Nature publication reports key links between mechanisms of aging and metabolic disorders

..., and 4) INDY ('I'm not dead yet'), a cell surface transporter known to increase lifespan in flies when mutated. Dr. Kopchick stated, "The article by DiStefano et al. will stimulate a paradigm shift in our thinking about aging and age-related disorders. As pointed out by the authors, we are beginning to recogni...

Study identifies fat-secreted protein linked to insulin resistance

...had focused on understanding the role of a glucose transporter protein called GLUT4 in the development of insulin resistance. Knowing that downregulation of GLUT4 expression in fat tissue is an almost universal feature of insulin-resistant states (including obesity, type 2 diabetes and the metabolic syndrome), p...

Mayo Clinic researchers invent 'hitchhiking' viruses as cancer drug delivery system

...r showed that once it reached the tumor, the viral transporter successfully transferred a gene to both mouse and human tumor cells that then infected the cells. This proved that the concept works. Collaboration and Support In addition to Dr. Vile, the Mayo Clinic research team included Caroline Cole, Ph.D.; Ji...

Drug aimed at Huntington's eases chorea, the disease's hallmark feature

...e inhibits a molecule known as vesicular monoamine transporter 2 (VMAT2), an action that ultimately blocks the release of dopamine. This is not a wonder drug for Huntingtons. It doesnt address the psychiatric or cognitive problems, for instance. But there are some patients for whom chorea is clearly a devastatin...

This mutation --- a single nucleotide change in the promoter region of the EAAT2 gene -- was equally prevalent in healthy individuals and stroke patients. But among stroke patients, those with the mutated allele had higher plasma leve...

...ch he and his colleagues established as the single transporter responsible for the vast majority (~70%) of salivary fluid secretion. The body of work generated by his research group includes kinetic, regulatory, and structural studies. Thanks to their efforts, we know how important NKCC1 is to salivation, how to...

Johns Hopkins lab scientists tame overactive CF protein

... 97 (valosin containing protein), kills a chloride transporter in the cells of the vast majority of CF patients, but quieting the protein restores the cells' ability to transport chloride in and out, researchers found. The inability to transport chloride is the hallmark of CF that causes dangerous buildup of thi...

"Antidepressants, especially the SSRIs, which increase the availability of serotonin, may actually be working by shifting the availability of 5-HT1A autoreceptors and, as a consequence, modulating the reactiv...
