Different Heterotrimeric G Protein Dynamics for Wide-Range Chemotaxis in Eukaryotic Cells
Chemotaxis describes directional motility along ambient chemical gradients and has important roles in human physiology and pathology. Typical chemotactic cells, such as neutrophils and Dictyostelium cells, can detect spatial differences in chemical ...

Annexin, a Protein for All Seasons: From Calcium Dependent Membrane Metabolism to RNA Recognition
Annexins are an important protein family traditionally well known to bind to phospholipids and to interact with various proteins in a calcium dependent way. More recently, it has been established that a feature common to the family is also to bind to RNA having a role in translation. In bies70019 article, Vedeler et al.

Homeoprotein Hbx4 represses adhesion molecule governing cytokinesis and development [PDF]
Homeobox genes encode proteins with a highly conserved DNA-binding motif and provoke morphological diversification of body segments by differentially controlling the expression of downstream targets.

Self-organized Vortex State in Two-dimensional Dictyostelium Dynamics
We present results of experiments on the dynamics of Dictyostelium discoideum in a novel set-up which constraints cell motion to a plane. After aggregation, the amoebae collect into round ''pancake" structures in which the cells rotate around the center ...

Mathematical models for chemotaxis and their applications in self-organisation phenomena [PDF]
Chemotaxis is a fundamental guidance mechanism of cells and organisms, responsible for attracting microbes to food, embryonic cells into developing tissues, immune cells to infection sites, animals towards potential mates, and mathematicians into biology.

Dictyostelium cells are forest soil amoebae, which feed on bacteria and proliferate as solitary cells until bacteria are consumed. Starvation triggers a change in life style, forcing cells to gather into aggregates to form multicellular organisms ...

Cell Sorting daring Pattern Formation in Dictyostelium [PDF]
Formation of the prestalk-prespore pattern in Dictyostelium was investigated in slugs and submerged clumps of cells. Prestalk and prespore cells were identified by staining with vital dyes, which are shown to be stable cell markers.

OXYGEN GRADIENTS CAUSE PATTERN ORIENTATION IN DICTYOSTELIUM CELL CLUMPS [PDF]
We have investigated the formation of the prestalk-prespore pattern in Dictyottelium discoideum. Pattern formation occurs in clumps of Dictyostelium cells embedded in agar under a 100% oxygen atmosphere.
