Example sentences for: dictyostelium
How can you use “dictyostelium” in a sentence? Here are some example sentences to help you improve your vocabulary:
Two secreted proteins or protein complexes are involved in sensing cell density [ 5 ] . Prestarvation factor (PSF) is a glycoprotein that is secreted when cells are growing and accumulates as an indicator of the ratio of cell density relative to the supply of food [ 6 7 ] . When the ratio of Dictyostelium cells to nutrients is above a certain threshold, PSF induces the expression of several early developmental genes including discoidin I, lysosomal enzymes, and some components of the cAMP pulsing system [ 8 9 ] . Once nutrients are depleted, PSF production declines and a second cell density-sensing pathway is activated.

GCN2 of yeast and mammals is a known sensor of amino acid starvation and regulates cellular responses to such starvation [ 24 25 ] . Using degenerate primers and PCR and database searching identified two GCN2-like genes in Dictyostelium , ifkA and ifkB . Thinking that one or both of these genes may play a role in sensing amino acid starvation and in initiating development, we carried out the work described herein to examine their functions.
Sequences were eventually identified from the Dictyostelium cDNA project in Japan http://www.csm.biol.tsukuba.ac.jp/cDNAproject.htmland the
When the food supply is depleted, Dictyostelium cells shut down growth and cell division and enter a developmental program designed to produce and disperse spores.
