Acute one-hour treatment of Pik3ca mutant mice with a novel anti-epilepsy drug suppresses seizures despite continued developmental brain dysmorphology, promising a new therapeutic strategy for patients with intractable pediatric epilepsy.
An innovative, fully computerized approach for measuring spontaneous social behavior in mice closely follows murine ethology, eliminates crucial sources of data irreproducibility and enables fast, inexpensive assessment of sociability in group-housed subjects.
A mouse model reveals that a p53 SNP impacts longevity via modulating the balance of cancer risk and the self-renewal function of stem/progenitor cells, which supports a role of p53 in regulation of longevity.
Impaired GABAergic and glutamatergic synaptic function and loss of interneurons in the amygdala, hippocampus, and cerebellum cause characteristic disease symptoms in a mouse model juvenile neuronal ceroid lipofuscinosis.
In mouse models of Huntington's disease, the subthalamic nucleus, which suppresses movements, also exhibits impaired glutamate homeostasis, NMDA receptor-dependent mitochondrial oxidant stress, firing disruption, and 30% neuronal loss.
Cardiac-specific overexpression of a recently discovered micropeptide, DWORF, enhances calcium cycling and contractility in the heart and rescues the heart failure phenotype of a genetic mouse model of dilated cardiomyopathy.
