Accurate measurements of the molecular composition single cells will be necessary for understanding relationship between gene expression and function in diverse cell types. One most important phenotypes that differs is their size, which was recently shown to an determinant proteome populations similarly sized cells. We, therefore, sought test if effects size on protein concentrations were also evident single-cell proteomics data. Using relative a set reference proteins estimate cell's DNA-to-cell volume ratio, we found differences explain significant amount cell-to-cell variance two published data sets.

To maintain stable DNA concentrations, proliferating cells need to coordinate replication with cell growth. For nuclear DNA, eukaryotic achieve this by coupling cell-cycle progression, ensuring that is doubled exactly once per cycle. By contrast, mitochondrial typically not strictly coupled the cycle, leaving open question of how correct amount during Here, we show in budding yeast, copy number increases volume, both asynchronously cycling populations and G1 arrest. Our findings suggest cell-volume-dependent maintenance achieved through nuclear-encoded limiting factors, including polymerase Mip1 packaging factor Abf2, whose proportion volume. directly linking protein synthesis thus growth, constant concentrations can be robustly maintained without a for cell-cycle-dependent regulation.

Dynamic changes in cell size are associated with development and pathological conditions, including aging. Although enlargement is a prominent morphological feature of cellular senescence, its functional implications unknown; moreover, how senescent cells maintain their state less understood. Here we show that an extensive remodeling actin cytoskeleton necessary for establishing senescence-associated pro-inflammatory secretory phenotype (SASP). This attributed to balancing act between the SASP regulator GATA4 mechanosensor YAP on expression Rho family GTPase RHOU. Genetic or pharmacological interventions reduce attenuate minimal effect senescence growth arrest. Mechanistically, couples nuclear localization NF-κB via Linker Nucleoskeleton Cytoskeleton (LINC) complex. RhoU protein accumulates mouse adipose tissue under senescence-inducing conditions. Furthermore, RHOU correlates during human Thus, our study highlights unexpected instructive role modulating reveals mechanical branch regulatory network. Senescent accumulate aging exhibit enlargement, function which has been unclear decades. Here, authors identify antagonistic genetic circuit hypertrophy reveal SASP.

Though cell size varies between different cells and across species, the nuclear-to-cytoplasmic (N/C) ratio is largely maintained species within types. A maintains a relatively constant N/C by coupling DNA content, nuclear size, size. We explore how couple division growth to content. In some cases, use as molecular yardstick control availability of cycle regulators. other sets limit for biosynthetic capacity. Developmentally programmed variations in given type suggest that specific required respond physiological demands. Recent observations connecting decreased ratios with cellular senescence indicate maintaining proper essential functioning. Together, these findings causative, not simply correlative, role regulating progression.

Abstract How the production of biomass is controlled as cells increase in size and proceed through cell cycle events important for understanding regulation global cellular growth. This has been studied decades but not yielded consistent results, probably due to perturbations induced by synchronisation methods used most previous studies. To avoid this problem, we have developed a system analyse unperturbed exponentially growing populations fission yeast cells. We generated thousands fixed single‐cell measurements size, stage levels translation transcription. show that scales with additionally, increases at late S‐phase/early G2 early mitosis decreases later mitosis, suggesting controls are also operative over translation. Transcription both amount DNA, level transcription may be result dynamic equilibrium between number RNA polymerases associating disassociating from DNA.

Although polyploidization is frequent in development, cancer, and evolution, impacts on animal metabolism are poorly understood. In Xenopus frogs, the number of genome copies (ploidy) varies across species can be manipulated within a species. Here, we show that triploid tadpoles contain fewer, larger cells than diploids consume oxygen at lower rate. Drug treatments revealed major processes accounting for tadpole energy expenditure include cell proliferation, biosynthesis, maintenance plasma membrane potential. While inhibiting proliferation did not abolish consumption difference between triploids, altered cellular biosynthesis or electrical potential did. Combining these results with simple mathematical framework, propose decrease total surface area lowered production activity components including Na
