Body Size Regulation via BMP Signaling in <i>Caenorhabditis elegans</i>
<p>The body size of an organism can be a crucial determinant of access to nutrition, reproductive success and overall survival in the wild. However, how body size of an individual is determined is incompletely understood. Body size is a complex trait determined by multiple pathways and genes, …

Size regulation of double and half embryos in the mice musculus
… also provided insights into embryonic growth regulation. There is an indication that the embryo can regulate for an increase in size because although aggregation chimeras are twice as big as normal embryos when made, they are born of normal size. Upward regula..... tion of size reduced embryos …

Mechanisms and dynamics of size regulation and lumen formation in mouse double embryos
… in the number of cells and to generate normal-sized pups. It was previously showed that double-sized embryos achieve downsizing after implantation but before gastrulation ensues. However, the exact timing and cellular mechanisms that regulate the morphogenetic events during double embryos …

Cell Size Control in Fission Yeast
… organisms, there is almost much variety in cell size as there is for cell function and cell type. However, within each cell type, cells stay remarkably faithful to a defined size over generations. Many factors have been found to influence this ability to specify and maintain cell size, yet clear …

The socio-ecology and social behaviour of the brown hyaena Hyaena Brunnea, Thunberg, 1820 in the southern Kalahari.
… subadults and nomadic adult males. Territory size is mainly affected by the dispersion pattern of the food in the territory and group size by the "quality" of the food. Mating is carried out between nomadic males and group-living females and group-living males help with the feeding of cubs. …

Integrin Distribution in Collagen Iv Mutants and Use of Rna Interference to Identify a Collagen Iv Receptor in C. Elegans
… targeting the putative receptor gene was hypothesized to phenocpy the collagen IV null phenotype. Observation of dumpy animals suggests that the putative protein is possibly involved in body shape and size regulation. Absence of a significant percent of embryonic lethality as hypothesized from …

Investigation of the role of polyploidization in glial cells during the development of the drosophila nervous system
… differentiation, cell proliferation, and cell size regulation. The proper orchestration of these events ensures that each organ is scaled correctly and can function properly. Polyploidization is a process by which cells increase their DNA content and is used across species to generate large …

The role of the environmental stress response in aneuploid and cell cycle-arrested budding yeast
Size matters in eukaryotic cells. Inability to maintain cell size homeostasis, or the coordination between growth and division, has direct consequences on cellular functions and fitness. Eukaryotic cells have developed mechanisms to ensure proper coordination of biomass accumulation and cell cycle …

On connections between metazoan cellular metabolism and cell size
All animal cells maintain cell size homeostasis, where cell growth (increase in size) is balanced with proliferation (reduction in size via cell division). Yet, different cell types have different sizes and there are physiologically relevant situations where animal cells undergo major cell size …
