Genome-wide measurements on mouse liver cells show that transcription, and a particular key transcription factor, have a smaller than expected influence on the mouse circadian system.
A mathematical model based on enzyme kinetics shows how the relationships between life expectancy, survival rates for children and adults, and national income change over time.
A genome-organizing protein that is present only in the olfactory system of mice has been found to orchestrate changes in the relative numbers of different odor-sensing neurons on the basis of how active these neurons are.
A combination of detailed sampling and mathematical modeling suggests that the response of immune cells to reactivation of herpes simplex virus 2 is extremely rapid and effective within microscopic areas of genital skin.
Nutrient limitation elicits differential responses in cells lacking the tumor suppressor PTEN and in normal cells, resulting in hyperplastic overgrowth of PTEN mutant tissue independent of additional mutations.
Cells that give rise to the infectious form of parasitic flatworms called schistosomes show similar patterns of gene expression to stem cells in free-living flatworms.
Efflux of xenobiotic fluoride from microorganisms occurs through a novel family of ion channels with stringent selectivity for fluoride ion and dual-topology molecular architecture.
Steroid hormone receptors control the expression of their target genes through a digital on-off switch in individual cells, which leads to an analogue dose-response relationship at the level of the whole organism.
