Strokes Of Existence: The Connection Of All Things, Mari Gorman
Graduate Student Publications and Research
Acted or real—and all life is real whether one is acting or not—the common denominator and consistent, ubiquitous reality of life and all behavior is that it manifests in the form of relationships on all scales. But what is a relationship? Until now, the answer to this question has not been sufficiently known. As a result of many years of empirical research that began with the aim of discovering what is going on in a gifted actor when s/he is playing a character that can be observed and experienced as a living, intuitive being, and based on the knowledge that …
Pldb, A Putative Phospholipase D Homologue, Mediates Quorum Sensing In Dictyostelium Discoideum Development, Yi Chen
Dissertations, Theses, and Capstone Projects
Quorum sensing, the ability to measure the local cell density, is required for animal cells to achieve proper cell growth, differentiation and development. However, because of the genetic intractability of mammalian cells, we study quorum sensing in the genetically pliable unicellular eukaryote Dictyostelium discoideum. D. discoideum cells live as individual cells under vegetative conditions. Starvation sets off development to a multicellular organism. But cells won't develop unless enough cells are under starvation conditions. Approximately 105 cells are needed to form a fruiting body, the final stage of the development. When starved, cells are able to calculate the concentration …
