Cell density shows very little variation within a given cell type. For example, in humans
variability in cell density among cells of a given cell type is 100 times smaller than variation …

It was first discovered in 1992 that P-glycoprotein (Pgp, ABCB1), an ATP binding cassette
(ABC) transporter, can transport phospholipids such as phosphatidylcholine,− ethanolamine …

We integrated ubiquity, mass and lifespan of all major cell types to achieve a comprehensive
quantitative description of cellular turnover. We found a total cellular mass turnover of 80±20 …

Animals display substantial inter-species variation in the rate of embryonic development
despite a broad conservation of the overall sequence of developmental events. Differences …

Glucose is vital for life, serving as both a source of energy and carbon building block for
growth. When glucose is limiting, alternative nutrients must be harnessed. To identify …

During growth, cells must expand their cell volumes in coordination with biomass to control
the level of cytoplasmic macromolecular crowding. Dry-mass density, the average ratio of …

Metabolic regulation influences cell proliferation. The influence of pyruvate kinase isoforms
on tumor cells has been extensively studied, but whether PKM2 is required for normal cell …

Methods to rapidly assess cell growth would be useful for many applications, including drug
susceptibility testing, but current technologies have limited sensitivity or throughput. Here we …

Genome-scale models of metabolism can illuminate the molecular basis of cell phenotypes.
Since some enzymes are only active in specific cell types, several algorithms use omics data …

Atmospheric methane oxidizing bacteria (atmMOB) constitute the sole biological sink for
atmospheric methane. Still, the physiological basis allowing atmMOB to grow on air is not …
