RESUMEN

BACKGROUND AND OBJECTIVES: Determining authorship for publications is often a difficult process, even more so when individuals from several disciplines collaborate with community organizations to conduct projects. Although multidisciplinary and community-academic partnerships provide fertile ground for publication efforts, disputes about authorship and ownership of data may hinder efforts to disseminate information. This article describes a process for dealing with authorship in multi-professional collaborations. It provides an authorship scale, similar to a neonatal Apgar scale, to determine order of authorship in multi-professional projects. Key components or activities in the process of authorship are identified, and points are assigned to each component in proportion to an investigator's level of activity in each component/activity. Scores are summed and can range from 1 to 35 for each author. The order of authorship is then determined by the relative score of each participant.

RESUMEN

The regulation of a gene, designated spot 14, which is rapidly induced in rat liver in response to 3,5,3'-triiodo-L-thyronine (T3) was studied as a model for exploring the molecular basis of thyroid hormone action. The time course of induction of the nuclear precursor to spot 14 mRNA after intramuscular injection of T3 displayed a very short lag period of between 10 and 20 min. The rapidity of this effect suggests that the induction in gene expression occurs as a primary response to the hormone-receptor interaction. The protein synthesis inhibitor cycloheximide injected 15 min before T3 completely blocked the accumulation of nuclear precursor RNA 30 min after T3 treatment. Emetine, an inhibitor of protein synthesis which acts by a different mechanism than cycloheximide, also blocked the induction of the spot 14 nuclear precursor RNA. The increased rate of spot 14 gene transcription observed after T3 treatment, as measured by nuclear run-on assay, was similarly completely abolished in the presence of cycloheximide. In addition, ongoing protein synthesis was required for maintaining spot 14 nuclear precursor RNA at induced levels in animals previously treated with T3. On the other hand, cycloheximide had no effect on T3 uptake or binding to the nuclear receptor during the 45-min time frame studied. The paradox of the rapid kinetics of induction and the requirement of ongoing protein synthesis may be explained by a protein with an extremely short half-life which is necessary for T3 induction of the spot 14 gene.
