Anesthesia-Induced Developmental Neurodegeneration: The Role of Neuronal Organelles

Exposure to general anesthetics (GAs) and antiepileptics during critical stages of brain development causes significant neurotoxicity to immature neurons. Many animal, and emerging human studies have shown long-term functional sequelae manifested as behavioral deficits and cognitive impairments. Since GAs and antiepileptic drugs are a necessity, current research is focused on deciphering the me...

Low molecular weight GTP-binding proteins are associated with neuronal organelles involved in rapid axonal transport and exocytosis.

Recent evidence suggests that low molecular weight GTP-binding proteins may play important roles in a variety of membrane transport processes. In order to address the question of whether these proteins are involved in transport processes in the nerve axon, we have assessed their presence in rapid transport membranes from rabbit optic nerve. We report the characterization of a group of low molec...

Combinatorial Marking of Cells and Organelles with Reconstituted Fluorescent Proteins

Expression of GFP and other fluorescent proteins depends on cis-regulatory elements. Because these elements rarely direct expression to specific cell types, GFP production cannot always be sufficiently limited. Here we show that reconstitution of GFP, YFP, and CFP previously split into two polypeptides yields fluorescent products when coexpressed in C. elegans. Because this reconstitution invol...

Mechanisms for the incorporation of proteins in membranes and organelles

Because of the high degree of organizational complexity of eucaryotic cells, it is clear that the implementation of their genetic programs must, in many cases, involve a complex sequence of cotranslational and posttranslational events that are necessary to transfer polypeptides from their sites of synthesis to their sites of function. It is difficult to envisage the existence of a single genera...
