A PI3-kinase mediated negative feedback regulates neuronal excitability at the Drosophila neuromuscular junction
Use-dependent downregulation of neuronal activity (negative feedback) can act as a homeostatic mechanism to maintain neuronal activity at a particular specified value. Disruption of this negative feedback might lead to ...
The study of an autocrine signal transduction pathway that represses cell proliferation in Dictyostelium discoideum
Many secreted factors are believed to inhibit cell proliferation in certain tissues such as tumors; however, the identity and action of most of these factors remains unknown. The recent identification of two autocrine ...
Molecular genetic analyses of plant peroxisome functions
Arabidopsis peroxisomes carry out diverse functions, including fatty acid β-oxidation and conversion of indole-3-butyric acid (IBA) to indole-3-acetic acid (IAA). Peroxins are proteins necessary for peroxisome biogenesis; ...
