The structure of the mechanosensitive channel MscS embedded in a lipid bilayer redefines the nature, location and importance of lipid–protein interactions in the gating of mechanosensitive channels.
A series of quantitative behavioural and opto-physiological analyses using a novel robot microscope system reveals that C. elegans computes the time-differential and time-integral of sensory information for decision-making during olfactory navigation.
Temperature-activated TRPV1 ion channels respond to increased temperatures by opening and then entering an inactivated state from which they cannot recover, suggesting that this form of irreversible gating results from partial unfolding during heat absorption.
The SAGA complex binds non-chromosomal DNA circles and prevents their spreading by attaching them to nuclear pores, thereby leading to the concomitant accumulation of DNA circles and pores in ageing yeast mother cells.
A comprehensive mapping of the proteome and transcriptome during the complete replicative lifespan of budding yeast predicted an increased abundance of the protein biogenesis machinery is most causal for aging.
A protein called SIR-2.1 helps to protect worms from the effects of aging by regulating metabolic processes that would otherwise generate damaging reactive oxygen species.
Aging is a process characterized by gradual metabolome remodeling, deceleration of the remodeling in late life and under conditions that extend lifespan, and a mortality-associated pattern of cumulative damage.
