nuclear receptor LXRβ deletion causes poor development of dentate gyrus, a part of brain’s hippocampus. The dentate gyrus, or DG, is responsible for emotion and memory and is known …

Large synthetic nanoparticles mimic biomolecules

Chemists at Carnegie Mellon University have demonstrated that synthetic nanoparticles can achieve the same level of structural complexity, hierarchy and accuracy as their natural counterparts biomolecules. The study, published in Science, also reveals the atomic-level mechanisms behind nanoparticle self-assembly. The structure of the largest gold nanoparticle to-date, Au246(SR)80, was resolved using x-ray crystallography. Credit: Rongchao …

Protein Wnt5a is important in sustaining adult neuron structure in mice hippocampus

Humans and other vertebrates depend on a portion of the brain called the hippocampus for learning, memory and their sense of location. Nerve cell structures in the adult hippocampus are sustained by factors whose identities have remained largely mysterious so far. Now, research led by a Johns Hopkins University biologist Dr. Kuruvilla sheds light on …

Research in mice shows molecular mechanism underlying Oxycodone addiction

RGS9-2, a key signaling protein in the brain known to play a critical role in the development of addiction-related behaviors, acts as a positive modulator of oxycodone reward in both pain-free and chronic pain states, according to a study conducted at the Icahn School of Medicine at Mount Sinai and published in the journal Neuropsychopharmacology. …

Computer models to analyze Huntington disease pathology

Rice University scientists have uncovered new details about how a repeating nucleotide sequence in the gene for a mutant protein may trigger Huntington’s and other neurological diseases. Researchers used computer models to analyze proteins suspected of misfolding and forming plaques in the brains of patients with neurological diseases. Their simulations confirmed experimental results by other …
