Transduction without tip links in cochlear hair cells is mediated by ion channels with permeation properties distinct from those of the mechano-electrical transducer channel.

Walter Marcotti et al.

The Journal of neuroscience : the official journal of the Society for Neuroscience, 34(16), 5505-5514 (2014-04-18)

Tip links between adjacent stereocilia are believed to gate mechano-electrical transducer (MET) channels and mediate the electrical responses of sensory hair cells. We found that mouse auditory hair cells that lack tip links due to genetic mutations or exposure to

Depression and synaptic zinc regulation in Alzheimer disease, dementia with lewy bodies, and Parkinson disease dementia.

David R Whitfield et al.

The American journal of geriatric psychiatry : official journal of the American Association for Geriatric Psychiatry, 23(2), 141-148 (2014-06-24)

Depression is a common symptom in dementia with Lewy bodies (DLB), Parkinson disease dementia (PDD), and Alzheimer disease (AD), yet its molecular basis remains unclear and current antidepressants do not appear to be effective. Cerebral zinc has been implicated in

Ocean plankton. Patterns and ecological drivers of ocean viral communities.

Jennifer R Brum et al.

Science (New York, N.Y.), 348(6237), 1261498-1261498 (2015-05-23)

Viruses influence ecosystems by modulating microbial population size, diversity, metabolic outputs, and gene flow. Here, we use quantitative double-stranded DNA (dsDNA) viral-fraction metagenomes (viromes) and whole viral community morphological data sets from 43 Tara Oceans expedition samples to assess viral
